About TreatmentsThatWork™
Stunning developments in health care have taken
place over the last several years, but many of our
widely accepted interventions and strategies in
mental health and behavioral medicine have been
brought into question by research evidence as not
only lacking benefit, but perhaps, inducing harm.
Other strategies have been proven effective using
the best current standards of evidence, result- ing
in broad-based recommendations to make these
practices more available to the public. Several
recent developments are behind this revolution.
First, we have arrived at a much deeper
understanding of pathology, both psychological and
physical, which has led to the development of
new, more precisely targeted interventions. Second,
our research methodologies have improved
substantially, such that we have reduced threats to
internal and external validity, making the outcomes
more directly applicable to clinical situations. Third,
gov- ernments around the world, health care
systems, and policy makers have decided that the
quality of care should improve, that it should be
evidence based, and that it is in the public’s interest
to ensure that this happens (Barlow, 2004; Institute
of Medicine, 2001).
Of course, the major stumbling block for clinicians
everywhere is the accessibility of newly developed
evidence-based psychological inter- ventions.
Workshops and books can go only so far in
acquainting responsible and conscientious
practitioners with the latest behavioral health care
practices and their applicability to individual
patients. This new series, TreatmentsThatWork™, is
devoted to communicat- ing these exciting new
interventions to clinicians on the front lines of
practice.
v
The manuals and workbooks in this series contain
step-by-step detailed procedures for assessing and
treating specific problems and diagnoses. But this
series also goes beyond the books and manuals by
providing ancillary materials that will approximate the
supervisory process in assisting practi- tioners in the
implementation of these procedures in their practice.
In our emerging health care system, the growing
consensus is that evidence- based practice offers the
most responsible course of action for the mental health
professional. All behavioral health care clinicians
deeply desire to provide the best possible care for
their patients. In this series, our aim is to close the
dissemination and information gap and make that
possible.
This therapist guide and the companion workbook forclients address the treatment of insomnia. Over onethird of the adult population expe- riences insomnia atleast intermittently and 1 to 2% of the general pop-ulation suffers from primary insomnia (a form ofinsomnia devoid of secondary causes). Primaryinsomnia can have severe negative outcomes for theindividual and has implications for the health caresystem. Medication is often prescribed, but can havesignificant side effects.
Unlike pharmacological approaches, CBT insomniaintervention has been shown to yield long-termimprovements. This guide outlines a safe andeffective treatment that targets the behavioral andcognitive components of insomnia. It includesdetailed instructions for assessment and trou-bleshooting. The corresponding client workbookprovides educational information and homeworkforms. Together, they form a complete insom- niatreatment package for a variety of client needs.
Clinicians will find this a welcome addition to theirarmamentarium.

Background Information and Purpose of This Program
The behavioral component of this treatment manual
originally was prepared as an Appendix to the firstauthor’s ( JDE) National Institutes of Mental Health
funded grant (MH 48187) entitled, “Cognitive-Behavioral Therapy for Treatment of PrimaryInsomnia.” The cognitive component of this manualwas prepared by the second author (CEC) as anAppendix to a grant funded by the National Instituteof Nursing Research (NR 010539) entitled “Cognitive-Behavioral Insomnia Treatment in Chronic FatigueSyndrome.” The primary purpose of this manual is todescribe and operationalize the cognitive-behavioraltherapy (CBT). However, this manual has beenwritten in such a manner as to provide otherinvestiga- tors and clinicians an understanding ofCBT as well as step-by-step instructions forreplicating treatment procedures.
The specific treatment procedures presented hereinhave been derived from various sources. As describedin more detail later in this chapter, the CBT protocolrepresents a “second generation” multicomponentform of therapy that evolved from several decades ofcognitive and behavioral insomnia research. Thistreatment includes selected first generationbehavioral treatment strategies that have provenreasonably effective as stand-alone treatments forinsomnia or for other conditions. However, the CBTprotocol combines several of these therapies toprovide a more omnibus therapy designed to addressthe varying specific treatment needs of the insomnia
patients we encounter. This CBT protocol wasdeveloped from the first author’s early work(Edinger et al., 1992; Hoelscher & Edinger, 1988) andfrom the writings of Bootzin (1977), Morin et al.(1989), Spielman, Caruso, et al. (1987), and Webb (1988).The cognitive component was informed byintegrative cognitive-behavioral models of
1
Morin (1993) and Harvey (2002). One of thecognitive strategies (i.e., Constructive Worry) was
derived from Carney and Waters (2006) and Espie andLindsay (1987). As much of our own and others’research has focused on the type of insomnia knownas Primary Insomnia, the strategies described in thismanual are mainly fashioned for the treatment of thiscondition. However, as discussed in the last chapter ofthis book, these strategies may be considered forother forms of insomnia as well.
This treatment manual is divided into chapters thatdescribe methods of insomnia assessment and theimplementation of our CBT protocol. Each chapterdescribing the treatment protocol provides a“treatment rationale” to be provided to patientsundergoing treatment. Specific information andinstructions to be provided to patients arehighlighted with italics. Investigators who wish toreplicate the procedures described should presentthe highlighted information and instructions totheir patients verbatim. It is also recommended thatthose who wish to use these treatments in their own
insomnia research first review the list of Referencesprovided at the end of this text.
Nature and Significance of Primary Insomnia
The sleep disorder insomnia is characterized by
difficulties initiating, sustaining, or obtainingqualitatively satisfying sleep that occur despiteadequate sleep opportunities/circumstances andresult in notable waking deficits (Edinger et al.,
2004). Over one third of the adult populationexperiences insomnia at least intermittently,
whereas 10% to 15% suffer chronic, unrelentingsleep difficulties. Insomnia may result from variousmedical disorders, psychiatric con- ditions,substance abuse, and other primary sleep disorders
(e.g., sleep apnea). However, 1% to 2% of thegeneral population suffers from primary insomnia, a
form of insomnia disorder that persists either in theabsence or independent of any such comorbidcondition. Whereas the middle-aged and older adultsare most prone to develop one of the many subtypesof insomnia, primary insomnia is the most commondiagnosis found in younger age groups. As such, therisk for develop- ing this condition remainsrelatively stable across the life span. Although
many insomnia sufferers go undetected (Ancoli-Israel &
2
Roth, 1999), primary insomnia is common inprimary care settings and accounts for over 20% ofall insomnia sufferers who present to specialty sleepdisorders centers (Coleman et al., 1982; Simon &VonKorff, 1997). Thus, primary insomnia appearssufficiently preva- lent and disturbing that itfrequently comes to the attention of both sleepspecialists and general medical practitioners.
Since primary insomnia is devoid of secondary causes,this problem was traditionally viewed as less seriousthan those insomnias arising from medical, psychiatric,substance abuse, or other serious sleep disorders(e.g., sleep apnea). However, epidemiologic evidencesuggests insomnia, uncomplicated by comorbidpsychiatric, substance abuse, or medical disorders,substantially increases health-care utilization/costs andaccounts for as many as 3.5 disability days per monthamong affected individuals (Ozminkowski, Wang, &Walsh, 2007; Simon & VonKorff, 1997; Weissman,Greenwald, Nino-Murcia, & Dement, 1997). Also, sev-eral studies have shown that primary insomniadramatically increases subsequent risk for developing adepressive illness, serious anxiety disor- der, orsubstance abuse problem even after other significantrisk factors are controlled (Breslau, Roth, Rosenthal, &Andreski, 1996; Chang, Ford, Mead, Cooper-Patrick, &Klag, 1997; Ford & Kamerow, 1989; Livingston, Blizard,& Mann, 1993; Vollrath, Wicki, & Angst, 1989). Inaddition, primary insomnia contributes to reducedproductivity, acci- dents at work, increased alcoholconsumption, serious falls among older adults, and asense of being in poor health (Brassington, King, &Bliwise, 2000; Gislason & Almqvist, 1987; Johnson,Roehrs, Roth,& Breslau, 1998; Johnson & Spinweber, 1983; Katz &McHorney, 1998). Thus, when encountered clinically,primary insomnia patients warrant safe, effective,and enduring treatment.
Diagnostic Criteria for Primary Insomnia Disorder
Primary Insomnia is a diagnosis specific to the AmericanPsychiatric Association’s sleep disorder classificationsystem outlined in recent versions of its Diagnostic andStatistical Manual of Mental Disorders. This diagnosis firstappeared in the revised, third edition of theAssociation’s Diagnostic and Statistical Manual (AmericanPsychiatric Association, 1987) and has
3
Table 1.1 Diagnostic Criteria for Primary Insomnia
A. The predominant complaint is difficulty initiating or maintaining sleep, or nonrestorative sleep, for at least 1 month.
B.The sleep disturbance (or associated daytime fatigue) causes clinically significant distress or impair-ment in social, occupational, or other important areas of functioning.
C.The sleep disturbance does not occur exclusively during the course of Narcolepsy, Breathing-Related Sleep Disorder, Circadian Rhythm Sleep Disorder, or a Parasomnia.
D.The disturbance does not occur exclusively during the course of another mental disorder (e.g., Major Depressive Disorder, Generalized Anxiety Disorder, delirium).
E.The disturbance is not due to the direct physiologic effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
Taken from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision (DSM-IV-TR, APA, 2000)
been maintained through subsequent revisions of thistext (DSM-IV-TR, American Psychiatric Association,1994, 2000). Primary insomnia’s diag- nostic criteria
listed in Table 1.1 highlight the primary or central rolethat sleep-wake disturbance serves in defining thiscondition. In fact, these criteria specify that aprimary insomnia diagnosis is assigned when theinsomnia does not occur exclusively during the courseof another primary sleep or psychiatric disorder andis not the direct result of a general med- ical disorderor substance use/abuse. As such, primary insomnia isperhaps best conceptualized as a diagnosisestablished by exclusion of other pri- mary andsecondary forms of sleep disturbance. Nevertheless,primary insomnia can usually be discerned fromclinical interview, as expensive and time-consuminglaboratory tests are seldom needed for diagnosis ofinsomnia.
Development of This Treatment Program and Evidence Base
It seems intuitively obvious that practicing good sleep
habits (i.e., follow- ing a routine sleep-wake schedule;
avoiding daytime napping, etc.) and relaxing before
bedtime facilitates nocturnal sleep. As such, it seems
rea- sonable to speculate that psychological and
behavioral strategies designed to improve sleep
habits and reduce bedtime arousal may be use- ful for
treating insomnia. However, not until the late 1950s
did the use-
4
fulness of behavioral interventions receive attentionin the scientific literature. In 1959, Schultz and Luthewere the first to formally report their success intreating a patient with sleep-onset insomnia usingthe form of relaxation therapy (RT) known asautogenic training. Several years later, Jacobson(1964) reported similar results in a case he treatedwith his progressive muscle relaxation. However, notuntil the early 1970s were the first randomizedclinical trials conducted to document the efficacy ofRTs (Borkovec & Fowles, 1973; Nicassio & Bootzin,1974). Although limited in number, these early reportswere sufficient to spawn substantial research andclinical interest in the use of psychological andbehavioral therapies for insomnia treatment duringthe past two decades.
Arguably one of the more monumentalbreakthroughs in behavioral insomnia research wasBootzin’s (1972) observation concerning theimportant role of behavioral conditioning indisrupting or promoting sleep. Indeed, Bootzin wasthe first to suggest that sleep, like other overtbehaviors, should respond to instrumentalconditioning. Consistent with this suggestion, he firstpresented his innovative stimulus control (SC)insomnia treatment in the early 1970s (Bootzin, 1972).In his early reports, he demonstrated that a simple,straightforward operant condi- tioning approachinvolving standardization of the sleep-wake schedule,eliminating daytime napping, and discouragingsleep-incompatible behaviors in the bed andbedroom is particularly effective for treating chronicprimary insomnia. Perhaps both due to its practicalappeal and its general efficacy, SC quickly becameone of the most widely used behavioral insomniatreatments (Lacks & Morin, 1992).
In our early clinical work, we found stimuluscontrol and relaxation therapies moderately effectivefor treating the sleep problems of many of theprimary insomnia patients we encountered.However, these treat- ments also appeared to have
some limitations. Most notably, neither of thesetreatments included specific strategies foraddressing patients’ unhelpful beliefs that served tosupport their sleep-related anxiety and promotemany of their sleep-disruptive habits. In addition,many people with insomnia report that cognitivearousal is the most significant factor in themaintenance of their sleep difficulty (Espie, Brooks,& Lindsay, 1989; Lichstein & Rosenthal, 1980).However, these treatments did not employ specificstrategies shown to be effective for decreasing pre-sleep arousal (Carney & Waters, 2006; Espie andLindsay, 1987). Lastly, these
5
treatments did not specifically address the practice ofspending excessive time in bed displayed by many ofthe patients with sleep maintenance complaints weencountered. Inasmuch as a case series study by
Spielman, Saskin, and Thorpy (1987) showed thatrestricting time in bed led to sleep improvements ina small group of insomnia patients they treated, wethought a truly omnibus insomnia therapy shouldinclude such a strategy. Finally, we noted the needfor specific strategies to enhance patients’treatment adherence. In this regard we found thatpatients seemed more likely to adhere to treatment
recommendations if they were first provided somelimited psychoeducational material designed to givethem a basic understanding of what regulates thehuman sleep system and the types of habits that helpand hinder the normal sleep process.
Given these observations, the need for a
multicomponent cognitive- behavioral therapy for
insomnia became apparent. Thus, we con-
structed a treatment that included a number of
components including(1)a cognitive module designed to provide
psychoeducation about
factors that regulate the human sleep system and toaddress unhelpful beliefs about sleep; (2) standardstimulus control instructions to address patients’conditioned arousal and eliminate common sleepdisruptive habits (daytime napping, maintaining anerratic sleep-wake schedule); and (3) a protocol forlimiting each patient’s time in bed to an individuallytailored time-in-bed prescription (discussed indetail in Chapter 3).
To test this approach, we conducted two small case-series studies using multiple baseline designs. Thefirst of these studies (Hoelscher & Edinger, 1988),which included four primary insomnia patients, pro-vided initial support for our multicomponentapproach in that three of the four patients treatedresponded well once treatment was initiated. In oursecond case series study (Edinger et al., 1992), seven
patients under- went baseline monitoring that variedfrom 2 to 4 weeks in length and then successivelycompleted four weekly sessions of relaxation trainingfollowed by four sessions of our multicomponenttreatment. Results of this latter trial again suggestedthat most patients showed marked improvements inkey sleep measures and such improvements occurredonly after our multicomponent Cognitive-BehavioralTherapy (CBT) was initiated. Shortly thereafter,Morin, Kowatch, et al. (1993) published the firstrandomized clinical trial that showed amulticomponent CBT
6
similar to our approach was effective (compared to a
wait-list condition) for treating older adults with
insomnia.
Since the time of these early works, a number oflarger randomized clin- ical trials have shownmulticomponent CBT insomnia treatment is bothefficacious and clinically effective for treatingprimary insomnia. In efficacy studies (Edinger et al.,2001, 2007; Morin, 1999) conducted with intentionallyrecruited and thoroughly screened primary insomniasamples, CBT has proven superior to relaxationtraining, sham behav- ioral intervention, sleepmedication (tamazepam), a medication place- bo,and a no-treatment (wait-list) for treating insomniacomplaints. In two large effectiveness trials (Espie,2001; Espie et al., 2007) conducted with patients whopresented to primary care clinics with insomnia com-plaints, CBT proved more effective than usualmedical management strategies (medication andsleep advice) for producing sleep improve- ments.Moreover, a recent critical literature review (Morinet al., 2006) concluded that there have been asufficient number of efficacy and effectivenessstudies conducted to conclude that CBT for insomniais a well-established and proven treatment approachparticularly for those with primary insomnia. Thus,with reasonable confidence we can offer thetreatment strategies outlined in this manual as a“Treatment That Works” for patients with thiscondition.
Theoretical Model for Cognitive-Behavioral Insomnia Therapy
Spielman’s model presented in Figure 1.1 provides aconceptual frame- work for understanding theevolution of chronic primary insomnia and the roleof CBT for managing this condition. According tothis model, predisposing factors, precipitating events,and perpetuating mech- anisms all contribute to thedevelopment of chronic primary sleep difficulties.
Some individuals may be particularly vulnerable tosleep difficulties either by virtue of having a“weak,” “highly sensitive,” biological sleep systemor personality traits that dispose them to poor sleepwhen confronted with stress. When such individualsare con- fronted with the proper precipitatingcircumstances (e.g., a stressful life event, suddenunexpected change in their sleep schedule), theytend to develop an acute sleep disturbance.

Spielman’s model describing the evolution of chronic primary insomnia
turn, may then be perpetuated by a host of
psychological and behav- ioral factors that emerge
in reaction to such a sleep difficulty. Thus, although
predisposing and precipitating factors contribute to
the ini- tial development of insomnia, the
psychological and behavioral per- petuating factors
that sustain it serve as the treatment targets for
behavioral insomnia therapy.
The cognitive behavior model posits that an interplayof cognitive and behavioral mechanisms act as thekey perpetuating mechanisms for pri- mary insomniapatients. Setting the stage for sustained sleep difficultyis a thinking style that can include misattributionsabout the causes of insom- nia, attentional bias forsleep-related stimuli, worry and/or rumination aboutthe consequences of poor sleep, and unhelpful beliefsabout sleep promoting practices (Carney & Edinger,2006; Carney et al., 2006; Edinger, et al., 2000; Espie,
2002; Harvey, 2002; Morin, 1993; Morin, Stone,Trinkle, Mercer, & Remsberg, 1993). These cognitions,in turn, sup- port and sustain sleep-disruptive habitsand conditioned emotional responses that eitherinterfere with normal sleep drive or timing mecha-nisms or serve as environmental/behavioral inhibitors
to sleep (Bootzin, 1977; Morin, 1993; Spielman, Saskin,& Thorpy, 1987; Webb, 1988). For example, daytime
napping or spending extra time in bed in pursuit ofelu- sive, unpredictable sleep may only serve tointerfere with the body’s home- ostatic mechanismsthat operate automatically to increase sleep drive inthe face of increasing periods of wakefulness (i.e.,sleep debt). Alternately, the
8
habit of remaining in bed well beyond the normalrising time following a poor night’s sleep may disruptthe body’s circadian or “clock” mechanisms thatcontrol the timing of sleep and wakefulness in the24-hour day. Additionally, the repeated association ofthe bed and bedroom with unsuc- cessful sleepattempts may eventually result in sleep-disruptiveconditioned arousal in the home sleepingenvironment. Finally, failure to discontinue mentallydemanding work and allot sufficient “wind-down”time before bed may serve as a significant sleepinhibitor during the subsequent sleep period. In sum,all these factors may contribute to and perpetuatePI (Bootzin & Epstein, 2000; Edinger & Wohlgemuth,1999; Hauri, 2000; Morin, Savard & Blias, 2000). As aresult, our CBT approach is designed to modify therange of cognitions and sleep-related behaviors thatostensi- bly sustain or add to patients’ sleep problems.
Risks and Benefits of CBT for Insomnia
Although systematic studies of CBT-related sideeffects have not been conducted, the experience basewith CBT-based insomnia interventions suggests thisintervention is a safe and effective treatment modality.This is not to say that side effects do not occur, butthose that do occur are generally transient andmanageable with strategies outlined later in thismanual. Perhaps the most common side effect isenhanced daytime sleepiness during the initial stagesof treatment resulting from restricting patients’ timesspent in bed. In some patients the initial suggestedrestric- tion in time in bed results in mild partial sleepdeprivation and, thus, ele- vated daytime sleepiness.This sleepiness is usually transient and corrected bygradual increases in time in bed. Some patients alsoshow elevated anxiety about sleep when limits areplaced on their times spent in bed and choices of risetimes. This side effect also is easily managed via somerelax- ation of the treatment protocol as discussed in
more detail in Chapter 5.
In contrast, there are many benefits to this
treatment program. As discussed, our CBT
treatment is fashioned to address and eradicate the
various cognitive and behavioral mechanisms that
presumably sustain insomnia and, thus enhance
chances for sustained improve- ments long after
treatment ends. The fact that this actually occurs is
supported by the long-term follow-up data
reported in CBT trials
9
showing sustained treatment benefits up to 24
months after active treatment (i.e., facilitator
contact) concludes. As such, this treatment differs
from most pharmacological approaches (i.e.,
sleeping pills) that provide symptomatic relief but
fail to address the cognitive and behavioral factors
that sustain insomnia. Indeed, there are currently
no data available to show that sleep improvements
persist long after pharmacotherapy for insomnia is
discontinued.
In addition to this benefit there are some data thatindicate many patients may prefer CBT overmedicinal approaches. For example, results of onestudy (Morin et al., 1999) showed patients weremore satisfied with behavioral insomnia therapy andrated it as more effective than sleep medication.Findings from another study (Morin et al., 1992)suggested that patients with chronic insomnia bothpreferred CBT to pharma- cotherapy but alsoexpected that CBT would produce greater improve-ments in daytime functioning, better long-termeffects, and fewer negative side effects. Collectively,these data suggest that insomnia patients regardbehavioral insomnia therapy as a viable andacceptable treatment for their sleep difficulties.
Alternative Treatments
Various “stand-alone” behavioral strategies includingrelaxation therapies, stimulus control, sleeprestriction, and paradoxical intention have provenefficacy for management of insomnia and currentlyare regarded as “well- established” insomniatreatments (Morin et al., 2006). Each of these ther-apies addresses a specific subset of insomnia-perpetuating mechanisms. In addition to thesetherapies, cognitive therapy and sleep hygieneeducation are often employed in insomniamanagement but these therapies do not currentlyhave empirical support as “stand-alone” interventions.
Detailed descriptions of all of these treatments andtheir applications can be found in a number ofsources (e.g., Morin et al., 2006; Edinger & Means,2005; Edinger & Wohlgemuth, 1999). As notedpreviously, we have found our multicomponenttherapy to be a more comprehensive and consistentlyeffective behavioral approach because it is designedto address the cogni- tive and behavioralmechanisms that perpetuate insomnia in the vastrange of primary insomnia patients we encounter.
10
Other non-medicinal approaches for insomnia
management have includ- ed forms of yoga and
acupuncture. Both of these treatments have shown
some efficacy but neither treatment enjoys the sizable
research support that the behavioral insomnia
therapies have acquired. Moreover, access to these
interventions as applied to insomnia may be much
more limited than cur- rent access to the behavioral
therapies. Recently, pre-market testing of sev- eral
investigational devices for insomnia treatment has
begun but such devices have not yet received FDA
approval for insomnia management. Nonetheless,
since it is likely devices may be available in the
future, their efficacy relative to current insomnia
therapies will need to be evaluated.
Role of Medications
The most commonly prescribed sleep medications
are benzodiazepine receptor agonists (BzRA). These
include several benzodiazepines (e.g., temazepam)
as well as newer non-benzodiazepine agents (e.g.,
zolpidem, eszopiclone, zaleplon) that act at the same
site on the
GABAA receptor complex. In addition, sedating
antidepressant drugs such as trazodone (TRZ) andvarious sedating tricyclic antidepres-
sants (e.g., doxepin) have been widely used for
insomnia manage- ment. Finally, the melatonin
agonist ramelteon, has recently been approved for
treatment of insomnia.
The benefit of medications and particularly the BzRAs
is that they have immediate effects on sleep. As such,sleep medications have their great- est advantageover CBT for managing acute and brief forms ofinsom- nia. For example, sleep medications are wellsuited for treatment of insomnia arising from anabrupt sleep-wake schedule change (e.g., jet lag) oras a stress reaction (e.g., bereavement) tounfortunate life cir- cumstances. In contrast, the
role of medications in the management of chronicinsomnia has been debated. Recently some studies
(Krystal et al., 2003; Roth et al., 2005) have showncontinued efficacy of some medications when taken
continuously for periods up to 12 months in duration.However, tolerance and consequent reduced
efficacy may emerge with continued use of somesleep medications, and all sleep medications holdthe risk of psychological dependence when used overtime. Furthermore, whereas medications mayreduce sleep-related
11
anxiety for some patients, pharmacologic treatment,
in general, is not designed to address the range of
cognitive and behavioral insomnia- perpetuating
mechanisms mentioned previously.
Of course, the relative value of BzRA and CBTtherapies largely depends upon their comparativeefficacies for short- and long-term insomniamanagement of PI and CMI patients. Unfortunately,there are currently limited data that speak to therelative efficacy of these two treatment modalities.One recent study (Sivertsen et al., 2006) compared CBTwith the sleep medication zopiclone and showed CBTproduced significantly better short- and longer-termimprovements on objective indices taken fromelectronic sleep recordings but not on subjectivemeasures taken from sleep logs. Some other studies(e.g., Jacobs et al., 2004; Morin et al., 1999) thatcompared treatments consisting of a sleepmedication alone, CBT alone, and a combined CBTand sleep medication therapy showed little differencein short-term outcomes, but superior longer-termoutcomes with CBT alone compared to medicationand combined treatment. However, all of thesestudies are limited by their small sample sizes, use offixed-dose, and fixed-agent pharmacotherapy strategiesthat do not repre- sent standard clinical practice.Thus, additional studies of the relative values ofCBT and sleep medications would be useful.
Treatment Program Outline
The treatment described in the manual should be
preceded by a thor- ough insomnia assessment as
described in Chapter 2. This assessment session
should be conducted to ensure that the patient is
suitable for CBT and to instruct the patient in
collecting the baseline sleep log data needed in the
initial stages of treatment. The subsequent treat-
ment sessions are then employed to address a range
of behavioral and cognitive treatment targets
(perpetuating mechanisms). The following outline
shows the organization and flow of the overall
assessment and CBT insomnia intervention.
I. Pretreatment Assessment
a. Assess nature of insomnia and appropriateness for CBT
b. Assign baseline (pre-therapy) sleep log monitoring
12
II. Presenting Primary Behavioral Treatment Components – Session 1
a. Present treatment rationale and sleep education module
b. Present sleep rules – behavioral insomnia regimen
c. Calculate initial time in bed prescription
d. Assign homework
III. Presenting Cognitive Therapy Strategies – Session 2
a. Review and comment on sleep log findings
showing progress and adherence
b. Provide cognitive rationale to patient
c. Discuss Constructive Worry technique
d. Discuss use of Thought Records
e. Assign homework
IV. Follow-Up/Troubleshooting – Session 3 and Onward
a. Adjusting time in bed recommendations
b. Review and reinforce treatment adherence
c. Troubleshooting – behavioral component
d. Troubleshooting – cognitive component
Use of the Workbook
e. Consideration of therapy termination
A patient workbook has been prepared to
accompany the treatment manual. This workbook
includes much educational information designed to
reinforce what is presented in the treatment
sessions. The workbook also includes various blank
forms such as the sleep log, constructive worry
sheet, and thought record form that patients will
use to complete their assigned therapy “homework”
from week to week. Since reference will be made
to sections of the workbook
13
during the course of therapy, it is recommended that
the patient bring the workbook to each CBT session.
However, in the event the patient fails to do so, it is
suggested that the therapist have a workbook and
blank copies of the various forms mentioned
available to reference at each session.

Chapter 2 Pretreatment Assessment
There are various methods you can use to diagnoseand assess Primary Insomnia (PI) as well as otherforms of insomnia. The following sections brieflydiscuss each method.
Clinical Interview
The clinical interview is a particularly importantcomponent of an insomnia assessment because itprovides the basis from which the clini- cianascertains etiological factors and formulates atreatment plan. In addition to providing acomprehensive assessment of the individual’sspecific insomnia complaint and sleep history, theclinical interview should include evaluation ofmedication and substance use as well as
identification of contributory medical and psychiatricconditions.
Essential elements of an insomnia-focused clinicalassessment are outlined in Table 2.1. As suggested bythe information shown in the table, the insomnia-focused interview should provide a thoroughdescriptive and functional assessment of the sleepcomplaint, its history, and the psycho- logical andbehavioral factors that may sustain it. Moreover, theinterview should provide a thorough assessment ofthe relationship, if any, between comorbid conditions(medical or psychiatric) and the insomnia com-plaint. To facilitate the insomnia assessment, thepatient may be asked to complete a sleep historyquestionnaire like the one provided in the appen- dix
prior to the interview. This sort of instrument isdesigned to gather the pertinent information neededfor a thorough insomnia assessment. Clinicians mayalso choose to employ one of the available semi-
structured interviews (Spielman & Anderson, 1999;Savard & Morin, 2002) designed specifically forinsomnia to guide their inquiries. Whatever
15
method chosen for querying the insomnia sufferer,
an interview with his or her bed partner about the
patient’s sleep pattern and habits can reveal
important diagnostic information such as symptoms of
other sleep disorders.

Sleep Logs
Prior to providing any treatment instructions, it isuseful to have the patient monitor his or her sleep
pattern for a period of at least 2 weeks using a sleeplog. Blank copies of the sleep log we use are pro- videdfor the patient in the corresponding workbook and asingle blank copy of this log is shown in Figure 2.1.This instrument is a par- ticularly valuable tool thatallows for prospective monitoring of the patient’s sleephabits and pattern over time. The log is designed tosolicit information relevant to each night’s sleepincluding whether any naps were taken the previousday, whether any medication or alcohol was ingestedat bedtime to facilitate sleep, the time the patiententered bed, the time the lights were turned off andthe patient attempted to fall asleep, the number ofminutes it took to fall asleep, the number and length
of awakenings during the night, the time of the finalmorning awakening, and the time of actually arisingfrom bed. The log also queries about the quality ofeach night’s sleep and how well rested the patient
felt upon waking. As may be noted from Figure 2.1,the log is designed to allow entry of 1 week’s worth ofsleep information on a single sheet. To ensure thegreatest accuracy and use- fulness of the dataobtained, the patient should be encouraged tocomplete the sleep log each morning within the first 30
minutes or so after arising.
We find the sleep log is the quintessential tool in our
work with insom- nia patients since it provides much
useful assessment information and it guides the
implementation of our cognitive and behavioral
therapy strategies. As an insomnia assessment tool,
the log provides important information about the
patient’s sleep-disruptive habits as well as some
insights into implicit cognitive treatment targets. In
some instances, sleep log data may also be useful for
identifying diagnostic subtypes who may not be good
candidates for the treatment program described in
this guide. To demonstrate the specific types of
information that may be gleaned from the sleep log,
the ensuing discussion provides a number of case
examples.

Case Example #1
Figure 2.2 shows one week of sleep log data for an
individual who manifests a practice seen all too
frequently among our insomnia patients. This
individual shows a pattern of retiring to bed for
the evening well in advance of the actual time
chosen for beginning the night’s sleep. During
review of the sleep log with the therapist, the
patient noted a practice of watching television in
bed for an hour or more before intending to fall
asleep. This practice resulted in the patient
spending 9 or more hours in bed many nights during
the week and usually experiencing extended
awakenings during the course of the night. Careful
querying, however, led to the discovery that the
patient often dozed off while watching TV in bed well
before the des- ignated “lights-out” time indicated
on the sleep log. In such a patient, the excessive
time spent in bed, using the bed for activities other
than sleep, and the unrecorded “dozing” are
important behavioral treat- ment “targets”
uncovered by these sleep log data. The observed
behav- ioral pattern also may herald underlying
misconceptions the patient may have about sleep
needs and sleep-promoting practices that should be
addressed in treatment.
Case Example #2
Figure 2.3 highlights another pattern commonly
seen among insom- nia patients. The most obvious
problem shown by this log is the patient’s erratic
sleep pattern. Indeed, the information recorded
shows that the patient’s bedtimes varied by over 5
hours whereas the chosen rise times varied by
over 3 hours during the week shown. The resulting
sleep pattern shown accordingly is erratic and,
from the patient’s perspective, highly
unpredictable. Patients who show such patterns
often stray from a routine sleep-wake schedule in
an effort to get what sleep they obtain, whenever
they are able to obtain it. Hence, if they are able to
sleep in an extra few hours following a disrupted
night with extended waking periods, they do so to
make up for the sleep they feel they lost during the
night. Unfortunately, this practice only helps sustain
the insomnia. As might be surmised from this
discussion, both the noted erratic sleep pattern
and the sleep- related beliefs and anxiety that
underlie this pattern are treatment targets that the
sleep log has helped uncover.

Figure 2.3
Sleep Log Case #221
Case Example #3
Figure 2.4 highlights the diagnostic usefulness of
sleep log data. These data were collected by a
college student who presented to our clinic
complaining about extreme difficulty falling asleep
each night. This log clearly shows that the student
has marked difficulty getting to sleep on most nights.
Throughout the week, the student takes 2.5 to 3.5
hours to fall asleep despite the use of alcohol as a
sleep aid on several nights. As a result, the usual
sleep onset time on most weekday nights occurs
between 2:30 and 3:30 AM. However, on weekend
nights when the stu- dent chooses a bedtime more
proximal to this usual sleep onset time, the sleep
latency is markedly reduced. Moreover, the weekend
rise times occur much later and afford the student
greater opportunity to obtain a full night’s sleep
given the delayed time of sleep onset. All these
indica- tors suggest the student likely suffers from
delayed sleep phase syn- drome, a circadian rhythm
disorder wherein the endogenous sleep-wake rhythm
is markedly phase delayed. As such, the student is
biologically disposed to fall asleep in the early
morning hours and sleep through much of the
morning if allowed to do so. However, on weekdays
the student is required to arise to attend morning
classes, so the sleep peri- od is artificially shortened
on these days. Patients with this sort of sleep
problem typically require treatments other than the
one described in this guide, so data such as what is
shown in Figure 2.4 are useful for identifying
patients who are not good CBT candidates.
As the treating clinician, you will likely find these
logs useful for iden- tifying the most salient
treatment targets in each of your insomnia
patients. As described in greater detail in the
ensuing chapter, you will use completed sleep logs
to develop patient-specific Time in Bed Prescriptions
(TIB) as part of your treatment recommendations
(see Chapter 3 for more detail).
Insomnia Symptom Questionnaire
The Insomnia Symptom Questionnaire (ISQ)developed by Spielman et al. (1987) is a 13-item self-report instrument designed to assess sleep (e.g.,sleep onset difficulty, wakefulness during sleep) andwaking (e.g., daytime fatigue, sleep worries)symptoms of insomnia. Each item

is accompanied by a 100-mm visual-analog scale (i.e.,horizontal line) that is labeled “not at all” at its leftextreme and “always” at its right extreme. Inresponding to this instrument, respondents draw avertical line through the point on each item’s analogscale (i.e., 100-mm line) to indicate their responses.The distance from the left end of the line to asubject’s response line serves as an analog measureof the degree to which the respondent has thesymptom noted by the item. The mean score across
all 13 items constitutes the measure to be used in thisstudy. In our previous work (Edinger, et al., 2001;
Edinger & Sampson, 2003), we have found the ISQhas acceptable internal consistency (Cronbach’sa. = 0.73) and sensitivity to treatment-related sleepimprovements. Inour research we have used a total ISQ score < 41
as the clinical cutoff connoting insomnia remissiongiven our early findings suggested this cutoff has a92% sensitivity and 64% specificity for discriminatingnor- mal sleepers from primary insomnia sufferers.However, in more recent unpublished work with alarge validation sample, we have determined that anISQ total score < 36.5 may be a better benchmarksince this cutoff has an 89% sensitivity and 86.5%specificity for discriminating patients with primaryinsomnia from normal sleepers.
Insomnia Severity Index
The Insomnia Severity Index (ISI: Morin, 1993) is a 7-item questionnaire that provides a global measure ofperceived insomnia severity based on the followingindicators: difficulty falling asleep, difficulty stayingasleep, and early morning awakenings; satisfactionwith sleep; degree of impair- ment with daytimefunctioning; degree to which impairments arenoticeable; and distress or concern with insomniasymptoms. Each item is rated on a 5-point (0 to 4)Likert scale and the total score ranges from 0–28. Thefollowing guidelines are recommended for
interpreting the total score: 0–7 (no clinicalinsomnia), 8–14 (sub-threshold insomnia), 15–21
(insomnia of moderate severity), and 22–28 (severeinsomnia). The ISI has good internal consistency(Cronbach’s alpha = 0.91) and test- retestreliability (r = 0.80). It has been validated againstsleep logs and electronic sleep recordings (Bastien,Vallieres, & Morin, 2001) and has proven sensitive totherapeutic changes in several treatment studies ofinsomnia (Morin et al., 1999). In recent years, theISI has become
24
increasingly popular in insomnia work and now isrecommended as a standard assessment tool ininsomnia research studies (Buysse et al., 2006).Since the ISI has the mentioned guidelines for scoreinterpreta- tion, this instrument can be used easily inclinical venues for judging ini- tial insomnia severityand the clinical significance of improvementsachieved during insomnia treatment.
Pittsburgh Sleep Quality Index (PSQI: Buysse et al., 1989)
This instrument, like the ISI, is a widely used andcurrently recom- mended (Buysse et al., 2006) tool forassessing sleep disturbance in insomnia patients aswell as in patients with other types of sleep disor-ders. The PSQI is composed of four open-endedquestions and 19 self- rated items (0–3 scale) assessingsleep quality and disturbances over the previous 1-month interval. Domains assessed include sleep onsetlatency, sleep duration, sleep efficiency (i.e., theproportion of time in bed that is actually spentasleep), sleep quality, disturbances to sleep,medication use, and daytime dysfunction. Asummation of these seven component scores yields aglobal score of sleep quality, ranging from 0 to 21.Previous research (Buysse et al., 1989) has shown thata PSQI total score of > 5 has good sensitivity(89.6%) and specificity (86.5%) in discriminating thosewith insomnia from good sleepers. As such, aposttreatment PSQI score < 5 has been used in somestudies as indicat- ing insomnia remission. However,it should be noted that the PSQI provides a globalsleep quality assessment and is not specifically orexclusively designed for insomnia assessment.Moreover, we (Carney et al., 2006) have found thatelevated levels of anxiety may contribute to PSQIscore elevations in some types of insomnia patients.Hence, the patient’s anxiety level at the time of PSQIadministration should be considered when interpretingthe summary score obtained.
Dysfunctional Beliefs and Attitudes About Sleep Questionnaire (DBAS)
This instrument is a valuable tool for identifying
unhelpful sleep-related beliefs and attitudes
presumed to help perpetuate insomnia problems.
Currently both the original parent version and an
abbreviated version are
25
available for clinical and research use. The originalDBAS-30 includes 30 items that comprise five subscalesdesigned to assess (1) attributions about the effects ofinsomnia (e.g., “I am concerned that chronic insom- niamay have serious consequences on my physicalhealth”); (2) percep- tions of loss of control andunpredictability of sleep (e.g., “I am worried that I maylose control over my abilities to sleep”); (3) perceivedsleep needs and sleep expectations (e.g., “Because I amgetting older, I need less sleep”); (4) misattributionsabout causes of insomnia (e.g., “I feel insom- nia isbasically the result of aging and there isn’t much thatcan be done about this problem”); and (5) expectationsabout sleep-promoting habits (e.g., “When I don’t getthe proper amount of sleep on a given night, I need tocatch up the next day by napping or the next night bysleeping longer). A 100-millimeter (mm) analog scale(i.e., horizontal line) labeled “strongly disagree” at itsfar left extreme and “strongly agree” at its far rightextreme accompanies each item and is used byrespondents to indi- cate their degree of endorsement.When completing the DBAS-30, respondents arerequired to draw a vertical line through the point onthe 100-mm scale to indicate their degree of agreementor disagreement with each item. The distance in mmbetween the far left extreme of the analog scale andthe response line then is used as the item’s “score.”With one exception all items are structured so thathigher scores (i.e., stronger item agreement) connotemore dysfunctional beliefs.
Recently an abbreviated 16-item version (DBAS-16) of theoriginal DBAS-30 has become available. This abridgedversion is similar in for- mat to the original instrumentbut it uses 10-point Likert scales super- imposed onvisual analog scales for indicating agreement/disagreement with the various items. For each of the 16
beliefs, the number correspon- ding to the degree ofbelief (e.g., 10 = agree completely) is circled. Atotal score is calculated by summing the item scoresand dividing the resultant sum by 16 (i.e., a mean itemscore). Both the DBAS-30 and DBAS-16 have shownacceptable levels of internal consistency
(Cronbach’s a. values > .80). Furthermore werecently have found DBAS-16 total scores > 3.8 tobe suggestive of the level of unhelpful beliefs commonamong individuals with clinically significant insomniaproblems. Both DBAS instruments can be used toidentify specific prob- lematic beliefs to target intreatment and to assess belief changes result- ing fromour cognitive-behavioral intervention.
26
Epworth Sleepiness Scale
The Epworth Sleepiness Scale is an eight-item self-reportquestionnaire designed to assess daytime sleepiness incommon day-to-day situations such as “Watching TV” or“Sitting and talking to someone.” Respondents areinstructed to indicate how likely they are to fallasleep in each situation using a 4-point rating scale (0= “would never doze” to 3 = “high chance ofdozing”). The ESS score is obtained by sum- ming allitem responses so scores may range from 0 to 24 withhigher scores suggesting greater daytime sleeptendency. A score of 10 or more is considered toindicate clinically significant daytime sleepiness. A scoreof 18 or more connotes someone who is very sleepy. Thisinstru- ment has shown very acceptable internalconsistency (Cronbach’s a. = 0.88) and test-retestreliability (r = .82) within both non-complaining groupsand in groups of clinical sleep-disordered patients (Johns,1991; Johns, 1994) Additionally, Epworth ratings havebeen found to correlate significantly (r = -.514, p< .01) with objective tests of daytime sleepi- ness (Johns, 1991).
Whereas some insomnia patients will obtain scores in
the “sleepy” range on this instrument, they
commonly do not obtain scores indicating they are
very sleepy. Overweight patients who report loud
nocturnal snoring and who score above the clinical
cutoff are likely to suffer from sleep apnea and
should be referred to a sleep specialist for thorough
evaluation of this possibility.
Other Psychological Testing
Because depressed mood and anxiety symptoms are
common among insomnia patients, routine
psychological screening is often recom- mended.
Brief psychological questionnaires such as the
current version of the Beck Depression Inventory
(BDI-II), the Beck Anxiety Inventory, the
Spielberger State-Trait Anxiety Inventories, and
the Brief Symptom Inventory are all useful in this
regard. Although they have limited value when
used in isolation, these questionnaires may provide
important supplemental information not apparent
from the clinical interview.
27
In some cases, it may be necessary to conduct amore thorough psychological assessment. TheMinnesota Multiphasic Personality Inventory-2(MMPI-2) is an extensive psychologicalquestionnaire that produces personality profiles fora wide range of psychopathol- ogy. Validity scalesprovide information on response biases such aspatients’ attempts to either deny or exaggeratepsychopathological symptoms. Individuals withinsomnia produce specific MMPI-2 profilescharacterized by depression, anxiety, andsomatization of emotional conflict. While somesleep disorders centers routinely administer theMMPI-2 to all patients as part of the intakeevaluation, it may be considered too lengthy andtime-consuming for some venues.
Actigraphy
Actigraphy is another technique to assess sleep-
wake patterns over time. Actigraphs are small,
wrist-worn devices (about the size of a wristwatch)
that measure movement. They contain a
microprocessor and onboard memory and can
provide objective data on daytime activity.
Computer software that accompanies most brands
of acti- graphs include scoring algorithms for
estimating sleep and wake time for each night the
actigraph is worn. Most such software also allows
for outputting a day-to-day plot of the sleep-wake
schedule when the patient is asked to wear the
actigraph day and night for a series of days.
Actigraphy is used to clinically evaluate insomnia,circadian rhythm sleep disorders, excessivesleepiness, and restless leg syndrome. It is also used
in the assessment of the effectiveness of treatmentsfor these disor- ders, including behavioral therapy.
Actigraphy has not traditionally been used in routine
diagnosis of sleep disorders but is increasingly being
employed in sleep clinics to replace full
polysomnography. Its greatest value may be that of
providing an object verification of the patient’s sleep-
wake schedule and adherence to recommended
rising times and TIB prescriptions included in the
treat- ment recommendation discussed in the next
chapter.
28
Polysomnography
Polysomnography is a diagnostic test during which a
number of physi- ologic variables are measured and
recorded during sleep. Physiologic sensor leads are
placed on the patient in order to record the following:
Brain electrical activity
Eye and jaw muscle movement
Leg muscle movement
Airflow
Respiratory effort (chest and abdominal excursion)
EKG
Oxygen saturation
This test is typically conducted in a sleep disorders
center but it can also be conducted in the patient’s
home setting. In most cases, polysomnog- raphy is
not necessary for diagnosing insomnia, although in
some cases it is helpful in determining whether or
not there is a medical reason for the patient’s sleep
problems (e.g., sleep apnea or periodic limb move-
ments during sleep).
Summary
In summary, the evaluation of insomnia is a complex
process that may include a variety of assessment
procedures. In most cases of primary insomnia, the
information needed for diagnosis and treatment
decision- making can be gleaned from the clinical
interview and sleep log. Indeed, these two sources
usually provide sufficient information to identify
pertinent cognitive and behavioral treatment
targets in the insomnia patient. However, the
additional assessment methods men- tioned herein
may provide much needed diagnostic and
assessment information in selected cases of primary
insomnia as well as with other insomnia patients
who have underlying sleep disorders or complex
comorbid disorders.

Treatment Rationale
Use the information from Chapter 1 to present the clientwith a brief overview of Cognitive-Behavioral Therapy(CBT) for Primary Insomnia (PI). Review with thepatient Spielman’s 3-P model of insomnia and how itsuggests that predisposing factors (e.g., biological orpersonality traits) and precipitating events (events orcircumstances that are stressful or otherwise disruptive
to normal sleep-wake routines) can lead to thedevelopment of
31
sleep problems. These problems are then made worse
by various perpetuat- ing mechanisms including
unhelpful misconceptions about sleep, anxiety about
sleeping poorly, conditioned arousal to the bed and
bedroom, and various sleep disruptive habits (e.g.,
daytime napping, spending excessive time in bed).
Explain that this treatment program is designed to
correct those unhelpful sleep-related beliefs and
anxiety as well as common sleep- disruptive habits
that maintain or contribute to insomnia.
You may use the following sample dialogue:
We have conducted a thorough evaluation of your sleep problem, and based on our findings we believe you will benefit from some informa- tion about sleep and some recommendations designed to help you change your sleep habits. When sleep problems linger on, as they have in your case, usually unhelpful sleep-related beliefs and habits develop and add to the sleep problem. The treatment you receive will educate you about your sleep problem and help you correct those unhelpful beliefs and habits you have so that you can again develop a more nor- mal sleep pattern.
Then, move on to providing the patient withinformation about sleep.
Sleep Education
The sleep education provided to patients during CBT
has two primary functions. First, it helps patients
overcome their misconceptions and anxiety-
provoking beliefs about sleep so that they may
develop realistic sleep expectations. Also, it enables
patients to better understand the rationale for the
behavioral regimen used in this treatment. This
under- standing, in turn, increases the likelihood
that patients will adhere to treatment
recommendations.
During this first session of treatment, provide the
patient with informa- tion on sleep norms, circadian
rhythms, the effects of aging on sleep, and sleep
deprivation. If you wish, you may audiotape this part
of the session and give a copy of the tape to the
patient to review at home. This information also
appears in the corresponding patient workbook. You
may use the following sample dialogue:

This treatment will require you to make some major changes in your sleep habits so you can improve your sleep. However, before you learn these new habits, it isimportant that you have a better understanding of yoursleep needs and what controls the amount and quality of sleep you obtain. The information I’m about to give you will help you understand how your body’s sleep system works and prepare you for the specific treatment suggestions you will be given.
Before you make any changes in your sleep habits, it is important that you ask the question, “How much sleep do I need each night?” Generally speaking, there is no one amount of sleep that “fits” everyone. Most normal adults sleep 6 to 8 hours per night. However, some people need only 3 or 4 hours of sleep each night, whereas others require 10 to 12 hours of sleep on a nightly basis. At this point, it is important to set aside any previous notions or beliefs you might have about your sleep needs. These beliefs may be wrong and may hinder your progress. The treatment we give you will help you discover the amount of sleep that satisfiesyour needs and lets you feel alert and energetic during the day.
In addition to getting rid of any old ideas you have about your sleep needs, it is important that you learn some things about how your body’s sleep system works. People, like many animals, have powerful internal “clocks” that affect their behavior and bodily functioning. The “body clock” works in roughly a 24-hour period and produces 24-hour cycles in such things as digestion, body temperature, and thesleep-wake pattern. For example, if we record a person’s body temper- ature for several days in a row, we will see a consistent up and down pattern or rhythm in temperature across each 24-hour day. The temperature will be at its lowest point around 3 or 4 AM, will rise throughout the morning and early afternoon, and will hit its peak around 3 or 4 PM. Then, once again the temperature will begin to fall until it hits its low point in the early morning hours.
The influence of the internal circadian clock on the sleep-wake cycle is apparent if one studies the
relationship between the body’s 24-hour tem- perature rhythm and the timing of the sleep period. Suppose a person is placed in a place like a cave, away from daylight, external clocks, and all other time-of-day indicators. In this situation, the person will con- tinue to show a consistent temperature rhythm and sleep-wake pattern that complete a full cycle about every 24 hours. In most people, there is
33
a close relationship between the temperature cycle and the sleep-wake pattern they show. This relationship is shown in the Circadian Temperature Rhythm graph included in your workbook.
(Direct the patient to the graph in the workbook or show himFigure 3.1.)
As shown by this graph, the main sleep period begins when the body temperature is falling and later ends after the body temperature begins rising again. Hence, although the 24-hour temperature cycle shown does not control the human sleep-wake pattern, the tempera- ture rhythm reflects the working of the bodyclock and can be used to predict when sleep is likely to occur in the 24-hour day.
In the real world, work schedules, meal times, and other activities work together with our body clocks to help us keep a stable sleep-wake pattern. However, significant changes in our sleep-wake schedule can interfere with our ability to sleep normally. This may be caused by what is often called “jet lag.” If, for example, a man who lives in New York flies to Los Angeles, he initially is likely to have some difficulty withhis sleep and to experience some daytime fatigue once he arrives in California. This occurs because the 3-hour time-zone change places his new desired sleep-wake schedule at odds with his “body clock” that is “stuck” inhis old time zone. This situation is shown in the second graph included in your workbook.
(Direct the patient to the graph in Chapter 2 of the workbook or show him Figure 3.2.)
The man’s body clock remains on New York time and initially lagsbehind the real-world clock time in California.
This traveler is likely to become sleepy 3 hours earlier than he wishes and to wake up 3 hours before he prefers on the initial days of his trip. Fortunately, with repeated exposure to the light-dark pattern in the new time zone, the body clock resets and allows the traveler to “get in sync” with the new time zone. However, this traveler is again likely to experience
temporary problems with his sleep and daytime fatigue when he first returns to New York.
In addition to our body clock, getting older usually leads to changes in our sleep. As we age, we tend to spend more time

awake in bed and less time in the deepest parts of sleep. Because sleep becomes more “shallow” and broken as we age, we may notice a decrease in the quality of our sleep as we grow older. Although these changes set the stage for the development of sleep problems, they do not guarantee such problems. However, because of these changes, it is probably unrealistic to expect that you will again have the type of sleep you enjoyed at a much younger age thanyou are now.
Finally, before attempting to change your sleep habits, it is important that you understand the effects of sleep loss on you. This understand- ing is important because many who have sleep problems make these problems worse by what they do to make up for lost sleep. For exam- ple, people may take daytime naps, go to bed too early, or “sleep in” following a poor night’s sleep in order to avoid or recover lost sleep.Although these habits seem logical and sensible,they all may serve to continue the sleep problems.In fact, these habits are usually the opposite of whatneeds to be done to improve sleep.
In some respects, losing sleep one night may lead to getting more or better sleep the following night. In fact,the drive to sleep gets stronger the longer one is awake before attempting to sleep again. For exam- ple, a person is much more likely to sleep for a long time after being awake for 16 hours in a row than after being awake for only 2 hours. It is important to remain awake through each day in order to build up enough sleep drive to produce a full night’s sleep.
Extended periods of sleep loss, of course, may have some bad effects as well. If people are totally deprived of a night’s sleep, they usually become very sleepy, have some trouble concentrating, and generally feel somewhat irritable. However, they typically can continue most normal daytime activities even after a night without any sleep at all. When allowed to sleep after a longer than normal period of being awake, most people will tend to sleep longer and more deeply than they typically do on a normal night. Although
people tend not to recover all of the sleep time they lost, they do typically recover the deep sleep they lost during longer than usual periods without sleep. Hence, your body’s sleep system has some ability to make up for times when you don’t get the amount of sleep you need.
37
Since you have kept a sleep log for a couple of weeks, you have proba- bly noticed that you occasionally had a relatively good night’s sleep after one or several nights of poor sleep. Such a pattern suggests that your body’s sleep system has an ability to make up for some of the sleep loss you experience over time. Although your sleep is not normal, you can take some comfort in this observation. The important point to remember is that you do not need to worry a great deal about lost sleep nor should you actively try to recover lost sleep. Needlessworry and attempts to recover lost sleep will only worsenyour sleep problem.
This information is not intended to “make light” of your sleep prob- lem. You do indeed have a sleep problem that needs to be treated.This discussion is intended to help you to understandyour problem. With this knowledge you should nowunderstand the purpose for the treatmentrecommendations I’m making. Do you have anyquestions about what you have just heard ?
Behavioral Treatment Regimen
The behavioral treatment regimen uses stimuluscontrol and sleep restric- tion strategies tostandardize the patient’s sleep-wake schedule,eliminate sleep-incompatible behaviors that occur inthe bed and bedroom, and restrict time in bed (TIB)
in an effort to force the development of an efficient,consolidated sleep pattern. The majority of behavioralrecom- mendations included in this regimen arestandard for all patients. However, the TIBprescriptions provided are based on a pretreatmentesti- mate (derived from sleep logs) of each patient’ssleep requirement. Since TIB prescriptions may varyfrom patient to patient, these prescriptions allow for
the tailoring of this regimen to fit each patient’sspecific sleep needs.
Refer the patient to the sleep improvement
guidelines in Chapter 2 of the workbook and provide
a brief justification for each behavioral rec-
ommendation included in the regimen. The workbook
provides a list of “rules” to follow and also includes
space for the patient to note his or her standard
wake-up time and suggested earliest bedtime. You
may use the following sample dialogues as you
review each sleep rule with the patient.
38
Rule 1: Select a Standard Wake-Up Time
Emphasize the importance of choosing a standard
wake-up time and sticking to it every day regardless
of how much sleep the patient actually gets on any
given night. This practice will help the patient develop
a more stable sleep pattern.
As discussed earlier in the session, changes in your sleep-wake schedule can disturb your sleep. In fact, you can create the type of sleep problem that occurs in jet lag by varying your wake-up time from day to day. If you stick to a standard wake-up time, you will soon notice that you usually will become sleepy at about the right time each evening to allow you to get the sleep you need.
Rule 2: Use the Bed Only for Sleeping
Explain to the patient why it is critical that the bed
be used only for sleeping and sexual activity.
While in bed, you should avoid doing things that you do when you are awake. Do not read, watch TV, eat, study, use the phone, or do other things that require you to be awake while you are in bed. If you frequently use your bed for activities other than sleep, you are unin- tentionally training yourself to stay awake in bed. If you avoid these activities while in bed,your bed will eventually become a place where it is easy to go to sleep and stay asleep. Sexual activity is the only exception to this rule.
Rule 3: Get Up When You Can’t Sleep
Many people linger in bed for minutes, or even hours,
when they can’t fall asleep. Lying in bed awake and
trying harder and harder to go to sleep only
increases anxiety and frustration which make the
sleeping problem worse.
Never stay in bed, either at the beginning of the night
or during the middle of the night, for extendedperiods without being asleep. Long periods of beingawake in bed usually lead to tossing and turning,
39
becoming frustrated, or worrying about not sleeping. These reactions, in turn, make it more difficult to fall asleep. Also, if you lie in bed awake for long periods, you are training yourself to be awake in bed. When sleep does not come on or return quickly, it is best to get up, go to another room, and return to bed only when you feel sleepy enough to fall asleep quickly. Generally speaking, you should get up if you find yourself awake for 20 minutes or so and you do not feel as though you are about to go to sleep.
Rule 4: Don’t Worry, Plan, etc., in Bed
Bedtime is not the time to attempt problem solving orto engage in think- ing or worrying. Engaging inthese sorts of activities only serves to keep the mindawake, making it extremely difficult to fall asleep.
Do not worry, mull over your problems, plan future events, or do other thinking while in bed. These activities are bad mental habits. If your mind seems tobe racing or you can’t seem to shut off your thoughts, get up and go to another room until you can return to bed without this thinking interrupting your sleep. If this disruptive think- ing occurs frequently, you may find it helpful to routinely set aside a time early each evening to do the thinking, problem solving, and planning you need to do. If you start this practice you probably will have fewer intrusive thoughts while you are in bed.
Rule 5: Avoid Daytime Napping
Strongly recommend to the patient that he refrain
from taking daytime naps. If the patient absolutely
must take a daytime nap, instruct him to keep it to
less than an hour and to complete it before 3:00
PM. However, the patient should do all that he can
to avoid taking naps, regardless of how tired he may
be.
You should avoid all daytime napping. Sleeping during
the day par- tially satisfies your sleep needs and, thus, will weaken your sleep drive at night.
40
Rule 6: Go to Bed When You Are Sleepy, but Not Before the Time Suggested
Advise the patient to attempt sleep only when he is feeling sleepy.
In general, you should go to bed when you feel sleepy. However, you should not go to bed so early that you find yourself spending far more time in bed each nightthan you need for sleep. Spending too much time in bed results in a very broken night’s sleep. If you spend too much time in bed, you may actually make your sleep problem worse.I will help you to decide the amount of time to spend in bed and what times you should go to bed at night and get out of bed in the morning.
Determining Time in Bed Prescriptions
As briefly discussed in Chapter 2, you will use the
patient’s pretreatment sleep logs to determine how
much time he or she should stay in bed. First,
calculate the average total sleep time (ATST)
displayed by the patient as shown on his completed
sleep logs. Then, use the following formula to make
a recommendation of how long the patient should
remain in bed each night.
Time in Bed (TIB) = Average Total Sleep Time (ATST) + 30 minutes
Remember to add 30 minutes, which accounts for thetime it takes to fall
asleep as well as a few normal, brief nocturnalarousals.
To illustrate how a TIB prescription is determined,consider the sleep log data shown in Figure 3.3. Thislog presents 6 days worth of data as well ascalculations of the average total sleep time (ATST) andaverage time in bed across this 6-day period. Note inthis example the patient slept 400 minutes per night,
on average, but had an average time in bed of 540
minutes (i.e., 9 hours) per night. The ATST falls
between 61⁄2 and 7 hours and, as such, does not seem
at all abnormal. However, there is a markeddiscrepancy between the average time slept and theaverage time in bed. Given the data shown, the TIBprescription derived using the above formula wouldbe 430 minutes, or 7 hours and 10 minutes. Hence,that TIB prescription
41
would be used as the initial time allotment for thenocturnal sleep period. Of course, patient preferencesshould be considered when establishing the initial TIBallotment, and it is perfectly acceptable to round theTIB pre- scription identified in this example to either
7 hours or 71⁄4 hours if such rounding helps with the
patient’s sleep scheduling. It should be noted that inpractice it is preferable to derive the initial TIBprescription from sleep log data collected for 2 ormore weeks so that a more stable estimate of ATSTcan be made.
Once the initial TIB prescription is determined, it is
important to help the patient choose a standard
wake-up time and earliest bedtime so that the
prescription can be followed. In doing so, it is
important to have the patient consider both “ends”
of the night. A patient may ini- tially decide that
7:00 AM is a desirable wake-up time. That choice
may seem reasonable to the patient with the TIB
prescription derived in the preceding example.
However, if the initial TIB prescription is much
shorter, say 6 hours, this wake-up time would result
in an earli- est bedtime of 1:00 AM. Upon
discovering this fact, the patient may wish to select
an earlier wake-up time so that bedtime can be
earlier during the night. Whatever wake-up and
bedtimes are chosen, it is important to involve
the patient in this decision-making process.
Adherence to the TIB prescription will usually be
best when the patient takes an active role in
selecting his own bed and wake-up times.
Managing Patients’ Expectations and Treatment Adherence
Once the treatment regimen has been explained and
an agreed upon sleep schedule has been established,
it is helpful to provide the patient some addi- tional
information about the likely course of treatment and
the importance of treatment adherence. Most
treatment-seeking insomnia patients are notably
distressed by their sleep-wake disturbances and desire
rapid relief from such symptoms. However, as is the
case with most psychological and behavioral
interventions, the current treatment produces
improvements gradually and requires consistent
treatment adherence on the patient’s part to achieve
optimal results. In our experience, most patients who
show con- sistent adherence to the behavioral
strategies described earlier show marked reductions
in their wake time during the night within the first 2 to
3 weeks

of treatment implementation. Improvements
(increases) in average sleep time at night are less
dramatic and occur much more gradually during treat-
ment. However, many patients continue to
appreciate some sleep time improvements even after
formal treatment (therapist contact) ends. Of course,
patients who do not adhere well to the treatment
recommendations may improve more slowly or not at
all. Thus, encouraging consistent treat- ment
adherence is highly important to the treatment process
and outcome overall.
You may wish to use the following sort of dialogue to
emphasize these points to the patient:
Now that we have discussed what you are to do to improve your sleep, you should understand that it is important to follow all the recom- mendations we havediscussed consistently each and every day of the week.If you are able to do that, you likely will start to see some improvements in your sleep within the next 2 to 3 weeks. You are likely to notice first that the time you take to get to sleep and the amount of time you spend awake during the night will decrease significantly. Although you may not see large changes in the amount of time you sleep each night during this time period, your sleep should start to become more solid and restorative. However, if you do not follow the recommendations we have discussed consistently, your progress will likely be much slower oryou may not see any significant changes in your sleep.Thus, it is important that you follow the treat-ment recommendations we discussed consistently so thatyou obtain the types of results you are seeking.
As you begin this treatment at home, it is also importantfor you to understand that the sleep schedule we agreed upon for you today may leave you feeling a littlesleepy in the daytime, particularly during the first week as you get adjusted to this new schedule. If you notice an increase in sleepiness, avoid activities wherein your sleepiness might be dangerous to you such as driving long distances or operating hazardous machinery. If you continue to feel sleepy in the daytime beyond the first
week, that usually means we have limited your time in bed at night too much and you would benefit by increasing this time somewhat. If this is the case when you return for your next session, we will review your sleep logs and make the needed adjustments in your nightly sleep schedule to
44
address this problem. Moreover, we can continue to make such adjust- ments from session to session until we arrive at the schedule that works best for you. It is important that you follow the treatment recommenda- tions consistently from week to week and chart your progress on the sleep logs in your workbook. This will allow us to assess your progress and determine what, if any, changes in your schedule might be needed.
Managing Patients Unable to Attend Routine Follow-Up Sessions
It is desirable to provide patients one or more returnvisits to encourage and reinforce treatment
adherence, resolve difficulties they are having withtreatment enactment, and assist them in making TIBadjustments. However, we encounter some patientswho live a great distance from our clinic or for otherreasons are not able to return for follow-up ses-sions. Both our clinical experiences and our recent
research findings (Edinger et al., 2007) suggest thatsome patients are able to achieve significant sleepimprovements over time following only one sessionwherein the information covered in this chapter ispresented. However, in such cases, it is useful to givethe patient instructions that will enable him to makeneeded TIB alterations to establish an optimalsleep wake pattern. For such individuals, you mayuse the following sample dialogue:
You should try this sleep-wake schedule for at least two weeks and determine how well you sleep at night and how tired or alert you feel in the daytime. If you sleep well most nights and are as alert as you would like to be in the daytime, then you probably should make no changes in your time in bed each night. If, however, youfind you are sleeping well at night, but you feel tired most days, you should try increasing your time in bed atnight by 15 minutes. If, for example, you begin with 7 hours in bed per night the first week and find that you are tired in the daytime despite sleeping soundly at night, you should try spending 7 hours and 15 minutes
in bed each night during the sec- ond week. If, with this amount of time in bed, you continue to sleep soundly atnight but still feel tired in the daytime, you can add another 15 minutes to the time in bed during the third week and so on.
45
However, when you notice an increase in the amount oftime you are awake in bed each night, you will know that you are spending too much time in bed at night. If this occurs, you should decrease your time in bed by 15 minutes per week until you find the amount of time that enables you to sleep soundly through the night andfeel reasonably alert in the daytime. You should also decrease your time in bed after the first 2 weeks if the initial amount of time in bed we choose together today does not reduce your time awake in bed each night.
To help you make decisions about changing your timein bed, it may be helpful to consider some simple guidelines. If you routinely take more than 30 minutes to fall asleep or you are routinely awake for more than 30 minutes during the night, you probably should reduce the amount of time you spend in bed each night. You also should consider decreasing your time in bed if you find that you routinely awaken more than 30 minutes before you plan to. Of course, the key word here is “routinely.” Occasional nights during which you have a somewhat delayed start to your sleep or you have more wakefulness than usual once you get to sleep, should not be viewed as reasons for changing your sleep schedule. Only when such occurrences are frequent or routine should you try a somewhat shorter time in bed. In the end, the best guideline to use is how you feel each day. If you are satisfied with how you generally feel in the daytime, you can assume that the sleep you are obtaining at night is sufficient.
Providing Basic Sleep Hygiene Education
In addition to providing the sleep improvement
guidelines mentioned earlier, the patient should be
given some standard sleep hygiene education and
instructions to encourage lifestyle practices that
promote sleep qual- ity and daytime alertness. These
recommendations are a common com- ponent of
behavioral insomnia therapy, have good “face
validity,” and are easily understood by the majority of
patients. They are also included in Chapter 2 of the
workbook. To facilitate the patient’s acceptance of
and
46
adherence to these recommendations, the followingrationale should first
be provided to the patient.
The sorts of daytime activities in which you engage, the foods and beverages you consume, and the surroundings in which you sleep may all influence how well you sleep at night and how you feel in the daytime. Thus, in addition to making the specific changes to your sleep habits we have discussed, you also may benefit from making some changes to your lifestyle and bedroom to promote a more normal sleep-wake pattern.
Once this general rationale has been presented, thepatient should be given the specific sleep hygienerecommendations described in the follow- inginstructions:
Recommendation 1: Limit your use of caffeinated foods and beverages such as coffee, tea, soft drinks with added caffeine, or chocolates.Caffeine is a stimulant that may make it harder for youto sleep well at night. You should also know that caffeine stays in your system for several hours after you consume it. Therefore, we recommend that you limit your caffeine to the equivalent of no more than three cups of coffee per day and that you not consume caffeine in the late afternoon or evening hours.
Recommendation 2: Limit your use of alcohol. Alcoholic beverages may make you drowsy and fall asleep more easily. However, alcohol also usu- ally causes sleep to be much more broken and far less refreshing than normal. Therefore, we recommend against using much alcohol in the evening or using alcohol as a sleep aid.
Recommendation 3: Try some regular moderate exercise such as walk- ing, swimming, or bike riding. Generally, such exercise performed in the late afternoon or early evening leads to deeper sleep at night. Also improving your fitness level, no matter when you choose to exercise, will likely improve the quality of your sleep. However, avoid exercise right before bedtime because itmay make it harder to get to sleep quickly.
Recommendation 4: Try a light bedtime snack that includes such items as cheese, milk, or peanut butter. These foods contain chemicals that your body uses to produce sleep. As a result, this type of bedtime snack may actually bring on drowsiness.
47
Recommendation 5: Make sure that your bedroom is quiet and dark. Noise and even dim light may interrupt or shorten your sleep. You can block out unwanted noise by wearing earplugs, running a fan, or using a so-called “white noise” machine that is specifically designed to screen sleep-disruptive noise. Also, if possible, eliminate the use of night-lights and consider using dark shades in your bedroom so that unwanted light does not awaken you too early in the morning.
Recommendation 6: Make sure the temperature in your bedroom is comfortable. Generally speaking, temperatures much above 75 degrees Fahrenheit cause unwanted wake-ups from sleep. Thus, during hotweather, we suggest you use an air conditioner to control the tempera- ture in your bedroom.
Before closing the session and assigning homework,
review the patient’s expectations for treatment and
encourage consistent treatment adherence. Also ask
the patient if he has any questions about today’s
session.

Review Homework and Treatment Adherence
Specifically targeting cognitive change may beimportant for increased adherence to behavioralrecommendations, as well as eliminating sleep-interfering thoughts. As a result, Session 2 is
devoted to restructuring
49
cognitions and outlining strategies for mental
overactivity. You may use the following sample
dialogue to begin the session:
Today we will be focusing on the role of thoughts in insomnia, but before we do, I’d like to check in on your experience with some of the recommendations from last session.
Review the patient’s completed sleep logs and check
in on the recom- mendations by asking how each one
went. Be sure to praise all instances of adherence. In
areas of non-adherence, try to frame it positively:
I can see that you had some trouble getting out of bed in the morning, but I also notice that you were able to do this on two of the mornings. That’s great. Let’s return to this issue at the end of this session and see ifwe can figure out a way to increase this to 7 days a week.
Cognitive Rationale for Patient
Begin a discussion about the role of cognitions in
the maintenance of insomnia. You may use the
following sample dialogue:
Last week we focused on changing behaviors that had negative effects on sleep. Today, we will discuss the role of your thoughts in insomnia and give you strategies to help with any problems you may be having in this regard. Specifically, we will focus on how thoughts and beliefs can cause insomnia or at least make it worse. What role do thoughts play in insomnia? Some people don’t even consider that how we think and how we feel can have a huge impact on how we sleep. It turns out that what and how we think affects how we sleep, how we feel, and how we deal with periods of sleep loss. Lots of research and con- versations with insomnia patients have led us to conclude that there is a particular way of thinking associated with insomnia. We call it the “Insomnia Brain” because most people tell us that this way of think- ing is not typical of how they normally think, but
since they havehad insomnia, their type of thinking has changed and the way they view sleep has changed too. The Insomnia Brain tends to be very “noisy” and very focused on the effects of not sleeping. Let’s take a few minutes to examine the Insomnia Brain and we’ll offer some strategies for managing this unhelpful state of mind.
50
Negative thoughts in the insomnia brain spread like wildfire. All the thoughts are negative and they are usually related in some way.Positive thoughts don’t make it in. Most people with insomnia tell us, “I don’t understand it, I am not usually a worrier, but once I get into bed I think about the weirdest things and I have no control.” This is the Insomnia Brain—and it can seem unrelenting.
Do you have difficulty shutting your mind off at night? The problem is that we cannot sleep when our brain is alert. Moreover, the more this happens in your bed on a nightly basis, the more likely it is to continue to happen. This is because it becomes an unintentional and unwanted habit. The good news is that all habits can be broken if you have a good strategy.
Do you tend to get upset about not sleeping or worry about whether or not you will be able to manage during the day? Many people with insomnia will say, “I wasn’t worried at all today but as soon as my head hit the pillow, it was like a switch went off.” Does this ever hap- pen to you? It means that your bed has become a signal for worryand upset. There are ways to change this signal.
Remember your homework from last session? You were to leave the room when you were unable to sleep. One of the most effective strategies for quietingan active mind is to leave the bedroom when your mind starts to take over. This will break the habit. It may take several attempts at first but your brain will eventually get the pic- ture that your bed is not the place for it to be active. This practice may have otherbenefits too. Taking the Insomnia Brain out of bed results in becoming more clearheaded and being better able to switch off your troublesome thinking. Most people tell us thatthe worry they could not switch off in the bedroom became a non- worry in the living room. So, do yourself a favor and get out of the domain of the Insomnia Brain temporarily. You can return to the bed when you are no longer worrying or problem solving. Some people are concerned that getting out of bed will limit their oppor- tunity for sleep, but the
chance of you sleeping while your brain is active is limited. Getting this type of mental activity under control by spending a few minutes out of bed will increase your chancesof being able to sleep.
51
Assess if the patient has any questions and whetherany of this discus- sion seems to be personallyapplicable. Reinforce the patient’s identificationwith the problem. For example, if the patient says,“I definitely worry in bed about every little thing.” Besure to say, “Okay, then it’s going to be important forus to focus on this and for you to complete someadditional homework over the next 2 weeks.”
Constructive Worry
Many people with insomnia complain of “unfinishedbusiness” follow- ing them into the bedroom andcreating arousal/distress in bed. Indeed, problemsolving in the presleep period has been implicatedas one of the strongest predictors of difficulties
falling asleep (Wicklow & Espie, 2000). Espie andLindsay (1987) were among the first to report positiveresults for an early evening procedure that targetedpresleep worry. Similarly, Carney and Waters (2006)demonstrated that a single night of using an earlyevening procedure called Constructive Worryresults in decreased presleep arousal. As a result,providing a tool to manage nocturnal worry is often
helpful. If nighttime worry is a significant issue, it isimportant to pair this procedure with stimuluscontrol (i.e., the instruction to leave the bedroomwhen problem solv- ing or worrying) and other stressmanagement techniques such as relax- ation and/ortime management techniques. Introduce the exercisewith a rationale such as the following:
While most people find that getting out of the bed is enough to address their nighttime worry problem, some continue to worry. Some bedtime worries are a result of keeping so busy during the day that no time is available to deal with the worries. Sleep is the first opportunity that is quiet enough for your brain to try to complete its unfinished business. Does this sound like it applies to you?
The Constructive Worry Worksheet is taken from
Carney & Waters (2006) and copies for the patient’suse are provided in the workbook. A sample,completed worksheet is shown in Figure 4.1. Thefollowing instructions also appear in the workbookand should be used as a guide when completing theworksheet with the patient in session.
52
1. Write down the problems facing you that have
the greatest chances of keeping you awake at
bedtime, and list them in the “Concerns”
column.
2. Then, for each problem you list, think of the next step you might take to help fix it. Write it down inthe “Solutions” column. This need not be the finalsolution to the problem, since most prob- lems have to be solved by taking a series of steps anyway, and you will be doing this problem-solving task again tomorrow night and the night after until you finally get to the best solution.
If you know how to fix the problem completely, then writethat down.
If you decide that this is not really a big
problem, and you will just deal with it when the time comes, then write that down.
If you decide that you simply do not know
what to do about it, and need to ask someone to help you, write that down.
If you decide that it is a problem, but there
seems to be no good solution at all, and that you will just have to live with it, write that down, with a note to yourself that maybe some- time soon you or someone you know will give you a clue that will lead you to a solution.
3. Repeat this for any other concerns you may have.
4. Fold the Constructive Worry Worksheet in half
and place it on the nightstand next to your bed
and forget about it until bedtime.
5. At bedtime, if you begin to worry, actually tell
yourself that you have dealt with your problems
already in the best way you know how, and when
you were at your problem-solving best. Remind
yourself that you will be working on them again
tomorrow evening and that nothing you can do
while you are so tired can help you any more
than what you have already done; more effort
will only make matters worse.

if she foresees any barriers to completing this

patient to reduce such barriers to adherence.
Thought Records
Cognitive restructuring is most often associated withthe seminal text Cognitive Therapy of Depression byAaron Beck and colleagues (Beck, Rush, Shaw, &Emery, 1979). Beck et al. wrote about fears of becom-ing ill as a result of insomnia and the discrepancybetween objective and subjective sleep timeestimation in people with Major Depression.These observations are common features of peoplewith insomnia irrespective of whether they haveMajor Depressive Disorder. Beck’s early writingswere applied to insomnia by Morin (1993), whodeveloped a cognitive therapy component forinsomnia.
54
Morin suggested the use of the Thought Record torestructure some unhelpful or inflexible thoughtsand beliefs about insomnia (Morin, 1993). In linewith these works, we have found the followinginstruc- tions to be useful.
In addition to nighttime worry, sometimes we have thoughts or beliefs about sleep that can actually make sleep worse. Most beliefs about sleep boil down to a fear about whether we will be able to cope with the insomnia. It is common for people with insomnia to worry about whether they will lose control over their abilities to sleep, whether they will become sick as a result of the insomnia, and even whether they may “gocrazy” if their insomnia persists. These worries can be very frightening, so it is often helpful to take a more critical look at the types of beliefs that lead to such distress.
The Thought Record is a very simple tool, yet we find that it is a very powerful instrument. It’s powerful because it curbs the Insomnia Brain’s tendency to be negative and consider only the worst case scenarios ofsleep loss. Balanced thoughts also challenge those beliefs that generate anxiety. Lastly, we find that this tool helps people see that they are not powerless; their efforts toward changing their sleep habits produce improvements in their sleep and in their daytime fatigue and mood.
It is important to complete a Thought Record insession so that the patient understands it wellenough to complete it between sessions. A sample,completed record is shown in Figure 4.2. A samplefor the patient to use as a model, as well as blankcopies for the patient to fill out, is also included inthe workbook. You may use the following sug- gesteddialogue to help the patient complete a blankThought Record during the session.
Let’s walk through an example of a Thought Record to help with troubling thoughts or beliefs about sleep. Think of a time, perhaps even last night when you had strong feelings or upsetting thoughts related to your insomnia. What were you doing or where were you
when you had these feelings or thoughts? Write them down in the Situation column. What kind of mood or feelings were you exper- iencing? Write down feelings in the Mood column. What are you thinking or what were you thinking when you began to feel this way?
55
Are you concerned about how you will deal with another day with this insomnia? Are you predicting thatyou’ll never sleep? Write these down in the Thoughts column. Even if some of your thoughts seem to be untrue or silly, it is important to write them down. There are no wrong thoughts to write down.
The next step is to look at why this thought may seem true. What’s the evidence for this thought? Write this down in the Evidence for the Thought column. Most people can remember a time when they had difficulty dealing with their insomnia. The Insomnia Brain remem- bers this as “evidence” that you can’t deal with insomnia. But this is probably not the whole story.
It is important to look more critically at these beliefs, and one way to do this is to think about whether this thought is true 100% of the time. For example, we may focus on the one instance in which we performed poorly at work and discount the thousands of times we have performed fine even though it was difficult. Or weoverlook that there are small things that don’t support the thought. For example, we may forget that there have been times when we have felt good after a poor night’s sleep; or when we felt poorly after a good night’s sleep; or we jump to conclusions or focus on theworst possible outcome. Write all this evidence down inthe Evidence against the Thought column. Examining the evidence against the belief forces the Insomnia Brain to focus on thoughts that are less anxiety-provoking or less frustrating.
The last step in this process is to consider both the evidence for and against the belief and think of a thought that lies somewhere in the middle. This thought should consider that there may be some part of the evidence for the belief that may be true, but it should take into consideration that there is plenty of evidence against the belief. For example, a balanced alternative to the thought, “I’m never going to make itthrough tomorrow” is: “I sometimes feel groggy at work after a poor night, but not always, and I always seem to cope pretty well with it.” Write this new thought down in the Adaptive/Coping Statement column. Most people tend to feel a little better after
com- pleting this exercise. Try it over the next week or two until our next visit and we’ll review it then.

In reviewing the Thought Record with the patient,
it is important to indicate that the patient’s
thoughts and feelings are valid. It is also important
to acknowledge that you know it may seem difficult
to the patient to change her thoughts given how
automatic they are. Ask the patient to explore
whether there may be costs to having such strong
conviction in these thoughts and whether these
thoughts may be adding to the problem (i.e.,
emotional reasoning). This may be done by
highlighting what Greenberger and Padesky (1995)
call the Thought-Mood connection. For example, if
the patient is having the thought, “I’m never going
to get to sleep,” ask them how they feel when they
think they are never going to get to sleep. Hopeful or
hope- less? Is it setting up a self-fulfilling prophecy?
It is also important to recognize that patients may
present many types of “cognitive errors” (Beck et
al., 1979) during both the in-session exercise and
when using the Thought Record at home. It is
very important to review such “errors” when
patients present them, although it is not helpful to
label them as “errors.” It is more helpful to explore
them without labeling, and instead talk about
particular “thinking styles” or “thought pat- terns”
that occur when people’s moods are disturbed. The
following are the most common unhelpful “thinking
styles” or “thought patterns” we encounter in our
insomnia patients when using Thought Records with
them.
Misattribution: people with insomnia tend to
attribute any cognitive troubles or negative mood
to poor sleep, and they discount several other
factors. For example, it is normal to experience some
grogginess for the first 30–60 minutes upon
awakening. It is called sleep inertia. Many people
with insomnia who experience this on awakening
believe that this is evidence that they had a poor
night’s sleep and pre- dict they consequently will
have a bad day. Similarly, it is normal to experience
an increase in sleepiness and a decline in mental and
emo- tional functioning in the early afternoon. This
is a normal phenome- non called the “post-lunch
dip.” It corresponds to a “dip” in one’s body
temperature after lunch. This is often the time when
people with insomnia nap, cancel appointments, or
leave work. They believe that this dip is evidence
that they cannot function. Providing education on
this phenomenon and focusing on coping strategies
to ride out sleep inertia or the circadian dip (e.g.,
exposure to fresh air, activity, coping
58
statements such as “this is just temporary”) will be
helpful for patients.
Emotional Reasoning: Some patients focus on their
feelings as facts. For example, they believe that the
presence of anxious feelings is evidence that they
will not sleep. Such a belief will lead to further
anxiety when sleep does not come quickly.
All-or-none thinking: “I didn’t sleep last night.” Explorewith your patient the cost of thinking “I don’t sleep.”Is it increased anxiety? It is often helpful to train
patients to “find the missing sleep” in their sleep logsand to “catch themselves asleep.” Did they miss partsof the plot of the television program they werewatching? When patients report that they have beenawake “all night long,” ask what they were doing. Itis highly unlikely that they were lying motionless in
their bed for 8 hours without sleeping. Some patientshave difficulty with sleep perception because their brainactivity is “noisier” than most people when they sleep(Krystal et al., 2002). Some people need thereassurance that their body is “sleeping” from anobjective standpoint and is thus restoring andprotecting itself; however, it feels like very poor or “no”sleep because of the mental activity.
Self-fulfilling prophecy: People with insomnia often
predict that their day will be terrible because they had
poor sleep—is it possible that they approach their day
in a way that ensures this will be true? It has been
said, “Whether you think you can or you cannot, you
are right either way.” There is tremendous power in
the mind’s ability to create a reality consistent with its
beliefs. As a result, it is important to give the patient
the option of creating a self-efficacious, coping reality
instead of a bleak one.
Catastrophizing: “I’m going to go crazy.” The fear ofserious mental or physical illness as a consequenceof the insomnia is a common fear for insomnia
sufferers. It is important to follow their fears totheir most catastrophic conclusion to understand
someone’s fear of insom- nia. This has beendescribed elsewhere (Burns, 1980) as the “down-ward arrow” method, which is illustrated in thefollowing case vignette. In this dialogue, Trepresents the therapist and P represents thepatient.

Case Vignette
T: You told me that you start to worry as soon as you
notice that you have been in bed an hour without
sleeping. Can you tell me a little about the thoughts
or images you experience when you notice the clock?
P: I think, “Oh God, I have a big day at work tomorrow.
If I don’t get to sleep, I’ll be useless at work.”
T: You’re worried you’ll be useless at work, what would that mean?
P: I could get into trouble.
T: And then what? What would be the worst case scenario?
P: Well, I’d get fired, I guess. Well I probably wouldn’t
get fired, but that’s what I am worried about.
T: Well let’s stay with this fear for a moment. Can you get a picture of
getting fired because of your insomnia?
P: Yes, I’ve pictured it many times. My boss is telling
me my work has been slipping and I look like I’m
sleepwalking, so he’s going to let me go.
T: And then what?
P: Well, I could never do well on a job interview feeling
the way I do, so I don’t think I could get another
job. Well, maybe I could . . .
T: Let’s stay with this a moment if you can. So you might not be able to
find another job?
P: Well, yeah, and then I can’t pay my bills and then I’m homeless.
T: So you’re homeless and then what?
P: Well, that’s it. I’m homeless. I can’t take care of
myself and I’ll be like that forever I guess.
T: Wow, it sounds like there’s a lot riding on whether
you get to sleep tonight. Maybe by looking at this
chain of events operating below the surface we can
understand why you become so anxious when you
can’t sleep. Losing an hour of sleep triggers a chain
of thoughts that leads to you becoming homeless
forever. No wonder you are so upset when you get
into bed. Do you think we could take a closer look at
this belief?
60
Exploring this fear and empathizing that it’s no
wonder the patient is worried about sleep when the
stakes seem so high (i.e., it feels as though they may
become ill), is a good starting point for modification
of this belief. Many patients are surprised that they
have such catastrophic beliefs lurking beneath the
surface.
Mind reading: Some people with insomnia believe thatothers are “notic- ing” their poor performance. Theymay worry about this out of a fear of negativeevaluation from others. This belief is often untruebecause most people with insomnia function quitewell. What tends to be different after a poor night’s
sleep is the amount of extra effort required to do reg-ular tasks (Espie and Lindsay, 1987). Even if thefollowing belief is true, “People notice that I amincompetent at work because of my insomnia,”
exploring whether it is true 100% of the time andexploring the conse- quences of holding such a beliefcan be helpful. For example, if there are fears ofnegative evaluation, believing that this is true willresult in increased anxiety in performancesituations. We know that anxiety can interfere withperformance; thus, fears of poor performance willresult in poorer performance. It is helpful to explorewhether this formulation may apply to the patient andwhether it would be useful to modify this belief.
Overgeneralization: Overfocusing on a single instance(i.e., I had trou- ble completing my crossword puzzlethis morning . . .) as proof that their beliefs are true(“ . . . so, I am mentally useless at work today.”)Encourage patients to see the range of evidencebecause people with insomnia tend to copeextraordinarily well 90% of the time.
Discounting the positive/Focusing exclusively on the
negatives: There are often hundreds of instances of
coping and good functioning within the day that are
discounted in lieu of one instance wherein
functioning was lower (e.g., the patient forgets about
one appointment). There are likely times when the
patient may have had a poor night and still man-
aged to have a good day. Similarly, there are often
instances in which the patient may have voluntarily
had a night with no sleep (e.g., stayed out late with
friends) and had a good day afterwards. Lastly, many
patients discount that there are days in which they
had a good night’s sleep and did not have a good day.
Explore all of these scenarios with your patient.
Although we have focused on cognitive “errors” is it
important to keep in mind that it is the “adaptiveness”
of the beliefs that is important to
61
explore, not whether or not they are “true.” In other
words, it is impor- tant to explore the consequences
of the belief (i.e., does the belief increase anxiety?),
because some beliefs are true to some extent. When
beliefs become so rigid that they cause emotional
arousal, it may be important to modify them. The
goal is to give patients choices when their thoughts
are activated. We want them to get into the habit of
forc- ing themselves to consider alternative thoughts
in addition to their neg- ative thoughts. If it becomes
a habit, they will have a choice. If their current
pattern continues, it allows the Insomnia Brain to
focus only on confirmatory evidence (i.e., that they
can’t cope, things are hopeless, etc.). Forcing the
Insomnia Brain to consider other evidence will be
uncomfortable at first, but soon it will become a
habit and these thoughts will lose their negative
potency.
In working through the Thought Record in session, youmay note some patients have difficulties completingone or more of the columns. Some people mistakemoods and thoughts, some people think that they haveno thoughts (i.e., their mind is blank), some havetrouble generating evidence, and others have difficultyintegrating the evidence into a bal- anced thought.Greenberger and Padesky (1995) have many suggestionsfor helping patients who have these difficulties. TheSituation column can be completed by asking thepatient: “Who was with you when you started feelingbad? What were you doing? Where were you? When did ithappen?” For example, a patient may tell you about asituation in which she started worrying about herability to sleep that night. When probed with thesequestions, the patient can usually fill in the blanks,and tell you she was in the living room with her spousewatching television after dinner. Moods are bestdescribed using one word. When patients needmultiple words to describe a mood, they are mostlikely describing a thought instead.
The Thoughts column can be challenging for some
patients. You want to elicit what was going through
the patient’s mind during the upset- ting situation.
Ask the patient to focus on the emotions as clues to
what she was thinking. For example, if the mood is
anxious, ask the patient if she can identify what
caused the anxiety. It is then often helpful to have
the patient consider the most extreme scenario by
asking a series of questions: “You said you were
anxious about waking up in the morn- ing. What is
the worst possible thing about waking up in the
morning?
62
What is the worst case scenario?” Also, ask thepatient if this situation reminds her of other similarsituations. This usually results in generat- ing somethoughts or images. If the patient had difficultynaming a mood and was instead listing “thoughts,”be sure to make note of these thoughts so you canpresent them for inclusion in the Thoughts columnlater. You can give patients the following hint to helpidentify thoughts in the future: “The next time youare experiencing a strong emotion, ask yourself tonotice what is going through your mind.”
Most automatic thoughts in insomnia patients relateto a fear that some- thing is very wrong with themand that they are helpless to change it. Elicitingcatastrophic statements from the patient’s thoughts ishelpful to get at the core beliefs. For example, apatient is afraid of setting the alarm and reports thethought, “If I set the alarm then I know I will onlyhave 7 hours to sleep, and every hour that goes by I’llbe thinking that I have to get up.” Ask the patientwhy having only 6 hours, or 5 hours, of sleep isdistressing, and what is the worst case scenarioimagined for that situ- ation. Then, take the worstcase scenario (e.g., getting fired from a job becausesleep loss is causing unacceptably poor workperformance) and reflect it back to the patient suchas: “Gosh, if you think you are going to get firedbecause of your insomnia, it sounds as though therereally is so much riding on you getting to sleep eachnight.” This will either elicit more cata- strophicstatements or the patient may engage in reportingevidence against the thought because thecatastrophic nature of the thought is dis- concerting.When generating automatic thoughts, it is usuallyimportant to generate several thoughts and not stopat one. One technique for facil- itating the recordingof multiple thoughts is to lead the patient to thenext thought by repeating how she was thinking andfeeling and ask what happened next: “So you werefeeling anxious and thinking, ‘I’m going to have to callin sick.’ And then what?”
Most patients do not have difficulty generatingevidence for the thought in the Evidence for theThought column, because the thoughts are seen asvery compelling. One common problem is thetendency to rush through the evidence and say,“Yeah, but I know that’s not really true.” It’simportant to spend some time on the evidence for
the belief and reflect that the patient isn’t “crazy” sothere must be a good reason to have this belief.Exploring the kernel of truth in the evidence for thebelief is really important.
63
Generating items for the Evidence against theThought column can be challenging for somepatients. Keep track in earlier sessions of anyevidence the patient cited that is contrary to thebelief. For example, the patient may talk about ahorrible day in which nothing catastrophichappened. Or the most feared situation (e.g., “goingcrazy”) has not occurred despite the fact that thepatient had suffered from years of insomnia.
Focusing on evidence of the patient’s effective copingcan also help here. The following questions may alsohelp:
“If someone you cared about thought their insomnia
problem was hopeless, would you tell them, ‘Yeah, you’re right, it is hopeless.’ Why not? Why wouldn’t this be helpful ?”
“Are you discounting your strong coping skills? I’m
impressed by the tremendous coping resources you seem to have.”
“Has there been a time in the past when you had very
little sleep and functioned well ?”
“Have there been times in the past when you had lots
of sleep and felt poorly during the day?”
“Have there been situations when this thought is not
true 100% of the time? For example, you say you get headaches when you have insomnia; do you have headaches every single day?”
The “cognitive errors” discussed earlier may also
help patients with this column.
Generating an Adaptive/Coping Statement can be
difficult for patients. Some patients will focus on the
evidence for the belief and have difficulty
incorporating the evidence against the belief. Others
will want to focus exclusively on the evidence against
the thought, which is equally prob- lematic. One of
the easiest formulas to derive a coping statement is
to start with a statement from the evidence for the
belief column, and fol- low it with a “BUT,” and then
a statement from the evidence against the belief
column. For example, “I sometimes forget things at
work, BUT, sometimes I forget things even if I had a
decent night’s sleep.” Encourage the patient to
modify this statement until it seems believable and it
is something that can be remembered. Positively
reinforce even tiny improvements in mood, as this is
evidence that there has been some
64
input into the Insomnia Brain. For example, “Okay, soyou are 5% less anxious? That’s still an improvementfrom 5 minutes ago. Small victories are important in thisprocess, so good for you.” Patients will generally reportthat their mood is less negative following the exercise.If there has not been a mood improvement, seeChapter 5 for some troubleshooting tips.
After jointly completing a Thought Record, ask if the
patient has any questions and instruct her to
complete a Thought Record whenever a negative
sleep-related shift in thoughts or mood occurs. If
patients initially have difficulty noticing this shift, get
them to practice by retro- spectively completing one
Thought Record per day. The practice of recording
the situation, moods, and thoughts components of
the Thought Record will typically improve their
ability to notice shifts in their mood or thinking, or
at least recognize patterns in the types of sit- uations
that generally produce sleep-related thoughts or
feelings. Remember, the goal in therapy is for the
therapist to be replaced by the patient’s mastery of
this new skill (i.e., the Thought Record). To gain
mastery over the technique requires successful in-
session exploration of records, as well as much
between-session practice. Given the brevity of this
treatment, there will likely be one or two
opportunities to go through a Thought Record in-
session. Be sure to make the most of these few
opportunities and troubleshoot any problems with the
technique.
Dealing With Resistance
The best way to manage resistance is to reduce the
likelihood that it will occur. It is important for the
therapist not to directly challenge beliefs; rather,
encourage the patient to scrutinize the belief.
Patients who are directly challenged on a belief may
be more likely to respond with reactance (Brehm &
Cohen, 1962). That is, they are more like- ly to
argue on behalf of the unhelpful belief. Collective
empiricism (Beck et al., 1979) is the cornerstone of
Cognitive Therapy. Effective therapists help
patients to explore the utility of holding the belief
so strongly. Socratic questioning is often helpful in
this regard. Socratic questioning is achieved by
leading a patient through a series of questions
designed to create uncertainty about the unhelpful
belief. It is important to be efficient in your
questioning because a
65
long, unfocused series of questions can make the
session feel like an interview. This is best done by
having a clear idea of the conclusion you wish for
the patient to reach. In the example that follows,
the therapist wants the patient to consider stress as
an additional expla- nation for her headaches and
to focus on ways to manage the headaches.
Case Vignette
T: So, you’re afraid that you are going to become seriously ill because of
your insomnia?
P: Definitely. I feel horrible, and I’m starting to get thesereally bad
headaches.
T: And the headaches are evidence that you may be getting sick?
P: Yeah. My doctor ran some tests and said it was
stress but I’m sure there is something else wrong.
T: That must be scary to think that you have an
undetected illness. I’m relieved that the tests
haven’t revealed a serious illness. Wouldn’t it be
good news if it were stress related?
P: I guess. I don’t see how it could be stress.
T: How much do you know about the kind of body changes stress
produces?
P: Not much. I guess it makes you tense. Are the headaches because
of the tension?
T: I’m not sure. Do you think they
could be? P: I don’t know. I can’t
believe it’s stress.
T: Isn’t having insomnia stressful?
P: It definitely is.
T: Maybe we could spend a few minutes talking about stress symptoms
and how to manage them?
66
One final issue that may surface in therapy is when
thoughts are related to believing that CBT will not
work. It is important to explore resistance to therapy
in a nonjudgmental, curious way. Many patients have
tried several treatments and are understandably
frustrated and scared that they are losing control
over their ability to sleep. Highlighting the ambiva-
lence is often important in this regard.
Case Vignette
P: I have insomnia because of my Chronic Fatigue Syndrome, not
because I have bad sleep habits.
T: You may be right. But if we could improve your sleep, wouldn’t you like to try?
P: I’ve tried a dozen pills and nothing works. I’ll never sleep better until they find a cure for Chronic FatigueSyndrome.
T: It must be frustrating to have tried so many
treatments in the past and nothing works. To try so
many medications in the past makes me think that
you would really like to improve your sleep. Would
you like to try a new approach over the next couple
of weeks? Would it hurt to try something that may
help you sleep better?
P: Well yeah, it may hurt. If something else doesn’t
work, things will seem hopeless.
T: Sounds like you’ve been feeling hopeless about
your sleep. Is this something worth talking about?
This brief interchange highlights how a patient’s initial resistance to
CBT might be addressed.
Homework
✎ Instruct the patient to continue recording her sleep
habits using
the sleep logs provided in the workbook
67
✎ Ask the patient to fill out the Constructive Worry
Worksheet in the early evenings and bringcompleted forms to the follow-up session, ifapplicable
✎ Ask patients to also complete Thought Records
whenever they notice a sleep-related bothersome thought or feeling (e.g., usually at least one daily), and to bring these records to the follow-up session, if applicable
68
Chapter 5 Follow-Up S essions
Once patients are provided the behavioral andcognitive strategies discussed in the previous twochapters, they usually benefit from one or morefollow-up sessions to (1) assist them in makingneeded adjust- ments in their TIB prescriptions, (2)encourage and reinforce their adherence totreatment recommendations, and (3) “troubleshoot”the problems they may be having with thebehavioral or cognitive tech- niques they have beentaught.
There are no new materials needed during these
follow-up sessions. The therapist should be guided by
the patient’s self-report of progress as well as by a
review of completed sleep logs, Constructive Worry
Worksheets, and Thought Records. You should
review all of these “homework” materials that the
patient brings to the session and provide guidance as
needed using the information that follows.
Adjusting Time in Bed Recommendations
The method for making adjustments in TIBprescriptions was discussed in Chapter 3. Reviewthe patient’s completed sleep logs each week anddetermine his average sleep efficiency during theweek prior to the current session. Sleep efficiencyis calculated by dividing the patient’s average totalsleep time (ATST) over the time period since theprevious session by the average time spent in bed(ATIB) and then multiplying the result by 100%(Sleep Efficiency = (ATST/ATIB) X 100%). If
the patient’s sleep efficiency is > 85% and thepatient has noted daytime sleepiness with thecurrent TIB prescription, suggest a 15-minuteincrease in TIB. Suggest a 15-minute decrease inTIB if the patient’s sleep efficiency is < 80%. Ifthe
69
patient is sleeping soundly most nights and feeling
alert in the daytime, then no TIB adjustment is
needed.
At times patients will develop problems with
excessive sleepiness as a result of restricting their
TIB to the initially prescribed amount. This problem
may occur in some insomnia patients who markedly
underes- timate their sleep time on their pre-therapy
sleep logs. Other patients may experience increased
anxiety when limits are placed on the times they
allot for sleep. The following two case examples
demonstrate the types of adjustments that can be
made to address these difficulties.
Case Example #1
Ms. T. was a 72-year-old retired schoolteacher who
presented with pri- mary sleep maintenance insomnia. Initial evaluation showed that she manifested many sleep-disruptive habits such as frequent napping while watching the evening news and remaining in bed as much as 10 hourson some of her more difficult nights. Given these findings, CBT was initiated. Pretreatment sleep logs had shown Ms. T.’s average sleep time at night to be approximately 6.5 hours, so she was initially restricted to 7 hours in bed each night at the start of treatment. Five days after her first appointment she phoned the therapist with concerns about markedly increased daytime sleepiness. In fact, she noted that she had fallen asleep in her car after having stopped for a traffic light. Because of this, she had become con- cerned about driving her car and wondered what she shoulddo. Questioning of the patient indicated that she had adhered to the TIB restriction very strictly and she was sleeping very soundly on most nights. However, she continued to feel sleepy in the daytime and had to constantly fight off naps. Hence, the therapist suggested she increase her time in bed by 30 minutes per night to try to reduce this sleepiness. He also suggested that she ask her husband to take over all driving responsibilities until she returned to the clinic for follow-up 1 week later. Upon her presentation for her ensuing appointment, she reported reduced daytime sleepiness with the increased time in bed.
Her sleep logs showed she was sleeping fairly well at night with very few extended awakenings. As she continued to report some mild sleepiness, the therapist suggested she addanother 15 minutes to her TIB each night. After trying this new TIB prescription, she reported an elimination of her daytime sleepiness and a continuation of improvedsleep at night.
70
Case Example #2
Ms. C. was a 66-year-old retired female who presented
with severe sleep-maintenance insomnia that developed after her retirement. Following an assessment that suggested a diagnosis of primary insomnia, she was begunon a course of CBT. After 2 weeks of following this regimen she returned to the clinic anxiously explaining that her sleep had gotten worse. Furthermore, she reported that the strict behavioral regimen made her very anxious and she felt under too much pressure to sleep. To address this problem, a more lenient TIB prescription was established and the patient was allowed to take a brief (30 min) daytime nap each day if she felt the need to do so. With these changes, the patient was able to relax and gradually showed nocturnal sleep improvements over the ensuing month of treatment.
Reviewing and Reinforcing Treatment Adherence
In addition to assisting patients with setting theirsleep and wake times, use the follow-up sessions toreinforce the patient’s adherence to the prescribedCBT regimen and completion of the Constructive WorryWorksheet and Thought Records. Assess patientadherence by reviewing the sleep rules andrecommendations integral to this pro- gram (see
Chapter 3 for list of sleep rules) and asking thepatient about his adherence to each one. You shouldfreely compliment the patient who closely follows alltreatment recommendations and com- pletes thecognitive homework exercises. In doing so, however, it isparticularly useful to point out the relationship betweenthe patient’s treatment adherence and improvementnoted by his sleep logs or other outcome measure
being used (see Chapter 2 for a list of meas- ures andself-reports). For example, you may make commentssuch as, “You have done an excellent job followingthrough on the strategies we discussed last time. As youcan see, your efforts have paid off. Your logs show that youare now sleeping much better. Keep up the good work!” In
providing such comments it is important to remaingenuine and avoid patronizing the patient. Thus,language that feels comfortable and consistent withthe therapist’s usual interactional style should beused in reinforcing adherence.
71
Troubleshooting: Behavioral Component
To a great extent, troubleshooting consists of
assessing patient adherence to the sleep improvement
guidelines and sleep hygiene recommendations. Often
a lack of treatment response is traceable to the
patient’s misunder- standing of, or non-adherence to,
treatment recommendations. By far, the most common
adherence problems are patients’ failures to adhere
to a standard wake-up time, to get out of bed during
the night when they are unable to sleep, and to
refrain from unintentional sleeping during the day-
time. A careful review of sleep logs should be
employed to identify non- adherence with prescribed
wake-up times. Also, specific questioning of the
patient to determine the occurrence of daytime
napping episodes and extended periods of
wakefulness spent in bed should be conducted. When
such problems are identified, review the behavioral
regimen with the patient and talk about methods the
patient can use to avoid these practices in the future.
The following series of case examples demonstrate
how patients’ difficulties enacting the sleep
improvement guidelines and sleep hygiene
recommendations may be managed during follow-up
sessions.
Case Example #3
Mr. X. was a 61-year-old patient who presented to our
sleep center with a complaint of sleep-maintenance insomnia. Evaluation of this patient sug- gested that he suffered from primary insomnia and warranted a trial of behavioral therapy. He was provided our CBT treatment as described in this manual. After 1 week of treatment, he reported back to our center noting little improvement. Froma review of his sleep logs and a discussion with him, it was discovered that he failed to adhere to a standard wake-up time as instructed. In fact, on three of the nights during the first week of treatment, he stayed in bed over 2 hours beyond his prescribed wake-up time reportedly to compensate for periods of wakefulness during the night.
Also, he admitted to failing to get out of bed during extended periods of wakefulness because he thought that ifhe would lie in bed long enoughhe would eventually go to sleep. Although he adamantly denied daytime napping, he did admit to some unintentional dozing around 7:00 PM each evening whilehe was reclining on the couch watching TV.
To correct the patient’s sleep problem, the therapist first explained the deleterious effect the noted nonadherencewould continue to have on
72
Mr. X.’s sleep. Subsequently, the patient and therapist jointly decided that the patient would place his alarm clock in a location far from his bed so that he could not reach it without getting up. This measure was used to force the patient to get out of bed at the selected wake-uptime. In addition, the therapist helped the patient decide what activities he might do instead of lying in bed when he experienced extended nocturnal awakenings.Specifically, the patient was instructed to consider watchingTV, reading magazine articles, or listening to music. Finally,the patient was encour- aged to refrain from reclining whilewatching TV in the evening and to have his wife help him remain awake during the early evening hours. At a follow-up session 1 week later, the patient showed markedly improved adherence and a reduction in his sleep maintenance difficulty.
Case Example #4
Mr. M. was a 52-year-old college professor who
presented with sleep onset and maintenance difficulties. After a thorough assessment it was determined that he suffered from primary insomnia and would benefit from CBT. After 2 weeks of this treatment, Mr. M. returned to the sleep clinic noting marked improvement in his sleep-onset problem but contin- ued intermittent difficulties maintaining sleep. Upon questioning by the therapist it was discovered that Mr. M. followed the recommendation of getting out of bed in the middle of the night when he could not sleep. However, on such occasions, he typically watched a late-night talk show on television and found he did not want to return to bed before he saw the ending to this show. Since Mr. M.’s TV watching seemed to be extend- ing his middle-of-the-night awakenings, he was discouraged from contin- uing this practice and was encouraged to engage in light, recreational reading instead. The patient subsequently complied with this recommen- dation and soon became able to sleep through most nights.
Case Example #5
Mr. R. was a 47-year-old professional who presented
with an 11-year history of difficulty initiating and
maintaining sleep. The initial evalua- tion suggested a history of sleep difficulties that reportedly were sometimescaused by conflicts with coworkers and supervisors. Nonetheless, the patient appeared to often allot 9 or more hours for sleep at night and he reported he preferred to keep his bedroom TV playing so he would have
73
something to distract him if he did awaken during the night. When the CBT regimen was introduced, he appeared somewhat skeptical, particu- larly when it was suggested that he stop watching TV in his bedroom and that he reduce his time in bed. Although the patient statedhe would try the regimen, he showed evidence of only marginal adherence when he returned for his subsequent treatment session. Specifically, he continued his former practice of keeping the TV on all night and he often stayedin bed at least 1 hour more than recommended. Although Mr. R. continued to voice skepticism, he eventually did agree to conduct a series of “clinical experiments” on himself to see the effects of each of the disputed CBT suggestions. Hence, during the subsequent 2 weeks he agreed to remove himself from his bedroom when he couldn’t sleep instead of watching TV in bed. When, on a subsequent visit, he reported being surprised that this strategy did lead to gradual sleep improvement, he agreed to reduce his time in bed to an amount that closely approximated the therapist’s sugges- tions. Upon his subsequent return, he again agreed the clinical experimenthad benefited him. Although the patient noted that he would not agree to avoid sleeping in on weekend mornings, he did agree to stay in bed no longer than 1 hour beyond his weekday rising time. Since the patient had made reasonable progress and seemed very resistant to further changes, the therapist chose to commend him on his accomplishments and refrained from attempts at additional interventions that very likely would have been met with excessive resistance.
Case Example #6
Ms. Q. was a 45-year-old employed woman with difficulty
initiating sleep and subsequent daytime fatigue. She readilyaccepted the sleep hygiene recommendation to exercise regularly as she indicated she believed that exercise would help her sleep more soundly at night and give her more pepin the daytime. However, 4 weeks into treatment, she had failed to estab- lish any regular exercise program. She complained that she had difficulty finding time for exercise due to her ongoing work and family responsibili- ties. The therapist suggested that she try to integrate some exercise
by using stairs instead of the elevator whenever possible ather work site and taking a brisk 20-minute walk around the parking deck at work during her lunch break at least three times per week. Ms. Q. found these suggestions helpful and subsequently was able to initiate this plan over the subsequent several
74
weeks. By the conclusion of treatment she reported that she was beginning to see the benefits of her exercise on her sleep and daytime energy level.
Case Example #7
Mr. J. was a 51-year-old, divorced man who lived alone.
He had long had problems sleeping and had developed thehabit of having 1–2 shots of bourbon in the evening shortly before bedtime. Typically the patient had little difficulty falling asleep but he often awakened and could not return to sleep easily. Whereas the patient’s enactment of most treatment recom- mendations was very acceptable, his sleep logs showed he continued to con- sume alcohol close to bedtime several nights per week. Often when he did so his subsequent sleep was rather fragmented. To address this problem the therapist used the patient’s sleep log data to highlight the association between his bedtime alcohol consumption and subsequent poor sleep. The therapist also suggested the patient move his alcohol consumption to an early time so that it did not interfere with his sleep. In response to this suggestion the patient reduced his use of alcohol and generally refrained from alcohol consumption after his evening meal. Subsequent to these changes the patient’s nighttime awakening problem diminished.
Troubleshooting: Cognitive Component
Constructive Worry: The most common problem
reported with this proce- dure tends to be allotting
insufficient time to complete it. Troubleshooting this
problem requires encouraging patients to examine
their schedules and prioritize a 15-minute block in
which to complete the Constructive Worry Worksheet.
It may also help to check with the patient’s
understanding of the rationale. If the rationale is not
understood, it will be less likely that patients will
make the scheduling of this activity a priority.
Sometimes patients become so activated that they
have trouble completing this activ- ity. In such cases it
is important to complete one example in the follow-up
session to ensure that the patient has the ability to
complete such an exer- cise and to reduce the
likelihood of becoming too aroused to successfully
complete it on their own.
Cognitive Restructuring : There are a number ofpotential problems that can occur with patientscompleting a Thought Record. Such barriers
75
include difficulty remembering to complete one,
difficulty with complet- ing one or more of the
columns, a denial that thoughts are contributing to
the problem, predicting that it will not be helpful,
and no mood change following the exercise. Such
problems can usually be worked through in session.
For example, the problem of not remembering to
complete a Thought Record can be addressed by
scheduling a Thought Record around the same time
each day. Problems completing one or more columns
are best solved by completing a number of Thought
Records in session. The questions you ask to direct a
patient through the Thought Record should be written
down, so the patient can refer to these questions
when completing one on his own. Those patients who
regularly use the Thought Record typically report
that they are extremely helpful in mak- ing a
cognitive shift. Patients who present doubts about the
usefulness of Thought Records may be encouraged to
try using this instrument as a behavioral experiment.
For example, you can ask the patient to complete the
Thought Record for 2 weeks and “suspend judgment”
about whether it is helpful until then. Agreeing to
evaluate the effectiveness at a later date is often
satisfactory to the patient. When reviewing whether
the Thought Records were helpful, look at all the
available data including any possible mood
improvements in the final column (i.e., “Do you feel
any differently?”), or possible improvements in sleep.
Often, the problem to “troubleshoot” in regard to
Thought Records is that the patient resisted the
assignment and did not complete one. It is important
to assess reasons for non-completion in an open and
non- judgmental fashion. Are they convinced it will
not be helpful? Some find it contrived, and will say,
“I know my thoughts are irrational, but that’s what I
feel.” It is important to validate that the patient’s
thoughts and feelings are valid. It is also important
to validate that it must seem as though it would be
difficult to change given how automatic these
thoughts are. Ask to explore whether there may be
costs to having such strong conviction in these
thoughts and whether these thoughts may be adding
to the problem (i.e., emotional reasoning). In
addressing such thinking it is useful to consider the
methods for managing patients’ cog- nitive errors
discussed in the previous chapter.
All of the previously mentioned troubleshootingadvice should address the common problem that thepatient’s mood does not improve after completingthe Thought Record. When there is no moodimprovement,
76
it typically means that one of the columns was not
completed correctly. For example, the thoughts
recorded are not related to the mood (e.g., the
thought that is most strongly connected to the mood
is not recorded). In this case, go through a series of
questions to elicit more thoughts. If some thoughts
are related to one mood and other thoughts are
related to a different mood, complete separate
Thought Records to deal with each mood state or
emotionally charged thought. For example, if anger
and fear are recorded and the thoughts seem to
relate to either one or the other mood state,
complete one Thought Record for the anger-related
thoughts and one for the anxiety-related thoughts.
Also, spend more time in the Evidence against the
Thought column to ensure that ade- quate attention
is paid to disconfirming evidence. Lastly, generate
more “believable” Adaptive/Coping Statements.
These statements should be rated for believability. If
they are not believed strongly, it will be neces- sary
to rewrite them in a way that is more believable.
Case Example #8
Ms. S. was a 33-year-old female who presented with sleep
onset insomnia. She reported prominent worries about sleep and nightly dependence on sleep medications. She had a history of problems with anxiety. An examinationof her sleep logs revealed excessive time-in-bed and variable bedtimes and rise times. CBT recommendations included psychoeducation about sleep need, instructions to reduce her time in bed to match her sleep production (e.g., 7 hours), establishing a regular bedtime and rise time, and to get out of bed when unable to sleep (i.e., stimulus control). Ms. S. returned to the clinic 2 weeks later and reported almost no adherence to the sleep schedule or stimulus control instructions. She explained that she could not adhere to the treatment because she needed 8 hours tofunction. The next two sessions weredevoted to restructuring the belief that she could not function without 8 hours of sleep. Her Thought Records revealed a core belief of helplessness. She believed that
she had limited coping abilities and that she was “always one crisis away from becoming permanently disabled.” She had images of herself in a wheelchair in a “mental institution.” These beliefs were formed many years prior when she suffered from debilitating panic attacks. Focusing on the positive instances of coping, which included her gaining mastery over her panic attacks, allowed her to modify her helplessness beliefs. This cognitive shift resultedin almost total adherence to the behavioral recommendations
77
and a mean posttreatment sleep onset latency in the normal range (posttreat- ment SOL = 21 minutes, instead of the pretreatment sleep onset latency of 184 minutes).
Tracking Down “Missing” Sleep
It is not uncommon for some patients to present with
a complaint that they “do not sleep” for days, weeks,
or even months on end. Patients with this complaint
will often produce sleep logs that show very
limited amounts or no sleep on many nights each
week. Such cases may require use of special
cognitive strategies to conduct some “detective work”
to uncover the sleep that is “missing.” There are good
reasons to do a little detective work in such cases.
First, human beings are often unsuccessful with
attempts to stay awake for more than a couple of
days. “Trying” to stay awake is very difficult, as the
body finds a way to produce short or brief unplanned
bouts of sleep when confronted with long periods of
wakefulness. Sleep-deprivation experiments often
must resort to using high degrees of stimulation
(i.e., noise and light in a laboratory setting) and
experimenter intervention (i.e., talking to the
patient) in order to successfully keep someone
awake. What makes the report of no sleep in a person
with insomnia even more incredible is that they report
not falling asleep under conditions of almost no
stimulation at all. For example, they report that they
lay awake in bed, in the dark, with no noise, all night
long. Also, there are plenty of data to document a
discrepancy between objective indices of sleep (i.e.,
brain wave activity on a polysomnogram or activity
monitoring on an actigraph) and subjective reports
(i.e., sleep log) of “I don’t sleep.” There is controversy
as to what accounts for the discrepan- cy, as some
other physiological measures (i.e., spectral analysis)
have shown increased high frequency activity in the
brain of those with a so-called subjective-objective
discrepancy. One common cognitive error in such
insomnia sufferers is dichotomous thinking. Large
amounts of time spent awake is viewed as “no sleep.”
There may be a “cost” to believing that one does not
sleep (irrespective of whether there is objective data
to the con- trary). The cost to believing “I don’t sleep”
is increased anxiety, and anxi- ety increases the
likelihood of sleep disruption. Following is an example
of some “detective work” in investigating the report of
“no sleep.”
78
Case Vignette
T: I see on your Thought Record that your thoughts have included “I can’t believe I went another night without sleeping.” “I haven’t slept in over 2 weeks.” and “Can you die from not sleeping?” I also notice that you have rated frustration and anxiety at 100%.
P: You’d be anxious and frustrated if you didn’t sleep either.
T: I would like us to examine whether there may be a connection between some of these thoughts and your mood. Is there any possible connection betweenthe thought, “I haven’t slept in over 2 weeks” and anxiety or frustration?
P: Of course. It’s scary to not sleep.
T: I can see how thinking you haven’t slept in 2 weeks would be scary.
I wanted to make sure that I understand this; you have not slept even
1minute in 2 weeks?
P: Well, very little anyway.
T: Oh okay, there has been some sleep, but very little?
P: Almost none.
T: I can see how it would be upsetting to have very
little sleep, but I could see how it would be even
more upsetting if there was absolutely zero sleep. In
fact, I have never had a case with no sleep for 2
weeks so I am relieved to hear there has been at
least a little bit of sleep. Can you estimate how
much sleep is a “little bit of sleep” over the last2weeks?
P: I don’t know, maybe a few minutes.
T: Okay, a few minutes. I remember you told me that you
were irritated when your husband woke you to tell
you that you were snoring. Was this the few minutes
we are talking about?
P: I guess. I was so irritated because I felt as though I
was just about to fall asleep and then he nudged me.
It didn’t seem like I was sleeping but I guess I must
have been. You can’t snore when you’re awake,
right? Also, I looked in the mirror yesterday and saw
the imprint of
79
my keyboard on the side of my face. So I know I fell
asleep yesterday at the computer but I don’t really
remember it. So that’s a little more time.
T: This is good. We also need to remember that you
recorded two day- time naps over the last week. It is
important for us to “find forgotten sleep,” especially
since you have said that thinking you don’t sleep at
all increases your anxiety. When you are more
anxious, are you more likely to have worse sleep?
P: Well, yes.
T: Then it would be important for us to make sure
you are not telling yourself something that makes
you more anxious, right?
P: I guess. Although I don’t think I am sleeping thatmuch, I don’t usually remember seeing the clock orgetting up between 2–6 AM, so it’s possi- ble that Iam sleeping a little during that time.
T: So we have a few minutes during the day, a few
minutes in the first half of the night, and about a 4-
hour window in the second half of the night when
there is an undetermined amount of sleep. It looks
like your body is really working to give you bits of
sleep here and there, even if you are not always
aware of it, and even if it doesn’t always feel like
it. Does this help at all with the thought that you
might die from not sleeping?
P: Well, I’m probably not going to die. It was just scary
to think I wasn’t sleeping at all. I guess I’m sleeping
a little.
T: Do you think that being less anxious about this may
allow you to get even more sleep?
P: I hope so!
Summary
Although we have no hard and fast rule about the
number of follow-up sessions to provide patients,most of our primary insomnia patients respond totreatment in 3–4 sessions total. Of course, there arethose who
80
respond more gradually but do achieve a satisfactoryoutcome. In the end, therapy should be guided by the
patient’s sleep performance reflected by sleep logdata and by the patient’s subjective appraisal.Optimal sleep performance is characterized bysleeping soundly at night and having no daytimesymptoms (e.g., fatigue, impaired concentration,distress about sleep) of insomnia. In this case, sleeplogs would show the patient has a regular sleep-wakeschedule and typically has little difficulty fallingasleep or staying asleep through the night. Alongwith this observation, the logs and the patient’s self-
report should indicate that the final morningawakening typically occurs slightly before the alarmclock sounds. If the patient sleeps soundly but mostoften is awakened by the alarm, it is likely that thepatient could and would sleep a little longer eachnight had the alarm not be set. In such cases, it isusually useful to expand the TIB window somewhatuntil the sleep pattern described emerges. However,once the patient achieves a sound sleep pattern atnight and is satisfied with his daytime function,therapy termination may be considered.
When therapy termination is discussed with patients,
it is important to review all of the new sleep and
insomnia management skills they have learned
during the treatment. In this regard, it is important
to empha- size that they now have the “tools” they
need to manage their sleep prob- lems and combat
any future bouts of insomnia they may confront. It is
also useful to emphasize that future nights of poor
sleep are not only pos- sible but also are very likely
to occur from time to time. However, it is important
to emphasize to that patient that he now is well
equipped to manage such episodes effectively so that
they do not persist. In addition to this information, we
have found it helpful to give the patient “permis-
sion” to schedule any future “refresher sessions” he
feels are necessary to reinforce what he has learned
and to help the patient through more difficult
episodes. Through use of such strategies we have
found a large percentage of those patients we treat
are able to continue the treatment on their own with
minimal or no further assistance from our clinic.

Chapter 6 Considerations in CBT Delivery: Challenging P atients and T r eatment S ettings
Overview of the Treatment Challenges
Thus far, the discussion in this manual has
summarized strategies to employ during individual
therapy sessions with unmedicated primary
insomnia patients. Of course, many patients who
present for treatment do so in the context of ongoing
use of sleep medications. Many other treatment-
seeking patients have concurrent comorbid medical
or psy- chiatric conditions that contribute
significantly to their persistent sleep difficulties.
Furthermore, not all patients who seek insomnia
treatment present to psychologists or other providers
who have training and skills in Cognitive-Behavioral
Therapy techniques. In fact, the majority of
treatment-seeking insomnia patients present to
primary care or other types of medical venues where
individualized one-on-one sessions with a CBT
therapist are either unavailable or not practical.
The various types of patients with insomnia as well
as the varied settings in which they present for
treatment present special challenges to those wishing
to implement the CBT procedures described herein.
The discussion in this chapter considers how CBT
may be disseminated to the types of patients and
settings mentioned.
CBT With Hypnotic-Dependent Insomnia Patients
As noted in Chapter 1, various medications are
commonly employed for insomnia management.
Included among these are various types of
benzodiazepine receptor agonists (BZRAs) that have
been well tested and have FDA approval for
insomnia treatment. At times, other BZRAs that have
FDA approval for treating anxiety, but not insomnia,
83
are prescribed alone or in addition to the approvedmedications to treat sleep difficulties. In addition, avariety of other medications includingantidepressants such as the sedating tricyclics (e.g.,doxepine) and tra- zodone, and the atypicalantipsychotic, quetiapine, are often used to managepatients’ sleep complaints. These latter medicationslack FDA approval and are used “off-label” fortreating insomnia. Finally, various over-the-countermedications are available and are used frequently byinsomnia patients in their efforts at self-management.
Over the years, concerns have been raised aboutprotracted use of medica- tions to address chronicprimary insomnia. Although there is considerable“clinical lore” supporting the prescription medicationsused “off-label” for sleep, currently there are few datato support their safety and efficacy for long-termtreatment of primary insomnia. Likewise, there areextremely limited data concerning the safety andefficacy of those sleep medications available withoutprescription. With some of the first generation FDA-approved BZRA hypnotics, medication tolerancedevelops with continued use such that patientsexperience reduced efficacy while being maintainedon stable therapeutic doses for extended periods oftime. Abrupt with- drawal of such medications oftenresults in a transient, albeit distressing, worsening ofsleep that convinces many patients to quickly resumetheir medication use. In contrast, some of the longeracting BZRAs may result in unwanted next-day effectssuch as sluggishness or “hangover.”
Fortunately the newer generation BZRAs (e.g.,
zolpidem, eszopiclone, zaleplon) have far less
pronounced unwanted properties such as these, and
some such agents have proven safe and effective over
extended peri- ods of continued use. Nonetheless, as
displayed by the following case description, long-
term use of hypnotics can be problematic to some
patients for reasons other than those mentioned thus
far.
Case Example: Insomnia and Medication Dependence
Ms. R. was a middle-aged married woman who
presented to our clinic with insomnia complaints. At the time of her presentation, she reported a history of sleep difficulties dating back about 10 years to a time when she was having ongoing medical problems. She noted that at that time she had undergone surgery on her left leg and the surgical wound did not heal prop- erly. She noted pain, immobility and general distress over her condition. In
84
that context, she experienced the onset of her sleep difficulties. Shortly after her sleep problem began, she obtained a prescription for lorazepam to treat her sleep difficulty, and she had taken that medication almost nightly since that time. She also subsequently received an additional prescription for zolpidem, 10 mg, to help her sleep. Hence, when she presented for treatment, she was taking 10 mg of zolpidem along with .5 to 1 mg of lorazepam on a nightly basis as sleep aids. Her stated goal for treatment was to learn how to sleep without sleep medications. However, she noted that she became very anxious and unable to sleep without lorazepam and she admitted she thought she would be unable to initiate and maintain sleep unless she took both of her sleep medications. In support of this, she noted that her efforts to stop these medications had been met with her experiencingelevated anxiety about sleep and pronounced wakefulness during the subsequent night. With her medications, she indicated that she was able to function in the daytime without severe daytime sleepiness (Epworth Sleepiness Scale = 9). However, she did indicate that her sleep still was not ideal and she experienced a significant level of fatigue many days each week despite her nightly use of medicinal sleep aids. Her sleep log shows her sleep pattern at the time of her initial clinic visit (see Figure 6.1). Despiteher nightly medication use, she still showed difficulty initiating sleep on two nights and relatively poor qual- ity sleep on several nights. This log also showed the erratic sleep scheduling common to insomnia patients in general.
Ms. R.’s case highlights many of the characteristics
commonly present- ed by those insomnia patients
who use sleep medications on a chronic basis. As her
history demonstrates, her sleep medication use
began for good reason during a time she was
recovering from a painful medical condition that
disrupted her sleep. However, she was initially
prescribed a BZRA medication for sleep that has FDA
approval for anxiety man- agement but not
insomnia. While continued on this medication, she
was given an FDA-approved hypnotic as an
additional sleep aid. Her history suggests that, over
time, she developed a psychological depend- ence on
such medications as sleep aids. Indeed, her efforts to
stop these medications were met with increased
sleep-focused anxiety and marked sleep disruption.
When patients like Ms. R. are interviewed thorough-
ly, they often report a general lack of self-efficacy in
regard to their abil- ity to obtain adequate sleep. In
a sense, they have lost faith in themselves as
sleepers. As a consequence, they come to rely on
sleep medication(s) to obtain the sleep they need.

Sleep Log: Sleep Medication User
86
Insomnia patients who use hypnotics chronically
present with many of the cognitive and behavioral
treatment “targets” discussed in previous chapters.
Specifically, they have catastrophic beliefs about the
daytime effects of their sleep difficulties as well as a
misunderstanding of how their sleep habits may
contribute to their insomnia. Accordingly they
demonstrate many of the common sleep disruptive
compensatory prac- tices (e.g., daytime napping,
erratic sleep schedules, extended waking periods
spent in bed) seen in medication-free primary
insomnia patients. However, they also present a
unique set of cognitions and behaviors that require
treatment attention. Commonly such patients have
strong beliefs that their insomnia is “due to a
chemical imbalance” so they conclude that they are
unable to sleep without a medication. Many appear
rather conflicted, on the one hand believing that
long-term sleep medication use is harmful, while on
the other hand feeling helpless to sleep without some
sort of sleep aid. Some patients who are concerned
about their medication use cut their sleeping pills in
half and surprisingly sleep well on subtherapeutic
doses yet are unable to wean themselves completely
from such medications without a marked worsening of
sleep. Others will intermittently try going to bed
without their usual medication to “see how they do”
without it. Of course, this latter strategy usually
tends to increase sleep vigilance, which, in turn,
makes sleeping more difficult. Thus, chronic
medication users present additional cognitive and
behav- ioral targets that merit the therapist’s
attention.
Since many chronic hypnotic users present with the
desire to discontin- ue their sleep medications, it is
important to implement a treatment plan that
enables them to do so yet maintain or reestablish a
satisfacto- ry medication-free sleep pattern. Current
evidence (Morin et al., 2005; Belleville et al., 2007;
Soeffing et al., 2007) suggests a therapy that com-
bines CBT techniques with a structured medication-
tapering program produces optimal results with
medication-dependent patients. Typically it is helpful
to initially have the patient continue on her usual
medica- tion, and to plan to take this medication
routinely, as prescribed, prior to going to bed each
night. While the medication regimen remains sta-
ble, treatment should commence by initiating the
CBT strategies described in detail in the preceding
three chapters. While patients receive CBT
instructions, they should be dissuaded from making
any changes in their sleep medication practices.
Specifically, they should be
87
discouraged from changing their medication dosages
or experimenting with medication-free nights. During
the course of this treatment it may be helpful to
identify some unhelpful beliefs about sleep
medications and have patients complete Thought
Records (see Chapter 4) as “home- work” to address
such beliefs. It is also important to have patients
adhere strictly to the behavior strategies discussed in
Chapter 3 to pro- duce a consolidated and consistent
sleep pattern while they are still tak- ing their
medications. Encouraging implementation and
adherence to these strategies often results in
improved sleep patterns and enhances chances for
success in the subsequent medication taper process.
Once the patient successfully implements the CBTstrategies discussed in the previous chapters andshows a stable sleep pattern for at least 2 consec-utive weeks, a medication-tapering strategy can beintroduced. From a safety viewpoint, mostprescription and over-the-counter medications takenfor sleep can be discontinued fairly rapidly withoutuntoward med- ical concerns. However, patients whoare dependent on sleep medications usually are moresuccessful discontinuing such medications if allowedto taper them more slowly and deliberately. In thisregard, strategies discussed elsewhere (Belleville etal., 2007, Soeffing et al., 2007) have provenefficacious for such patients. These approaches allow aslow, graded, “step- down” approach to tapering thatoffers the patient a gentle pace at fading themedication while allowing some sense of graduallyincreasing self- efficacy in regard to thediscontinuation process. For example, the approachdescribed recently by Morin et al. involves thefollowing sequence of steps: (1) setting a goal formedication use/reduction each week; (2) when morethan one medication is being used, reduction to asingle medication at a stable dose is set as the firstgoal; (3) the initial dosage of the medication isreduced by 25% every 2 weeks until the lowest avail-able (therapeutic) dosage is reached; (4) drug-free
nights are gradually introduced with drug-free nightsbeing planned in advance; and (5) the number ofdrug-free nights per week is gradually increaseduntil the patient is medication free. While institutingthis sort of withdrawal plan it is important to have thepatient continue monitoring her sleep with the sleeplog and to continue with the cognitive tools(Thought Records, Constructive Worry Worksheets) asneeded. It is also important to moni- tor CBTadherence using the techniques outlined in Chapter 5.
88
Whereas this combined approach tends to produce
the best results, patients may vary in the success
they achieve. Some show a good response and
become able to sleep medication free. Others
experience setbacks along the way due to
unexpected stressors or other factors. Some patients
may view such setbacks as indications of treatment
fail- ure, so it is helpful to assist such patients in
reframing such occurrences in constructive manners.
Again, use of Thought Records may help with this
problem. However, some patients may not succeed
with medication discontinuation due to ongoing
stressors or other life circumstances that demand
their attention. Like other problem areas that merit
a certain degree of readiness on the part of the
patient to change, discontinuation of hypnotic
medication requires a level of readiness and
commitment to the treatment processes discussed
herein. Hence, a thorough assessment to determine
the patient’s readiness for the strategies described
may be useful prior to initiation of this approach.
Treating Insomnia Patients With Comorbid Disorders
Whereas many insomnia patients encountered
clinically suffer from pri- mary insomnia, a fargreater proportion of all treatment-seeking insom-nia patients present with complex comorbidconditions. A variety of medical conditions, andparticularly those that result in chronic pain,breathing difficulties, or immobility, can give rise toinsomnia prob- lems. Likewise, a large proportion ofpsychiatric conditions have insom- nia as a primarypresenting symptom. Furthermore, manymedications prescribed for the treatment of medicaland psychiatric conditions may have insomnia as acommon side effect. Finally, excessive use of alcohol,
caffeine, and various illicit substances may cause oradd to insomnia problems. In a sizable proportionof patients, a mixture of medical, psychiatric, and
substance-related causes of insomnia coexist andcom- plicate insomnia management.
In cases of comorbid insomnia, it is always helpful to
optimize manage- ment of the comorbid medical or
psychiatric conditions to optimize insomnia
treatment outcomes. In some cases, successful
treatment of the comorbid disorder(s) results in
insomnia remission. However, fre- quently this is not
the case since factors in addition to or other than the
89
comorbid condition may sustain insomnia over
time. Although the onset of insomnia may relate to
endogenous physiological changes or acute stress
reactions to the onset of a comorbid illness, a host of
cogni- tive and behavioral factors may perpetuate
insomnia over time. Even among individuals whose
sleep disturbance initially emerged as a symp- tom of
the comorbid condition, the nightly experience of
unsuccessful sleep attempts can result in conditioned
arousal and subsequent efforts to make up for lost
sleep by spending excessive time in bed each night
or napping during the day. These practices can result
in prolonged sleep difficulties because they
adversely affect homeostatic and circadian
mechanisms that control the normal sleep-wake
rhythm. Since such sleep-disruptive cognitions and
habits may play important roles perpet- uating
insomnia in comorbid patients, CBT strategies may
be useful as primary or adjunctive insomnia
treatment for these individuals.
To date, a relatively limited number of randomizedclinical trials have investigated the efficacy of CBTfor treating insomnia patients with var- ious types ofcomorbid conditions. The more convincing studieshave focused on medical disorders and havesuggested that CBT is efficacious for treatinginsomnia in patients with chronic pain (Currie et al.,2000), fibromyalgia (Edinger et al., 2005), mixed oldermedical patients (Rybarczyk et al., 2002) and cancersurvivors (Savard et al., 2005). Well- conductedrandomized trials of CBT for insomnia treatment inpsychi- atric samples have generally been lacking.However, a few clinical case series studies(Morawetz, 2003; Kuo, et al., 2001) have suggestedthat CBT does seem effective for treatment ofinsomnia in patients with comorbid depression.Whereas these findings are encouraging, addi-tional randomized trials are needed to confirm theusefulness of CBT with psychiatric patients.
Nonetheless, it is useful to consider CBT insomnia
treatment for those psychiatric patients who present
obvious cognitive and behavioral treat- ment targets
discussed in the previous chapters. The following
case example shows the potential usefulness of CBT
strategies with a psychi- atric patient. The patient
described here suffered chronic insomnia comorbid
to a serious anxiety disorder.
90
Case Example: Insomnia and Comorbid Anxiety Disorder
The patient was a 56-year-old married man who
participated in a CBT insomnia treatment study at a VA hospital. The patient has been seen for treatment at the hospital for a number of years in relation to the combat-related posttraumatic stress disorder he developed as a result of his service experience during the Vietnam War. Atthe time the patient pre- sented for the study, he reported a 15-year history of chronic insomnia problems. Specifically he reported that he would typically sleep soundly for only about 2.5 hours per night and then he would toss and turn the remainder of the night. He reported he was receiving ongoing pharma- cotherapy (Citalopram) for his PTSD, and his symptoms other than his sleep difficulty were relatively well controlled.
As part of his initial evaluation for the treatment study, he underwent diagnostic sleep monitoring (polysomnography)in order to rule out sleep disorders not detectable from interview (e.g., sleep apnea). Results showed no evidence of sleep apnea or other medically based primary sleep disor- ders. However, the recording showed very poor sleep with a sleep onset latency of 63 minutes, 90 minutes of wakefulness during the middle of the night, and a total sleep time of only 4 hours. A sleep log maintained by the patient for several weeks prior to treatment corroborated the findings from his sleep recording. Specifically this sleep log showed an averagesleep onset latency of 82 minutes, an average wake time during the night of 165 minutes, and an average sleep time of only 4 hours and 25 minutes per night. The patient’s sleep log for the first week of this monitoring period, which captures this general pattern of sleep difficulty, is shown in Figure 6.2. This log shows the patient’s variable sleep schedule as well as his penchant to allot excessive times each night for sleep.
To treat this condition the patient received four biweekly 30- to 60-minute sessions that included the psychoeducational information and sleep improvement recommendations presented in Chapter 3. During this time period, no changes were made in his pharmacological treatment for his PTSD condition. Over the course of the CBT treatment, the patient’s sleep improved markedly. Sleep
logs maintained by the patient immediately fol- lowing treatment showed an average sleep onset latency of 15 minutes per night, an average wake time during the night of slightly less than 31 min- utes, and an average total sleep time of 5 hours and 45 minutes. Figure 6.3

shows the first week of these sleep log data collected by the patient follow- ing treatment. This log shows the marked improvements in the patient’s sleep pattern as well as greater stability in his chosen sleep schedule. Whena follow-up of this patient was conducted 6 months after he completed treatment, his sleep pattern continued to show the improvement displayed immediately after treatment with virtually no change in his sleep or wake time measures.
Whereas treatment results like these suggest that theCBT strategies are well suited for treating those withcomorbid insomnia, there is still need for somecaution when employing these techniques with suchpatients. Admittedly, given the limited datasuggesting the efficacy of CBT with comorbidpatients, there is much to be learned aboutoptimizing out- comes with these individuals. Indeed,there are many questions yet to be answered. Amongthe more pertinent are (1) How can we best combineCBT with pharmacotherapy and other medicalmanagement of the exist- ing comorbid disorder? (2)
Do the specific sleep-focused CBT techniques need tobe altered or augmented in any way to maximize
outcomes with comorbid insomnia? (3) Should CBT forinsomnia be incorporated into more global cognitive-behavioral protocols that exist for various comor- bidconditions (e.g., depression, anxiety disorders, etc.)?
and (4) Does CBT for insomnia in comorbid patientsrequire more extended therapy and follow-up thancommonly required for primary insomnia? These,among many other questions, need to be addressed
before this treatment can be confidently extended tovarious other comorbid groups. For a more thoroughdiscussion of this topic, the reader is referred to therecent excellent review article by Smith et al. (2005).Nonetheless, the research conducted to date as wellas with results with cases such as the one pre- sentedhere encourage further applications of this modalityfor addressing comorbid insomnia problems.
Dissemination of CBT Across Settings
Whereas CBT has proven efficacy for primaryinsomnia and holds much promise for treating thosewith various comorbidities, it is cur- rentlychallenging to make this therapy available to all whomay benefit from it. Whereas 10% to 15% of thepopulation has chronic insomnia,
94
there are currently a paucity of trained providers
who offer the treat- ment described in this manual.
Furthermore, those who are trained and skilled in
these techniques tend to be found in larger medical
centers or specialty sleep centers and not in the
general medical practice settings where most
treatment-seeking insomnia patients present for their
care. Thus, expanding the provider pool and
exporting this treatment to the venues wherein most
insomnia patients receive their initial treatment
remain as challenges to this therapeutic modality.
In efforts to facilitate dissemination of CBT forinsomnia, some inves- tigators have testedtreatment models suitable for medical practicesettings or the public at large. Given that insomniasufferers typically present first in primary caresettings, it seems reasonable to consider providingCBT training to those health care professionals (e.g.,nurses, general practitioners) commonly found insuch settings. Two studies designed to test theefficacy of such an approach have demonstrated thatboth family physicians (Baillargeon et al., 1998) andoffice-practice nurses (Espie et al., 2001; Espie et al.,2007) can effectively administer CBT components ingeneral medical practice settings. In contrast,Oosterhuis and Klip (1997) reported delivery ofbehavioral insomnia therapy via a series of eight, 15-minute educational programs broadcast on radio andtelevision in the Netherlands. Over 23,000 peopleordered the accompanying course material, and datafrom a random subset of these showed that sleepimprovements and reductions in hypnotic use,medical visits, and physical complaints wereachieved by this educa- tional program. Thus, itappears that behavioral insomnia treatments can beeffectively delivered by various providers anddelivery of such treatment even via mass mediaoutlets may provide benefits to some insomniasufferers. Of course, the relative efficacy of thesealternate modes of treatment delivery vis-à-vis moretraditional treatment with experienced CBT
therapists is yet to be determined.
Other efforts aimed at treatment dissemination have
tested treatment protocols that can be self-
administered outside the clinic setting. Mimeault and
Morin (1999), for example, tested a self-help CBT book-
based treatment (i.e., bibliotherapy) with and without
supportive phone consultations against a wait-list
control. Compared to the control condi- tion, those
treated with the bibliotherapy showed substantially
greater sleep improvements, and these
improvements were maintained at a
95
3-month follow-up. The addition of phoneconsultations with a thera- pist provided someadvantage over bibliotherapy alone at least in theshort term. Recently, Strom et al. (2004) tested a 5-week self-help inter- active CBT program deliveredto insomnia patients via the Internet. Althoughthose receiving CBT showed no greater improvementthan a wait-list control group, this study doesdemonstrate that treatments such as CBT can bedisseminated widely via the Internet. However, how
to ensure the value and efficacy of such applicationsremains a current chal- lenge. Nonetheless, thesestudies provide some initial ideas for widerdissemination of CBT strategies. Such efforts may be
useful to fill the void until a sufficient number oftraditional providers are trained in these strategiesand the more challenging insomnia patients will beable to access the comprehensive CBT they ultimatelymay need.
