shyness between ages 3-5 years.2. Temperamental trait called Behavioural
Inhibition: a tendency to show fear and withdrawal in new, unfamiliar situations
24

fear-producing situations. This is communicated to the child in explicit or implicit ways.

Treatment of Childhood Anxiety Disorders (biopsychosocial model)1. Take a good history, with collateral information.2. Do a good mental status examination.3. Physical Examination and Relevant laboratory Studies.4. Get input from interdisciplinary team: (psychology, social work,
occupational therapy, school teacher, frontline (nurses, child and youth counsellors).
5. Assess Suicide Risk

Treatment: Biopsychosocial Model6. Rule out Substance/Medication induced anxiety disorder.7. Rule out anxiety disorder due to a medical condition.8. Determine if there is more than one anxiety disorder. Anxiety triad (GAD,
Social Anxiety Disorder, and Separation Anxiety Disorder), Panic Features.
9. Determine if there is a co-morbid Psychiatric Disorder10. Determine if there is a co-morbid Medical Disorder.

30
Treatment: Biopsychosocial Model A. Cognitive-Behavioural Therapy (CBT)1. Shortest duration of treatment (mean 6 mo)2. Best outcome: about 50-60% efficacy rate.
3. Training and certification needed.4. Could be in individual/family/group forms
31
Treatment: Biopsychosocial Model CBT’s six essential components:1. Psychoeducation2. Physiologic management3. Cognitive Restructuring
32
Treatment: Biopsychosocial ModelCBT4. Problem solving skills5. Exposure6. Relapse prevention
33
Treatment: Biopsychosocial Model
School InterventionsMay involve:1.Addressing bullying, teasing, violence, abuse2.Appropriate remediation and placement.3.School psychoeducation4.Others
34
Treatment: Biopsychosocial Model
PsychotropicsRemember:1.Psychoeducation of family and child/adolescent is very important.2.Informed consent is needed.3.Need monitoring strategies for outcome and side effects.
35
Treatment: Biopsychosocial Model Reasons to use medications as an add-on1. Level of functional impairment is moderate to
severe and need to prevent further loss.2. Facilitate or hasten positive outcomes of
behavioural interventions.
36
Treatment: Biopsychosocial Model
Psychotropics: 1. SSRIs seem to be the treatment of choice for most
pervasive and impairing anxiety disorders in youth.2. TCAs are a second-line treatment due to side effects
and less overall efficacy.3. Benzodiazepines are less commonly used due to risk of
dependency, better alternatives, disinhibition.4. Atypical antipsychotics may have a role.
37
Treatment: Biopsychosocial ModelTreatment by Disorder TypeSocial anxiety disorderPanic DisorderGADAgoraphobiaSeparation Anxiety DisorderConsider:1.CBT2.Antidepressant3. Possible addition of benzodiazepine, atypical antipsychotics.

Treatment: Biopsychosocial Model
NB: “Anxiety Triad” : GAD, Separation A. Disorder, & Social Anxiety DisorderSpecific PhobiaConsider:1.CBT2.PRN benzodiazepine
39
Treatment: Biopsychosocial ModelSelective Mutism:Consider:1. Variety of Cognitive approaches: positive reinforcers, modeling, systematic
desensitization, in vivo exposure, in vivo graded exposure.2. Antidepressants may help.
Clinical Course of Anxiety Disorders in youth:
About half of treated patient were in remission after an average of 6 years.
