Clinical Assessment: How and Why Does the Client Behave

Abnormally?• What is assessment?

– The collecting of relevant information in an effort to reach a conclusion

– Clinical assessment is used to determine how and why a person is behaving abnormally and how that person may be helped

• Focus is idiographic – on an individual person• Also may be used to evaluate treatment progress

Clinical Assessment: How and Why Does the Client Behave

Abnormally?• The specific tools used in an assessment

depend on the clinician’s theoretical orientation

• Hundreds of clinical assessment tools have been developed and fall into three categories:– Clinical interviews– Tests– Observations

Characteristics of Assessment Tools

• To be useful, assessment tools must be standardized and have clear reliability and validity– To standardize a technique is to set up

common steps to be followed whenever it is administered

– One must standardize administration, scoring, and interpretation

Characteristics of Assessment Tools

• Reliability refers to the consistency of a test– A good test will yield the same results in the same

situation– Two main types:

• Test–retest reliability– To test for this type of reliability, a subject is tested on two

different occasions and the scores are correlated – the higher the correlation, the greater the test’s reliability

• Interrater reliability– Independent judges agree on how to score and interpret a

particular test

Characteristics of Assessment Tools

• Validity refers to the accuracy of a test’s results– A good test must accurately measure what it is

supposed to be measuring– Three specific types:

• Face validity – a test appears to measure what it is supposed to measure; does not necessarily indicate true validity

• Predictive validity – a test accurately predicts future characteristics or behavior

• Concurrent validity – a test’s results agree with independent measures assessing similar characteristics or behavior

Clinical Interviews

• Conducting the interview– Focus depends on theoretical orientation– Can be either unstructured or structured

• In unstructured interviews, clinicians ask open-ended questions

• In structured interviews, clinicians ask prepared questions, often from a published interview schedule

– May include a mental status exam

Clinical Interviews

• Limitations:– May lack validity or accuracy– Interviewers may be biased or may make

mistakes in judgment– Interviews, particularly unstructured ones,

may lack reliability

Clinical Tests

• Devices for gathering information about a few aspects of a person’s psychological functioning, from which broader information can be inferred

• More than 500 different tests are in use– They fall into six categories…

Clinical Tests

1. Projective tests– Responses come from the unconscious mind– Mainly used by psychodynamic practitioners– Most popular:

• Rorschach Test• Thematic Apperception Test• Sentence Completion Test• Drawings

Clinical Tests

1. Projective tests– Strengths and weaknesses:

• Helpful for providing “supplementary” information• Have rarely demonstrated much reliability or

validity• May be biased against minority ethnic groups

Clinical Tests

2. Personality inventories– Designed to measure broad personality

characteristics– Focus on behaviors, beliefs, and feelings– Usually based on self-reported responses– Most widely used: Minnesota Multiphasic

Personality Inventory• For Adults: MMPI (original) or MMPI-2 (1989

revision)• For Adolescents: MMPI-A

Clinical Test: MMPIMinnesota Multiphasic Personality Inventory

• Consists of 550 self-statements that can be answered “true,” “false,” or “cannot say”– Statements describe physical concerns;

mood; morale; attitudes toward religion, sex, and social activities; and psychological symptoms

– Assesses careless responding & lying

18

Clinical Test: MMPIMinnesota Multiphasic Personality Inventory

• Comprised of ten clinical scales:– Hypochondriasis (HS)– Depression (D)– Conversion hysteria (Hy)– Psychopathic deviate (PD)– Masculinity-femininity (Mf)

• Scores range from 0 – 120– Above 70 = deviant– Graphed to create a “profile”

– Paranoia (P)– Psychasthenia (Pt)– Schizophrenia (Sc)– Hypomania (Ma)– Social introversion (Si)

Clinical Tests

2. Personality inventories– Strengths and weaknesses:

• Easier, cheaper, and faster to administer than projective tests

• Objectively scored and standardized• Appear to have greater validity than projective

tests– Measured traits often cannot be directly examined –

how can we really know the assessment is correct?

• Tests fail to allow for cultural differences in responses

Clinical Tests

3. Response inventories – Usually based on self-reported responses– Focus on one specific area of functioning

• Affective inventories (example: Beck Depression Inventory)

• Social skills inventories• Cognitive inventories

Clinical Tests

3. Response inventories – Strengths and weaknesses:

• Have strong face validity• Rarely include questions to assess careless or

inaccurate responding• Not all have been subjected to careful

standardization, reliability, and/or validity procedures (BDI and a few others are exceptions)

Clinical Tests

4. Psychophysiological tests – Measure physiological response as an

indication of psychological problems• Includes heart rate, blood pressure, body

temperature, galvanic skin response, and muscle contraction

– Most popular is the polygraph (lie detector)

Clinical Tests

5. Neurological and neuropsychological tests– Neurological tests directly assess brain function

by assessing brain structure and activity• Examples: EEG, PET scans, CAT scans, MRI

– Neuropsychological tests indirectly assess brain function by assessing cognitive, perceptual, and motor functioning• Most widely used is the Bender Visual-Motor Gestalt

Test

5. Neurological and neuropsychological tests

– Strengths and weaknesses:• Can be very accurate• At best, though, these tests are general

screening devices– Best when used in a battery of tests, each targeting a

specific skill area

Clinical Tests

6. Intelligence tests– Designed to measure intellectual ability– Composed of a series of tests assessing

both verbal and nonverbal skills– Generate an intelligence quotient (IQ)

• Most popular: Wechsler Adult Intelligence Scale (WAIS) & Wechsler Intelligence Scale for Children (WISC)

Clinical Observations

• Systematic observation of behavior

• Several kinds:– Naturalistic: in the subject’s environment– Analog– Self-monitoring: the subject records his/her

own behaviors, thoughts, emotions, etc.

DSM-IV-TR

• Published in 1994, revised in 2000 (TR)• Lists approximately 400 disorders

– Listed in the inside back flap of your text

• Describes criteria for diagnoses, key clinical features, and related features which are often but not always present

• People can be diagnosed with multiple disorders…

The DSM-IV-TR

• Multiaxial– Uses 5 axes (branches of information) to

develop a full clinical picture– People usually receive a diagnosis on either

Axis I or Axis II, but they may receive diagnoses on both

33

The DSM-IV-TR

• Axis I – Most frequently diagnosed disorders, except

personality disorders and mental retardation

The DSM-IV-TR

• Axis V– Global assessment of psychological, social,

and occupational functioning (GAF)• Current functioning and highest functioning in

past year• 0–100 scale

37

Are Classifications Reliable and Valid?

• In this case reliability = different diagnosticians agreeing on a diagnosis using the same classification system– DSM-IV-TR has greater reliability than any

previous editions• Used field trials to increase reliability

– Reliability is still a concern

38

Are Classifications Reliable and Valid?

• In this case validity = accuracy of information that the diagnostic categories provide– Predictive validity is of the most use clinically– DSM-IV-TR has greater validity than any

previous editions• Conducted extensive literature reviews and ran

field studies

– Validity is still a concern

Page 39: Comer, Fundamentals of Abnormal Psychology, 3e 1 Chapter 4 Clinical Assessment, Diagnosis, and Treatment Slides & Handouts by Karen Clay Rhines, Ph.D

Comer, Fundamentals of Abnormal Psychology, 3e

39

Are Classifications Reliable and Valid?

• Beyond concerns about reliability and validity, a growing number of theorists believe that two fundamental problems weaken the DSM-IV-TR:– Basic assumption that disorders are qualitatively

different from normal behavior– Reliance on discrete diagnostic categories

• With such concerns, DSM-V certainly will include some key changes, but the new edition is not imminent

Can Diagnosis and Labeling Cause Harm?

• Misdiagnosis always a concern– Major issue is reliance on clinical judgment

• Also present is the issue of labeling and stigma– Diagnosis may be a self-fulfilling prophecy

• Because of these problems, some clinicians would like to cease the practice of diagnosis
