Assessing Psychological Disorders

Introduction

  • Clinical assessment: systematic evaluation and measurement

    • Psychological

    • Biological

    • Social

  • Diagnosis: degree of fit between symptoms and diagnostic criteria

  • Purpose: understanding the individual, predicting behavior, treatment planning, evaluating outcomes

Key Concepts in Assessment

  • Reliability: degree of consistency of a measurement

  • Validity: does the test measure what it’s supposed to?

    • Concurrent: comparison between results of one assessment with another measure known to be valid

    • Predictive: how well the assessment predicts outcomes

  • Standardization: consistent use of techniques

    • Provides normative population data

Clinical Interview

  • Clinical interview: asses multiple domains

    • Presenting problem

    • Current and past behavior

    • Detailed history

    • Attitudes and emotions

  • Most common clinical assessment method

  • Structured vs semistructured

Mental Status Exam

  • Components of mental status exam: appearance and behavior, thought processes, mood and affect, intellectual functioning, and sensorium

    • Appearance and behavior: overt behavior, attire, posture, expressions

    • Thought processes: rate of speech, continuity of speech, content of speech

    • Mood and affect: predominant feeling state of the individual, feeling state accompanying what individual says

    • Intellectual functioning: type of vocabulary, use of abstractions and metaphors

    • Sensorium: awareness of surroundings in terms of person (self and clinician), time, and place

Physical Examination

  • Physical examinations can be helpful in diagnosing mental health problems

    • Understand and rule out physical etiologies

      • Toxicities

      • Medication side effects

      • Allergic reactions

      • Metabolic conditions

Behavioral Assessment

  • Identification and observation of target behaviors

    • Target behavior: behavior of interest

  • Direct observation conducted by assessor or by individual or loved one

  • Goal: determine that factors that are influencing target behaviors

  • The ABCs of observation: antecedents, behavior, consequences

  • Self-monitoring: when an individual observes themself

  • May be informal or formal

  • The problem of reactivity: simple observing a behavior may cause it to change due to the individual’s knowledge of being observed

Psychological Testing

  • Specific tools for assessment of cognition, behavior, and emotion

  • Include specialized areas like personality and intelligence

  • Projective tests: project aspects of personality onto ambiguous test stimuli

    • Rooted in psychoanalytic tradition

    • Used to assess unconscious processes

    • Require high degree of inference in scoring and interpretation

  • Objective tests: tests stimuli are less ambiguous

    • Rooted in empirical tradition

    • Requires minimal clinical inference in scoring and interpretation

  • Personality tests

    • Minnesota Multiphase Personality Inventory (MMPI)

    • Extensive reliability, validity, and normative database

  • Intelligence tests: nature of intellectual functioning and IQ
