Clinical Assessment and Diagnosis
Chapter 3
Abnormal Psychology
Clinical Assessment
Protocols used for evaluation and measurement
Assessing/diagnosing psychological disorders
Getting Started
What brings the client to the provider?
Discussion of the presenting problem and the client’s history
Concepts in Assessment
Reliability: the consistency of measurement
Validity: does it measure what it is meant to measure?
Standardization: comparing individuals with similar persons; asking questions in a consistent manner
The Clinical Interview
Current and past behavior
Emotions and attitudes
A detailed history The presenting
problem Significant life events
Childhood information and family history
Sexual development Religious
beliefs/cultural background
Educational history
The Mental Status Exam
1. Appearance and Behavior- motor behavior, movements
2. Thought process- rate/flow of speech; coherence; any evidence of delusions/hallucinations?
3. Mood and Affect- what is the mood and is it consistent? What is affect like and is it appropriate?
The Mental Status Exam
Intellectual functioning: vocabulary, use of language; general sense of cognitive abilities
Sensorium: Awareness of immediate surroundings; Oriented x3? (Person, place, time)
Issues to Consider
Is the client presenting the central issues? Are there other issues the client sees as unimportant?
Establishing rapport
Confidentiality: Scope and limitations
Other Clinical Interviews
Interviews or instruments specific to a particular disorder or concern: to learn the specific symptoms and their severity
Anxiety Disorders Interview Schedule- questions specific to compulsions and obsessions
Eating Disorder interviews/scales
Physical Exam
Physical problems may mimic psychological disorders
Thyroid issues
Brain lesions/tumors
Dementia
Drug induced conditions
Behavioral Assessments
Observing the client in specific contexts, in real life settings or simulated situations
Asking others to fill out behavior “checklists”
Often used with children: school and home visits
Self-Monitoring
Clients may be asked to keep a log of their thoughts/behaviors
When the behaviors occur in private
To note frequency, severity, and “triggers”; for self-reflection
Overview of Psychological Tests
Projective Tests
Personality Inventories
Intelligence Tests
Neuropsychological Tests
Projective Tests
Client “projects” thoughts and feelings- to reveal unconscious thoughts
Rorschach (ink blot test)
Thematic Apperception Test (TAT)
Critique: limited reliability/validity; not directly linked to the process of diagnosis
Personality Inventories
Comparing an individual’s score with the pattern of responses of those with diagnosed psychological conditions
MMPI: Minnesota Multiphasic Personality Inventory
567 true/false questions
MMPI
Sample Questions: I often think I’m being followed I am often happy for no reasonSometimes I get so mad I want to swear I sometimes throw up after mealsEvil spirits possess me at times
MMPI: Scales
Clinical Scales: 1: Hypochondriasis 2: Depression 3: Hysteria (Conversion) 4: Psychopathic Deviant 5: Masculinity/Femininity 6: Paranoia 7: Psychastenia (Anxiety) 8: Schizophrenia 9: Hypomania 0: Social Introversion
Lie Scale; Infrequency Scale (to detect
random answers); Defensiveness Scale
MMPI
Results in a “code type”
Looking at answers left blank
Excellent reliability, good validity
Neuropsychological Tests
NeuroimagingCAT scans/MRI: to assess brain damage
and to look at the structures of the brain
PET scans: the functioning/activity of the brain
EEG: brain waves
Issues in Diagnosis
Diagnostic and Statistical Manual
Reliability/Validity
Some diagnoses have greater reliability/validity than others
Personality Disorders tend to have lower reliability
Diagnostic and Statistical Manual
I and II were not widely used; lacked precision, were unscientific, and had little reliability
DSM III: 1980: more atheoretical; more precise descriptions; reliability/validity studies
Axes 1-5
Five “Axes” or Dimensions
Axis I: The DisorderAxis 2: Personality Disorder/MRAxis 3: Medical ConditionsAxis 4: Problems: Psychosocial &
EnvironmentalAxis 5: Global Assessment of Functioning
(Scale)
Critique of the DSM
Culturally sensitive?
Stigma of labels
“Fuzzy” categories and co-morbidity
Categories based more on history than current science? (Kraeplin’s dichotomy)
DSM-V
In progress
Various workgroups: clinicians and researchers
