diagnosis
“from a categorical perspective is defined by rules that outline how many and what features of a mental disorder must be present.”
dimensional vs categorical approach
Dimensional
Psychological distress varies along a continuum from
none to extreme, “clinically severe”
All people lie somewhere along this continuum Mental illness is just a variation in degree of
symptoms
Categorical
Psychological disorders are “all or none”—either you
have one or you don’t
Derived from the medical model
How do we know when someone is in psychological distress and/or has a clinically
severe disorder?
Methods of Assessment (Psychological)
Interview (Unstructured, Semi-structured, Structured) Intelligence Tests/Neuropsychological Tests Self-Report Questionnaires
Measures of global personality Measures of specific problems (and/or positive states)
Self-Monitoring Behavioral Observations Projective Tests
Methods of Assessment (Biological)
Neuroimaging (Functional MRIs, PET Scans, etc.) Neurochemical Assessment (Detect neurotransmitters from blood, urine, spinal fluid draws) Psychophysiological Assessment (heart rate/EKG, muscle tension/EMG, sweating/GSR
self report
Client’s retrospective reports of their own
functioning
Indirect measures
Subject to memory bias Subject to social desirability
Clinical Interviews
Necessary starting point that suggests what other types of
measures might be appropriate
Unstructured Structured
Self-Report Questionnaires Self-Ratings
beck depression inventory
Measures cognitive, affective, and somatic symptoms of depression consistent with descriptions in the psychiatric literature Items based on clinical observations and patient symptom reports (atheoretical) High scores in college students could mean overall adjustment problems vs. clinical depression
Psychometric Properties Internal Consistency Ranged from .80 to .90 Test-Retest Reliability Ranged from .48 to .86 in psychiatric populations Was .90 over 2 week among 200 college undergraduates Construct Validity Correlates…. .61 with MMPI Depression Scale .76 with SCLR90-R Scale .66 with Hamilton Depression Scale
self ratings
Subjective Units of Distress (SUDS)
Useful for Anxiety Disorders On a scale of 0-100, how anxious are you right
now?
Typically used in contrived situations
Imaginal, In Vivo, Virtual Reality Exposure
syndrome
“A group of emotional, cognitive, or behavioral symptoms, called a syndrome, that occur within a person.”
self monitoring
The client records the frequency, duration,
intensity, description of events as they happen or as close to that time as possible (e.g. end of the day)
Antecedent, Behavior Consequences Antecedent Belief, Behavior, Consequences
Advantages Does not suffer from recall problems--not retrospective Can provide ongoing data Convenient relative to behavioral observations Provides more complete information than outside observer Thoughts I’m going to fail! Private Situations Sexual Dysfunctions
Disadvantages More time-consuming than questionnaires Reactivity effects Paying attention to behavior and recording it may alter the naturally occurring behavior
behavioral assesment
The therapist records the frequency, duration,
intensity of overt behaviors as they happen or as close to that time as possible
Natural situation or controlled/contrived situation Videotape for later coding Time-consuming and expensive Behavioral reactivity (observation changes client
behavior)
Intelligence test
Wechsler Adult (or Child) Intelligence
Scale
Full-Scale,Verbal& Performance
(Spatial Reasoning) IQ
Neuropsychological Tests
Halstead-Reitan BatteryIndirect measure of brain functioning Assesses many cognitive and behavioral functions Used to make differential diagnoses between cognitive disorders and mood, anxiety, psychotic disorders
Neuroimaging
CT Scan-structural abnormalities MRI-structural abnormalities fMRI-functional abnormalities PET scan-structural and functional
Neurochemical Assessment
Neurotrasmitter metabolites from urine,
blood, spinal fluid (low serotonin levels, high dopamine levels)
psycho-physiological measures
Examining bodily changes associated with
various psychological states via electronic
devices
Primarily used to detect stress, anxiety, and sexual
arousal
DSM-V Cultural Formulation
Cultural identity of the client
Cultural ideas of distress
Cultural factors related to the social environment
Cultural influences on the relationship between
the client and the mental health professional
Overall cultural assessment
Reliability
Is your measure consistent?
Across time Among items Between observers
Validity
Does your measure assess what it’s supposed to
Test-retest reliability
Consistency of test scores or diagnoses across some period of time
Interrater reliability
Agreement between two or more raters or judges about level of a trait or presence/absence of a feature or diagnosis
Internal consistency reliability
Relationship among test items that measure the same variabl
Content validity
How well test or interview items adequately measure various aspects of a variable, construct, or diagnosis
Predictive validity
How well test scores or diagnoses predict and correlate with behavior or test scores that are observed or obtained at some future point
Concurrent validity
How well test scores or diagnoses correlate with a related but independent set of test scores or behaviors
Construct validit
How well test scores or diagnoses correlate with other measures or behaviors in a logical and theoretically consistent way
“Objective personality measures”
“involve administering a standard set of questions or statements to which a person responds using set options.”
projective tests
“such as the Rorschach and TAT rely on the assumption that people project their needs, conflicts, and personality when responding to ambiguous stimuli.”
