CHAPTER 2: Assessment, Classification, and Treatment of Abnormal Behaviour Flashcards
Reliability
consistency of measuring instrument
Interrater reliability
when assessments from different researchers/evaluators are consistent
Internal consistency
when different items within an assessment produce similar results
Temporal stability
stability of the content of reports across time
Validity
degree to which test measures traits or constructs that it purports to measure
Content validity
extent to which a measure represents the entire domain of a given construct
Criterion validity
how well does it predict an established standard of outcome
Construct validity
extent to which the measure behaves in a way consistent with hypotheses
Unstructured clinical interview
interviewers determine which questions to ask
Structured clinical interview
interviewer obtains clinical information from a client by asking standard series of questions (highest reliability and consistency)
Semi-structured clinical interview
interviewers are guided by general outline, but are free to modify the order and branch off in other directions
Intelligence quotient (IQ)
IQ = mental age / chronological age x 100
Self-report tests
objective personality test, which may reflect underlying reponse biases
Objective tests
limited, specified range of response options or answers so they can be scored objectively
Forced-choice formats
method of structuring test questions that require respondents to select among set number of answers
Projective tests
personality test that offers no clear, specified answer, obtained from ambiguous stimuli (inkblots)
Bender-Gestalt II
clients are asked to copy geometric designs with distortions or rotations being signs of brain damage
asked to produce figures from memory to test memory
Halstead-Reitan neurospychological battery
contains tests that measure perceptual, intellectual and motor skills
Luria-Nebraska battery
reveals patterns of deficit that suggest particular sites of brain damage
tactile, kinesthetic, spacial, motor, and auditory skills
Functional analysis
analysis of problems in relation to antecedents, or stimulus cues that trigger it, and the reinforcements that maintain it
Self-monitoring
used to gather data regarding rate of occurence of target behaviour before treatment (baseline)
Analogue measures
stimulate settings in which behaviour naturally take place, but in laboratory or controlled setting
Behavioural rating scales
checklist that provides information about frequency, intensity, and range of problem behaviours
Behavioural assessment
focuses on object recording and description of behaviour
Cognitive assessment
assessment of cognitions (thoughts, beliefs, attitudes)
Thought diaries
carry diaries to record dysfunctional thoughts as they arise
