Assessment, Classification, and Treatment of Abnormal Behaviour Flashcards
Assessment
Provides a wealth of information about a clients’ personality and cognitive functioning
Methods must be reliable and valid
Reliability
Internal consistency
Temporal stability
Interrater reliability
Validity
Content validity
Criterion validity
Construct validity
Sociocultural and Ethnic Factors in the Assessment of Abnormal Behaviour
Assessment techniques may be reliable and valid in one culture but not in another
Most diagnostic instruments consider culture but fail to provide adequate norms for different cultural and ethnic groups
Differences when interviews are conducted in a language other than the client’s mother tongue
The Clinical Interview
The most widely used method of assessment
Gather information about complaints, precipitating events, how the problem affects daily functioning
The Three Major Types of Clinical Interviews
Unstructured
Semi-structured
Structured
The Unstructured Interview
Interviewers determine which questions to ask rather than following a standard interview format
The Semi-structured Interview
Interview in which interviewers are guided by a general outline but are free to modify the order in which questions are asked and to branch off in other directions
The Structured Interview
Follows a preset series of questions in a particular order
Provides the highest level of reliability and consistency in reaching diagnostic judgements
Mental Status Examination
Structured clinical evaluation to determine various aspects of a client's mental functioning Evaluate: -appearance -mood, attention, perception, memory -orientation -level of awareness -judgement in making life decisions
What are the 5 P’s?
Presenting issues Precipitating factors -triggers Perpetuating factors -what keeps the problem going Predisposing factors -what led to these problems starting Protective factors -strengths
What is Intelligence?
Global capacity to understand the world and cope with its challenges
Traits associated with a successful performance on intelligence tests
Mental Age
Age equivalent that corresponds to the person’s level of intelligence, as measured by performance on the Stanford-Binet Intelligence Scale
Intelligence Quotient
IQ = MA/CAx100
The Wechsler Scales
Wechsler’s scales include both verbal and performance subtests
Verbal subsets generally require knowledge of verbal concepts
Performance subtests rely more on spatial relations skills
Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMP 1-2-R F)
Contains 338 true-false statements that assess personality
Used as a test of personality and assisting in the diagnosis of abnormal behaviour patterns
Contains validity scales to detect response biases
Objective Tests
Tests that allow a limited, specific range of response options or answers so that they can be scored objectively
Forced-choice Formats
Method of structuring test questions that require respondents to select among a set number of possible answers
The Rorschach Inkblot Test
A person’s responses to inkblots are used to reveal aspects of their personality
Evaluation of the Rorschach Inkblot Test
Lack of standard scoring procedures
Interpretation of a person’s responses is not objective
Depends on the subjective judgement of the examiner
The Thematic Apperception Test (TAT)
Consists of a series of cards depicting ambiguous scenes
Respondents are asked to construct stories about the cards
Assumed that their tales reflect their experiences and outlooks on life
Evaluation of the TAT
The client’s response may represent a reaction to stimulus cues rather than projections of their personality
Scoring and interpretation of the responses largely depends on the clinician’s subjective impressions
House Tree Person Test
Respondents draw a house, tree, and person
Represents one’s cognitive, emotional, and social functioning
Neuropsychological Assessment
Used to evaluate whether or not psychological problems reflect underlying neurological damage or brain defects
Bender Visual-Motor Gestalt Test
Respondents copy geometric designs and then are asked to redraw them from memory
If there is any damage this can be indicated by rotation of figures, distortions in shape, incorrect sizing
Luria-Nebraska Neuropsychological Battery (LNNB)
Reveals patterns of skill deficits that are suggestive of particular sites of brain damage
Halstead-Reitan Neuropsychological Battery (HRNB)
Permits the psychologist to observe patterns of results, and various patterns of performance are suggestive of certain kinds of brain defects, such as those occurring following a brain injury
Psychometric Approach
Used to identify and measure the reasonably stable traits in an individual’s personality that are believed to largely determine their behaviour
Behavioural Approach
Behaviour is primarily determined by environmental or situational factors, such as stimulus cues and reinforcements
Behavioural Assessment
Clinical assessment that focuses on the objective recording or description of problem behaviour rather than on inferences about personality traits
Behavioural Interview
Approach to clinical interviewing that focuses on relating problem behaviour to antecedent stimuli and reinforcement consequences
