Chapter 5: Classification, Assessment & Intervention Flashcards
Classification/taxonomy
Major categories or dimensions of behavioural disorders
Diagnosis
Assigning a category of a classification system to an individual
Assesment
Evaluating individual’s to assist in the process of classification and diagnosis and also to act as intervention.
Category
Discrete grouping (ex: anxiety disorder)
Dimension
An attribute is continuous and can occur to various degrees
Interrater Reliability
Whether different diagnosticians use the same category to describe a person’s behaviour.
Test-retest reliability
Wether the use of a category is stable over some reasonable period of time.
Validity
Diagnosis should give further info on the:
- etiology of the disorder
- course of development the disorder is expected to take
- response to treatments
- additional clinical features of the problem.
Clinical utility
Classifications systems are judged based on how complete and useful it is.
APA: DSM (Diagnostic and statistical manual of mental disorders)
AKA: clinically derived classification - based on consensus of clinicians that certain characteristics occur together :
Top down approaches
Committees of experts propose
concepts of disorders and then choose diagnostic criteria for defining disorders.
It is from these criteria that the development of assessments and evaluations
proceed.
Categorical Approach
An idividual either HAS or does NOT have the disorder.
Difference between normal and pathological in a categorical approach is one ‘kind’ rather than one ‘degree’.
Distinctions can be made between qualitively different types of disorders.
Comorbidity : co-occurence
When an individual meets criteria for more than one disorder: simultaneous existence of two or more disorders in the same individual
Empirical approach to classification
Using statistical techniques to identify patterns of behavior that are interrelated.
Syndrome
Describes behaviour that tend to occur simultaneously together
Spectrum
Groups of disorders thought to hare certain psychological or biological qualities.
Dimension
Quantitative rather than qualitative approach to viewing disorders. Can be adressed using a cross-cutting assessment: adresses areas of clinical importance that are not necessary to the diagnosis of a disroder, but are iportant to the prognosis, treatment planning and treatment outcome.
Broadband syndromes
general clusters of behaviour or characteristic
Broadband syndrome: Internalizing
Internalizing: overcontrolled/
anxiety-withdrawal.
Descriptions include: anxious, shy, withdrawing, depressed.
