Classification Flashcards
What type of classification systems are the ICD and DSM?
Categorical - based on clinical descriptions
What is an operationalised approach to diagnosis?
Include the use of precise clinical description of disorders, together with predefined exclusion and inclusion criteria and details of the number and duration of symptoms required for diagnosis.
Benefits of operationalised approach?
Allows algorithm-based clinical diagnosis using intensity, duration of symptoms and impairment tests.
Such as a checklist
What are characteristic symptoms?
Those which are pertinent to the diagnosis
What are discriminating symptoms?
Necessary for diagnosis since they are not found in other disorders.
What helps facilitate application of operationalised diagnoses?
Computerised scoring systems such as OPCRIT for ICD 10
What is the atheoretical approach?
Diseases are described according to observed phenomenology; classification is not based on understanding what might be causing the disturbance.
No theory forms the basis of classification; only neutral observations
What is the descriptive approach?
Classifying illness based on what constitutes it rather than what causes it.
What makes the descriptive approach more rational?
Lack of pathogenetic knowledge of psych disorders
Which type of psychiatric illness has it been suggested that a dimensional system is needed?
Personality disorders
Advantages of dimensional approach?
More valid; emotinoal and cognitive states are on a continuum
Severity can be better indicated
Prevents need for comorbid diagnoses to be considered
Research using dimensional scales have greater powert o detect differences
Disadvantage of dimensional approach?
Clinical utility is questionable as dimensions cannot be directly mapped onto clinical decisions e.g. starting or stopping an intervention
Advantages of categorical approach
Easy to understand
Can be communicated with professionals
Existing knowledge base (presentation, course, prognosis) is based on these categories
Disadvantage of categorical approach
Poor validity - e.g. Psychosis not specified needed for atypical cases
What is hierarchical organisation of psych disorders based on?
Jasperian ideas - the ladder starts from organic disorders to substance use, psychosis, affective and neurosis up to personality issues.
What does hierarchical organisation of psych disorders mean?
If a disorder at the top explains the observed symptoms then diagnoses further down should not be entertained.
