Approaches to classification Flashcards
Approach to classification which uses precise clinical descriptions of disorders, with exclusion and inclusion criteria
Operationalised approach
Symptoms which are pertinent to a diagnosis
Characteristic symptoms
Symptoms which are necessary for a diagnosis
Discriminating symptoms
Symptoms which strongly favour one diagnosis
Pathognomic symptoms
Approach to classification where diseases are described according to their observed characteristics, not any theory of what might have caused the symptoms
Atheoretical approach
Approach which labels an individual as either meeting or not meeting the diagnostic criteria
Categorical approach
Approach which uses a continuum from high to low, along which a measurement is made
Dimensional approach
Approach to classification which is argued as having poor validity as it need to include criteria such as psychosis - not otherwise specified
Categorical approach
Approach to classification which is said to be more useful in describing emotional and cognitive states as many exist without a clear cut-off point between being ill and well
Dimensional approach
Approach to classification which has been argued as less useful as it is difficult to map to interventions to monitor response
Dimensional approach
Traditional hierarchy for mental health disorders, from top to bottom
Organic disorders Substance issues Psychosis Affective and neurotic disorders Personality issues
The idea that if a disorder further up the hierarchy can explain the symptoms, a disorder further down should not be diagnosed
Hierarchical organisation
Example of hierarchical organisation
E.g. a patient with dementia who experiences visual hallucinations which started after their cognitive issues would not also be diagnosed with a psychotic disorder
The idea that in a hierarchical organisation disorders can manifest as disorders lower down the hierarchy but not further up
Non-reflexive
