Set B

Confirmation-ary Bias

A clinical bias whereby clinicians ignore information that does not support their initial hyptheses or stereotypes and they interpret ambiguous information as supporting their hypotheses.

Cronbach's α

Statistical test used to assess the internal consistency of a questionnaire or inventory.

Contruct Validity

Independent evidence showing that a measure of a construct is related to other similar measures.

Disorder Spectrum

The frequency of comorbidity suggests that most disorders as defined by DSM may indeed not be independent discrete disorders, but may represent symptoms of a disorder spectrum that represents a higher-order categorical class of symptoms.

Ecological Momentary Assessment (EMA)

The use of diaries for self-observation or self-monitoring, perhaps by using an electronic diary or a palmtop computer.

Concurrent Validity

A measure of how highly correlated scores of one test are are with scores from other types of assessment that we know also measure that attribute.

Cultural Bias

The phenomenon of interpreting and judging phenomena in terms particular to one's own culture.

Diagnostic and Statistical Manual (DSM)

First published in 1952 by the American Psychiatric Association (APA), the DSM extended the World Health Organisation’s (WHO) International List of Causes of Death (ICD) classification system to include a more widely accepted section on mental disorders.
