Diagnostic reliability

Diagnostic reliability

In medicine and psychology, diagnostic reliability refers to the ability of a diagnostic tool, typically symptoms, to predict an illness or disorder. It is a direct application of the notion of statistical reliability. Since the etiology of most psychiatric disorders is not known, the most common measure of diagnostic reliability in psychiatry and clinical psychology is interrater agreement; this may be also be used for medical conditions of known etiology if no other tests are available, e.g. in Alzheimer's disease.
