Abstract

A number of diagnostic instruments are currently in use by researchers and clinicians interested in differential diagnosis. The Schedule for Affective Disorders and Schizophrenia (SADS) and the Research Diagnostic Criteria (RDC) have been demonstrated to greatly increase agreement among diagnosticians. Two investigations were conducted to examine the reliability of an abbreviated form of the full SADS (sads- c). A total of 120 nonparanoid and paranoid schizophrenic, bipolar manic and unipolar depressed patients and 26 normal subjects were interviewed using the sads- c and a number of other diagnostic instruments. Results of both studies suggest that the sads- c is a reliable brief rating instrument capable of differentiating among psychopathological groups. Symptom subscales of the sads- c were found to demonstrate convergent and divergent validity as determined by correlations with the remaining diagnostic instruments.
