Diagnostic concordance between DSM-III, Feighner, and RDC.

The NIMH Diagnostic Interview Schedule was administered by psychiatrists to 216 individuals. The DSM-III, Feighner, and RDC diagnoses derived from the computerized interview results were then compared for eight psychiatric disorders. Rates of diagnostic concordance among the systems are given, and the causes of diagnostic discrepancies are discussed. Diagnostic concordance was highest for mania and alcoholism and lowest for schizophrenia and antisocial personality disorder. Implications of these findings and future research directions are discussed.
