COMORBIDITY OF DSM-III-R PERSONALITY-DISORDERS IN SCHIZOPHRENIC AND UNIPOLAR MOOD DISORDERS - A COMPARATIVE-STUDY

We investigated the overall prevalence and the differential comorbidit y of Diagnostic and Statistical Manual (DSM)-III-R personality disorde rs in 166 remitted or recovered patients with schizophrenic (n = 102) or unipolar mood disorder (n = 64). Over 60% of both patient groups me t the DSM-III-R criteria of at least one DSM-III-R personality disorde r as assessed by means of the Structured Clinical Interview for DSM-II I-R (SCID-II-R), receiving on average 3.1 personality diagnoses. Neith er DSM-III-R categories of personality disorders, nor scores on its th ree clusters A, B and C, nor total score on SCID-II-R differed signifi cantly across the two groups. In conclusion, DSM-III-R personality dis orders, although highly prevalent in schizophrenic and unipolar mood d isorders, lack any specificity with respect to these categories of men tal disorders.
