Follow-up study on borderline versus nonborderline personality disorders.

Using a semi-structured interview, 18 DSM-III borderline personality disorder (BPD) patients and 17 other (nonborderline) personality disorder (OPD) patients were compared blind 4 1/2 years after their index discharge. Although significantly younger and mostly single, BPD patients did not differ from OPD patients in the degree of overall psychopathology or in the level of psychosocial functioning and adjustment. They do not seem to represent a particularly severe personality disorder group. Those characteristics differentiating BPD patients from affective disorders and schizophrenia may be nonspecific regarding other personality disorder types. As such, more attention should be paid to cases of OPD in the future.
