The authors compared the reliability of two methods of distinguishing
borderline personality disorder--DSM-III and the Diagnostic Interview for
Borderline Patients. The reference group, outpatients with other
personality disorders and without major axis I pathology, was more
difficult to distinguish from the patients with borderline personality
disorder than such groups used in previous samples. The sensitivity and
specificity of the Diagnostic Interview for Borderline Patients were
calculated, with DSM-III used as a criterion. The findings confirm
considerable overlap between borderline and schizotypal personality
disorders, more impairment in functioning in borderline patients than in
those with other personality disorders, and the high reliability with which
borderline personality disorder can be diagnosed.Abstract Teaser
