Discriminating borderline personality disorder from other axis II disorders.

Abstract

The authors used the Revised Diagnostic Interview for Borderline Patients to assess 22 clinical features of 120 patients with borderline personality disorder and 103 control subjects with other axis II disorders. Four of the 22 features were common in but nondiscriminating for borderline disorder, 11 were discriminating for but nonspecific to borderline disorder, and seven were more specific to borderline disorder. The authors conclude that many clinical features thought to be indicative of borderline disorder are better viewed as personality disorder traits and that the seven more specific features, alone or in conjunction with one another, may be particularly useful markers for borderline personality disorder.
