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.
