Using DSM axis II information to predict outcome in short-term individual psychotherapy.
The present study considered three methods of using DSM Axis II information to examine the effect of personality disorder on outcome in two forms of short-term, individual psychotherapy (interpretive and supportive). The first method involved examining whether the presence of any personality disorder influenced treatment outcome. The second method involved examining the effect of the number of personality disorders on outcome. The third involved examining outcome for specific personality disorders. The study found that a diagnosis of any personality disorder did not influence the outcome of therapy. In contrast, the number of personality disorders was significantly related to outcome at post-therapy and at 12-month follow-up. The findings indicated that a greater number of personality disorders was associated with less favorable outcome across both forms of therapy. This supports the notion that personality pathology is more severe when it involves a greater number of personality disorders. In an exploratory set of analyses, the study also found some evidence of differences in outcome for specific personality disorders.
