Interpretive and supportive forms of psychotherapy and patient personality variables.
A randomized clinical trial investigated the efficacy of interpretive and supportive forms of short-term individual psychotherapy and the interaction of each form with the patient's quality of object relations (QOR) and psychological mindedness (PM). The psychiatric outpatient sample included 144 therapy completers and 27 dropouts. Eight experienced therapists provided distinct forms of manual-guided therapy. Outcome was assessed by a comprehensive battery. The dropout rate was higher for interpretive therapy than for supportive therapy. Patients in both forms improved, but they did not differ on outcome from each other. A multivariate interaction effect indicated a direct relation between QOR and outcome for interpretive therapy and almost no relation for supportive therapy. A multivariate main effect indicated a direct relation between PM and outcome for both forms. The relevance of patient personality to outcome in different forms of therapy is addressed.
