Interpersonal functioning or ability to mentalize. Outcome predictors in group psychotherapy

This paper investigates the predictive value of the psychological mindedness assessment procedure (PMAP) with respect to differential group therapy outcome using outpatient group therapies with patients suffering from somatoform disorders. Within the contextual framework of the mentalization theory the possible predictive power of the PMAP prior to indications for therapy is reflected. As the results of 50 patients from 6 therapy groups show high PMAP ratings prior to treatment onset predict group suitability of patients. This in turn is predictive for an emotional attunement of such patients during treatment, which is in itself a qualification for an emotional involvement with the group interactive process and therefore highly predictive. In contrast patients with a lower PMAP rating should be referred to groups where another treatment concept or technical attitude on the part of the group leader is realized. The shorter the therapy groups last the more homogeneous group composition should be regarding psychological functioning of patients prior to treatment onset (level of mentalization).
