Therapieeffekte mentalisierungsbasierter und psychodynamischer Gruppenpsychotherapie in einer randomisierten Tagesklinik-Studie

Abstract

Summary Mentalization Based Group Therapy and Psychodynamic Group Psychotherapy in a Randomized Day Clinic Study: Therapy Effects There is no evidence of efficacy of mentalization based group therapy (MBT-G) against widely distributed psychodynamic group therapy (PDGT). To prove if MBT-G is also a useful therapeutic concept for a heterogeneous patient group, we examined the efficacy of MBT-G in contrast to psychodynamic group therapy (PDGT) in a heterogeneous patient sample in a psychotherapeutic day clinic in a randomized process outcome study (N=211). The first results of completer analyses are shown. In sum in variance analysis there are high prepost- effects in symptom reduction (GSI/SCL) and interpersonal problems (IIP), middle effects in mentalization (LEAS, MASC), but no significant differences between the groups. Further analysis with depended t-tests show in scope of alexithymia (LEAS) middle effects in MBT-G and low effects in PDGT, whereas in social cognition (MASC) both have low treatment effects. The results can be interpreted that MBT-G in a heterogeneous population of a day clinic is not superior to PDGT, but supposedly tend to a higher improvement of mentalization of self (in contrast to other) as PDGT. In next step further analysis of diagnostic groups and mediator-moderator analysis of mentalization should enable to interpret the data in a differentiated way and to get more information for clinical use.
