Wirksamkeit ambulanter Gruppenpsychotherapie in Deutschland: Ergebnisse der PAGE-Studie

Abstract

Summary Effectiveness of Outpatient Group Psychotherapy in Germany – Results of the PAGE-Study The PAGE study underlines the effectiveness of long-term psychodynamic and psychodra matic outpatient group therapies in a naturalistic setting. 40 experienced group therapists cooperated, and complete outcome data of 244 patients from psychodynamic groups and of 91 patients from psychodramatic groups (pre-post) were obtained. The effect sizes are consi derably high (ES PA = 1.33 and ES PD = 1.01) compared to internationally reported effect sizes of psychotherapeutic treatments. They highlight the importance of long-term therapeutic treatments with a severely and chronically disturbed clientele. A direct comparison between both approaches – psychodynamic and psychodramatic group therapy – is not possible due to significant differences in treatment lengths and patient demands. Approximately 2.000 treatment goals were obtained from all participating patients and provide information regarding the relationship between intrapsychic and interpersonal treatment goals of patients undergoing group psychotherapy.
