[Multi-family group therapy in Germany]

Multi-family therapy, common group therapy with several families per one index patient, has been gaining popularity recently. This has occasioned an exploratory study of the status of implementation and common factors in all multi-family therapy programs in Germany. In a survey conducted across Germany, all providers of multi-family therapy interventions were requested to give a detailed description of their intervention. Quantitative data were analyzed with descriptive statistics, and verbal data were summarized categorically with qualitative content analysis. Of the 25 intervention programs examined 21 are directed at emotionally disturbed children and young people and their families; mainly with disturbances in social behavior. Over 4,000 families per year are treated in multi-family therapy, and five programs were systematically evaluated. MFT is characterized by systematically oriented group therapy methods. Those surveyed traced the effect of this form of intervention back to activating problems in the group, activating resources, changing perspective, learning models, experiencing self-efficacy, and the therapeutic relationship. Systematic studies of multi-family therapy in evaluations and in random controlled study designs are recommended.
