Change Mechanisms in Group Therapy: A Questionnaire to Measure Therapeutic Perspectives

Group therapy was shown to be an effective and economic intervention. To date few instruments exist to empirically assess mechanisms of therapeutic change in group therapy. The Group Therapy Process Questionnaire for Therapists (FEPiG-T) measuring change mechanisms in group therapy as viewed from the perspectives of therapists was developed and validated in this study based on the conceptualizations of Grawe,Yalom and Bordin and in reference to the previously developed measure for patients. The FEPiG-T subscales show good internal consistencies and small to large correlations with convergent measures. Subscales at beginning of therapy correlated with improvement of interpersonal problems over time. Further associations with symptom scales remained more vague. However, intersections with the established version for patients allow routinely implemented evaluation of the 2 perspectives in clinical practice, but inevitably need careful interpretation where the instruments differ in their factor structure.
