Research On Effectiveness
There is clear evidence for the effectiveness of group psychotherapy for depression: a meta-analysis of 48 studies showed an overall effect size of 1.03, which is clinically highly significant. Similarly, a meta-analysis of five studies of group psychotherapy for adult sexual abuse survivors showed moderate to strong effect sizes, and there is also good evidence for effectiveness with chronic traumatic stress in war veterans. There is less robust evidence of good outcomes for patients with borderline personality disorder, with some studies showing only small to moderate effect sizes. The authors comment that these poor outcomes might reflect a need for additional support for some patients, in addition to the group therapy. This is borne out by the impressive results obtained using Mentalization based treatment, a model that combines dynamic group psychotherapy with individual psychotherapy and case management. Most outcome research is carried out using time-limited therapy with diagnostically homogenous groups. However, long-term intensive interactional group psychotherapy assumes diverse and diagnostically heterogeneous group membership, and an open-ended time scale for therapy. Good outcomes have also been demonstrated for this form of group therapy. Group Therapy has been shown to be as or more effective than individual therapy for higher functioning adults (Gardenswartz, 2009, Los Angeles, CA). Clinical cases has shown that the combination of both individual and group therapy is most beneficial for such clients. (the "multiplicative" effect).
