Abstract

Abstract: The addition of group psychotherapy as a specialty by the APA in 2018 creates a need for rigorous empirical reviews of group treatments for specific disorders. We conducted a meta-analysis of randomized controlled trials (RCTs) that tested the effect of group psychotherapy for mood disorders, including depression and bipolar disorder, at posttreatment and follow-up time-points, as well as rates of recovery and attrition. Major databases were searched for RCTs of group treatment for depression and bipolar disorder published from 1990 to 2018, which identified 42 studies across both disorders. Random effects meta-analyses indicated that group therapy for depression produced superior outcomes compared to waitlist control (WLC) and treatment as usual (TAU) and equivalent outcomes to medication. Similarly, group therapy for bipolar disorder produced superior outcomes to TAU. Analyses of recovery rates were conducted for depression, producing similar results to the main outcome analyses. Rates of attrition did not differ between group and comparison conditions for either disorder. These findings support group therapy for treating depression and bipolar disorder, although further research is needed comparing group treatment for bipolar disorder to medication.
