The studies identified suggest that group psychotherapy may be beneficial in reducing depression scores in the short term relative to no-psychotherapy controls however the benefits may not persist with longer term follow up. No conclusions can be drawn on the impact on functioning, HRQL, or hospitalization.
In patients with bipolar disease, data from 5 reports (4 studies) was found. The limited data suggests that group psychotherapy may reduce the number of recurrences compared to non-structured group therapy. No conclusions can be drawn on the impact on HRQL.
There were differences in the patient populations included in the RCTs, and selecting the patient population suitable for group therapy may be a consideration for decision makers. In addition, compliance with therapy and details such as appropriate length of treatment may also be a factor to consider when deciding about the use of group therapy for patients with mood disorders.
