A Nonrandomized Effectiveness Comparison of Broad-Spectrum Group CBT to Individual CBT for Depressed Outpatients in a Community Mental Health Setting

Abstract Controlled trials have established the efficacy of cognitive-behavior therapy (CBT) for depression. However, the relative effectiveness of individual versus group treatment formats in real-world settings is less well established. The current study evaluated the effectiveness of group CBT (...

Description
Summary:Abstract Controlled trials have established the efficacy of cognitive-behavior therapy (CBT) for depression. However, the relative effectiveness of individual versus group treatment formats in real-world settings is less well established. The current study evaluated the effectiveness of group CBT ( n = 157) compared to individual CBT ( n = 77) for depressed outpatients in a naturalistic setting. Symptom improvements for depression, anxiety, and quality of life were compared between treatment formats in intent-to-treat and completer analyses. Effect sizes and rates of recovery were examined. Results showed that both individual and group CBT were effective, even in the presence of high levels of comorbidity. Whereas individual CBT was associated with larger effect sizes and significantly higher rates of recovery, group CBT compared favorably to outcomes established by past research. A broad-spectrum group CBT program may be a viable treatment option when depression symptoms are less severe and when this format of treatment delivery is desirable.
