Cognitive-behavioral group therapy for heterogeneous anxiety and mood disorders in a psychiatric hospital outpatient clinic

Recent literature has shown that group cognitive-behavioral therapy (CBT) is effective for individuals with heterogeneous anxiety disorders. However, these studies have used a narrow range of outcome measures, and have not included global measures such as quality of life. In addition, heterogeneous mood disorders have not been well researched. The aim of this study was to replicate and extend on previous studies by assessing the effectiveness of group CBT treatment programs designed for use with heterogeneous anxiety or depressive disorders. Global outcome measures of quality of life and social functioning were assessed in addition to outcome measures of anxiety and mood symptoms. There were 173 patients who completed either group CBT for anxiety disorders or for depressive disorders. Symptom measures and quality of life measures were used to determine treatment effectiveness. Results demonstrated that the treatments were effective in reducing overall symptom severity and improving quality of life. Treatment gains were maintained to 12 month follow-up. However, the degree of change was considerably lower than that found in comparable trials with diagnostically homogenous samples. Overall, group CBT for heterogeneous diagnostic populations was effective but requires further investigation and refinement
