The evidence from the included studies suggests that group CBT may be an effective treatment approach to reduce anxiety and symptoms associated with anxiety disorders. No conclusions can be made regarding the effectiveness of group therapy on hospitalization and quality of life given that no evidence was reported in the identified literature.
The majority of the studies included a sample population that had a mix of patients with anxiety disorders. This limits the conclusions that can be made regarding specific anxiety disorders. Several of the studies recommended that further research be conducted to confirm findings.
The choice of setting, the method of assessment, the approach to deal with compliance, the availability of trained practitioners to deliver group therapy, and the specific details of the treatment (length of time, assessment tools, or group therapy intervention) may wish to be considered when deciding whether to use group therapy for the treatment of patients with anxiety disorders.
