Synthesis: The committee judged the overall body of evidence regarding group therapy formats to be low quality to inform a conclusion regarding efficacy because of the lack of well-designed studies comparing group and individual formats and including appropriate controls. The committee is uncertain about the presence of an effect, and believes that future well-designed studies will have an important impact on confidence in the effect and the size of the effect.
