Are complex psychotherapies more effective than biofeedback, progressive muscle relaxation, or both? A meta-analysis.

A meta-analysis of 26 studies was conducted to assess whether more complex forms of psychotherapy would be superior to control treatments of either biofeedback, progressive muscle relaxation, or both. Consistent with hypotheses, more complex treatments provided a small, significant improvement over biofeedback and progressive muscle relaxation (r = .09).
