Summary:
An analysis of the studies which have been conducted with a new, increasingly popular, form of psychotherapy (acceptance and commitment therapy, ACT) is raising doubts on the specificity of the strategy. The results reveal that ACT is more effective than control conditions for several problem domains, but there is no evidence yet that ACT is more effective than established treatments.

An analysis of the studies which have been conducted with a new, increasingly popular, form of psychotherapy (Acceptance and Commitment Therapy) is raising doubts on the specificity of the strategy. The study has been published by a group of Dutch investigators headed by Prof. Emmelkamp in the current issue of Psychotherapy and Psychosomatics.

There are now a substantial number of controlled trials investigating the efficacy of acceptance and commitment therapy (ACT). This meta-analysis combined multiple well-controlled studies to help clarify the overall impact of ACT relative to waiting lists, psychological placebos, treatment as usual, and established therapies. A comprehensive literature search produced 18 randomized controlled trials (n = 917) that were included in the final analyses.

Effect size was computed with Hedges's g which can be interpreted with Cohen's convention of small (0.2), medium (0.5), and large (0.8) effects. There was a clear overall advantage of ACT compared to control conditions (effect size = 0.42). The average ACT-treated participant was more improved than 66% of the participants in the control conditions. Analyzed separately ACT was superior to waiting lists and psychological placebos (effect size = 0.68) and treatment as usual (effect size = 0.42).

However, ACT was not significantly more effective than established treatments (effect size = 0.18, p = 0.13). Also, ACT was not superior to control conditions for the distress problems (anxiety/depression: effect size = 0.03, p = 0.84).

The results reveal that ACT is more effective than control conditions for several problem domains, but there is no evidence yet that ACT is more effective than established treatments.
