A Metascientific Review of the Evidential Value of Acceptance and Commitment Therapy for Depression.

In the past three-and-a-half decades, nearly 500 randomized controlled trials (RCTs) have examined Acceptance and Commitment Therapy (ACT) for a range of health problems, including depression. However, emerging concerns regarding the replicability of scientific findings across psychology and mental health treatment outcome research highlight a need to re-examine the strength of evidence for treatment efficacy. Therefore, we conducted a metascientific review of the evidential value of ACT in treating depression.
