Extensive meta-analytic evidence consistently indicates that participating in psychotherapy yields measurable mental health benefits, such as significant reductions in depression, anxiety, and distress across diverse populations.
The vast majority of the retrieved meta-analyses (papers 0, 1, 2, 3, 5, 6, 7, and 11) provide robust positive support showing that various forms of psychotherapy and psychosocial interventions successfully improve mental health outcomes compared to control groups. Paper 10 notes that one specific therapy (ACT) is not superior to other established psychotherapies, but this does not refute the broader claim that psychotherapy benefits individuals. Therefore, the evidence clearly supports the claim.
