This document summarizes a study that examined 17 meta-analyses comparing the outcomes of different active psychotherapies to each other. The analyses found an average small and non-significant effect size of 0.20 between therapies, confirming Rosenzweig's 1936 hypothesis that different psychotherapies would have only small differences in outcomes due to common factors. When accounting for researcher allegiance, the differences were even smaller, further supporting the "Dodo bird verdict" that all psychotherapies are similarly effective.
