In the past two decades, numerous meta-analyses have been published that examine the question of psychotherapy equivalence. Hunsley and Di Giulio (2002) critically reviewed this literature and concluded that there was abundant evidence that the Dodo bird verdict of equivalence across psychotherapies is false. In this article, we summarize and update Hunsley and Di Giulio's (2002) review of recent meta-analyses and comparative treatment studies relevant to this question. Taken together, the empirical evidence clearly indicates that psychotherapy nonequivalence is the rule, not the exception. We discuss these findings and their implications for psychological research and practice. (Contains 1 table.)
