Child and adolescent psychotherapy in research and practice contexts: Review of the evidence and suggestions for improving the field

  • John R. Weisz
  • Amanda L. Jensen


The body of evidence on child and adolescent psychotherapy outcomes has now grown to more than 500 studies. Here we summarize key findings, focusing on effectiveness and efficacy research. Research is sparse on the effectiveness of treatment in everyday practice, but available evidence suggests little benefit. By contrast, extensive research on efficacy of structured treatments administered under controlled conditions shows very substantial evidence of benefit. We note several specific treatments for which evidence is encouraging, and we offer suggestions for future research. Particularly important will be research on treatment models most often used in practice settings, tests of outcome mediators and moderators, tests employing a broadened range of treatment delivery models, and research bridging the gap between lab-tested treatments and the conditions of real-world practice.
