Practitioner Review: Psychological treatments for children and adolescents with conduct disorder problems - a systematic review and meta-analysis.

Psychological treatments have a small effect in reducing parent-, teacher- and observer-rated CD problems in children and adolescents with clinical CD problems/diagnosis. There is not enough evidence to support one specific psychological treatment over another. Future studies should investigate the influence of participant characteristics (e.g. age of CD onset), use more homogeneous outcome measures and allow better evaluation of study quality. Many reports failed to provide detailed information to allow optimization of psychological treatment strategies.
