Establishing treatment fidelity in evidence-based parent training programs for externalizing disorders in children and adolescents.

The current review evaluates the use of treatment fidelity strategies in evidence-based parent training programs for treating externalizing disorders. We used a broad framework for evaluating treatment fidelity developed by the National Institutes of Health Treatment Fidelity Workgroup that includes the aspects of treatment design, treatment delivery, training providers, and assessment of participant receipt of treatment and enactment of treatment skills. Sixty-five articles reporting outcome trials of evidence-based parent training programs met inclusion criteria and were coded for treatment fidelity strategies.
