The objective is to compare the accuracy, costs, and cost-effectiveness of three fidelity measurement methods to assess fidelity to cognitive-behavioral therapy for youth. The investigators will randomize 135 therapists, implementing cognitive-behavioral therapy, to 3 conditions: self-report, chart stimulated recall, and behavioral rehearsal (N = 45 for each group). To calculate the outcomes of interest, each condition will be compared to the gold-standard fidelity measurement method, direct observation.
