title: Intensive Quality Assurance of Therapist Adherence to Behavioral Interventions for Adolescent Substance Use Problems.
abstract: This study was a crosscultural replication of a study that investigated therapist adherence to behavioral interventions as a result of an intensive quality assurance system which was integrated into Multisystemic Therapy. Thirty-three therapists and eight supervisors participated in the study and were block randomized to either an Intensive Quality Assurance or a Workshop Only condition. Twenty-one of these therapists treated 41 cannabis-abusing adolescents and their families. Therapist adherence and youth drug screens were collected during a five-month baseline period prior to the workshop on contingency management and during 12 months post workshop. The results replicated the previous finding that therapist adherence to the cognitive-behavioral interventions, but not to contingency management, showed a strong positive difference in trend in favor of the intensive quality assurance condition. While the clinical impact of such quality assurance may be delayed and remains to be demonstrated, cannabis abstinence increased as a function of time in therapy, and was more likely with stronger therapy adherence to contingency management, but did not differ across quality assurance interventions.
