Family and Adolescent Motivational Incentives for Leveraging Youth

Summary

Research has provided support for the efficacy of cognitive-behavioral and family interventions for adolescent substance use disorders (SUD), HIV-risk behaviors, and related problems. Despite support for these interventions, substantial heterogeneity in treatment outcomes and high relapse rates has been consistently found across studies. Such variability highlights the need for innovative strategies to broaden the impact and strengthen the durability of effects of adolescent substance abuse treatments. Over the past two decades, research has shown the positive effects of contingency management (CM) methods on reductions in substance use and other problem behaviors. When combined with evidence-based practices, emerging research suggests that CM integration may also be effective for adolescent substance abusers. The proposed Stage II efficacy trial examines the integration of CM with two empirically-supported interventions: group MET/CBT and FFT. By comparing two intervention modalities (group vs. family, the study provides a unique opportunity to examine the robustness of the effects of CM across established adolescent treatments, and to compare change mechanisms that may account for treatment outcomes. In the proposed research, substance abusing adolescents (n = 160) will be randomly assigned either to FFT or group MET/CBT. Random assignment will also be used to determine whether or not youth will receive a CM condition that provides incentives for abstinence (i.e., clean urine screens) and treatment participation. The primary aim of the study is to examine the efficacy of an integrated CM intervention for the two evidence-based treatments for adolescents, MET/CBT and FFT, compared to these treatments without CM on drug abuse abstinence (a) during treatment (i.e., speed of effects) and (b) at post-treatment follow-up assessments (i.e., durability of effects). A second aim of the study is to evaluate the effects of CM on hypothesized mediators of the intervention effects in the MET/CBT and the FFT conditions. The investigators anticipate that the CM conditions, compared to the nonCM conditions, are more likely to accelerate the adolescent's motivation (1) to achieve abstinence, to attend and participate in treatment, and to complete homework assignments. The investigators will also examine the effects of the interventions on HIV-risk behaviors and expect that CM will demonstrate the largest reductions in HIV-risk behaviors compared to the nonCM conditions.
