Abstract
Adolescents and young adults in the legal system (AYALS) are at high risk for opioid use disorder (OUD). Effective, efficient interventions to prevent OUD that support youth as they transition to the community are needed. The Positive Outcomes through Supported Transition intervention trial is designed to identify the optimal intensity and sequence of behavioral skills and case management components for OUD prevention. This sequential, multiple assignment randomized trial addresses three research questions: 1.whether to begin with a high-intensity, broad-scope intervention (Enhanced Adolescent Community Reinforcement Approach; E-ACRA) or a lower intensity intervention (Assertive Community Support; ACS), 2. whether to continue with E-ACRA or step-down to ACS after release, and 3. whether to step-up to E-ACRA or continue ACS for youth reporting problematic substance use after release. Youth committed to state custody will be recruited prior to their release and randomized to E-ACRA or ACS. At five weeks post-release, E-ACRA participants will be re-randomized to E-ACRA or ACS. ACS participants reporting problematic substance use at five weeks will be re-randomized to E-ACRA or ACS. Primary analyses will test the effects of initial intervention (E-ACRA vs. ACS); secondary analyses will test the effects of second-stage interventions. Cost-effectiveness analysis will determine whether the additional resources deployed to E-ACRA are justified economically by the outcomes achieved. Prevention is critical for this population. High-intensity interventions can be burdensome for participants (and agencies) and costly to deliver. This study examines how best to sequence high and low intensity interventions to maximize beneficial outcomes for the most youth. This study's design was pre-registered with clinicaltrials.gov (NCT04901312).
