The goal of this randomized clinical trial is to learn if a brief family-based intervention in effective in reducing cannabis use and delinquency in youth participating in juvenile diversion. The main questions it aims to answer are: Hypothesis 1: the intervention will be (a) feasible, as evidenced by enrollment rates (\> 80%), follow-up rates (\> 80%), and withdrawal rates (\< 20%); and (b) acceptable, as evidenced by \> 80% of treatment evaluation ratings in the highest two Likert rating categories and positive exit interview feedback. Hypothesis 2: those parents in the experimental condition, as compared to the active comparison psychoeducation condition, will evidence greater improvement over time in the hypothesized family-level mechanisms proposed in the intervention (i.e., parenting practices and parent well-being) as well as in youth-level outcomes, including cannabis use, recidivism, and HIV/STI risk. Researchers will compare the family-based treatment to parenting psychoeducation. Caregiver and youth participants will complete measures relevant to primary outcomes and putative mechanisms at baseline, 3-month, and 6-month follow-ups.
