RecruitingBehavioural interventionTesting the Effectiveness and Implementation of a Meditation App for Youth in the Legal SystemThe goals of this hybrid type 2 randomized controlled trial (RCT) are to evaluate the effectiveness and individual-level implementation of a 1-month app-based meditation program with youth on probation in Cook County, IL. The primary questions it is designed to answer are: 1. Is the meditation app associated with improvements in behavioral health outcomes including cannabis use problems? 2. Do improvements in emotion regulation appear to mediate the effects of the meditation app on these behavioral health outcomes? 3. Will youth adequately adhere to the meditation app?
