Background and Aims: Although medications for opioid use disorder (OUD), including extended‐release naltrexone (XR‐NTX), have demonstrated effectiveness, adherence is often low. We tested the preliminary efficacy of youth opioid recovery support (YORS), a multi‐component intervention designed to improve engagement and medication adherence for young adults with OUD. Design: Single‐site randomized controlled trial with 24‐week follow‐up. Setting: Community substance use disorder treatment program in Baltimore, MD, USA.
