RecruitingBehavioural interventionExpanding the Youth Opioid Recovery Support (YORS) Intervention for MOUD Adherence to Adolescents With OUDDespite rising rates of fatal opioid overdoses in the United States, adolescents with OUD are far less likely than adults to receive and be retained on medication for opioid use disorder (MOUD). The multicomponent Youth Opioid Recovery Support (YORS) intervention for young adults seeks to increase adherence to extended-release MOUD and reduce opioid relapse through family involvement, assertive outreach, low-barrier access to MOUD, and contingency management. By expanding investigations of the evidence based YORS intervention to adolescents, especially those on sublingual buprenorphine, this project will significantly contribute to our knowledge base of practical strategies to address the opioid crisis in youth.
