The JEAP Initiative will advance research on the efficacy/effectiveness of peer recovery supports and recovery residences for public-system involved emerging adults and justice-involved adults with opioid use disorders and medication assisted treatment experience through ambitious but achievable goals: (1) identify priority areas of research via engaging individuals in recovery and providers/payors, (2) grow the field of skilled early career investigators focused on this research, (3) provide seed funds and guidance to produce preliminary studies for NIH funding, and (4) conduct dissemination and outreach to the larger field. With these aims, the JEAP Initiative is poised to be a catalyst that provokes rapid expansion in the number of skilled investigators and high-quality research tackling this critical public health issue.
