Peer recovery support services (PRSS) are increasingly being offered across diverse criminal justice settings to address opioid abuse and achieve positive outcomes. The power and potential of PRSS come from the unique roles that peers play, promoting both hope and pragmatic steps for change. This webinar identifies common values that are the foundation for PRSS, regardless of the setting; defines the variety of roles that peers play across the sequential intercepts—and how programs can ensure that the roles are appropriate for the settings; outlines the core elements of successful PRSS programs at different intercepts; and describes approaches to training and supervision that prepare peers to effectively carry out their roles.
