R-HOPE is a research study aimed to better understand different aspects of peers working in Maryland substance use recovery residences. We hope to learn more about how peer roles are defined, training needs, organizational supports for peer, and impacts of peer work on peer recovery. Results from this study may be used to improve supports for peers and recovery residence service-delivery and policies. To learn this information, our team will be conducting interviews with representatives from the following groups: peer support workers or house managers, recovery residence administrators, or state policy representatives.
