Recovery Housing Peer Project is a research study whose purpose is to learn more about peers and house managers providing services within Maryland NARR Levels 2 and 3 recovery residences. We aim to better understand how peer roles are defined, training needs, organizational supports for peers, and impacts of peer work on peers' quality of life, employment, and 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 operators, or policy representatives. Participants will receive a $100 gift card for their time.
