The Thriving in Recovery Project proposes to expand peer recovery support services by engaging, educating, activating, and supporting volunteer peers in Chester and Montgomery Counties in Southeast Pennsylvania to deliver an array of peer recovery support services to individuals and families seeking to access and sustain recovery. The project will serve all populations in terms of race, ethnicity, language, gender identity, sexual orientation, and socioeconomic status, but will focus on the needs of young people ages 25 and under and their families. Over the three year project period, 155 peer volunteers will be recruited, trained, and supervised to provide a comprehensive array of peer recovery support services to 600 individuals and family members in need of support. The design and selection of project activities will be informed by community assessments, peer leadership councils, recovery community members, and those seeking to access recovery. Services to be offered will aim to support long-term holistic recovery management in the community and will address recovery domains of health, home, purpose, and community. Services will include: peer mentoring coaching, recovery planning, recovery check-ups, educational and social support groups, substance-free socialization activities, health and wellness linkages and services, physical health and fitness activities, employment and education related training, connections to housing and housing supports, linkages to medication-assisted treatment, support for specific groups (i.e., gender, pathway), and family education and mentoring. This project aims to mobilize and build recovery community capacity and positively impact the lives of individuals and families by having positive impacts on rates of abstinence from substances, safe and stable housing, criminal justice system involvement, education/training enrollment, employment, mental health symptoms, social connectedness, recovery capital, and quality of life.
