Peer support services are delivered by individuals who have common life experiences with the people they are serving. People with mental and/or substance abuse disorders have a unique capacity to help each other based on a shared affiliation, and a deep understanding of this experience. In self-help and mutual support, people offer encouragement, strength and hope to their peers, which allows for personal growth, wellness-promotion, and recovery.

Peers also provide assistance that promotes a sense of belonging within the community. The ability to contribute to and enjoy one’s community is key to recovery and well-being. Another critical component that peers provide is the development of self-efficacy through role modeling and assisting peers with ongoing recovery through mastery of experiences and finding meaning, purpose, and social connections in their lives.
