Peer research has emerged as a popular form of community-based research (CBR) where research projects include members of the target population who are trained to participate as co-researchers. The inclusion of community members in CBR through peer research initiatives is thought to enhance the quality of the data collected, allow for the expertise of lived experience to be incorporated over time, while promoting capacity building at the local level. Brenda Roche along with Sarah Flicker and Adrian Guta present Peer Research in Action in three parts: Models of Practice; Management, Support and Supervision; and, Ethical Issues.
