The present paper focuses on the strengths-based role of the wounded healer, as exemplified by current or released incarcerated people who desist from crime and recover through professional practice of peer support, in the community or in prison. The paper has two purposes. One is to review criminological approaches and models related to peer-based rehabilitation and to encompass them under a single term proposed here— Convict Therapy. The second is to review research on peer support programs currently implemented in in various countries, in a bid to discern their hallmarks and strengths. This to enrich and promote the discourse, research, and practice of this evolving field, and to offer new research directions for examining the effectiveness of peer support in the long run, for the aid providers, the recipients, and the community.
