Examining the experiences of student peer support workers delivering care within post-secondary institutions

<b>Objective:</b> Despite experiencing exacerbation of mental health issues, post-secondary students may not seek help due to perceived stigma, overreliance on the self, or preference for nonprofessional supports - including peer support. This study aimed to understand peer support workers' (PSWs) perspectives regarding providing support for mental health concerns in post-secondary institutions. <b>Methods:</b> 41 PSWs were recruited from two post-secondary institutions. 17 semi-structured interviews and three focus groups were conducted. Themes were identified using a qualitative descriptive approach. <b>Results:</b> Three themes emerged: (1) diverse presentations and approaches to operationalizing peer support for mental health issues on campus exist; (2) peer support has core ingredients; (3) reasons why students access peer support extend beyond mental health crisis. <b>Conclusions:</b> An inclusive peer support approach to mental health is needed for post-secondary students. Considerations for implementation hinge on providing standardized, foundational training to prepare PSWs for the complex mental health issues that present across services.
