Substance use approaches among peer support specialists in community mental health early psychosis programs

Substance use (SU) is common among adolescents and young adults, including those experiencing early psychosis. Coordinated Specialty Care (CSC), a community-based multidisciplinary team-based service model, is increasingly used to support people experiencing first-episode psychosis. In addition to prescribers, clinicians, and vocational specialists, CSC includes peer support specialists who use their own living/lived experience with mental health and treatment to engage and support young people with their recovery goals. Peer support is also foundational in SU recovery. However, little is known about how peer support specialists navigate client SU in CSC. The purpose of this article is to detail CSC peer support SU practice.

Informed by community-based participatory research methods, a PhD-level qualitative researcher and a former peer support specialist conducted virtual interviews with 20 CSC peer support specialists. A multidisciplinary team including researchers with lived mental health experiences thematically coded interview transcripts.

A spectrum of CSC peer support specialist SU responses emerged: (a) leverages lived SU experiences; (b) does not explore SU with clients; (c) shares client SU information with the CSC team; (d) educates, mentors, and advocates; (e) shares SU consequences and/or challenges substance use; (f) nonjudgmental, nondirective SU exploration; and (g) promotes harm reduction.

CSC peer specialist SU practice is influenced by several contextual tensions that must be better understood and addressed in future research to improve peer SU practice. Study findings speak to practice nuances that are helpful for CSC peer support training and supervision. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
