Practical insights into the distribution and comparative perceived effectiveness of peer support training modalities across multiple U.S. states

Introduction: Peer support services for mental health and substance use recovery have expanded across the U.S. and internationally, with growing demand for Certified Peer Support Specialists (CPSS). Yet, limited evidence exists on which training modalities best support CPSS preparedness.Theory: This cross-sectional study is grounded in recovery-oriented practice and adult learning theory, emphasizing mutuality, lived experience, and experiential learning.Method: The primary outcome was self‑reported post‑training preparedness (six‑point Likert scale). The key predictor was training modality (synchronous virtual, in‑person, hybrid, asynchronous online). Demographic and professional variables served as covariates. Chi‑square tests assessed modality distribution, and general linear models with propensity score matching evaluated whether virtual synchronous training produced preparedness comparable to other modalities.Results: The sample (N = 668) was predominantly female (73%), White (72%), with an average age of 46 and four years of CPSS experience. In‑person training was most common (58%), followed by synchronous virtual (31%), hybrid (7%), and asynchronous online (4%; p<.001). No significant preparedness differences emerged across modalities, indicating virtual training is as effective as in‑person, hybrid, or online formats.Discussion: Findings support flexible, scalable training approaches for CPSS. Blended models combining online content with interactive practice may enhance skill development, strengthen certification pathways, and build a more equitable and prepared CPSS workforce.
