This pilot study evaluates the feasibility, usability, and acceptability of the Thrive Digital Peer Platform (TDPP), an online training system for Peer Recovery Support Specialists (PRSS). Twelve participants were enrolled to complete the full TDPP asynchronous curriculum, including self-paced modules, peer-led storytelling, and applied practice activities. The study aimed to assess participant engagement, satisfaction, and perceived relevance of the training to their work as peer supporters. This work represents the Phase I portion of a Fast Track SBIR funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA).

The Thrive Digital Peer Platform (TDPP) was developed to support the professionalization and skill development of Peer Recovery Support Specialists (PRSS) by providing an accessible, modular, and evidence-informed training experience. In this Phase I pilot, twelve PRSS participants were recruited to complete a series of interactive online learning modules aligned with the "Connect, Grow, Apply" (CGA) educational framework. Each module contained peer-led narratives, knowledge checks, and behavioral exercises grounded in real-world coaching scenarios.

Primary outcomes included system usability, satisfaction, and self-reported training relevance. Participants completed a post-training assessment and a brief exit interview to capture usability and acceptability ratings. The findings were used to refine content, improve onboarding, and establish readiness for a larger randomized controlled trial in Phase II.

This study did not include a control group. All participants received access to the full training experience and completed their participation within a defined study period. No follow-up or long-term monitoring was conducted.

This trial was conducted as the Phase I component of a Fast Track SBIR (R44AA030953) funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA).
