Introduction: Community Health Workers/Promotores de Salud (CHW/Ps) are trusted messengers embedded in their communities who bridge gaps in access to care, address misinformation, and promote health through culturally tailored education and outreach. The Methods: This 12-h, five-part training was developed collaboratively and delivered by experienced CHW/Ps. The curriculum included interactive components such as role-playing, IRB simulations, and the design of community-relevant research projects. The program was evaluated using a mixed-methods approach, including pre- and post-training surveys, satisfaction surveys, and 3- and 12-month follow-ups. Results: Between March and September 2023, 128 CHW/Ps completed the training; 103 (80.5%) completed the 12-month follow-up. Most participants identified as Latino/Hispanic (93%) and female (96%). Quantitative findings assessed knowledge gain (46.8% increase), attitudes toward research (49.1% reported an increased likelihood of research participation post-training), self-efficacy in research communication (overall average of 8 out of 10), and application of training in community settings (53.9% reported referring people directly to research studies). Qualitative findings highlighted increased understanding of research ethics, community impact, the importance of participation in research, and persistent barriers to participation such as mistrust and misinformation.
