The Feasibility of Recruiting and Training Lay Leaders During Real-World Program Delivery and Scale-up: The Case of Walk With Ease.

To maximize limited resources, many health promotion programs are designed to be delivered by volunteer lay leaders. But this model poses challenges to implementation in real-world settings and barriers to successfully scaling-up programs. This study examines the current lay leader training model for Walk With Ease, a Centers for Disease Control and Prevention-funded evidence-based arthritis program delivered at-scale. Recruited volunteers ( = 106) opted into free online or in-person training and agreed to deliver one Walk With Ease program within the following year-only 49%, however, did. Using logistic regression models and qualitative interviews, we explored predictors of volunteer delivery. . Volunteers had higher odds of delivering programs if they trained online (odds ratio [OR] = 9.04, 95% confidence interval [CI: 2.30, 48.36]), previously taught health programs (OR = 15.52, 95% CI [3.51, 103.55]) or trained in the second year of implementation (OR = 27.08, 95% CI [2.63, 415.78]). Qualitative findings underscored that successful volunteers were readied by their previous health education experience. . While online training modes appear effective to prepare experienced volunteers, lay leaders required additional support. This calls into question whether lay-led delivery models are suitable for scaling-up programs with limited resources. Given the many lay-led health interventions for chronic disease self-management, investing in common training and infrastructures for lay leader development could advance the quality and sustainability of real-world program delivery.
