This community-based participatory research (CBPR) project developed Insuring Good Health- a website and video series designed to improve engagement with health insurance and Affordable Care Act reforms. We conducted a lagged-control cluster randomized controlled trial to evaluate Insuring Good Health with racially and ethnically diverse adults seeking services in medically underserved areas within the Detroit, Michigan metropolitan area. Outcomes were assessed at baseline and at 6 and 9 months postintervention, and including self-efficacy, knowledge, beliefs, and intention to seek help with insurance navigation and care. Insuring Good Health was associated with increased intention to seek help with insurance navigation and care, and improved beliefs around preventive care.
