Process Evaluation of a Faith-Based Multicomponent Behavioral Intervention to Reduce Stroke Risk in Mexican Americans in a Catholic Church Setting: The SHARE (Stroke Health and Risk Education) Project

Church-based stroke prevention programs for Hispanics are underutilized. The Stroke Health and Risk Education (SHARE) project, a multicomponent cluster-randomized trial, addressed key stroke risk factors among predominantly Mexican Americans in a Catholic Church setting. Process evaluation components (implementation, mechanisms of impact, and context) are described. Partner support promoted positive health behavior change. Motivational interviewing calls were perceived as helpful, however, barriers with telephone delivery were encountered. Intervention exposure was associated with theory constructs for targeted behaviors. We conclude that health behavior interventions to prevent stroke can be successfully implemented for Mexican Americans within a Catholic Church setting, with parish priest support.
