The objective of this trial is to evaluate the efficacy of a culturally tailored intervention Faith in Action! on breast cancer screening adherence rates among Korean American women. A parallel cluster randomized trial with staggered roll-out was designed to evaluate the efficacy of the Faith in Action! intervention, a church-based small group education and lay health navigator program, delivered by trained church members, on breast cancer screening among Korean American women. Eligible participants include women, ages 45–75 years, who attend a participating church in Los Angeles County, do not have a breast cancer diagnosis, and did not receive a mammogram in the last 2 years. The primary outcome is adherence to breast cancer screening guidelines within 6 months from the end of the intervention. Secondary outcomes include adherence to breast cancer screening within 1 year and knowledge on breast cancer screening. 

Findings: This study addresses a current need for developing and testing culturally tailored interventions to increase breast cancer screening adherence among Korean American women. Leveraging faith-based organizations and delivering the intervention through trained lay health navigators, if found to be effective, has the potential to provide a scalable and sustainable strategy for increasing screening rates and ultimately improve health and well-being as well as reduce cancer-related disparities in this population.
