Developing Culturally Tailored Mobile Web App Education to Promote Breast Cancer Screening: Knowledge, Barriers, and Needs Among American Indian Women.

American Indian (AI) women face disproportionate rates of breast cancer mortality and cancer disparities. This study conducted qualitative research to assess perspectives of AI women towards breast cancer screening, knowledge, barriers, and needs about mobile web app-based education to promote breast cancer screening. This study, in collaboration with the Yankton Sioux Tribe (YST), followed a community-based participatory research approach and conducted two focus groups with a total of 22 YST women aged 40-70 years living on reservation in rural South Dakota. Each group consisted of 11 local professionals working in healthcare and social services and community members. A grounded theory was used for the qualitative analysis. A large portion of participants reported having prior knowledge about breast cancer and screening methods, yet lacked awareness of the detailed procedure and recommended guidelines. Competing priorities and cost of mammograms were noted as major barriers to screening. Participants wanted to learn-in a convenient and easy-to-understand manner-more about breast cancer and prevention from a credible source. Both groups were favorable toward novel educational tools, such as the mobile web app education, and cited potential health benefits, particularly for women aged 40s to 60s. Our findings highlighted the importance of creating effective, culturally tailored educational interventions built into programs specific to AIs to increase understanding about breast cancer screening and promote screening behaviors among AI women. Particular attention to how AIs' culture, beliefs, and barriers are implicated in screening behaviors could help with developing culturally tailored health education tools for this population.
