Abstract Background We conducted Listening Sessions using a modified version of boot camp translation (BCT), a validated community engaged approach, to engage American Indian community members in the Great Plains and the Pacific Northwest to develop culturally and locally relevant colorectal cancer (CRC) screening messages and materials. Methods CRC is one of the leading causes of cancer death in the US and disproportionally affects American Indian adults. Routine CRC screening leads to earlier diagnosis and prolonged survival from the disease. In partnership with Great Plains Tribal Leaders Health Board (GPTLHB), South Puget Intertribal Planning Agency (SPIPA), and National Association of Chronic Disease Directors, we used a modified BCT approach to obtain feedback from tribal communities to create CRC screening messages and materials. To make the BCT process more meaningful for our partner communities, we reframed the BCT sessions by referring to them as Listening Sessions. The Listening Session engagement process was designed to help community leaders and champions learn about local barriers and gaps in care (listen), share health information in a collaborative way (empower), and develop messages and materials that resonate with and motivate community members to take control of their health (co-create). Eligible tribal community members from GPTLHB and SPIPA were between the ages of 45-75 and able to participate in three Listening Session meetings (one five-hour in-person meeting including expert presentations, brainstorming opportunities, and interactive small group sessions, and two follow-up virtual sessions (one-hour each) to refine messages and materials). Results Common Themes. Both groups emphasized the importance of using a multigenerational approach by including grandchildren and Elders in the messages and materials. Additionally, they highlighted the need for materials to be relatable and culturally relevant by incorporating local cultural imagery and traditions and multigenerational family support .Differing Themes. The GPTLHB findings focused specifically on including Lakota words to reinforce cultural identity, using visuals for colon health education, and incorporating details about healing traditions. The SPIPA findings recommended highlighting intertribal milestones like the canoe journey and incorporating water as a symbol of spiritual healing. Materials and Dissemination Methods. Preferred materials and channels for dissemination were: 1) fact sheets, posters, and visual stories to be distributed in-clinic or at community events, 2) animated videos for CRC screening education to be shown in clinic, 3) live action videos with community member CRC stories to be shown in clinic.
