"Improving Chronic Illness Self-Management with the Apsáalooke Nation: The Báa nnilah Project, a cluster randomized trial protocol." Contemporary Clinical Trials 119 (2022): 106835.1551-7144https://scholarworks.montana.edu/handle/1/17526Chronic illness (CI) is a major cause of morbidity and mortality for Indigenous people. In Montana, Indigenous communities disproportionately experience CI, a legacy of settler colonialism. For over two decades, Messengers for Health, an Apsáalooke (Crow Indian) non-profit, and Montana State University have partnered to improve community health using a community-based participatory research (CBPR) approach. We developed Báa nnilah, an intervention utilizing community strengths, to improve CI self-management. This manuscript describes the protocol for a cluster randomized trial with two arms: an intervention group and a wait list control group, who both participated in the Báa nnilah program. Enrollment occurred through family/clan networks and community outreach and attended to limitations of existing CI self-management interventions by using an approach and content that were culturally consonant. Participants received program materials, attended seven gatherings focused on improving CI management, and received and shared health information through storytelling based on a conceptual framework from the Apsáalooke culture and incorporating CI self-management strategies. Participant support occurred within partnership dyads during and between gatherings, from community mentors, and by program staff. The study used mixed methods to evaluate the intervention, with qualitative measures including the Short Form Health Survey (SF-12), Patient Health Questionnaire (PHQ-9), Patient Activation Measure (PAM), and a suite of PROMIS measures, various physical tests and qualitative survey responses, semi-structured interviews, and outcomes shared by participants with program staff. We hypothesized that Báa nnilah would significantly improve participant health outcome measures across multiple dimensions with quality of life (QoL) as the primary outcome.en-UScc-by-nc-ndhttps://creativecommons.org/licenses/by-nc-nd/4.0/CBPRCluster randomized trialIndigenousChronic illnessSelf-managementCommunity resilienceArticle
