Evidence-based interventions hold promise for reducing gaps in health equity across diverse populations, but evidence about effectiveness within these populations lags behind the mainstream, often leaving opportunities to fulfill this promise unrealized. Mismatch between standard intervention outcomes research methods and the cultural and community contexts of populations at greatest risk presents additional challenges in designing and implementing rigorous studies; these challenges too often impede efforts to generate needed evidence. We draw on experiences with American Indian and Alaska Native communities to illustrate how consideration of culture and context can constructively shape intervention research and improve the quality of evidence produced. Case examples from a partnership with one American Indian community highlight opportunities for increasing alignment in intervention development, research design, and study implementation to maximize both validity and feasibility. We suggest that responsively tailoring intervention outcomes research to cultural and community contexts is fundamental to supporting health equity.

Indigenous communities often face disproportionate challenges across a variety of health domains, and effective prevention strategies are sorely needed. Unfortunately, evidence is scant regarding what approaches are effective for these communities. A common approach is to take an evidence-based practice or program with documented effectiveness in other populations and implement it with Indigenous populations. While a science of intervention adaptation is emerging, there remains little guidance on processes for adaptation that strategically leverage both existing scientific evidence and Indigenous prevention strategies. In this paper, two case studies illustrate promising practices for adaptation, documenting the approaches of two research teams funded under the National Institutes of Health's initiative to support Intervention Research to Improve Native American Health (IRINAH). These teams worked with distinct Indigenous populations in the USA and Canada to culturally adapt the same prevention program, the Iowa Strengthening Families Program for Parents and Youth 10-14. The approaches of these two teams and the programs that resulted are compared and contrasted, and critical elements of adaptation in partnership with Indigenous communities are discussed.

Background: Early substance use threatens many American Indian/Alaska Native (AI/AN) communities, as it is a risk factor for maladaptive use and adverse health outcomes. Marijuana is among the first substances used by AI/AN youth, and its use becomes widespread during adolescence. Interventions that delay or reduce marijuana use hold the promise of curbing substance disorders and other health risk disparities in AI/AN populations.Objectives: We evaluated the effectiveness of the Circle of Life (COL) program in reducing marijuana use among young AI adolescents. COL is a culturally tailored, theory-based human immunodeficiency virus (HIV) and sexually transmitted disease (STD) intervention shown to delay sexual initiation among AI youths.Methods: We conducted secondary analyses of data from a school-based group randomized trial conducted between 2006 and 2007 in all 13 middle schools on a rural, Northern Plains reservation (N = 635, 47% female). We used discrete-time survival analysis (DTSA) to assess COL effectiveness on risk of marijuana initiation among AI youths and latent growth curve modeling (LGCM) to evaluate effects on frequency of marijuana use over time.Results: DTSA models showed that the overall risk of marijuana initiation was 17.3% lower in the COL group compared to the control group. No intervention effect on frequency of marijuana use emerged in LGCM analyses.Conclusion: COL is a multifaceted, culturally tailored, skills-based program effective in preventing marijuana uptake among AI youth.

Background: There is a need to understand resiliency factors which can be used to inform and design interventions to prevent externalizing problems, substance use, and depressive symptoms among American Indian (AI) youth. Objectives: The present study examined the role of self-efficacy in externalizing problems, alcohol use, and depressive symptoms among AI youth from the North American plains. Methods: Participants for this study included 146 (53 boys and 93 girls) adolescents, with an age range of 13-18 (M = 14.5) years of age. Results: High self-efficacy for resisting negative peer influences predicted both lower rates of alcohol use and fewer externalizing behaviors. Furthermore, higher levels of both academic and social self-efficacy predicted fewer depressive symptoms. The hypothesis that academic self-efficacy would predict depressive symptoms was not supported. Conclusion: As expected, the best-fitting path model showed self-efficacy for resisting negative peer influences predicting both alcohol use and externalizing problems, and social self-efficacy (as well as being female) predicting depressive symptoms among AI youth. Therefore, this study supports the importance of self-efficacy beliefs for alcohol use and externalizing problems, as well as depressive symptoms, among AI youth. [ABSTRACT FROM AUTHOR]
