A Systematic Review of Trauma Interventions in Native Communities.

American Indian/Alaska Native and First Nations communities suffer from health disparities associated with multiple forms of trauma exposure. Culturally appropriate interventions are needed to heal current and historical trauma wounds. Although there are evidence-based trauma interventions for other populations, few have been implemented or evaluated with Native communities. Understanding the extant research on trauma interventions in Native communities is crucial for advancing science and filling gaps in the evidence base, and for meeting the needs of underserved people. In this systematic review of the literature on trauma interventions in Native communities in the United States, Canada, Australia, and New Zealand, we identified 15 studies representing 10 interventions for historical and/or current trauma. These studies involved the community to some extent in developing or culturally adapting the interventions and suggested positive outcomes with regard to historical and interpersonal trauma symptoms. However, notable limitations in study design and research methods limit both internal validity and external validity of these conclusions. Only one study attempted (but did not achieve) a quasi-experimental design, and small sample sizes were persistent limitations across studies. Recommendations for researchers include working in partnership with Native communities to overcome barriers to trauma intervention research and to increase the rigor of the studies so that ongoing efforts to treat trauma can yield publishable data and communities can secure funding for intervention research.
