Iw.apiya American Indian pilot clinical trial: Historical trauma and group interpersonal psychotherapy.

American Indians face pervasive trauma exposure, collective histories of communal suffering, and elevated risk for depression and posttraumatic stress disorder. In addition to socioeconomic barriers, access to culturally responsive treatment is limited, which may compromise treatment engagement. The Iw.apiya study piloted the Historical Trauma and Unresolved Grief Intervention (HTUG), combined with Group Interpersonal Psychotherapy (IPT), to reduce symptoms of depression and related trauma and grief. The study hypothesized that HTUG + IPT would lead to greater group engagement and decreased depression and related symptoms compared with IPT-Only. American Indian adults (n = 52) were randomized into one of two 12-session interventions, HTUG + IPT or IPT-Only, at two tribal sites: one Northern Plains reservation (n = 26) and one Southwest urban clinic (n = 26). Standardized measures assessed depression, posttraumatic stress disorder, grief, trauma, and substance use. Data were collected at screening, baseline, end of intervention, and 8 weeks postintervention; depression and group engagement measures were also collected at Weeks 4 and 8 of the intervention. Depression scores significantly decreased for both treatments, but there were no significant differences in depression between the two groups: IPT-Only (30.2 ± 6.4 at baseline to 16.7 ± 12.1 at follow-up) and HTUG + IPT (30.2 ± 8.1 at baseline to 19.9 ± 8.8 at follow-up). However, HTUG + IPT participants demonstrated sign...
