However, limited prospective research prevents any directional conclusions. No known studies have assessed emotion regulation with PTSS in American Indians, a high-risk population for poor mental health outcomes. The present prospective study explored whether emotion regulation strategies (cognitive reappraisal, expressive suppression) predicted later PTSS related to the COVID-19 global pandemic in a solely American Indian sample. American Indian participants (N = 210; Mean (SD) age = 54.85(13.08) years, 58.7% female) completed the Emotion Regulation Questionnaire (ERQ) during Phase 1 (a few weeks before pandemic declaration) and the Impact of Event Scale-Revised (IES-R) with respect to the COVID-19 pandemic during Phase 2 (7-8weeks after pandemic declaration). Bivariate correlations and hierarchical linear regression analyses were utilized. ERQ reappraisal was negatively associated with IES-R total scores, such that higher reappraisal predicted lower PTSS. In contrast, ERQ suppression was positively associated with IES-R total scores, such that higher suppression predicted higher PTSS. Greater suppression and lower reappraisal predicts PTSS in response to the COVID-19 pandemic in an entirely American Indian sample, providing critical information for future interventions in a population at high-risk for mental health disparities.
