Item Perceived discrimination, political efficacy, and political participation in American Indian adults(Frontiers Media SA, 2024-03) Wood, Zachary J.; John-Henderson, Neha A.Introduction: Psychological factors linked to political participation are largely understudied in American Indians. Prior work notes relatively low levels of participation compared to other racial and ethnic groups and suggests that identification with being American Indian is linked to overall levels of civic engagement in part through perceptions of group discrimination. Methods: In the current work, in a sample of 727 American Indian adults, we created two groups: Group 1 (N = 398) reported perceived discrimination related to race, and Group 2 (N = 329) reported perceived discrimination not related to race or ethnicity. We investigated the relationships between individual experiences of everyday discrimination related to race, levels of political efficacy, and political participation (Group 1), and individual experiences of everyday discrimination not related to race or ethnicity, political efficacy, and political participation (Group 2). Results: We found that greater experiences of everyday discrimination related to race was associated with higher levels of political participation through increased levels of internal and collective efficacy. In contrast, greater experiences of everyday discrimination related to race was associated with higher levels of political participation through lower external political efficacy. For Group 2, we found that greater experiences of everyday discrimination not related to race or ethnicity was not directly associated with political participation, but mediation analyses revealed a relationship with lower levels of political participation through decreased internal and collective efficacy. The indirect effect through external political efficacy was not significant. Discussion: Given low levels of American Indian political participation, political efficacy could be a target for interventions aiming to increase participation in the political system.Item Profiles of historical loss and childhood trauma as predictors of mental and cardiometabolic health in American Indian adults(Elsevier BV, 2023-12) John-Henderson, Neha A.; Ginty, Annie T.Cardiometabolic disease and mental health conditions are two major contributors to persistent inequities in health and life expectancy for American Indian adults. The atrocities associated with European colonization are linked to intergenerational psychological and emotional wounding (i.e., historical trauma) and high incidence of childhood trauma. Prior work has examined the independent relationships of childhood trauma and thoughts about historical loss with cardiometabolic and mental health in American Indians. In the current work, we used a data-driven approach to identify profiles of childhood trauma and frequency of thoughts about historical loss, and then examined how these profiles related to cardiometabolic and mental health in a sample of American Indian adults from across the United States (N = 727). We found that a profile characterized by high levels of childhood trauma and high frequency of thoughts about historical losses was associated with the greatest risk for mental health conditions. The profile characterized by the highest levels of childhood trauma and by moderate frequency of thoughts about historical losses was associated with the largest risk of cardiometabolic conditions. The findings represent an important first step towards understanding how childhood trauma and thoughts about historical loss may simultaneously inform enduring inequities in American Indian health.Item Childhood Trauma and Cortisol Reactivity: An Investigation of the Role of Task Appraisals(Frontiers Media SA, 2022-04) Counts, Cory J.; Ginty, Annie T.; Larsen, Jade M.; Kampf, Taylor D.; John-Henderson, Neha A.Background: Childhood adversity is linked to adverse health in adulthood. One posited mechanistic pathway is through physiological responses to acute stress. Childhood adversity has been previously related to both exaggerated and blunted physiological responses to acute stress, however, less is known about the psychological mechanisms which may contribute to patterns of physiological reactivity linked to childhood adversity. Objective: In the current work, we investigated the role of challenge and threat stress appraisals in explaining relationships between childhood adversity and cortisol reactivity in response to an acute stressor. Methods: Undergraduate students (n = 81; 61% female) completed an online survey that included general demographic information and the Risky Families Questionnaire 24 h before a scheduled lab visit. In the lab, a research assistant collected a baseline salivary cortisol sample. Following the baseline period, participants were read instructions for the Trier Social Stress Test (TSST), a validated psychological lab stressor. Next, they completed a challenge vs. threat task appraisal questionnaire and completed the speech and math portion of the TSST. Twenty minutes following the start of the TSST, a second salivary sample was collected to measure changes in salivary cortisol following the TSST. Results: Linear regression analyses adjusted for age, sex, childhood socioeconomic status (SES), and baseline cortisol levels, showed childhood adversity associated with changes in cortisol levels [B = –0.29 t(73) = –2.35, p = 0.02, R2=0.07]. Linear regression analyses controlling for age, sex, and childhood SES showed childhood adversity associated with both challenge [B = –0.52 t(74) = –5.04, p < 0.001, R2=0.24] and threat [B = 0.55 t(74) = 5.40, p < 0.001, R2=0.27] appraisals. Significant indirect effects of childhood trauma on cortisol reactivity were observed through challenge appraisals [B = –0.01 (95% confidence interval = –0.02, –0.003)], and threat appraisals [B = –0.01 (95% confidence interval = –0.01, –0.003)]. Conclusion: Childhood adversity may contribute to blunted cortisol reactivity, a pattern of response which is linked to obesity, addiction, and other behavior-related diseases. Our findings suggest that this relationship is in part a product of stress appraisals.Item COVID-19 and food insecurity in the Blackfeet Tribal Community(Springer Science and Business Media LLC, 2022-05) John-Henderson, Neha A.; Oosterhoff, Benjamin J.; Johnson, Lester R.; Lafromboise, Mary Ellen; Malatare, Melveena; Salois, EmilyTo examine the impact of the COVID-19 pandemic on food insecurity in the Blackfeet American Indian Tribal Community. American Indian adults residing on the Blackfeet reservation in Northwest Montana (n = 167) participated in a longitudinal survey across 4 months during the COVID-19 pandemic (August 24, 2020- November 30, 2020). Participants reported on demographics and food insecurity. We examined trajectories of food insecurity alongside COVID-19 incidence. While food insecurity was high in the Blackfeet community preceding the pandemic, 79% of our sample reported significantly greater food insecurity at the end of the study. Blackfeet women were more likely to report higher levels of food insecurity and having more people in the household predicted higher food insecurity. Longitudinal data indicate that the COVID-19 pandemic exacerbated already high levels of food insecurity in the Blackfeet community. Existing programs and policies are inadequate to address this public health concern in AI tribal communities.
