Three Studies Examining The Mechanisms Linking Stress Exposure To Delinquency And Substance Use Among North American Indigenous Adolescents, Dane Steven Hautala

Department of Sociology: Dissertations, Theses, and Student Research

Objective: The purpose of this dissertation research was to examine in three separate studies the mechanisms linking a variety of stressors to delinquency/substance use among North American Indigenous (i.e., American Indian and Canadian First Nations) youth.

Method: Data for the three empirical chapters come from an eight-wave longitudinal study of 676 Indigenous youth and their caretakers from three U.S. reservations and four Canadian First Nations reserves.

Study 1 Results: The objective was to examine the intergenerational transmission of problem behavior from female caretakers to their children via caretaker stress exposure, psychosocial functioning, and parenting practices. Early caretaker …

Into The Gap: A Mixed Methods Study Of Acculturation, Stress, And Refugee Family Functioning, Kieu Anh T. Do

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Every day, new waves of refugees result from increasing social, political and environmental instabilities around the world. Numerous studies have detailed the various stressors and adjustment issues that refugees face when resettled in a new host society. The majority of these studies focus on individual-level variables and not on the family as a whole. Thus, more studies are needed to understand how refugee families adjust in the resettlement context in order to promote positive outcomes. Studies that have examined family-level functioning often focus on how acculturative differences increase stress in refugee families, contributing to higher levels of familial tension and …

The Contribution Of A Polygenic Risk Score To Individual Differences In Aggressive Behavior: The Moderating And Mediating Roles Of Stressful Events, Christa C. Christ

Department of Psychology: Dissertations, Theses, and Student Research

Although aggression can be beneficial in certain situations (e.g. playing sports, self-defense), excessive and inappropriate aggression can lead to adverse physical and psychological health outcomes in both perpetrators and victims. Genetic susceptibility to negative environments can increase the likelihood of aggressive behavior in the context of situational risk factors. Low efficiency of serotonin neurotransmission and exposure to stress appear to play a prominent role in the etiology of aggressive behavior. A set of three studies assessed the contribution of polygenic risk (TPH2 rs4570625, SLC6A4 5-HTTLPR+rs25531, HTR1B rs13212041, MAOA uVNTR) to aggressive behavior, including alcohol-related aggression, in university students at varying …

Nature As A Buffer: The Physiological Effects Of Exposure To Nature On Stress, Tyler J. Stading, Jeffrey R. Stevens

UCARE Research Products

Exposure to images of nature following a stressful event can reduce physiological measures associated with stress. The objectives of this study was to determine whether exposure to nature before the stressor can buffer the stress response. We varied whether nature or urban images were viewed before or after a stressor and measured galvanic skin response in our participants. We describe how order of presenting the stressor influences nature’s calming effect on physiology.
