The Role Of Trait Mindfulness, Perceived Stress, And Impulsivity In Understanding The Relationship Between Stress Mindset And Psychological Intimate Partner Aggression, Sarah Joyanna Johnson

Doctoral Dissertations

Perpetration of psychological intimate partner aggression is a pervasive health issue and has been estimated to occur in 60 to 90 percent of relationships. Effects of intimate partner violence on its victims has been demonstrated to have lasting physical and mental health issues. Psychological intimate partner aggression has been demonstrated to have particularly harmful effects, above and beyond those identified in physical intimate partner aggression. Psychological intimate partner aggression has been demonstrated to be impacted by impulsivity, stress-mindset, perceived stress, and mindfulness. The present study proposed to examine a path analysis model of the relation between stress-mindset and psychological intimate …

“Sometimes The People Giving The Care Get A Little Overlooked”: Athletic Trainers’ Personal Use Of Psychosocial Strategies And Interactions With Mental Performance Consultants, Alexander Bianco

Doctoral Dissertations

In National Collegiate Athletic Association Division I (NCAA DI) athletic departments, athletic trainers (ATs) must navigate an array of stressors in the workplace, and are effectively performers themselves (Estock & Simon, 2018, Mazerolle et al., 2013). While ample research has been conducted on the stressors that ATs experience (see Oglesby et al., 2020) there has been limited work surrounding how ATs can best navigate this environment. Therefore, the purpose of the current investigation was to explore NCAA DI ATs’ perceptions of and experiences with the personal use of psychosocial strategies and sport psychology services to manage their stress, improve their …

A Study Of The Effect Of Physiological Stressors On Hypothalamic Regulation Of Reproduction Using An In Vitro System, Lisa L. Amelse

Doctoral Dissertations

Stressors have a negative impact on reproductive efficiency in humans and other animals, which has an economic cost due to infertility treatments for humans and reduced income for food producers. We wished to determine the molecular pathways by which metabolic disturbances and low-level inflammation impact the hypothalamic pituitary gonadal (HPG) axis using an in vitro model. To this end, we used the GT1-7 cell line, an immortalized line expressing the Kiss1R receptor that responds to kisspeptin stimulation with the release of GnRH to assess the impact of stressors on the GnRH-releasing cells. Additionally, we used the KTaV-3 and KTaR-1[A1] …

Psychosocial Effects Of Providing Nursing Care To Patients From A Multi-Casualty, School-Associated Shooting Event, William Travis Mccall

Doctoral Dissertations

Secondary traumatic stress describes symptoms consistent with post-traumatic stress disorder but that result from witnessing or experiencing the trauma of another individual through a helping relationship. The associated symptoms include intrusions, avoidance, and hyperarousal. Secondary traumatic stress is also associated with the development of compassion fatigue and burnout. The current state of the science identifies that secondary traumatic stress may affect those nurses who provide care to critically ill or injured patients. Research has most commonly examined the prevalence of secondary traumatic stress, compassion fatigue, and burnout among nurses in emergency department settings. While attention is frequently given to the …

Child Maltreatment, Perceived Stress, And Opioid Use In Pregnancy, Stephanie Brooke Kors

Doctoral Dissertations

The current study examined pathways from childhood trauma to opioid misuse in pregnancy. We sampled 93 pregnant women at a high-risk pregnancy clinic at a university medical center who were at least in their second trimester. 55 women were considered high-risk due to opioid misuse and 38 women were considered high-risk due to medical reasons other than drug use. Results revealed sexual abuse significantly predicted opioid misuse in pregnancy, while physical abuse, emotional abuse, and neglect did not. Women with histories of childhood sexual abuse reported significantly higher levels of perceived stress during pregnancy than women who did not report …

Roles For The Ventromedial Prefrontal Cortex In Resistance To Acute Social Stress, Johnathon Grizzell

Doctoral Dissertations

The ventromedial aspect of the prefrontal cortex (vmPFC) is an evolutionarily conserved region of the frontal lobe with primary roles in social processing and emotional regulation. During particularly stressful situations, neurons of the vmPFC are recruited and, through dynamic circuit-based activity patterns, help the organism integrate pertinent sensory cues and act in a context-specific manner. In the dissertation that follows, I discuss investigations of vmPFC neural and immune system activity as they confer resilience and susceptibility, respectively, to the effects of acute social defeat stress in male Syrian hamsters. We have previously shown that vmPFC neural activity, as indexed by …

Appraising Opportunities To Better Understand Well-Being And Performance In The Organizational Sciences, Michael Paul Lerman

Doctoral Dissertations

Despite a strong base of literature that shows appraisal (i.e., an individual’s assessment of the relevance of a possibly stressful situation to their own goals and their likelihood of effectively coping with it) is an important predictor of individual emotion, behavior, and performance, appraisal has been largely relegated to theory by the organizational sciences. The purpose of this work is to demonstrate why studying appraisal adds value to organizational science phenomena. This is accomplished through two empirical essays and a theory essay. First, a metaanalysis assesses the extent to which the challenge-hindrance framework, a perspective that explicitly suggests appraisal is …

The Neurochemistry And Neural Circuitry Of Stress Resilience, Brooke Nichole Dulka

Doctoral Dissertations

Stress is a contributing factor in the etiology of several mood and anxiety disorders, and animal models of social defeat have been used to investigate the biological basis of stress-related psychopathologies. Syrian hamsters are highly aggressive and territorial, but after social defeat they exhibit a conditioned defeat (CD) response which is characterized by increased submissive behavior and a failure to defend their home territory against a smaller, non-aggressive intruder. We have previously shown that dominant male hamsters show increased c-Fos expression in the infralimbic (IL) subdivision of the ventromedial prefrontal cortex (vmPFC) following social defeat and display a reduced CD …

A Deep Breathing Intervention For Stress Reduction In 5-Year-Old Children, Tara Jean Veerman

Doctoral Dissertations

This multi-manuscript dissertation concentrates on child stress, an important area of attention for social workers. Many children we work with are exposed to chronic stressors such as poverty, child maltreatment, and other forms of stressors and/or trauma. These experiences can be damaging to a child’s development, especially if they occur early in life, and the effects may be long-lasting. The first manuscript provides an overview of the human stress response and its potential deleterious effects on child brain development. It highlights specific brain regions affected by stress, and possible physical and mental health consequences of stress later in life.Building on …

The Effects Of Racialization On European American Stress In The Nineteenth And Twentieth Centuries, Kimberly T. Wren

Doctoral Dissertations

This dissertation explores disparities in stress among European Americans (EA) and between EA and African Americans (AA) in racialized communities in the nineteenth and twentieth centuries. Comparisons among EA and between EA and AA are conducted to understand the biological consequences of racialization. Racialization is the process of assigning people to hierarchical categories for purposes of political, social, and economic discrimination. This dissertation investigates how racialization might have affected childhood stress using biocultural theory and facets of critical archaeology theory. Indicators of stress from skeletonized individuals in the William M. Bass Donated Skeletal Collection, Hamann-Todd Osteological Collection, and the Robert …

A Grounded Theory Inquiry Into Crying In Women Dealing With The Emotional Stress Of Personal Crisis, Mary Bess Griffith

Doctoral Dissertations

The belief that crying leads to healing is so widely held and of such longstanding that many healthcare professionals—including nurses, physicians, psychiatrists, and psychologists—accept it as fact even though there is little substantiating scientific evidence. Crying is commonly believed to be an essential factor in restoring mind-body equilibrium after physical and/or emotional trauma has been experienced. If, as has been hypothesized by many scientists and healthcare practitioners, emotional crying is a biopsychosocial healing modality, then specifics of its therapeutic praxis, including limitations and ambiguities, should be incorporated into nursing education and practice. In this grounded theory study, the meaning and …

Effects Of Prenatal Stress And Poverty On Fetal Growth, Teresa Anne Lefmann

Doctoral Dissertations

Background. Prenatal stress has negative effects on the developing fetus through the activation of the hypothalamic-pituitary-adrenal (HPA) axis. Programming of the stress response system during gestation has lifelong effects that put the infant at risk for multiple stress-related pathologies. Populations most vulnerable to prenatal stress are African-Americans and individuals of low socioeconomic status.

Methods. The Pregnancy Risk Assessment Monitoring System (PRAMS) research project, a collaboration between the Centers for Disease Control and Prevention and individual state health departments, was utilized for this study. Tennessee data from 2009 were compiled from individual birth certificates and PRAMS questionnaire responses to examine three …

Examining Perceived Life Stress Factors Among Intercollegiate Athletes: A Holistic Perspective, Landon Tyler Huffman

Doctoral Dissertations

The National Collegiate Athletic Association (NCAA) subscribes to the principle of intercollegiate athlete well-being (Article 2.2) which includes health and safety (Article 2.2.3). However, intercollegiate athletes, particularly those competing in arguably the most competitive level of intercollegiate athletics (i.e., NCAA Division I Football Bowl Subdivision [FBS]), are exposed to unique stressors which may compromise their well-being. One dimension which has been received less frequent investigation in the context of athlete welfare is that of spirituality. In lieu of the unique intercollegiate athletic environment and stressors, it is critical to investigate the relationships between the spiritually-related characteristics, specifically religiosity, resiliency, and …

Work/Family Conflict As A Predictor Of Employee Work Engagement Of Extension Professionals, April B. Martin

Doctoral Dissertations

This study utilizes stress theory to explore the effects of work-family conflict and family-work conflict upon the work engagement outcomes of employees. Using a web-based questionnaire with a primary data sample of 2,782 full time Extension professionals in 46 states, this study incorporates the structural equation modeling analytic technique. This study confirmed the single, second order work-family conflict construct consisting of six first order constructs of work-family time, strain and behavior and family-work time, strain, and behavior. The bi-directionality of work-family conflict and family-work conflict was sustained, as numerous research studies have recommended. The structural equation modeling analysis found the …

Overseeing Supervisees Treating Clients Exhibiting Suicidal Behaviors: Its Impact On Clinical Supervisors, Michael Girard Catalana

Doctoral Dissertations

Individuals at risk of suicide often seek mental health treatment (Brook, Klap, Liao, & Wells, 2006; Moscicki, 2001; Souminen, Isometsa, Martunnen, Ostamo, & Lonnqvist, 2004). The clinicians who treat these individuals experience significant levels of stress (Knox, Burkard, Bentzler, Schaack, & Hess, 2006; Ruskin, Sakinofsky, Bagby, Dickens, & Sousa, 2004). Clinical supervisors are an important resource for clinicians (Chemtob, Hamada, Bauer, Kinney, & Torigoe, 1988a; Kleespies, Smith, & Becker, 1990; Knox et al., 2006; Maltsberger, 1992; Ruskin et al., 2004). Researchers recently acknowledged that overseeing clinicians whose client exhibited suicidal behavior is also stressful (Catalana, 2012; Hoffman, 2009; Sanger, 2010). …

The Intersection Between Home And School: Developing A Scale To Measure Parental Perceptions Of Childhood School Stress, Teresa Marie Henke

Doctoral Dissertations

Abstract

Parents in the home and educators in the schools are key adults in the most important contexts in the daily lives of school-age children. In the demanding, achievement, and accountability oriented culture of today, it is expected that children experience normal everyday stressors as they move between these two environments. The impact of stress related to daily hassles has been reported to have both cognitive and physical effects on the present and future well-being of children. This study represented an attempt to advance the understanding of childhood stress in the intersection between school and home by investigating the perceptions …

Mindfulness And Self-Compassion: Exploring Pathways To Adolescent Emotional Well-Being, Karen Leslie Bluth

Doctoral Dissertations

Adolescents today are confronted with the compounded stressors of life in our high-pressured society and the cognitive, physiological, and emotional changes that are characteristic of this stage of development. As a result, they often struggle with self-doubt, leading to depression, anxiety, and maladaptive trajectories. Mindfulness, or paying attention in the moment in an intentional and purposeful way, has been reported to have positive effects on emotional well-being in adults, and shows promise for similar results in recent research with children and adolescents.

Moreover, the mechanisms through which being mindful achieves positive outcomes has only recently been explored, and has not …

“Everything Was Different”: An Existential Phenomenological Investigation Of Us Professional Basketball Players’ Experiences Overseas, Rainer Josef Meisterjahn

Doctoral Dissertations

Globalization in the sports world is a phenomenon that has received considerable attention in the sport studies literature (Maguire, 1994, 2004). A significant aspect of globalization is labor migration in professional sports, which has been investigated extensively in recent years (e.g., Magee & Sugden, 2002; Takahashi & Horne, 2006). Basketball is one sport that has been discussed in this context (Falcous & Maguire, 2005). The sports encounters of athletes in foreign cultures are often diverse and entail differing pressures, rewards, and interdependencies (Falcous & Maguire, 2005). Players may deal with significant stressors such as performance expectations as is typical of …
