Effects Of Development On Hpa Function Following Pubertal Stress, Brittany D. Elliott

Graduate Theses, Dissertations, and Problem Reports

For women, two of the greatest risk factors for affective disorders are adversity experienced during puberty and later becoming pregnant. We have created a translationally relevant mouse model where we address these complex risk factors. Previously, we discovered that pregnant mice (dams) that experienced chronic variable stress (CVS) during puberty display a blunted hypothalamic-pituitary-adrenal (HPA) response when exposed to an acute stressor. Interestingly, this alteration only first becomes apparent during pregnancy, which is a sensitive period for these effects due to normative neuroendocrine changes. Further investigation of the mechanisms underlying this dysfunction revealed altered gene expression in the paraventricular nucleus …

Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber

Cal Poly Humboldt theses and projects

This study aimed to investigate the potential impact of negative social media content on athletes' cortisol levels and subsequent performance. The study focused on the change in cortisol levels and differences in free throw performance, based on previous research findings. We hypothesized that negative social media postings would increase the stress experienced by student-athletes, resulting in elevated cortisol levels and decreased performance. Additionally, participants (n = 8) completed a questionnaire to examine the interaction between preexisting fear and the biological stress response. Contrary to expectations, there was no significant change in stress response, and negative postings did not have …

Investigation Into The Comorbidities Of Disordered Eating And Social Anxiety Disorder In College Students, Alice Mccraney

Honors Theses

In recent years, psychiatrists have reported a trend that individuals with social anxiety disorders are more likely to also have disordered eating and vice versa. Research into this connection has suggested that risk factors, such as stress reactivity, negative self- esteem, perfectionism and fear of negative evaluation are potential links. This is important because understanding the correlation between the two disorders could help develop better treatments plans for people who suffer from these disorders. This study investigates the relationship between the two. A total of 257 college students between ages 18-22 completed a questionnaire using the Disordered Eating Attitude Scale …

Examining Difference In Social Perceptions Between Women Using Hormonal Contraceptives And Naturally Cycling Women, Caroline B. Johnson

Biological Sciences Undergraduate Honors Theses

The term “stress” refers to a person’s psychological and physiological response to the demands and pressures of the world around them (Farlex, 2021). Past research has shown that stress can have negative side effects on a person’s well-being (Aneshensel et al., 1991; Wunsch et al., 2017; Michie, 2002). Although people experience stress, some people perceive more stress than others. Perceptions are important because the way one understands certain conditions can elicit distinct emotional and physiological responses (Kemeny, 2003). An important factor that has not received a lot of attention is women’s use of hormonal contraceptives. In the United States, 24.4% …

Analysis Of Test Anxiety In Human Anatomy And Physiology I Students At The University Of Mississippi, Anne Piazza

Honors Theses

Student anxiety, specifically test anxiety, is common hindrance to student performance in various courses including Human Anatomy and Physiology at the University of Mississippi. Through a sequence of three surveys we collected demographic information, anxiety data related to the course, and test anxiety in general We researched factors that could potentially influence student anxiety such as at what point in the semester the student is evaluated, when students feel the most stressed, outcomes on previous evaluations, and perceived outcomes of the course. We also examined what effect the anxiety has on the student such as lowered performance, lowered test scores, …

A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab

Dissertations, Theses, and Capstone Projects

Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …

Behavioral, Endocrine, And Neural Responses To Stress In Postpartum And Nulliparous Rats : Potential Mechanisms Of Postpartum Stress Resilience, Joanna Medina

Legacy Theses & Dissertations (2009 - 2024)

Major depressive disorder is one of the most pervasive psychiatric illnesses in the United States. Women are at greater risk for developing depression, particularly during their childbearing years. Approximately 17% of new mothers develop postpartum depression within 4 weeks after parturition. The risk for postpartum depression is even greater in women who do not breastfeed or stop breastfeeding early. Major depressive disorder and postpartum depression share the same symptomology and common etiological bases. Dysregulated stress responses, dopamine activity, and neuroinflammation are recognized mechanisms for depression. The transition to motherhood encompasses physiological and behavioral adaptations in the brain essential for ensuring …

Fall Reading Week: Exploring The Effects On Student Well-Being, Roobina Medhizadah

Theses and Dissertations (Comprehensive)

Mental health is a concerning issue in post-secondary institutions across Ontario. Post-secondary students are challenged with many stressors such as time management and living independently for the first time (Wagner & Rhee, 2013). In an attempt to help students, maintain or improve their mental health, universities across Ontario have implemented fall reading week, a mid-semester break (Poole et al., 2017). Previous studies (Cramer & Pschibul, 2017; Poole et al., 2017) provided mixed results in whether fall reading week positively influences student mental health and well-being. To date, few studies have explored the influence of fall reading week on student health …

Undergraduates And Stress, Mahra Crone

Honors Projects

America is facing a serious mental health crisis, which may be an effect of increased chronic stress. Students, in particular, are vulnerable to this hazard as most face a moderate to extreme amount of stress. The programs which colleges and universities have put into place are outdated. Ineffective treatment of mental health crises leads to disastrous consequences. The present study analyzed the effects of major and grade level on stress level and sources of stress for undergraduate universities at both a large, public university and a small, private college. The author found that a student’s grade level and choice of …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

Characterization Of A Novel, Stress-Responsive Sexually Dimorphic Corticotropin-Releasing Factor Receptor 1 (Crfr1) Nucleus In The Rostral Anteroventral Periventricular Nucleus Of The Mouse, Zachary Julius Rosinger

Legacy Theses & Dissertations (2009 - 2024)

Within the United States, women are at double the risk of men to develop a stress-related mood disorder (e.g., anxiety or depression) during their reproductive years (Kornstein et al., 2000; Kessler et al., 2005). Many factors contribute to the potential sex difference in such disorders, including gonadal hormones (hypothalamic-pituitary-gonadal axis; HPG) and how they interact with the stress response system, or hypothalamic-pituitary-adrenal (HPA) axis. Corticotropin-releasing factor (CRF) signals through binding the GS-coupled receptor, CRF receptor 1 (CRFR1), and activity between CRF/CRFR1 regulates the hormonal and behavioral stress response (Chen et al., 1993; Bale and Vale, 2004; Heinrichs et al., 1995; …

Service Dogs For Veterans With Ptsd: Taxonomy, Work Stress Reduction, And Matching, Lindsay Parenti

Graduate Theses, Dissertations, and Problem Reports

Research suggests that many veterans with post-traumatic stress disorder (PTSD) struggle with reintegration (Sayer et al., 2010), but are unlikely to seek help or complete treatment (Schottenbauer et al., 2008). To make matters worse, available treatment options are often time consuming, challenging, and/or associated with negative side effects (Carafano & Hutchinson, 2017). Using animals as a treatment modality for veterans with PTSD is an emerging topic of interest and has shown promise (Owen, et al., 2016; Richie et al., 2016). However, several factors have hindered the advancement of this field. Obstacles include a lack of standard terminology and classification system, …

Evaluation Of Neurobiological Risk Factors For Alcohol Consumption; Convergent Evidence For Predispositional Effects Of Brain Volume, David Baranger

Arts & Sciences Electronic Theses and Dissertations

Alcohol is one of the most widely used psychoactive substances and accounts for 5% of global disease burden. The goal of the present work is to help advance efforts to both identify prognostic markers of risk, and to understand the mechanisms by which alcohol consumption impacts health. Early life stress is one of the strongest predictors of mental illness, including alcohol dependence, and has been hypothesized to impact risk via modulation of striatal reward functions and reward learning. Studies examined the effect of stress on reward learning and processing, and tested for moderation by genetic and environmental risk. Results were …

Hpa Axis Genetic Variation And Life Stress Influences On Functional Connectivity In Resting State Networks, Tara Ann Miskovich

Theses and Dissertations

Stressful or traumatic experiences are a key risk factor for developing psychopathology, primarily through the impact that chronic stress has on hypothalamic-pituitary-adrenal (HPA) axis functioning. The HPA axis regulates the stress response but can become dysregulated with chronic activation and impact brain functioning. In addition to environmental stressors, genetic variation in genes in the HPA axis appear to influence HPA axis functioning and is also related to disruption in brain functioning, particularly in the context of high life stress. The current study focused on examining potential mechanisms through which trauma and stress interacts with HPA axis genes to impact key …

Effects Of An Early Life Immune Challenge On Body Growth, Personality, Mating Behaviors, And Brain Development Of Zebra Finches (Taeniopygia Guttata), Ahmet Kerim Uysal

USF Tampa Graduate Theses and Dissertations

The developmental stress hypothesis predicts that an aversive condition, such as decreased food intake, predation, and social isolation, in the early developmental stage could have long term effects on behaviors and brain development of an animal. In nature, bird nestlings are susceptible to various factors, such as malnutrition, infections, and parasites. Effects of early life stress on adulthood have been extensively studied with some stressors including malnutrition. However, immune challenges as an early life stressor and their long-term programming effects on adult behaviors are yet to be studied in detail. The goal of the current study was to investigate changes …

The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Theories considering the etiology of psychopathy suggest that trauma exposure, specifically childhood maltreatment and sexual abuse, is related to the development of callous-unemotional traits in children and adolescents, which are precursors to psychopathic traits in adulthood. Furthermore, posttraumatic stress disorder has an opposite relationship with many of the emotional and behavioral components of the two-factor model of psychopathy. Specifically, PTSD is positively associated to IA and traits associated with it and negatively associated with FD. Thus, this study sought to expand upon the current theories of a trauma-based etiology of psychopathy by investigating the relationship between trauma, PTSD, and psychopathic …

Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards

Electronic Theses and Dissertations

There is an urgent need to find effective interventions to prevent and reduce obesity as it is associated with chronic disease and decreased quality of life. Gaining a better understanding of how modifiable variables such as stress, sleep, physical activity, and food insecurity are related to eating behaviors associated with obesity is essential to guide the direction of future interventions and research. Interventions that hold promise need to be tested to determine if they have merit or not. This dissertation presents three papers. Two papers are cross-sectional studies evaluating associations between eating behaviors, obesity, and modifiable variables (stress, sleep, physical …

Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders

University of New Orleans Theses and Dissertations

Stress and anxiety negatively impact the working memory system by competing for executive resources. Broad memory deficits have been reported in individuals with chromosome 22q11.2 deletion syndrome (22q11.2DS). We investigated anxiety and physiological stress reactivity in relation to visuospatial working memory impairments in 20 children with 22q11.2DS and 32 typically developing children (M = 11.10 years, SD = 2.95). Results indicate reduced post-stress RSA recovery and overall increased levels of cortisol in children with 22q11.2DS. Additionally, anxiety mediated the relationship between 22q11.2DS and visuospatial working memory impairment. However, there was no indication that stress response physiology mediated this association. …

This study explored using no-reward markers (NRMs). Dogs were taught a novel trick. In the IG group dogs’ errors were ignored; in the NRM group they elicited a tone. Performance and stress were evaluated. IG dogs reached higher levels of performance, with no difference in the frequency of stress behaviors.

The Influence Of Prenatal Stress On Behaviors Associated With Schizophrenia And Autism Spectrum Disorder., Harold Bauerle

Graduate College Dissertations and Theses

Disorders such as schizophrenia (SCZ) and austism spectrum disorder (ASD) have long been associated with prenatal stress. In these three experiments, we attempted to correlate stress during gestation with behaviors considered to have good facial validity with SCZ and ASD in both juvenile and adult animals. To differentiate the effects of prenatal stress (PS) from the effects of early life stress due to a dam's behavior (MS), half of offspring animals were cross fostered to dams treated in the alternative condition as the offspring during pregnancy in experiments 2 and 3. In experiment 1, but not in 2 or 3, …

Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens

Walden Dissertations and Doctoral Studies

There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …

Alcohol Use Disorders And An Fmri Stress Task: A Connectivity Analysis, Natasha E. Wright

Theses and Dissertations

Little research has been conducted on neuronal stress processing in individuals

with alcohol dependence (AD). The present study examined neural stress response in AD individuals compared to controls using an fMRI stress task, assessing amygdala

activation and its connectivity to the medial prefrontal cortex (mPFC). Further, the study

analyzed the impact of hormone levels and subjective stress on frontal-limbic

connectivity patterns.

Ten abstinent AD individuals and 11 controls were recruited. Subjects

participated in an fMRI stress task. A region of interest (amygdala) analysis was

conducted using area-under-the-curve. This activation was then examined in a whole brain functional connectivity analysis. Follow-up …

Associations Between Hypothalamic-Pituitary-Adrenal Axis System Gene Variants And Cortisol Reactivity In Preschoolers: Main Effects And Gene-Environment Interactions, Haroon I. Sheikh

Electronic Thesis and Dissertation Repository

Exposure to stressful events during early development has consistently been shown to produce long lasting effects on the hypothalamic-pituitary-adrenal (HPA) axis, which may increase vulnerability to mood and anxiety disorders. Recently reported genetic association studies indicate that these disorders may be influenced, in part, by gene-environment interactions (GxE) involving polymorphisms within the corticotrophin-releasing hormone and monoaminergic system genes. However, little is known about how genetic variants and life stress work to shape children’s neuroendocrine reactivity and emerging symptoms. Therefore, the aim of this thesis is to examine main effects of candidate genes and GxE on the neuroendocrine stress response and …

Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres

University of New Orleans Theses and Dissertations

Stress has been widely shown to directly influence people’s emotional and behavioral processing as well as their underlying biological systems. This project examined physiological and behavioral responses as indicators of stress and coping in the context of a psychosocial stressor in a controlled laboratory setting. We examined the association between indicators of behavioral coping and underlying physiological reactivity within participants while experiencing stress. Participants included 68 emerging adults. Physiological measures include autonomic biomarkers (e.g., heart-rate, skin conductance) at rest and during the stressor while behavioral indicators that were coded include acute verbal and non-verbal actions exhibited by participants during the …

“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 …
