Influences Of Chronic Stress On Irritable Bowel Syndrome, Anxiety, Depression, And The Microbiome, Julia A. Semaan
Influences Of Chronic Stress On Irritable Bowel Syndrome, Anxiety, Depression, And The Microbiome, Julia A. Semaan
Masters Theses
IBS effects approximately 5% of the world’s population with symptoms ranging from unexplainable constipation to daily abdominal pain. Though treatment options are available and have been proven beneficial for certain individuals, discovering the root cause of IBS has been difficult to accomplish due to the variety of symptoms that differ from case to case. This study aims to increase understanding of the influence that chronic stress has on irritable bowel syndrome, anxiety, depression, and the microbiome in the college-age population since this group is likely to experience daily stressors, anxiety- and depressive-like thoughts, as well as IBS symptoms. Current research …
Social Dominance Alters Stress-Induced Neural Activity And Generates Individual Differences In Stress Vulnerability, Jenna Lee Laymon
Social Dominance Alters Stress-Induced Neural Activity And Generates Individual Differences In Stress Vulnerability, Jenna Lee Laymon
Masters Theses
Identifying the physiological and behavioral mechanisms that underlie stress vulnerability is a crucial step toward identifying novel targets for the prevention and treatment of stress-related disorders. Social status is a key environmental factor that contributes to individual variations in stress vulnerability. In particular, achieving a subordinate social status has been shown to produce susceptibility to anxiety-like and depressive-like behavior. In this project, our aim was to identify neural ensembles regulating how dominance status modulated stress-induced changes in avoidant behavior in male and female Syrian hamsters. Using a viral vector that codes for robust activity marker (RAM), we investigated whether stress-induced …
Covid Fears And Social Anxiety In College Students, Clayton Crozier
Covid Fears And Social Anxiety In College Students, Clayton Crozier
Masters Theses
The COVID-19 pandemic has been associated with numerous negative mental health outcomes such as social anxiety, and lead to a great deal of uncertainty. Intolerance of Uncertainty is a relatively new concept in the psychology literature and has begun to be studied in the context of anxiety. Literature has found a positive correlation between Intolerance of Uncertainty and several types of social anxiety. With these findings, researchers have begun to examine the COVID-19 pandemic to see how Intolerance of Uncertainty affects people’s mental health during the pandemic. Intolerance of Uncertainty may be a mediator between social anxiety and the fears …
Relationships Between Postpartum Anxiety, Breastfeeding Self-Efficacy, And Breastfeeding Exclusivity, Rachel Eichholtz
Relationships Between Postpartum Anxiety, Breastfeeding Self-Efficacy, And Breastfeeding Exclusivity, Rachel Eichholtz
Masters Theses
Background
Though several important barriers to exclusive breastfeeding (EBF) have been identified, the relationship between postpartum anxiety and EBF remains inadequately explored.
Objective
The objective of this study was to determine if there was a significant relationship between postpartum anxiety and EBF and, if so, determine if breastfeeding self-efficacy moderated this relationship.
Methods
This was a cross-sectional, online survey. Eligibility criteria: mothers (at least 18 years of age), with an infant (aged 4-24 weeks), and who had provided breastmilk at least once in the previous two weeks. The survey instrument included demographic questions and three scales: the EPDS (Edinburgh Postpartum …
Sexual Experiences And Association With Depression And Anxiety Among Sexual Minority Women, Brie Engelbrecht
Sexual Experiences And Association With Depression And Anxiety Among Sexual Minority Women, Brie Engelbrecht
Masters Theses
Depression and anxiety are among the most prevalent forms of mental illness in the U.S, affecting an estimated 18% of the population. Recent studies have shown that sexual minority women may undergo sexual experiences that affect their risk of anxiety and depression. However, prior studies of this association are sparse and have largely been conducted among sexual majorities and have yet to examine differences between vulnerable sexual orientation groups. Therefore, we evaluated the relationship between sexual experiences (i.e., sexual assertiveness, sexual self-efficacy, and outness) and anxiety and depression among young sexual minority women in a cross-sectional study (N=328) from the …
The Human Intruder Test: An Anxiety Assessment In Rhesus Macaques (Macaca Mulatta), Emily J. Peterson
The Human Intruder Test: An Anxiety Assessment In Rhesus Macaques (Macaca Mulatta), Emily J. Peterson
Masters Theses
The human intruder test (HIT) is a noninvasive tool widely used for assessing anxiety in rhesus macaques (Macaca mulatta). This thesis explores the HIT procedure and applies it to a population of monkeys with a self-injurious behavioral pathology. Individual variation on this test can be used to assess anxiety and temperament. The first experiment of this thesis applied two different procedures of the HIT to 17 monkeys at UMass. Monkeys displayed little response to the intruder, and no significant differences were detected for the two procedures. To determine whether these responses were unique to the UMass monkeys, their …
