Neuronal Correlates For Neuroendocrine Habituation To Repeated Stress, Sara Matovic

Electronic Thesis and Dissertation Repository

One way that the body actively responds to an impending stressor is by increasing systemic glucocorticoids through the activation of the hypothalamic-pituitary-adrenal (HPA) axis. While it is essential for short-term adaptation to stress, the sustained activation of the HPA axis during chronic stress can be detrimental and is linked to stress-related psychiatric conditions such as anxiety and depression. Therefore, it is important that the HPA axis adapts, or habituates, during chronic stress to minimize the negative consequences. Corticotropin releasing hormone (CRH) neurons in the paraventricular nucleus of the hypothalamus (PVN) function to assimilate incoming information from the stress circuitry and …

The Dynamics Of Stress And Fatigue Across Menopause: Attractors, Coupling, And Resilience, Lisa Taylor-Swanson, Alexander E. Wong, David Pincus, Jonathan E. Butner, Jennifer Hahn-Holbrook, Mary Koithan, Kathryn Wann, Nancy F. Woods

Psychology Faculty Articles and Research

Objective:

The objective of this study was to evaluate the regulatory dynamics between stress and fatigue experienced by women during the menopausal transition (MT) and early postmenopause (EPM). Fatigue and perceived stress are commonly experienced by women during the MT and EPM. We sought to discover relationships between these symptoms and to employ these symptoms as possible markers for resilience.

Methods:

Participants were drawn from the longitudinal Seattle Midlife Women's Health Study. Eligible women completed questionnaires on 60+ occasions (annual health reports and monthly health diaries) (n = 56 women). The total number of observations across the sample was 4,224. …

Social Status Modulates Restraint- Induced Neural Activity In Brain Regions Controlling Stress Vulnerability , Sahba Seddighi, Matthew A. Cooper

Haslam Scholars Projects

Understanding the cellular mechanisms that control resistance and vulnerability to stress is an important step toward identifying novel targets for the prevention and treatment of stress-related mental illness. Dominant and subordinate animals have been shown to exhibit different behavioral and physiological responses to stress, with dominants often showing stress resistance and subordinates often showing stress vulnerability. We have previously found that dominant hamsters exhibit reduced social avoidance following social defeat stress compared to subordinate hamsters, although the extent to which stress resistance in dominants generalizes to non-social stressors is unknown. In this study, dominant, subordinate, and control male Syrian hamsters …

Anger Without Agency: Exploring The Experiences Of Stress In Adolescent Girls, Elin A. Björling, Narayan B. Singh

The Qualitative Report

Although a great deal of research has measured stressful life events and stress-related symptoms in adolescents, little research has qualitatively examined the experience of stress in teens. The purpose of this study was to utilize thematic analysis to explore how teen girls described their experiences of stress. Thirty-one girls, ages 14–18, were recruited for a study examining stress and stress-related symptoms. As part of this study, they participated in an open-ended, qualitative interview about their personal experiences of stress. Themes included the mind of stress, emotionally shutting out others, and “growing out of it.” The overarching finding was that all …

Background: Key elements in the clinical practice of prevention, health and wellness are best cultivated in medical professionals during undergraduate medical training. This study explores students' self-assessed stress relative to gender, academic expectations, and level of medical training to guide development of targeted wellness interventions. Methods: In early 2012, undergraduate (M1-M4) students in four Southeastern U.S. allopathic medical schools were surveyed about health-related attitudes and behaviors. Results: A total of 575 students returned completed questionnaires. Students in the preclinical years (M1-M2), especially females, reported significantly higher stress levels. Academic expectations and satisfaction were also significantly implicated. Discussion: These findings highlight …

Age Differences In Stress And Coping: Problem-Focused Strategies Mediate The Relationship Between Age And Positive Affect, Yiwei Chen, Yisheng Peng, Huanzhen Xu, William H. O'Brien

Psychology Faculty Publications

The present study examined the different types of stressors experienced by adults of different ages, their coping strategies, and positive/negative affect. A mediation hypothesis of coping strategies was tested on the relationships between age and positive/negative affect. One-hundred and ninety-six community-dwelling adults (age range 18-89 years old) reported the most stressful situation they experienced in the past month and coping strategies. Levels of positive and negative affect in the past month were also measured. Content analysis revealed age differences in different types of stressors adults reported. Three types of coping strategies were found: problem-focused, positive emotion-focused, and negative emotion-focused coping. …

The Whole Is Not The Sum Of Its Parts: Specific Types Of Positive Affect Influence Sleep Differentially, Sarah D. Pressman, Brooke N. Jenkins, Tara L. Kraft, Heather Rasmussen, Michael F. Scheier

Psychology Faculty Articles and Research

Given the known detrimental effects of poor sleep on an array of psychological and physical health processes, it is critical to understand the factors that protect sleep, especially during times of stress when sleep particularly suffers. Positive affect (PA) arises as a variable of interest given its known associations with health and health behaviors and its ability to buffer stress. In two studies, we examined which types of PA (distinguished by arousal level and trait/state measurement) were most beneficial for sleep and whether these associations varied depending on the stress context. In Study 1, college students (N = 99) reported …

Sibrava Studies, Teaches About Stress And Anxiety, Aldemaro Romero Jr.

Publications and Research

“There’s a cliché answer that you get from a lot of folks who say, ‘Well, I’ve always been interested in people,’ and that is true, but for me I always fan- tasized about being a lawyer when I grew up.” This is how Dr. Nicholas Sibrava explains his choice of career. In fact, he envisioned himself in a courtroom, just like in the movies.

It also explains why this native of Cleveland, Ohio obtained a bachelor’s degree in both criminology and psychology. The psychology part crept up on him while taking some psych courses. “Somewhere along the way I flip-flopped …

Stress And Sleep Quality: Mediating Effects Of Social Support, Felisha L. Younkin, Elizabeth A. Axtell, Chelsea R. Anderton

The Research and Scholarship Symposium (2013-2019)

Stress is defined as the “nonspecific response of the body to any demand made upon it” (Kohn & Frazer, 1986). Stress is among the top five threats to academic performance among college students (Pettit & DeBarr, 2011). The purpose of the study was to investigate whether stress affects perceived sleep quality, as mediated by social support, and to determine whether stress levels vary based on academic major. Using ANOVA in SPSS 24, we tested three hypotheses: stress and sleep quality are negatively correlated, social support mediates the relationship between stress and sleep quality, and stress levels will vary by academic …

Information offered in the article can be used to prepare future Antarctic expedition teams to manage stressors faced while undertaking extreme journeys in the higher latitudes.

The Correlation Between Stress And The Development Of Dissociative Identity Disorder, Aviva Soibelman

The Science Journal of the Lander College of Arts and Sciences

Stress is a huge part of life. Our body responds to stress in different ways and most of the times the body overcomes the stress. There are a few incidents when the body is not capable of dealing with the stress and the toll it takes on the brain is undeniable. One result of intolerable stress is Dissociative Identity Disorder (DID) in which biopsychology comes to life, as we see how the body is affected by psychology, and vice versa. The mediators that help the body adapt to stressors become detrimental when a person faces trauma or chronic stress. Glucocorticoids, …

Stress Reducing Effects Of Indoor Plants In A Classroom Setting, Laura Tennant

Student Research Posters

Previous research has demonstrated that natural views and access to plants appear to have significant beneficial effects on individuals (Relf, 1992). Studies of green views out of a classroom window showed significant reductions in students’ mental fatigue (Li & Sullivan, 2016), and studies of indoor plants in hospital settings showed stress reduction and increased healing rates in patients (Ulrich, 1984). Indoor plants in the workplace demonstrated improved employee performance (Kweon, Ulrich, Walker, & Tassinary, 2008). However, there have been few studies examining the impact indoor plants might have in a classroom setting. This study used an experimental design to measure …

Assessing Parent Invovlment In Applied Behavior Analysis Treatment For Children With Autism, Krista Marie Clancy

Wayne State University Dissertations

The purpose of this study was to compare two groups of parents whose children participated in ABA on their levels of stress, self-efficacy, treatment acceptability, and parents’ level of involvement in their children’s treatment, and to assess variables that may explain variance in parent involvement. Parents in the treatment group participated in a voluntary parent training (n=18) and the comparison group were parents who elected not to participate in the voluntary training (n=22). This was a quasi-experimental design study where parents and their therapists completed a survey regarding parents’ involvement in their children’s treatment programs. Additional parent measures collected as …

Towards A Not Obtrusive Low Cost Biosystem To Assess Risk Perception In Workplace Through Stress Detection, Emanuele Bellini, Serena Benevenuti, Chiara Batistini

H-Workload 2017: Models and Applications (Works in Progress)

The main aim of the article is to build a method to assess risk perception in real time in order to early detect and prevent risk behaviors and possible human errors. To this end, the relation between mental workload and stress as critical factors affecting risk perception has been investigated. In particular the mental-physical activation generated by an increment of the workload has the effect of reducing the resources needed to perceive risk increasing the worker vulnerability. The complexity of the stress phenomenon suggested the adoption of an integrated view. The Functional Model has been adopted to for its holistic …

The Impact Of Stress On Steroid Hormones And Cue Reactivity In Smokers And Gamblers, Stephanie Elaine Wemm

Legacy Theses & Dissertations (2009 - 2024)

Addictions, both substance and behavioral, have been conceptualized as having similar biopsychosocial processes with different opportunistic expressions (Shaffer et al., 2004). Biological processes such as the hormonal response to stress as measured by cortisol, dehydroepiandrosterone (DHEA), and the ratio of the DHEA/cortisol may be among the variables underlying the disposition to develop an addictive disorder, regardless of whether it is a substance-based or a so-called behavioral addiction. The current study aimed to examine whether physiological and psychological reactions to stress are similar in high-frequency smokers and gamblers. The subjective (urges, cravings) and physiological responses (skin conductance and heart rate) of …
