Serotonin Transporter Genotype Modulates Hpa Axis Output During Stress: Effect Of Stress, Dexamethasone Test And Acth Challenge, Andrea N. Sorenson, Erin C. Sullivan, Sally P. Mendoza, John P. Capitanio, James Dee Higley

Faculty Publications

Background—Studies show that the hypothalamic–pituitary–adrenal (HPA) axis is dysregulated in depression. Some studies suggest that variation in the serotonin transporter genotype (hereafter 5HTT) modulates both risk for depression and psychopathological HPA axis responsiveness. Rhesus monkeys are well suited to model such relationships. Rhesus macaque models of human psychopathology have assessed the effect of the serotonin transporter (rh5HTT) on levels of cortisol in stressed subjects. These studies show that that under conditions of stress, heterozygous females (Ls) reared under adversity exhibit high levels of cortisol. Studies have not to our knowledge, however, assessed the potential additive effect on the cortisol response …

The Relation Of Anxiety, Depression, And Stress To Binge Eating Behavior, Diane L. Rosenbaum

Dissertations

Binge eating is an impairing and prevalent problem. Theories of binge eating suggest negative affect is of primary importance in the development and maintenance of binge eating behavior. To date, investigations of binge eating have often examined depression, however relatively little is known about other psychological factors. The current study aimed to extend the literature by examining several psychological factors in relation to binge eating behavior. Specifically, the relation between binge eating behavior and three psychological factors, depression, anxiety and stress, were examined. Data were collected via online surveys from a community sample of men and women of diverse backgrounds. …

The Effects Of Community Support On Posttraumatic Growth Outcomes For Parents Of Children With Chronic Illness, Colleen Gannon

Theses and Dissertations

Parents of children with chronic illnesses face many stressors on multiple fronts as a result of their child's care needs. Posttraumatic growth is positive psychological outcomes of stress for those who have experienced a traumatic event, such as the diagnosis of a child with a chronic illness. While much is known about the challenges of caring for a child with a chronic condition, there is little research on these parent's growth outcomes. Of the research that does exist, much focuses on internal predictors of posttraumatic growth, such as personality characteristics. The purpose of this study is to begin to investigate …

Motor Variability During Sustained Contractions Increases With Cognitive Demand In Older Adults, Marnie Lynn Vanden Noven, Hugo M. Pereira, Tejin Yoon, Alyssa A. Stevens, Kristy A. Nielson, Sandra K. Hunter

Psychology Faculty Research and Publications

To expose cortical involvement in age-related changes in motor performance, we compared steadiness (force fluctuations) and fatigability of submaximal isometric contractions with the ankle dorsiflexor muscles in older and young adults and with varying levels of cognitive demand imposed. Sixteen young (20.4 ± 2.1 year: 8 men, 9 women) and 17 older adults (68.8 ± 4.4 years: 9 men, 8 women) attended three sessions and performed a 40 s isometric contraction at 5% maximal voluntary contraction (MVC) force followed by an isometric contraction at 30% MVC until task failure. The cognitive demand required during the submaximal contractions in each session …

Mood And Experience: Effects Of Ostracism On Diathesis Activation, Rachel Archer

Mahurin Honors College Capstone Experience/Thesis Projects

The stress-diathesis model is a well-known but little-tested theory which states that people can possess diatheses, or vulnerabilities, to certain mental disorders such as depression or anxiety. These diatheses are activated when a person is under stress. This study examined how ostracism as a temporary stressor can trigger existing diatheses and cause increases in depression symptoms among at-risk people. Theory suggests that ostracism is likely to trigger symptoms of depression in at-risk people. This study is an extension of a study conducted by Luxton, Ingram, and Wenzlaff (2006) in which people with naturally varying levels of diathesis factors were exposed …

The Use Of Stress Reduction Techniques In Nursing Education, Jennifer S. Bauer

Evidence-Based Practice Project Reports

Stress is a complex phenomenon that has significant effects on students which may disturb their physiological, psychological, and spiritual health and well-being. Nursing students have been identified to be at high risk for stress during their education. Stress can arise from new clinical experiences, academic load, and personal stressors (Jones & Johnston, 2006). This increase in stress can lead to the student’s inability to assimilate and learn within the classroom and clinical settings. A review of the literature provided evidence that reported a positive relationship between guided imagery and a decrease in stress and anxiety. This evidence-based practice (EBP) project …

A Mindfulness-Based Intervention To Reduce Stress In Undergraduates., Dirk Anthony Dorsel

College of Arts & Sciences Senior Theses

This study piloted a mindfulness-based intervention to reduce stress in university undergraduates, and explore effects on psychological and biological indicators of stress. Mindfulness is “the awareness that emerges through paying attention on purpose, in the present moment and non-judgmentally to the unfolding of experience moment-by-moment” (Kabat-Zinn, 1994). The one week mindfulness intervention used audiobased mindfulness tracks recorded by Clinical Psychologist Paul Salmon. These tracks taught the basics of mindfulness. Participants were asked to listen to the tracks for 30 minutes a day for five days of the intervention. Perceived stress, self-reported anxiety, self-reported depression, heart rate and skin conductance were …

The Relationship Between Work Status And Grade Point Average, Lauren Kennington, Verdina Pilipovic

Undergraduate Psychology Research Methods Journal

There is a fine line between wanting to succeed and being able to succeed. There are certain factors that one has imaged when the visions of success come along. These images include the wide range of having a good job, being able to provide for individual wants and needs, as well as continuing to have a social life. Being a student is reflected on these visions of success by how well one’s grade point average is maintained, along with his or her stress level of working and going to school, and even being able to sleep and still find time …

Stress And Coping As A Function Of Experience Level In Collegiate Flight Students, Jennifer Kirschner, John Young, Richard Fanjoy

Journal of Aviation Technology and Engineering

Aviation as an industry requires a high degree of precision at all times. Large amounts of stress have been known to decrease performance to undesirable levels. While stress reactions and the coping skills used after encountering stressful situations differ from person to person, generalities can be made by comparing differences between groups. A large number of pilot applicants receive initial training within a university flight program each year. In order to better understand the perceived stress level and the coping skills used by these students, the current research project administered a perceived stress test and a coping skills inventory to …

Openness, Neuroticism, Conscientiousness, And Family Health And Aging Concerns Interact In The Prediction Of Health-Related Internet Searches In A Representative U.S. Sample, Tim Bogg, Phuong T. Vo

Psychology Faculty Research Publications

Recent estimates suggest 60 % of the U.S. adult population uses the Internet to find health-related information. The goal of the present study was to model health-related Internet searches as a function of an interdependent system of personality adaptation in the context of recent health and aging-related concerns. Assessments of background factors, Big Five personality traits, past-month health and aging-related concerns, and the frequency of past-month health-related Internet searches (via Google, Yahoo, AOL, Bing, or some other search engine) were obtained from a representative U.S. sample (N = 1,015). Controlling for background factors, regression analyses showed more frequent health-related …

Workload Transitions And Stress: Changes Over Time, Erik G. Prytz

Psychology Theses & Dissertations

Workload transitions are situations where operators are suddenly confronted with levels of workload substantially different from previously established levels. Workload transitions may affect the operators' state of stress and coping behaviors but previous research has not conclusively demonstrated the nature of those. The first goal of the current work was to investigate the discrepant findings of the previous literature. Two experiments were conducted where participants were asked to perform a digit detection task that suddenly shifted between low and high event rates (i.e., low and high workload, respectively). The first experiment used a large magnitude transition that resulted in a …

Understanding And Treating The Psychosocial Consequences Of Infertility, Arthur L. Greil, Lone Schmidt, Brennan Peterson

Marriage and Family Therapy Faculty Books and Book Chapters

Psychological distress and infertility are linked in a complex pattern, such that distress may be a cause of infertility and reduce the probability of achieving a pregnancy at the same time that infertility may be a cause of psychological distress. Although infertile women are not more likely to be characterized by psychopathology, they are more likely to experience higher levels of distress than comparison groups. Infertile men also experience psychological distress, but women experience more infertility distress than men. Both infertility and its treatment are stressors putting a heavy psychological strain on couple relationships. Whereas there is general agreement about …

A Brief History Of Mind-Body Medicine, Elliot S. Dacher

International Journal of Transpersonal Studies

From its earliest sources the medical tradition has recognized the causal role of the interface of mind and body in health and disease. Cultural and historical circumstances have determined the degree to which each of these two key factors are emphasized. In modern times we are emerging from an exclusive materialistic emphasis on biology to a renewed acceptance and understanding of the role of the mind and consciousness in health and disease. This re-balancing of the two great forces of healing can be traced to a progressive expansion of knowledge in the fields of stress, past-traumatic stress, biofeedback, cognitive and …

Links Between White Matter Microstructure And Cortisol Reactivity To Stress In Early Childhood: Evidence For Moderation By Parenting., Haroon I Sheikh, Marc F Joanisse, Sarah M Mackrell, Katie R Kryski, Heather J Smith, Shiva M Singh, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

Activity of the hypothalamic-pituitary-adrenal axis (measured via cortisol reactivity) may be a biological marker of risk for depression and anxiety, possibly even early in development. However, the structural neural correlates of early cortisol reactivity are not well known, although these would potentially inform broader models of mechanisms of risk, especially if the early environment further shapes these relationships. Therefore, we examined links between white matter architecture and young girls' cortisol reactivity and whether early caregiving moderated these links. We recruited 45 6-year-old girls based on whether they had previously shown high or low cortisol reactivity to a stress task at …

Understanding The Role Of Nutritional Stress In The Adult And Developing Zebra Finch, Jessica Bayley Thompson

Wayne State University Dissertations

Songbirds are particularly susceptible to stress during the sensitive period for song learning. Thus the developmental stress hypothesis (DSH) proposes that adult song reflects a male's early life environment during this period. Nutritional stress (NS) has been shown to cause deficits in song learning and adult song output that are salient to females. Female song birds consistently prefer control males over those raised under NS, yet the effects NS on females are still unclear. The hypothalamic-pituitary-adrenal axis (HPA) has been implicated in this process. However, evidence directly linking HPA functioning to the deficits due to NS have inconsistently shown elevations …

Work Stress, Meaning, And Values: A Study Of Intellectual Disability Support Staff, Jennifer Marie Ladner-Graham

Electronic Theses and Dissertations

Employees who work with individuals with intellectual disabilities report high levels of work-related stress. Staff stress is associated with a variety of negative outcomes, such as poor psychological health, job burnout, and high turnover rates. The current study investigated the relationship between staff stress and negative outcomes. Specifically, this study examined whether positive psychology concepts such as perceived meaning in life and values moderated the relationship between staff stress and poor psychological health, job search/intention to leave the job, and use of sick leave. Participants included staff members from an inpatient facility for people with intellectual disabilities located in North …

The Roles Of Social Support And Job Meaningfulness In The Disturbing Media Exposure-Job Strain Relationship, Hung T. Hoang

All Graduate Theses, Dissertations, and Other Capstone Projects

This study examined the relationship between exposure to disturbing media and a number of strain outcomes. Past research suggests that individuals exposed to disturbing media report symptoms of secondary traumatic stress and burnout (Perez, Jones, Englert, & Sachau, 2010). This relationship was further explored in the current study. Additionally, the current study explored the roles of social support and job meaningfulness in the work place, as past research suggests that support and meaningfulness may help to mitigate the negative outcomes typically found among workers exposed to traumatic stressors (Britt, Adler, & Barton, 2001; Halbesleben, 2006; Morales, 2012; Stephens & Long, …

Influences Of Maternal Stress During Pregnancy On The Epi/Genome: Comparison Of Placenta And Umbilical Cord Blood, Jia Chen, Qian Li, Alexender Rialdi, Elana Mystal, Jenny Ly, Jackie Finik, Taira Davey, Luca Lambertini, Yoko Nomura

Publications and Research

Background: Maternal stress during pregnancy is one of the major adverse environmental factors in utero that is capable of influencing health outcomes of the offspring throughout life. Both genetic and epigenetic processes are susceptible to environmental insults in utero and are potential biomarkers of the experienced environment including maternal stress.

Methods: We profiled expression level of six genes in hypothalamic pituitary adrenal (HPA) axis functioning (HSD11B2, SLC6A4, NR3C1, NR3C2, CRHR1 and CRHR2), two imprinted genes (IGF2 and H19) and one neurodevelopmental gene (EGR1), from 49 pairs of placenta and umbilical cord blood (UCB) samples from a birth cohort. We also …

Challenge Accepted: Self-Enhancement Through The Pursuit Of Difficulty, Julie Anne Steinke

Browse all Theses and Dissertations

Individual resilience is popular topic whereby researchers attempt to identify characteristics of individuals who react positively to stress. However, such research uses a reactionary approach, attempting to characterize successful individuals after they experience adversity and does not explain why some individuals proactively seek out challenging circumstances. Pursuing challenge is a new construct that explains why individuals proactively increase stress as a strategic mechanism for developmental purposes. I developed and validated a measurement tool for pursuing challenge in multiple studies. Additionally, I explored relationships between pursuing challenge and similar constructs (e.g., grit, proactive personality, and self-efficacy), as well as the extent …

Inspiring Change: Exercise Self-Efficacy, Dispositional Optimism, And Perceived Stress In College Seniors, Joshua M. Garrin

Walden Dissertations and Doctoral Studies

Prohealth competencies, positive outcome expectancies, and adaptive stress appraisals have profound implications for the real-world transition of college seniors—a population for which engagement in physical activity reflects a preeminent concern. Prior studies on exercise self-efficacy (ESE), dispositional optimism (DO), perceived stress (PS), and physical activity have yielded inconclusive evidence of the emergent psychosocial challenges encountered during the final year of the college experience. Using a triadic framework of self-efficacy, attribution, and cognitive appraisal theories, this crosssectional, quantitative study was conducted using a web survey to examine (a) the impact of physical activity level on ESE, DO, and PS; (b) the …

Reducing Depression During The Menopausal Transition: Study Protocol For A Randomised Controlled Trial, Osvaldo P. Almeida, Kylie Marsh, Leon Flicker, Martha Hickey, Andrew Ford, Moira Sim

Research outputs 2014 to 2021

Background: The menopausal transition (MT) is a biological inevitability for all ageing women that can be associated with changes in mood, including depressive symptoms. There is tentative evidence that women who develop depression during the MT have greater risk of subsequent depressive episodes, as well as increased health morbidity and mortality. Thus, preventing depression during the MT could enhance both current and the future health and well-being of women. This study aims to test the efficacy of a client-centred health promotion intervention to decrease the 12-month incidence of clinically significant symptoms of depression among women undergoing the MT.Methods/Design: This randomised …

An Alternative To The Traditional Cold Pressor Test: The Cold Pressor Arm Wrap, Anthony J. Porcelli

Psychology Faculty Research and Publications

Recently research on the relationship between stress and cognition, emotion, and behavior has greatly increased. These advances have yielded insights into important questions ranging from the nature of stress' influence on addiction1 to the role of stress in neural changes associated with alterations in decision-making^2,3. As topics being examined by the field evolve, however, so too must the methodologies involved. In this article a practical and effective alternative to a classic stress induction technique, the cold pressor test (CPT), is presented: the cold pressor arm wrap (CPAW). CPT typically involves immersion of a participant's dominant hand in ice-cold …

Coupling Of The Hpa And Hpg Axes, Andrew Dismukes

LSU New Orleans Theses and Dissertations

The Hypothalamic-Pituitary-Adrenal (HPA) and –Gonadal (HPG) axes have been considered mutually inhibitory; however, emerging evidence supports the proposition that this might not necessarily be the case. This idea is termed “coupling,” in which the HPA-HPG axis are mutually activated or deactivated. Coupling is examined across three data sets with different time-courses of stress exposure, and results demonstrate HPA-HPG co-activation occurs. Furthermore, stress exposure influences this relationship. The discussion shows how it is physiologically possible to have positive coupling or co-activation between these axes according to complex regulatory feedback systems and overlapping neural structures. Findings are interpreted developmentally, because adolescence may …

Pilates, Mindfulness And Somatic Education, Karen Caldwell, Marianne Adams, Rebecca Quinn, Mandy Harrison, Jeffrey M. Greeson

College of Science & Mathematics Departmental Research

The Pilates Method is a form of somatic education with the potential to cultivate mindfulness – a mental quality associated with overall well-being. However, controlled studies are needed to determine whether changes in mindfulness are specific to the Pilates Method or also result from other forms of exercise. This quasi-experimental study compared Pilates Method mat classes and recreational exercise classes on measures of mindfulness and well-being at the beginning, middle and end of a 15 week semester. Total mindfulness scores increased overall for the Pilates Method group but not for the exercise control group, and these increases were directly related …

Early Exposure To Traumatic Stressors Impairs Emotional Brain Circuitry, Robert H. Paul, Mayuresh S. Korgaonkar, Cassandra Antees, Leanne M. Williams

Psychology Faculty Works

Exposure to early life trauma (ELT) is known to have a profound impact on mental development, leading to a higher risk for depression and anxiety. Our aim was to use multiple structural imaging methods to systematically investigate how traumatic stressors early in life impact the emotional brain circuits, typically found impaired with clinical diagnosis of depression and anxiety, across the lifespan in an otherwise healthy cohort. MRI data and self-reported histories of ELT from 352 healthy individuals screened for no psychiatric disorders were analyzed in this study. The volume and cortical thickness of the limbic and cingulate regions were assessed …

Mental Illness Prevention: Exploring Effective Coping Strategies For School-Aged Children, Julie-Anne Mccarthy

Psychology Graduate Publications

Anxiety Disorders are the most prevalent mental illnesses in Western society, affecting the population in multiple ways. Onset for many anxiety disorders is as early as childhood or adolescence. The earlier the onset, the more chronic or severe it may be; it is important to focus on preventing anxiety disorders before they are developed. Research has shown that adaptive coping strategies can work as a mediator between stress and mental health. The current study explored effective coping strategies for young children in the general population, in an effort to further expand our knowledge about coping in children, and increase the …

Using A Resiliency Framework To Examine Natural Mentoring Relationships And The Coping Efficacy As Buffers Of The Negative Impact Of Stressors On Academic Outcomes In Urban, Low-Income Ethnic Minority Youth, Rachel M. Feuer

College of Science and Health Theses and Dissertations

This paper used Resiliency theory to examine natural mentoring and coping efficacy as protective factors that may buffer the negative impact of stressors on academic and psychosocial outcomes in urban, low-income, Latino youth. Research has demonstrated that natural mentoring may serve a protective role for youth who are experiencing high levels of stressors, and that coping efficacy may correlate with positive outcomes. The present study used Structural Equation Modeling to test the compensatory and protective factors models of resilience to examine the ways in which stress, coping efficacy and natural mentoring interact to predict a variety of academic outcomes for …
