A Role Perspective Of Workplace Procrastination, Boran Li
A Role Perspective Of Workplace Procrastination, Boran Li
Legacy Theses & Dissertations (2009 - 2024)
Although procrastination has been studied for over twenty years in the field of psychology, knowledge of workplace procrastination, developed from general procrastination, remains limited. Drawing from role theory, the current study aims to examine the positive relationship between role ambiguity and workplace procrastination through stress. It further examines the moderating role of work self-efficacy on the stress-procrastination relationship, such that higher work self-efficacy attenuates the positive relationship between stress and procrastination. Results from experimental data on 119 participants revealed that neither role ambiguity nor stress directly affects workplace procrastination, but individuals who have a higher level of self-efficacy at work …
Methamphetamine-Induced Modulation Of Anxiety/Depressive-Like Behaviors And Hpa Axis Output : Contributing Factors Within Stress Associated Brain Regions, Jason Jacobskind
Methamphetamine-Induced Modulation Of Anxiety/Depressive-Like Behaviors And Hpa Axis Output : Contributing Factors Within Stress Associated Brain Regions, Jason Jacobskind
Legacy Theses & Dissertations (2009 - 2024)
Methamphetamine (MA) is a psychostimulant drug of addiction that induces a wide range ofeffects. Among its many side effects is the potentiation of cellular, physiological, and behavioral changes in the stress response system. Upon exposure, the hypothalamic-pituitary-adrenal (HPA) axis is initiated. This process entails many factors. Receiving input from other brain regions, the paraventricular nucleus (PVN) of the hypothalamus secretes corticotropin-releasing factor (CRF) and arginine vasopressin into the anterior pituitary gland. These together stimulate the synthesis and release of adrenocorticotropic hormone, which circulates via the blood stream to cause the release of glucocortoicoids, the stress hormone (CORT). Binding of glucocorticoids …
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 …
Big, Black, And Strong : Does Identification With The Strong Black Woman Archetype Strengthen The Association Between Racism-Related Stress And Emotional Eating?, Shantel Lorraine Powell
Big, Black, And Strong : Does Identification With The Strong Black Woman Archetype Strengthen The Association Between Racism-Related Stress And Emotional Eating?, Shantel Lorraine Powell
Legacy Theses & Dissertations (2009 - 2024)
Despite extensive research on the adverse impact of racism-related stressors on the health and well-being of people of color (Broman, Mavaddat, & Hsu, 2000; Carter, 2007; Klonoff, Landrine, & Ullman, 1999; Noh & Kaspar, 2003; Pieterse, Carter, & Ray, 2013; Utsey & Payne, 2000), little is known about the influence of racism-related stressors on the eating behaviors of Black women. The present study extended the limited literature on this topic by examining the possible contribution of cultural attitudes associated with the Strong Black Women archetype on the relation between racism-related stressors and emotional eating behaviors.
The Evocative Effects Of Child Temperament On Parenting Stress And Behaviors, Laura Welch
The Evocative Effects Of Child Temperament On Parenting Stress And Behaviors, Laura Welch
Legacy Theses & Dissertations (2009 - 2024)
Despite recognition that parents contribute to child development, much remains to be clarified about ways child characteristics shape parents’ behaviors. For example, temperamental characteristics such as negative affectivity elicit more parenting stress (Oddi, Murdock, Vadnais, Bridgett, & Gartstein, 2013) and less effective parenting behaviors (Laukkanen, Ojansuu, Tolvanen, Alatupa, & Aunola, 2014). On the other hand, children’s effortful control is known to reduce psychological risks associated with negative affectivity (Gartstein, Putnam, & Rothbart, 2012) yet no studies have investigated whether this may consequently reduce parenting stress. Furthermore, stressed parents are more likely to engage in harsh parenting strategies (Martorell & Bugental, …
Stress And Support In Health Service Psychology Students : Predictors Of Burnout And Vigor, Dylan Alexander Corp
Stress And Support In Health Service Psychology Students : Predictors Of Burnout And Vigor, Dylan Alexander Corp
Legacy Theses & Dissertations (2009 - 2024)
Students in health service psychology (HSP) training programs (i.e., doctoral programs in clinical, counseling, or school psychology) have reported experiencing greater burnout (i.e., energetic exhaustion) and lower vigor (i.e., energetic arousal) than typical workers. Given that greater burnout and lower vigor are associated with negative outcomes like poor health and client care, the purpose of the present study was to understand burnout and vigor in HSP students. Specifically, the present study sought to test the Conservations of Resources theory of stress (CORT) by replicating previous findings that threatening work-related stress and the supervisory working alliance (SWA) predicted HSP students’ burnout …
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
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; …
Relationships Among Community Violence Exposure, Physiological Stress Responses, And Resilience In Children, Cheryl Kayleen Best
Relationships Among Community Violence Exposure, Physiological Stress Responses, And Resilience In Children, Cheryl Kayleen Best
Legacy Theses & Dissertations (2009 - 2024)
This study seeks to understand how resilience is affected by physiological stress responses in the context of community violence. The hypothesis of this paper is that physiological indicators of salivary cortisol and salivary alpha-amylase (sAA) would moderate a relation between community violence exposure in children and the expression of resilience. Forty-nine children aged nine to twelve were recruited from an after-school program located in an area with high levels of community violence. Results supported our hypothesis for sAA as a moderator of the relation between community violence and resilience, such that at high sAA reactivity, a negative relation exists between …
The Impact Of Stress On Steroid Hormones And Cue Reactivity In Smokers And Gamblers, Stephanie Elaine Wemm
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 …
How Do Students Appraise And Cope With Episodic Stressors : A Four-Wave Study, Jingyi Huang
How Do Students Appraise And Cope With Episodic Stressors : A Four-Wave Study, Jingyi Huang
Legacy Theses & Dissertations (2009 - 2024)
Stress is a dynamic process. For episodic task-related stressors, four stages – the anticipatory stage, the confronting stage, the waiting stage, and the outcome stage – can be defined. Using a student sample, in this study I employed a longitudinal design to examine how exam-related coping unfolds across these stages, how perceived control predicts the use of coping strategies, and how personality moderates the relations between perceived control and the selection of coping strategies. The results show that across time behavioral disengagement and substance use had a convex trajectory, and that seeking of emotional social support and positive reinterpretation had …
Does Self-Care Moderate The Relation Of Stress To Quality Of Life Of Female Doctoral Students In Professional Psychology?, Erin Elizabeth Ayala
Does Self-Care Moderate The Relation Of Stress To Quality Of Life Of Female Doctoral Students In Professional Psychology?, Erin Elizabeth Ayala
Legacy Theses & Dissertations (2009 - 2024)
Increasing numbers of women are pursuing doctoral degrees in psychology, and the stress of being a female doctoral student can create a risk for aversive consequences (e.g., ineffective clinical work, impaired competence). Psychologists lack an understanding of the extent to which women can protect themselves from undue stress in professional psychology programs by engaging in self-care. The lack of a comprehensive framework for this phenomenon calls for the need to apply and test the Health Promotion Model to the experience of women in professional psychology programs. The current investigation assessed the extent to which self-care activities would moderate the negative …
Predictors Of Burnout And Vigor Among Clinical And Counseling Psychology Doctoral Students, Brett Swords
Predictors Of Burnout And Vigor Among Clinical And Counseling Psychology Doctoral Students, Brett Swords
Legacy Theses & Dissertations (2009 - 2024)
Work-related burnout, although connected to many negative outcomes (Kahill, 1988), has not been thoroughly studied in the graduate student population. The goal of the present study was to examine burnout and vigor among clinical and counseling psychology doctoral students. Based on conservation of resources theory (Hobfoll & Freedy, 1993; Hobfoll & Shirom, 2001), five variables were selected as predictors of burnout and vigor: two types of general work-related stress (i.e., pressure and threat; Stanton et al., 2001), the supervisory working alliance, financial strain, and conflict with others in the workplace. Seven hypotheses were tested about the expected relation between burnout …
Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam
Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam
Legacy Theses & Dissertations (2009 - 2024)
Attempts to define mindfulness in the clinical and psychological sciences have been marred by contradictions, inconsistencies, and controversies. In this wait-list (WL) controlled mindfulness meditation training (MMT) study, the efficacy and potential mechanisms of MMT was tested in a community sample with undiagnosed, but significant, symptoms of anxiety, depression, and stress. In a pre/post design, which also included 3 month follow-up, participants completed self-report measures, participated in a psychosocial stress task (before and after which they completed self-report mood questionnaires and had physiological and salivary neuroendocrine markers collected), and completed an emotional attentional blink paradigm. Compared to WL (n = …
Prospective Effects Of Temperamental Reactivity, Emotion Dysregulation, And Stress On Risk For Anxiety And Depression In Elementary School-Age Children, Jeremy Kyle Fox
Prospective Effects Of Temperamental Reactivity, Emotion Dysregulation, And Stress On Risk For Anxiety And Depression In Elementary School-Age Children, Jeremy Kyle Fox
Legacy Theses & Dissertations (2009 - 2024)
Temperamental reactivity and emotion dysregulation are both considered important vulnerability factors in the development of childhood anxiety and depression. Little is known, however, about how these emotional processes work together to shape developmental pathways to internalizing difficulties.
Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn
Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn
Legacy Theses & Dissertations (2009 - 2024)
This study tests the hypothesis that long–term experience of Apostolic Pentecostal glossolalia or “speaking in tongues” reduces the reactivity of biological stress response to normal or "daily" stressors. Glossolalia is a form of religious dissociation. Dissociation is a universal capacity often conflated with “trance.” It refers to the partitioning of awareness associated with a variety of cross–cultural forms, from daydreaming and denial to possession trance, shamanic spirit journeys, and dissociative identity disorder. Dissociation is believed to reduce or filter stress by mediating evaluation of potential stressors and reactivity of the mechanisms of biological stress response. Previous studies have examined these …
