Understanding Stress Reactivity In Schizophrenia, Mary Vertinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The role of stress has long been recognized in schizophrenia; several theories have identified the role of stress as an important factor in the etiology of schizophrenia. A handful of studies have used laboratory psychosocial stressors to examine cortisol stress response in schizophrenia; the results obtained have consistently suggested that the stress response is attenuated in people with schizophrenia. Present study set out to examine stress responsivity in schizophrenia relative to healthy controls. A laboratory stress test was used to investigate cortisol response, heart rate and task appraisal in a sample of 17 healthy controls and 16 men diagnosed with …

Mindfulness And Acceptance-Based Trainings For Fostering Self-Care And Reducing Stress In Mental Health Professionals: A Systematic Review, Myriam Rudaz, Michael P. Twohig, Clarissa W. Ong, Michael E. Levin

Psychology Faculty Publications

This review summarizes the effectiveness of Mindfulness-Based Stress Reduction (MBSR), Mindfulness-Based Cognitive Therapy (MBCT), Mindful Self-Compassion (MSC), and Acceptance and Commitment Therapy (ACT) to foster self-care and reduce stress in mental health professionals. Twenty-four quantitative articles from PsycInfo and PubMed were identified that focused on mindfulness, self-compassion, psychological flexibility, stress, burnout, or psychological well-being. All MBSR and MBCT studies lacked active control conditions, but some of the ACT studies and one MSC study included an active control. Most studies support evidence that all training programs tend to improve mindfulness and some also self-compassion. In addition, psychological flexibility was measured in …

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

Jeffrey M. Greeson

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 …

Stress-Induced Changes In The Expression Of Monocytic Β2-Integrins: The Impact Of Arousal Of Negative Affect And Adrenergic Responses To The Anger Recall Interview, Jeffrey M. Greeson, James G. Lewis, Karen Achanzar, Eugene Zimmerman, Kenneth H. Young, Edward C. Suarez

Jeffrey M. Greeson

Adhesion of circulating monocytes to the vascular endothelium is one of the earliest steps in the development of atherosclerosis. This leukocyte-to-endothelium interaction is mediated in part by β2-integrins, a group of cell adhesion molecules that bind to endothelial ligands. Given the significance of this interaction to atherogenesis, we examined the effects of stress, operationalized as the arousal of negative affect (NA) and cardiovascular and catecholamine responses to the Anger Recall Interview (ARI), on the expression of LFA-1 (CD11a), Mac-1 (CD11b) and p150/95 (CD11c) on circulating monocytes (CD14+). Subjects were 173 healthy, nonsmoking men and women (60% men, 40% minorities, aged …

Hair Cortisol As A Biomarker Of Stress In Mindfulness Training For Smokers., Simon B Goldberg, Alison R Manley, Stevens S Smith, Jeffrey M Greeson, Evan Russell, Stan Van Uum, Gideon Koren, James M Davis

Jeffrey M. Greeson

OBJECTIVES: Stress is a well-known predictor of smoking relapse, and cortisol is a primary biomarker of stress. The current pilot study examined changes in levels of cortisol in hair within the context of two time-intensity matched behavioral smoking cessation treatments: mindfulness training for smokers and a cognitive-behavioral comparison group. PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation. OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after …

Changes In Spirituality Partly Explain Health-Related Quality Of Life Outcomes After Mindfulness-Based Stress Reduction., Jeffrey M Greeson, Daniel M Webber, Moria J Smoski, Jeffrey G Brantley, Andrew G Ekblad, Edward C Suarez, Ruth Quillian Wolever

Jeffrey M. Greeson

Mindfulness-Based Stress Reduction is a secular behavioral medicine program that has roots in meditative spiritual practices. Thus, spirituality may partly explain Mindfulness-Based Stress Reduction outcomes. Participants (N = 279; M (SD) age = 45(12); 75% women) completed an online survey before and after an 8-week Mindfulness-Based Stress Reduction program. Structural equation modeling was used to test the hypothesis that, following Mindfulness-Based Stress Reduction, the relationship between enhanced mindfulness and improved health-related quality of life is mediated by increased daily spiritual experiences. Changes in both spirituality and mindfulness were significantly related to improvement in mental health. Although the initial mediation hypothesis …

Developing Mindfulness In College Students Through Movement Based Courses: Effects On Self-Regulatory Self-Efficacy, Mood, Stress, And Sleep Quality, Karen Caldwell, Mandy Harrison, Marianne Adams, Rebecca H. Quin, Jeffrey M. Greeson

Jeffrey M. Greeson

Objective—This study examined whether mindfulness increased through participation in movement based courses and whether changes in self-regulatory self-efficacy, mood, and perceived stress mediated the relationship between increased mindfulness and better sleep. Participants—166 college students enrolled in the 2007-2008 academic year in 15 week classes in Pilates, Taiji quan, or GYROKINESIS®. Methods—At beginning, middle, and end of the semester, participants completed measures of mindfulness, self-regulatory self-efficacy, mood, perceived stress and sleep quality. Results—Total mindfulness scores and mindfulness subscales increased overall. Greater changes in mindfulness were directly related to better sleep quality at the end of the semester after adjusting for sleep …

A Randomized Controlled Trial Of Koru: A Mindfulness Program For College Students And Other Emerging Adults., Jeffrey M Greeson, Michael K Juberg, Margaret Maytan, Kiera James, Holly Rogers

Jeffrey M. Greeson

OBJECTIVE: To evaluate the effectiveness of Koru, a mindfulness training program for college students and other emerging adults. PARTICIPANTS: Ninety students (66% female, 62% white, 71% graduate students) participated between Fall 2012 and Spring 2013. METHODS: Randomized controlled trial. It was hypothesized that Koru, compared with a wait-list control group, would reduce perceived stress and sleep problems, and increase mindfulness, self-compassion, and gratitude. RESULTS: As hypothesized, results showed significant Group (Koru, Wait-List)×Time (Pre, Post) interactions for improvements in perceived stress (F[1, 76.40]=4.50, p=.037, d=.45), sleep problems (F [1, 79.49]=4.71, p=.033, d=.52), mindfulness (F [1, 79.09]=26.80, p CONCLUSIONS: Results support the …

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 …

Psychosocial Functioning And The Cortisol Awakening Response: Meta-Analysis, P-Curve Analysis, And Evaluation Of The Evidential Value In Existing Studies, Ian Andres Boggero, Camelia E. Hostinar, Eric A. Haak, Michael L. M. Murphy, Suzanne C. Segerstrom

Psychology Faculty Publications

Cortisol levels rise immediately after awakening and peak approximately 30-45 minutes thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and metaanalysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw …

Coping With The Subterranean Environment: A Thematic Content Analysis Of The Narratives Of Cave Explorers, Raymond R. Macneil, Jelena Brcic

Journal of Human Performance in Extreme Environments

In addition to various physical obstacles, the cave environment presents numerous psychological stressors that challenge human explorers. Sources of psychological stress include logistic issues (e.g., limitations to access, communication, and the availability of equipment), a lack of normal sensory stimuli, isolation and confinement, high performance demands, and social conflict associated with team coordination and requirements for cooperation. Thus, the success and safety of caving expeditions depend on the ability of explorers to effectively cope with highly stressful conditions and task demands. This was the first study to investigate coping within the context of caving and cave exploration. Utilizing scoring criteria …

Adaptations to stress can occur through epigenetic processes and may be a conduit for informing offspring of environmental challenge. We employed ChIP-sequencing for H3K4me3 to examine effects of early maternal deprivation (peer-rearing, PR) in archived rhesus macaque hippocampal samples (male, n = 13). Focusing on genes with roles in stress response and behavior, we assessed the effects of rearing on H3K4me3 binding by ANOVA. We found decreased H3K4me3 binding at genes critical to behavioral stress response, the most robust being the oxytocin receptor gene OXTR, for which we observed a corresponding decrease in RNA expression. Based on this finding, we …

Parenting Children With Down Syndrome: An Analysis Of Parenting Styles, Parenting Dimensions, And Parental Stress, B. Allyson Phillips

Articles

Effective parenting is vital for a child’s development. Although much work has been conducted on parenting typically developing children, little work has examined parenting children with Down syndrome.

The purpose of the current study was to compare the parenting styles and dimensions in mothers of children with DS and mothers of TD children.

Thirty-five mothers of children with DS and 47 mothers of TD children completed questionnaires about parenting, parental stress, child behavior problems, and child executive function.

We found that mothers of children with DS use an authoritative parenting style less and a permissive parenting style more than mothers …

A Parent Education Curriculum For Decreasing Stress In Families Raising A Child With An Autism Spectrum Disorder, Hannah L. Wohlk

Electronic Theses, Projects, and Dissertations

Research has consistently shown that parents raising a child with autism spectrum disorders, or ASDs, have higher levels of stress than parents of typically-developing children or children with other disabilities. These parents’ higher levels of stress are attributed to a number of different factors, including early atypical development, getting the diagnosis, lack of awareness of resources, lack of support from their communities, unmet resource and schooling needs for their ASD child, financial strain, strain on the couple relationship, managing maladaptive behaviors, regulatory problems of the ASD child may experience, communication problems between ASD child and parent, parents’ perception of their …

Understanding Workplace Incivility Experiences And The Moderating Role Of Mindfulness, Rima C. Tarraf

Electronic Thesis and Dissertation Repository

Rude treatment at work can lead to many negative consequences, as evidenced by the wealth of research available. This dissertation, addressed two important questions that have yet to receive adequate attention. First, how does an employee experience incivility, and second, what is a practical and cost-effective way of mitigating the negative outcomes associated with incivility and promoting positive ones? Incivility research has mainly employed quantitative methods to understand incivility experiences. Using qualitative methods however, would complement the knowledge and potentially move the field of inquiry in new directions. As such, the goal of Study One was to obtain a narrative …

The Moderating Effects Of Positive Religious/Spiritual Coping On Teachers’ Pain And Stress, Dawn Green

Electronic Theses and Dissertations

The objective of this internet-based survey was to investigate the effects of positive religious or spiritual coping strategies on teachers’ chronic pain reports. Teachers in the United States may represent a vulnerable group due to a high prevalence of risk factors for chronic pain conditions. Teachers have been identified to experience high stress (Johnson, et al., 2005; Kyriacou, 2001) and report poor job satisfaction (Wang, Hall, & Rahimi, 2015), which are associated with development of chronic pain conditions (Kopec & Sayre, 2004). Religious coping strategies have been associated with beneficial associations with stress and health (Reutter & Bigatti, 2014). The …

The Imagine Project: Inspiring Vulnerable Adults Through Art And Mindfulness, Janelle Defiesta

Master's Projects and Capstones

The IMAGINE Project tackles the issue of stress reduction for a population that faces high stress levels due to environmental instability with co-morbidities of prior physical, cognitive, and social issues. Despite the need of stress reduction approaches in a population under these circumstances, external factors make it difficult to reduce the problem. Consequently, the lack of stress reduction skills can lead to the exacerbation of existing problems and the onset of many others. However, until basic needs such as housing and sustenance are met, stress reduction cannot be attempted effectively. Thus, the target population for this project focused on people …

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. …

Impact Of Stress, Fear And Anxiety On The Nociceptive Responses Of Larval Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Lynne U. Sneddon

Sentience Collection

Both adult and larval zebrafish have been demonstrated to show behavioural responses to noxious stimulation but also to potentially stress- and fear or anxiety- eliciting situations. The pain or nociceptive response can be altered and modulated by these situations in adult fish through a mechanism called stress-induced analgesia. However, this phenomenon has not been described in larval fish yet. Therefore, this study explores the behavioural changes in larval zebrafish after noxious stimulation and exposure to challenges that can trigger a stress, fear or anxiety reaction. Five-day post fertilization zebrafish were exposed to either a stressor (air emersion), a predatory fear …

Regulating Anger Under Stress Via Cognitive Reappraisal And Sadness, Jun Zhan, Xiaofei Wu, Jin Fan, Jiayou Guo, Jianshe Zhou, Jun Ren, Chang Liu, Jing Luo

Publications and Research

Previous studies have reported the failure of cognitive emotion regulation (CER), especially in regulating unpleasant emotions under stress. The underlying reason for this failure was the application of CER depends heavily on the executive function of the prefrontal cortex (PFC), but this function can be impaired by stress-related neuroendocrine hormones. This observation highlights the necessity of developing selfregulatory strategies that require less top-down cognitive control. Based on traditional Chinese philosophy and medicine, which examine how different types of emotions promote or counteract one another, we have developed a novel emotion regulation strategy whereby one emotion is used to alter another. …

Development And Validation Of The Distress Tolerance Questionnaire (Dtq), Elizabeth C. Rojas

USF Tampa Graduate Theses and Dissertations

Distress tolerance (DT) is the perceived ability to withstand psychological stress, and has been studied for its relationship to psychopathology, personality features, mood states, and behaviors. Previous work suggests that the two existing modalities of DT measurement (behavioral and self-report) are tapping conceptually and empirically different constructs. The current developed a novel, self-report measure of DT that conceptually mapped onto behavioral DT in two samples: community participants (N = 982) and undergraduates (N = 282). Two separate factors emerged, non-goal oriented distress intolerance (DI), and goal-oriented distress tolerance (DT). Fit indices were acceptable in the community sample, but poor in …

Stress And Psychotherapy Outcome: Implementation Of A Heart Rate Variability Biofeedback Intervention To Improve Psychotherapy Outcome, Louise Fidalgo Wheeler

Theses and Dissertations

Research has shown that psychotherapy patients experience increased physiological responsivity to stress which might negatively impact their experience in psychotherapy and their overall progress and outcome. The purpose of the present study was to investigate the effect of a heart rate variability biofeedback intervention on the physiological stress responsiveness and the psychotherapy outcomes of participants in psychotherapy. Forty college students attending psychotherapy at their university counseling center were divided into an experimental group and a control group. The experimental group participated in a 6-week biofeedback intervention and we assessed their physiological stress reactivity before and after implementation of the intervention, …

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 Effect Of Therapy Dogs On Children In A Learning Environment, Kimberly Ann Sheckler

Theses and Dissertations

Having a dog in school can seem exciting for many students, but can these furry companions actually help students attain higher levels of academic success? The benefits of therapy dogs in an educational setting can be seen in many research studies. Dogs in the classroom can be used to calm fears, relieve anxiety, and teach skills to students (Lessons Learned from Dogs in the Classroom, 1996). Even though there is much evidence of the positive benefits of therapy dogs in a school, many schools still choose not to have therapy dog programs. This thesis looks at the benefits of therapy …

Beyond Access Towards Success For First-Generation College Students Of Underrepresented Ethnic Backgrounds: The Role Of College Adjustment And Perceived Stressors On Academic Achievement During The First Year, Shannon Williams

College of Science and Health Theses and Dissertations

The current study explored the first year college transition between traditional and underrepresented student groups (ethnic minorities and first-generation college students; N = 500; M age = 18.34) at a diverse institution, comparing GPA and college adjustment over time. Using Tinto’s retention model (1975), the aim of the current study explored whether social and academic adjustment differences would explain any gap in academic achievement among underrepresented students groups. Results indicated that first-generation college students (FGC) of minority ethnic backgrounds reported significantly lower GPA scores, and had lower adjustment subscale scores compared to all other student groups by the end of …

The Relationship Between Mindfulness And Stress Among College Students, Elizabeth Marie Vonderheyde

Theses and Dissertations

College students who have high levels of stress have reported difficulties with functioning on a daily basis, whether it be high anxiety due to classes or an increase in unhealthy habits like smoking or overeating. Studies have shown that those who practice mindfulness every day learn how to live with accepting the stresses in their lives (Siegel & Allison, 2016). This study explored the relationship between mindfulness and stress in college students from a medium size public university in the northeast. Two self-report measures were used to collect data though an online survey. Data were subjected to descriptive and inferential …

Stress Exposure Training As A Means For Athletes To Prevent Paradoxical Performance, Adam M. Fulton

Student Works

Paradoxical performance has been studied for years, with an emphasis on helping athletes prevent choking under pressure. However, although progress has been made, too many athletes are still underperforming due to anticipated and unanticipated stressors (Baumeister & Showers, 1986, p. 362). Stress exposure training is suggested as a solution to choking under pressure, even though little research has been done. A review of the literature on paradoxical performance is presented, emphasizing skills that appear to be effective and could be inserted into a stress exposure training program. Skills such as self-consciousness training, positive self-talk, self-confidence, pre-performance routines, and others could …

Preadolescent Sensation Seeking And Early Adolescent Stress Relate To At-Risk Adolescents' Substance Use By Age 15, Nora E. Charles, Charles W. Mathias, Ashley Acheson, Donald M. Dougherty

Faculty Publications

Background and aims

Substance use during adolescence can lead to the development of substance use disorders and other psychosocial problems. These negative outcomes are especially likely for individuals who use substances at earlier ages and those who engage in heavier use during adolescence, behaviors which are both more common among youth at higher risk for developing a substance use disorder, such as those with a family history of substance use disorders (FH +). Factors such as increased sensation seeking and greater exposure to stressors among FH + youth may influence these associations. Therefore, the aim of this study was to …

Does Social Support Diminish Depression In Students? Evidence From Athletes And Greek Life, Benjamin Chartoff, Myra Beth Bundy

Kentucky Journal of Undergraduate Scholarship

Depression and stress are extremely prevalent in college students. The goal of the current study was to examine if social support from athletic teams and fraternities or sororities are related to lower levels of depression and stress than that found in students normally. Participants (N=134) were asked to fill out a questionnaire with scales of depression, stress and social support. It was hypothesized that members of Greek life and student-athletes will show higher levels of social support and lower levels of depression compared to a control group of students. The results supported these hypotheses and suggest that joining social groups …

Reward Preferences In Domestic Horses (Equus Caballus), Elizabeth E. Jaeger

Theses and Dissertations

The present study examined stress response in domestic horses (Equus caballus) to determine if horses show preference for either traditional or natural horsemanship training methods to test the hypothesis that natural horsemanship would induce less stress. Our results show that natural horsemanship rewards elicited lower stress response in horses.
