Individual Differences In Cannabis Use Disorder With Implications For Endocannabinoid Modulation In Therapeutics Development, Erin Martin

MUSC Theses and Dissertations

Cannabis use disorder (CUD) is increasingly prevalent in the United States, but there is no effective pharmacological means to treat it. The endocannabinoid (eCB) system has emerged as a candidate therapeutic target demonstrating some evidence of efficacy in treating CUD. However, clinical trials evaluating eCB-modulating therapeutics have historically undervalued individual differences that could contribute to variation in treatment outcome (e.g. sex, comorbid psychiatric illness). To address this gap in the literature, the present set of studies (a) compared plasma eCB tone in groups underrepresented in treatment trials for CUD (females, individuals with comorbid major depressive disorder; MDD/CUD) with males or …

Prevalence Of Depression, Anxiety And Stress After The Covid-19 Pandemic Period Among Students At The Medical University Of Sofia; Significance Of Demographic, Educational, And Pandemic-Related Variables, Nadya Avramova

Journal of Mind and Medical Sciences

This cross-sectional study aimed to determine the prevalence of depression, anxiety, and stress among undergraduate dental students at Sofia Medical University and to investigate its associations with some demographic, educational and pandemic-related variables. A self-reported questionnaire that included the validated DASS-21 scale was administered to a group of 2nd, 3rd, 4th, and 5th year students (n=70, response rate 95.7%). Results indicated abnormal levels of depression, anxiety, and stress in 34.3%, 65.7% and 59.7% of the participants, respectively. A much larger proportion of females suffered from abnormal levels of anxiety (56.6%) as compared with males (9%), p=.003. Single students exhibited significantly …

Exploring The Effects Of Christian Worldviews On Heart Rate, Stress, And Adjustment After Loss In Bereaved Individuals, Emma Radini Ratnavel

Honors Scholar Theses

The objective of this study is to investigate the correlation between Christian values, perceptions of God, and physiological stress, assessed through heart rate, among individuals who are experiencing grief due to the loss of a loved one. Previous studies have analyzed various physiological effects on the body. There are very few studies that examine the correlation between Christian values and heart rate in bereaved participants. To explore these topics further, this study analyzes 59 undergraduate students who have recently lost a loved one, identify as a Christian, and are at least 18 years old. The participants' perceptions of God and …

Role Of Chronic Stress-Induced Neuroinflammation In Rodent Locus Coeruleus Physiology And Anxiety-Like Behaviors, Arthur Anthony Alfonso Reyes

Graduate School of Biomedical Sciences Theses and Dissertations

The locus coeruleus (LC), the primary site of brain norepinephrine (NE), is a key anatomical brain region implicated in the stress response. Stress is a neuroendocrine physiologic response to a stressor that promotes organism survival through adaptive change and restoration of homeostasis. The central stress response, which drives behavioral and physiological change, is primarily mediated by activating the hypothalamic-pituitary-adrenal (HPA) axis. While advantageous in the short term, chronic stress exposure can lead to HPA axis and LC dysregulation, which are thought to contribute to the etiology of anxiety disorders. Previous studies demonstrate the effects of acute stress in increasing LC …

The Benefits Of Art Therapy On Stress And Anxiety Of Oncology Patients During Treatment, Helen Shiepe

Expressive Therapies Capstone Theses

Within the last ten years research on art therapy and its positive impact on oncology patients’ stress and anxiety during treatment has been minimal. Oncology patients whether they are children or adults when diagnosed experience similar reactions due to their diagnosis, treatment, and in some cases end of life care. The current question is whether or not art therapy does have a positive impact on decreasing the stress and anxiety with oncology patients while undergoing treatment. Deane, Fitch & Carmen (2000), discussed art therapy as a healing art that is “intended to integrate physical, emotional, and spiritual care by facilitating …

Master's Projects and Capstones

Problem: The use of evidence-based alternative forms of therapy like horticulture therapy and therapeutic gardening is underutilized in substance use recovery programs in the United States. As the country continues to struggle with addiction, it is important that recovery programs look to and incorporate these alternative therapies into official curricula. Currently, 46.3 million individuals living in the United States are living with a substance use disorder (U.S Department of Health and Human Services’ Substance Abuse and Mental Health Services Administration, 2022).

Context: The intervention was implemented at an all-male substance use treatment facility in San Jose, CA that houses up …

The Influence Of Nutrition On The Gut Microbiota And Psychiatric Disorders: A Review, Megha Bhagavan, Francis Jenney

Research Day

The symbiotic harboring of gut microorganisms within the gastrointestinal tract has a profound influence on host physiology, well-being, and disease pathology. More specifically, the gut bacteria are able to interact with dietary components from foods chosen by the host and consequently relay their beneficial or precarious effects locally and systemically. The gut bacteria have the capacity to maintain a healthy gut microbiome or perpetuate intestinal imbalance, known as gut dysbiosis. Gut dysbiosis has both local effects in gastrointestinal pathologies, such as intestinal bowel syndrome (IBS) and intestinal bowel disorder (IBD), as well as systemic pathologies, such as type II diabetes, …

Examining The Effects Of A Zoom Interview On Cortisol, Bennett Perkins

Psychological Science Undergraduate Honors Theses

The stress response is an essential physiological process that facilitates survival in threatening conditions. Stress impacts numerous bodily systems, and prior work has focused on cortisol, a steroid derived from cholesterol, as a key biomarker for assessing biological stress reactivity in humans. Social stressors are known to contribute to marked increased in cortisol levels, but to date little work has examined whether social situations known to be stressful in person can influence cortisol when those situations occur remotely. In this study, I investigated the effects of a Zoom-based social stressor on salivary cortisol. Participants were randomly assigned to the Zoom-stress …

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 …

Conditioned Place Avoidance Is Associated With A Distinct Hippocampal Phenotype, Partly Preserved Pattern Separation, And Reduced Reactive Oxygen Species Production After Stress, D. Parker Kelley, Lucas Albrechet-Souza, Shealan Cruise, Rajani Maiya, Aspasia Destouni, Siva S.V.P. Sakamuri, Alexander Duplooy, Meghan Hibicke, Charles Nichols, Prasad V.G. Katakam, Nicholas W. Gilpin, Joseph Francis

School of Medicine Faculty Publications

Stress is associated with contextual memory deficits, which may mediate avoidance of trauma-associated contexts in posttraumatic stress disorder. These deficits may emerge from impaired pattern separation, the independent representation of similar experiences by the dentate gyrus-Cornu Ammonis 3 (DG-CA3) circuit of the dorsal hippocampus, which allows for appropriate behavioral responses to specific environmental stimuli. Neurogenesis in the DG is controlled by mitochondrial reactive oxygen species (ROS) production, and may contribute to pattern separation. In Experiment 1, we performed RNA sequencing of the dorsal hippocampus 16 days after stress in rats that either develop conditioned place avoidance to a predator urine-associated …

Promoting Well-Being Among Intercollegiate Student-Athletes: A Gratitude Intervention Using Positive Psychology, Laura Kruger

Dissertations and Theses

Intercollegiate student-athletes face rising stress and pressures which challenge their well-being and mental health, and sometimes with alarming concerns. Over the years, supportive services and resources specifically available to student-athletes have not evolved at the same pace as student-athlete needs. Also, barriers and stigmas hinder student-athletes from readily accessing supportive mental health services. The high stress of student-athletes can contribute to the development of negative mental health symptoms and impairs positive well-being. Evidence supports how outreach initiatives help student-athletes. Positive psychology, including gratitude as a positive psychological state, has shown benefits to well-being. This experimental study design researched if the …

Neurobiology Of Ptsd In Adults And Children: The Impact Of Stress-Induced Brain Abnormalities Across The Lifespan, Catherine Clover

Undergraduate Honors Theses

In the scholarly community, there is disagreement about the effects of PTSD or chronic stress on the brain of adults and children. Though PTSD or chronic stress are known to negatively affect neurobiological structures, specifically due to prolonged glucocorticoid excess, volumetric discrepancies between traumatized and control groups are not unanimously confirmed. This review sought to address the common understandings in academia of the effects of PTSD on the brains of adults and children. Literature on this topic indicated that, in adults, the hippocampus, cingulate gyrus, and prefrontal cortex bilaterally appeared to decrease in gray matter volume and the corpus callosum …

Interpersonal Psychotherapy’S Problem Areas As An Organizing Framework To Understand Depression And Sexual And Reproductive Health Needs Of Kenyan Pregnant And Parenting Adolescents: A Qualitative Study, Manasi Kumar, Obadia Yator, Vincent Nyongesa, Martha Kagoya, Shillah Mwaniga, Joseph Kathono, Isaiah Gitonga, Nancy Grote, Helena Verdeli, Keng Yen Huang

Brain and Mind Institute

Background: Peripartum adolescents experience signifcant interpersonal transitions in their lives. Depression and emotional distress are often exacerbated by adolescents’ responses to these interpersonal changes. Improved understanding of pregnancy-related social changes and maladaptive responses to these shifts may inform novel approaches to addressing the mental health needs of adolescents during the perinatal period. The paper aims to understand the sources of psychological distress in peripartum adolescents and map these to Interpersonal Psychotherapy’s (IPT) problem areas as a framework to understand depression.

Method: We conducted interviews in two Nairobi primary care clinics with peripartum adolescents ages 16–18 years (n=23) with …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

Stressed Out And Stressed In: Regulating The Stress Response At An Endocrine Level Through Dance/Movement Therapy, Alicia Randazzo

Dance/Movement Therapy Theses

This thesis proposes dance/movement therapy as an approach to regulating the stress response from the perspective of the endocrine system. By examining the endocrine system’s role specifically in the human stress response, one can gain clearer understanding of the hormonal components involved in the process of perceiving a stressor, reacting to it, and returning to homeostasis, as well as what happens when that process is interrupted, overworked, or dysfunctional. The impacts of these internal processes can manifest physically, mentally, emotionally, socially, and cognitively – making dance/movement therapy well-suited to thoroughly address them. This assertion was made following the investigation of …

Increased Risk Of Mental Illness Due To Epigenetic Alteration Of The Nr3c1 Gene After Early Life Adversity., Erin Mccue

Thinking Matters Symposium

Early life adversity (ELA), such as malnutrition, abuse, and economic disparity, is an issue commonly seen in adolescents, a group already facing increased risk for stress-related disorders. This review of current literature reveals that gestational stress exposure, as well as variations in maternal care during postnatal development, cause latent effects on the epigenome, specifically impacting the glucocorticoid receptors (GRs) encoded by the NR3C1 gene. GRs bind to glucocorticoids to regulate the body’s neuroendocrine stress response. However, in those with a history of ELA, the number of GRs is reduced, generating dysregulation within the hypothalamic-pituitary-adrenal (HPA) axis. Rodent studies are utilized …

“This Isn’T Just Busy, This Is Scary”: Stress, Social Support, And Coping Experiences Of Frontline Nurses During The Covid-19 Pandemic, Erin S. Craw, Tess M. Buckley, Michelle Miller-Day

Communication Faculty Articles and Research

During the pandemic, nurses struggle to care for patients and protect themselves from infection, while navigating ongoing organizational changes. Guided by prior literature on social support and coping, this study explores nurses’ experiences of coping with stress while treating COVID-19 patients during the pandemic. In-depth semi-structured interviews were conducted with 14 active staff nurses working in hospitals and one licensed practical nurse (LPN) at a rehabilitation center who treated COVID-19 patients during the pandemic. An inductive thematic analysis was employed …

Sex Differences In Cognitive Flexibility Are Driven By The Estrous Cycle And Stress-Dependent, Andrew T. Gargiulo, Jiayin Hu, Isabella C. Ravaglia, Annie Hawks, Xinyue Li, Katherine Sweasy, Laura A. Grafe

Psychology Faculty Research and Scholarship

Stress is associated with psychiatric disorders such as post-traumatic stress disorder, major depressive disorder, anxiety disorders, and panic disorders. Women are more likely to be diagnosed with these stress-related psychiatric disorders than men. A key phenotype in stress-related psychiatric disorders is impairment in cognitive flexibility, which is the ability to develop new strategies to respond to different patterns in the environment. Because gonadal hormones can contribute to sex differences in response to stress, it is important to consider where females are in their cycle when exposed to stress and cognitive flexibility testing. Moreover, identifying neural correlates involved in cognitive flexibility …

Science University Research Symposium (SURS)

Cognitive Load Effect on Moral Decision Making

Elise Crause, Merry Bailey, Liz Eisenga, Caroline Hopper

Choices are made each day to determine the outcome of our lives. To better understand the human process of decision making, philosophers and psychologists have examined moral dilemmas. Cognitive load is a type of stress that alters decision-making and the likelihood of choosing a self-motivated behavior over a behavior that benefits another person or group. For this study, moral dilemmas were given in sets of two before and after a cognitive-load-inducing task. The cognitive-load-inducing task required participants to verbally answer subtraction problems until the answer …

Family Structure And Maternal Depressive Symptoms: A Cross-National Comparison Of Australia, The United Kingdom, And The United States, Kirsten Rasmussen, Elizabeth K. Sigler, Sadie A. Slighting, Jonathan A. Jarvis, Mikaela J. Dufur, Shana Pribesh

Educational Foundations & Leadership Faculty Publications

The purpose of this study is to understand the relationship between family structure and maternal depressive symptoms (MDS) in Australia, the United Kingdom, and the United States. Family structures that involve transitions across life's course, such as divorce, can alter access to resources and introduce new stressors into family systems. Using the stress process model, we examine the links between family structure, stress, resources, and MDS. Using nationally representative data from Australia, the United Kingdom, and the United States and cross-sectional models for each country, we find that family structure may influence MDS differently in the UK than it does …

Impact Of The Covid-19 Pandemic On Child Anxiety Symptoms: The Influence Of The Caregiver-Child Relationship, Rebecca Hoppe

Theses and Dissertations

Research suggests that youth are dealing with a myriad of worries during the COVID-19 pandemic (Ellis et al., 2020), which highlights the need for investigations focused on child anxiety. However, to date little research has examined children’s anxiety in the COVID-19 pandemic nor the potential protective effects of the caregiver-child relationship. Therefore, this research aimed to contribute to the literature by investigating the influence of COVID-19 related stressors in younger children and leveraging children’s report of their own attachment security within their relationship with their caregiver and mental health. The current study used a national, quantitative survey of young children …
