Modeling Blue Mondays: A Preclinical Evaluation Of 3,4-Methylenedioxymethamphetamine Binge Dosing On Responding Maintained By A Progressive Ratio Schedule Of Food Reinforcement In Male Sprague-Dawley Rats, Candace Brenda Johnson

Dissertations

3,4-Methylenedioxymethamphetamine (MDMA) has been abused recreationally in the rave scene for decades. As pharmacotherapy research has progressed to develop alternative medications to treat trauma-related psychiatric symptoms, MDMA has become a prime candidate for medication-assisted psychotherapy in the treatment of PTSD and will soon be FDA approved for medicinal use. Despite convincing evidence for favorable clinical outcomes, this substance has been known to contribute to acute depressive states following excessive use. The sharp decrease in mood and cognitive impairment following MDMA use is colloquially termed Blue Mondays. Measuring lack of motivation or more broadly anhedonia through withdrawal of acute and chronic …

Using Self-Assessment Tools And Complementary Alternative Therapy For Chronic Migraines In Menopausal Women, Krystal Rachelle Bridwell

Electronic Theses and Dissertations

Abstract

Migraine headaches are ranked as one of the highest disabling conditions in the United States. Women who are in the perimenopausal transition phase have a higher prevalence of disabling migraines that can result in a decreased quality of life, loss of income, decreased productivity, and a higher risk for emotional difficulties. The gap in practice is the lack of education on complementary alternative medicine (CAM) and the use of a migraine diary to recognize individual symptoms as a substitute or cotherapy with pharmacologic treatments. The purpose of this scholarly project was to improve clinical practice and outcomes for perimenopausal …

Death With Dignity: Queer Representation In Deathcare Systems, Esmé Ringelstetter

University Honors Theses

This thesis examines the ways that elderly members of the LGBT community lack representation within deathcare systems. Currently, the LGBT community is vastly underrepresented in research relating to the dying process and deathcare. This lack of representation creates barriers for LGBT individuals at the end of their lives and creates difficult end-of-life experiences. I utilized previous research that studied how LGBT populations interact with and are treated by a variety of death care-related systems, including health systems, legal systems, and therapeutic systems. This research highlighted the need for the LGBT community to be better represented within both research relating to …

At The Intersection Of Domestic Violence And Mass Shootings: A Qualitative Analysis Of The Relationship Between Ipv And Gun Violence, Troy Bleau

University Honors Theses

The intersectional study of domestic violence and mass shootings has only recently been the subject of inquiry within the psychology field. Within the past ten years research has been developed to examine the relationship between these two epidemics. What authors have found is that DV does play a role in shooting perpetration. This study aimed to identify domestic violence as a risk factor to predict, and subsequently intervene before future instances of shootings. 112 shootings were analyzed between the years of 2020 and 2023--they were then categorized as DV-related, non-DV related, and/or History of DV. The tested hypothesis was that …

Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response, Jacinth Jia Xin Tan, Chin Hong Tan, Michael W. Kraus

Research Collection School of Social Sciences

Higher resting heart rate variability (HRV)—an index of more flexible response to environmental stressors, including noxious stimuli—has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one’s chronic environments, we propose that chronic exposure to threats captured by one’s subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, …

Depressive Symptoms And Substance Use Behaviors Among Young Adults Before And During Covid-19, Sarah Chun

Clinical Psychology Dissertations

Exposure to previous public health disasters have been found to have a significant negative impact on young adult mental health. Thus, it is important to examine the effect that COVID-19 had on young adult mental health. The current study examined differences in depressive symptoms as well as frequency and impairment of substance use in two cross-sectional samples of undergraduate students, one before COVID-19 and one during COVID-19. This study also examined the moderating effects of religiosity on the association between COVID-19 status and both depressive symptoms and substance use behaviors. Participants were 898 young adults (M_age = 19.83, …

Individual Longitudinal Changes In Dna-Methylome Identify Signatures Of Early-Life Adversity And Correlate With Later Outcome, Annabel K. Short, Ryan Weber, Noriko Kamei, Christina Wilcox Thai, Hina Arora, Ali Mortazavi, Hal S. Stern, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Adverse early-life experiences (ELA) affect a majority of the world's children. Whereas the enduring impact of ELA on cognitive and emotional health is established, there are no tools to predict vulnerability to ELA consequences in an individual child. Epigenetic markers including peripheral-cell DNA-methylation profiles may encode ELA and provide predictive outcome markers, yet the interindividual variance of the human genome and rapid changes in DNA methylation in childhood pose significant challenges. Hoping to mitigate these challenges we examined the relation of several ELA dimensions to DNA methylation changes and outcome using a within-subject longitudinal design and a high methylation-change threshold. …

How African American Clergy Perceive The Cultural Relevance And Usefulness Of The Mental Health Guide For Faith Leaders, Lisa Marie Harris

Walden Dissertations and Doctoral Studies

African Americans experience mental illness at a rate similar to White individuals but are less likely to seek professional mental health care. African Americans have traditionally turned to the Black church for mental health assistance. Various organizations have created mental health resources for clergy members, with varying levels of comprehensiveness. The purpose of this basic qualitative study was to explore how African American clergy perceived the cultural relevance and usefulness of the American Psychiatric Association Foundation’s Mental Health Guide for Faith Leaders. The study was conducted using critical race theory as its theoretical framework. Four experienced clergy participated in two …

Stress And Coping Experienced By Mothers With Autoimmune Diseases While Parenting Children With Autism, Christine Marie Dillon

Walden Dissertations and Doctoral Studies

The number of individuals diagnosed with autoimmune diseases (AD) continues to rise, with the majority being women of childbearing age. There has been a concurrent increase in the number of children diagnosed with autism spectrum disorder (ASD). Mothers of children with ASD are often the primary caretaker for their children, and report decreased quality of life and increased behavioral health concerns. AD and ASD have been studied separately through a quantitative lens, with findings demonstrating similarities between the two regarding potential etiology. Few qualitative studies have been conducted to understand the stress and coping experienced by mothers with AD parenting …

The Lived Experience Of Parents With Newborns In The Neonatal Intensive Care Unit (Nicu): A Heuristic Inquiry, Abigail Bilyk

Walden Dissertations and Doctoral Studies

Parents with newborns who require medical care in the Neonatal Intensive Care Unit (NICU) immediately following birth are at an increased risk of experiencing psychological distress. While quantitative research studies have determined that a NICU admission can have detrimental effects on parents, a better understanding of the lived experience for both mothers and fathers is necessary to ensure adequacy in the standard of care given to parents while their newborn is admitted to the NICU. The phenomenon has not previously been explored using the phenomenological approach of heuristic inquiry. Constructivism, social constructivism, and the transactional model of stress and coping …

Impact Of Workplace Racial Discrimination On The Health Of Black Men, Denise Richardson

Walden Dissertations and Doctoral Studies

The purpose of this qualitative phenomenological study was to explore the lived racially discriminatory experiences of Black men in the workplace in New York City and how those incidents affected their overall health. The study used Critical Race Theory as the theoretical framework and analyzed data gathered through semi-structured interviews with 10 participants. Findings from coding analysis indicated that Black men routinely engaged in acts of John Henryism to receive positive recognition as they navigated negative societal stereotyping, namely proving that they, as individuals, were not negative stereotypes. Additionally, the study revealed that exposure to racial discrimination in the workplace …

Consciousness And The Reality Of Monsters In Horror Movies: Dehumanization And What Monsters In Horror Films Say About Us, Leila Kincaid

Journal of Conscious Evolution

This essay responds to Carroll’s The Nature of Horror from the perspective of transdisciplinary phenomenological film theory, largely developed by Edgar Morin in the 1950s. It argues that Carrolls’s reduction of the phenomenological value of horror films to an unreal category minimizes and even dismisses the inherent value of horror films. Morin, Allan Combs, and others offer more integral and transdisciplinary methods for art interpretation and functionality. They help us understand how monsters in horror films can stand as mirrors and reflections of the monstrous in ourselves and society. Thus, the transformational function and value of film is revealed and …

Gender Diversity In The Workplace: Pronouns, Gender-Stereotyped Job Listings, And Perceptions Of Hireability, Elise B. Charette, Sarah E. Nemanick, Paige C. Keim, Sarah M. Ledoux, Lindsay A. Goolsby, E. Paige Lloyd

DU Undergraduate Research Journal Archive

Past research has investigated the impact of gender and gender biases on hiring decisions for cisgender individuals. However, there is a lack of research on how perceptions of gender diverse individuals impact hiring decisions. The current work explores how a job applicant’s gender pronouns may impact the likelihood of the applicant getting hired. We also investigated whether this likelihood varied depending on the job description—specifically whether it included content related to gender stereotypes (e.g., “nurturing” versus “leadership capabilities” as a desired trait in job applicants). Ninety-six participants were randomly assigned to view an application package including she/her, he/him, or they/them …

Comparison Of Vivitrol And Suboxone In Terms Of Lowering Relapse Among Opioid Addicts, Nicolle Tourdot

Walden Dissertations and Doctoral Studies

Drug overdoses are increasing, and the heroin epidemic is becoming more evident. There are ways to get these individuals’ help. Medically assisted treatments (MATs) involve use of medications alongside counseling and therapies to treat individuals with a substance abuse disorder. This subject is important to the human services administration field, more specifically those who focus on addiction. As the epidemic of opioid use continues, so does the need for treatment. Without that treatment, the problem will get worse and inevitably have negatives effects on the entire world. Those effects involve crime, increasing costs to the public, overall health, and child …

It Takes A Village: Stories Of Black Grandparents Raising Grandchildren, Cherieda A. Washington

Walden Dissertations and Doctoral Studies

While several studies have reviewed the experiences of Black grandparent caregivers, there are limited sources that describe the stories of Black grandparents who are caregivers for their grandchildren and the challenges they face. Utilizing the concepts from Bowen family systems theory, the goal of this study was to explore the stories of Black grandparents who are caregivers for their grandchildren to discover preventive and enhanced counseling techniques for the next generation. Data were collected and analyzed from narrative inquiry interviews with six participants who were Black caregivers for their grandchildren in the state of Mississippi. After analysis of the data, …

The Self-Perceived Level Of Wellness Among Ghanaian Mental Health Counselors, Adwoa Bonney-Graves

Walden Dissertations and Doctoral Studies

In Ghana, many people seek help for their mental health; however, despite the great need, there are often barriers or factors that can create unwellness among mental health counselors. There is a gap in the research literature addressing whether unwellness among Ghanaian mental health counselors is caused by external factors of counselor caseload, low funding, and minimal work staff. This quantitative study aimed to fill this gap by using predictive regression analysis to determine whether there is a correlation between Ghanaian counselors’ unwellness and counselor caseload, low funding, and minimal work staff. The study participants (N = 96) were Ghanaian …

Prediction Of Disease-Free Survival For Precision Medicine Using Cooperative Learning On Multi-Omic Data, Georg Hahn, Dmitry Prokopenko, Julian Hecker, Sharon M Lutz, Kristina Mullin, Leinal Sejour, Winston Hide, Ioannis Vlachos, Stacia Desantis, Rudolph E Tanzi, Christoph Lange

Faculty, Staff and Student Publications

In precision medicine, both predicting the disease susceptibility of an individual and forecasting its disease-free survival are areas of key research. Besides the classical epidemiological predictor variables, data from multiple (omic) platforms are increasingly available. To integrate this wealth of information, we propose new methodology to combine both cooperative learning, a recent approach to leverage the predictive power of several datasets, and polygenic hazard score models. Polygenic hazard score models provide a practitioner with a more differentiated view of the predicted disease-free survival than the one given by merely a point estimate, for instance computed with a polygenic risk score. …

Exploring Black Business Owners' Experience In Public Procurement Contracts, Khamillia Harris

Doctoral Dissertations and Projects

Black businesses are on the rise in the United States, and most are formed with the goal of achieving greater economic stability and positive impact on their communities. However, Black business owners often lack sufficient opportunities and access to essential resources (i.e., capital), which negatively affects their business stability efforts (Bento & Hwang, 2022). Black business owners can access procurement contracts as a unique way to access capital to grow and sustain their businesses (Chepkoit, 2018; Shelton & Minniti, 2018), yet they received 1.67% of public funds compared to 15.64% awarded to other non-minority small businesses (Choi et al., 2022; …

The Impact Of Adverse Childhood Experience (Ace) On Victims' Self-Perception And Moral Character Development In Adulthood, Josephine Afua Owusu

Doctoral Dissertations and Projects

Adversity experienced in childhood is known to have debilitating consequences that permeate subsequent life experiences and predict adulthood wellbeing. The intensity and nature of this impact vary, however. Empirical and practical knowledge also point to the significant role of self-perception in determining one’s view of others, character development, and life experiences. Research has suggested associations between childhood adversities and self-perception, although this knowledge is scanty and inconsistent, with similarly minimal evidence on their correlation with character development. This study set out to examine how adverse childhood experiences (ACEs) influence victims’ self-perception and character development in adulthood. It employed a mixed …

Department of Psychology: Faculty Publications

The emerging field of Nutritional Cognitive Neuroscience aims to uncover specific foods and nutrients that promote healthy brain aging. Central to this effort is the discovery of nutrient profiles that can be targeted in nutritional interventions designed to promote brain health with respect to multimodal neuroimaging measures of brain structure, function, and metabolism. The present study therefore conducted one of the largest and most comprehensive nutrient biomarker studies examining multimodal neuroimaging measures of brain health within a sample of 100 older adults. To assess brain health, a comprehensive battery of well-established cognitive and brain imaging measures was administered, along with …

The Exploration Of Latino Bip Participants' Experiences Of Oppression And Expressions Of Critical Consciousness, Adrian Luis Manriquez

Dissertations and Theses

According to Freire (1970), individuals and groups who are systemically oppressed in society often develop and struggle with a sense of internalized oppression, and those who fail to address their own oppression will likely engage in the oppression of others. Conceivably, this is the state of affairs for Latino males who perpetrate intimate partner violence (IPV). However, Latinos who use IPV behaviors are often viewed solely as "villains" or oppressors (Corvo & Johnson, 2003), omitting the various contexts in which this subgroup of males might be subjected to oppressive conditions outside of their intimate relationships. This contributes to an absence …

Past Experiences And Current Attitudes: Is Everything Connected?, Miranda Oddy

Honors Projects

The purpose of this study was to explore the ways past experiences with mental health issues affect current stigma and outlook on life. I investigated whether a personal experience or the experience of someone close (e.g., family, friend) with mental health issues impacted stigma and outlook more than other. The sample included 242 participants who were 18 to 86 years old (M_age = 27.44, SD_age = 16.58), 51.7% white, and 77.3% female. Surveys were advertised on a small liberal arts university offering class credit for students and online. The survey included questions on life satisfaction, optimism, stigma, and …

The Archeology Of Adoption: Tracing The Journey From Birth Through Adoption Using Pre-Adoptive Artifacts, Ellen Reeve

Educational Studies Dissertations

Adults adopted in childhood often face a heightened susceptibility to psychological and behavioral challenges compared with their non-adopted peers. Scholars examining this phenomenon associate various factors, including an adoptee’s sense of self as an individual within a complex adoption background. This qualitative study utilized a material engagement theory to explore birth through adoptive narratives among adults adopted in closed settings during childhood. Through participatory research, participants examined a range of artifacts related to maternal relinquishment, encompassing foster and adoption records, original birth certificates, letters, photographs, birthmarks, clothing, hair, scars, and DNA test results. The study focused on understanding these artifacts’ …

Navigating Cultural Transitions: A Drama Therapy Exploration Of Culture Shock Among International Students From South Asia And East Asia, Rithika Gopalakrishnan

Expressive Therapies Capstone Theses

South Asia and East Asia drive the recent surge in US global student enrollment, exceeding one million, collectively representing 60.141% of international students, with China and India contributing 53% alone. These figures underscore the need for focused research into the experiences of South Asian and East Asian international students in the United States, an area currently lacking comprehensive study. This thesis examines culture shock among South Asian and East Asian students at a university in the Northeast, exploring relevant theories, role of media portrayals, and drama therapy interventions. It investigates the effects of culture shock, such as strain, loss, rejection, …

Grief Like Mine: A Literature Review Exploring Culturally Informed Grief Work For Black Youth Using Dance/Movement Therapy, Darrell Hyche

Expressive Therapies Capstone Theses

Black American youth are exposed to more death related circumstances than their peers yet are severely underrepresented in literature focused on the broader scope of children’s bereavement. More research and analysis are required to develop and implement culturally relevant interventions as they embark on their grief journey. Dance/movement therapy has the capacity for providing support that is culturally specific and able to meet the developmental levels of children, yet its grief focus work is limited. This literature review aims to bridge the gap between Black grief and dance/movement therapy as a culturally informed practice. An analysis of various forms of …

Regulation Through Rhythm: A Literature Review On Dance/Movement Therapy Approaches To Facilitating Nervous System Regulation, Elizabeth Barbera

Expressive Therapies Capstone Theses

Abstract

The mental health field has started to pay attention to how trauma plays into a person’s overall mental and physical well-being. Because of this more research has shown the connection between mind and body. Yet the clinical implications and literature on theories of how to treat trauma and trauma related disorders do not always connect. This review of literature seeks to analyze the literature on Porges’, Polyvagal Theory and Amighi’s, Kestenberg Movement Profiles. An investigation of the current literature makes a connection between the phylogenetic order of both the nervous system and developmental movement. Considerations of how trauma, in …
