The Resilient Mother: Exploring Factors That Buffer The Influence Of Early Childhood Trauma On Maternal Self-Efficacy, Brigid Magdamo

Electronic Theses and Dissertations

Childhood maltreatment and toxic stress pose significant risks to both individuals and communities, yielding negative outcomes that can perpetuate across generations— a phenomenon known as intergenerational trauma. Early intervention is imperative to disrupt this cycle of adversity and promote positive outcomes. One promising approach involves leveraging protective and promotive factors that cultivate resilience. Individuals with higher levels of benevolent childhood experiences (BCEs) and greater social support tend to exhibit enhanced self-efficacy, thereby potentially buffering the detrimental effects of childhood trauma. Furthermore, the perinatal period presents a critical juncture where maternal well-being significantly impacts both mother and child. The current study …

Examining Pain Catastrophizing, Mental Toughness, Self-Efficacy, And Perceived Pain In The Performance Of Female Athletes During Their Menstrual Cycle, Carissa R. Martinez

Electronic Theses and Dissertations

Pain is a universal unpleasant or negative experience influenced by physiological, psychological, and environmental factors. Disruption in the neural pathways of pain can affect athletic performance and lead to injury risks. Both negative attributes, such as stress, anxiety, and depression, and positive attributes, such as mental toughness and self-efficacy, contribute to pain perception and catastrophic thinking. The menstrual cycle also plays a critical role in pain catastrophizing, as hormonal fluctuations across different phases may hinder pain perception and performance in female athletes. However, research lacks the inclusion of how these factors impact female athletes. Using a non-experimental quantitative analysis, this …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Dropping Into The Expressive Art Therapy: A Community Engagement Arts Based Project, Sydney C. Smith, Meg Chang

Expressive Therapies Theses

This community engagement capstone explores how expressive arts practices (EXAP) may complement surf-based programming by supporting reflection, empathy, and meaning-making among participants. Research has demonstrated that surf therapy can promote emotional well-being, resilience, and social connection through embodied engagement with the ocean and supportive community environments. Integrating expressive arts practices within surf-based programs may extend these benefits by providing opportunities for reflection, creative expression, and interpersonal exchange. Grounded in expressive arts therapy (EXAT) theory and arts-based research (ABR) paradigms, this project examines how creative expression can support relational and emotional experiences within surf therapy settings. Using an arts-informed community engagement …

Behavioral Economic Factors Implicated In Young Adult Drinking In The Natural Environment: An Ema Study, Tatiana Magri

Graduate Studies Theses and Dissertations 2026

Background: Young adult (YA) alcohol use remains a prominent public health concern. Despite research efforts aimed at mitigating harms related to drinking, rates of alcohol use and adverse outcomes related to use, remain high among YAs. Previous research has identified alcohol demand, craving, and delay discounting as risk factors for problematic drinking among YAs. However, few studies have concurrently examined these constructs using methodologies that maximize ecological and contextual validity. Method: YA individuals (N=104) completed an ecological momentary assessment (EMA) protocol assessing three demand indices (i.e., intensity, Omax, and breakpoint), delay discounting, craving, and alcohol use and problems. Participants received …

Exploring The Impact Of Inpatient Mental Health Care On Adolescents, Alexandria M. Mckahan

2025 Fall Honors Capstones Projects - Archive

Adolescent psychiatric hospitalizations continue to rise, yet there is limited research on which daily practices inside inpatient units genuinely support engagement and recovery. This project examined how structure, staff tone, and therapeutic programming influence adolescents’ participation and emotional stability within a real inpatient setting. The study focused on three questions: how structured routines affect recovery, what challenges staff face when supporting adolescents with complex needs, and how adolescents’ engagement patterns reflect their perception of care. Using a mixed-methods case study at Mesa Springs Behavioral Health Hospital, I conducted approximately twenty field observations, semi-structured staff interviews, and descriptive engagement tracking across …

The Effect Of Need For Cognition & Need For Affect On Human Reliance And Artificial Intelligence Interactions, Aliyah Mcgowan

Doctoral Dissertations and Master's Theses

Abstract

With the increased use of Artificial Intelligence (AI) automations in fields like medical diagnoses and mental health queries, there are concerns regarding an individual’s trust and reliance on the technology. Reliance on AI output may lead an individual to accept inaccurate or incorrect information without further analysis. Trust may influence reliance and trust formation may be a product of affective processing. This study investigated the relationship between Need for Affect (NFA), Need for Cognition (NFC), and trust and reliance on AI interactions. Participants were assessed on the NFA scale for willingness to approach or avoid emotional stimuli, the NFC …

Archival data was analyzed using binary and multinomial logistic regression models to assess concurrent validity of specific subtests and indexes. Participants were grouped by ADHD subtype (inattentive, combined/hyperactive, or no diagnosis), with gender and executive functioning measures included in the models. Findings indicated that lower Cognitive Proficiency Index (CPI) and executive functioning scores (e.g., Animal Sorting, Response Set) predicted any ADHD diagnosis compared to the no diagnosis group, whereas higher CATA scores predicted lower Inattentive …

Subthreshold Depression In The National Epidemiologic Survey On Alcohol And Related Conditions Iii (Nesarc-Iii): A Quantitative Analysis Of Prevalence, Characteristics, And Burden In A Nationally Representative Sample, Scott T. Young

Antioch University Dissertations & Theses

While subthreshold depression (subD) is relatively young for a diagnostic concept at a mere half century old, it has burdened individuals and societies for far longer. Research has established that it is a highly prevalent, clinically important entity with clear links to personal distress and impairment (including increased suicidal ideation and behavior), societal burden (e.g., increased reliance on public assistance programs), and economic costs (both personal and public). Research has also demonstrated that it represents a significant risk factor for incident major depression (MD) and that it likely represents both a prodromal and residual state in the normal course of …

Learning Paradigms For Rhythm Detection And Generation Using Mathematical Models, Biophysical And Artificial Neural Networks, Prianka Bose

Dissertations

Humans possess an inherent ability to recognize evenly-spaced rhythms, known as isochronous rhythms, owing to the brain's predisposition to entrain to external auditory stimuli with regular temporal intervals. The central focus of this research is to understand how the brain learns and retains rhythmic time intervals in the context of music. This dissertation studies rhythm detection and generation through mathematical models, biophysical networks, and artificial neural networks, addressing both isochronous and non-isochronous patterns.

A primary focus of the thesis is on isochronous rhythms. In particular, given a perturbation to an isochronous rhythm such as a tempo change or phase shift …

Exploring Healthcare Chatbot Information Presentation: Applying Hierarchical Bayesian Regression And Inductive Thematic Analysis In A Mixed Methods Study, Samuel Nelson Koscelny

All Theses

High blood pressure, also known as hypertension, significantly increases the risk of heart disease and stroke, which are leading causes of death in the United States. While contributing to over 691,000 deaths in 2021 alone in the United States (U.S.), it also imposes immense economic burden on the healthcare system, costing approximately $131 billion annually. One way to address this issue is for increased self-care behaviors and medication adherence, both of which require sufficient health literacy. Despite the importance of health literacy, 90% of U.S. adults struggle with health-related subjects. Overcoming the issues associated with health literacy requires addressing the …

Measurement Invariance Of The Pandemic Anxiety Inventory In Different Demographic Groups, Irvin Sam Schonfeld, Tasmyn Prytherch, Mark Cropley, Jay Verkuilen, Renzo Bianchi

Publications and Research

Background The Pandemic Anxiety Inventory (PAI) was developed in the context of the COVID-19 pandemic. Its content allows it to assess anxiety in connection to any pandemic. Previous research has demonstrated the instrument’s reliability and validity. An important question for clinicians and researchers, however, remains open: Does the PAI have similar meaning for members of different demographic groups? The finding of measurement invariance would allow clinicians and researchers to comparatively assess pandemic-related anxiety across demographic groups, including favored and disfavored groups.

Methods We conducted a multi-group confirmatory factor analysis to assess the measurement invariance of the PAI using data obtained …

Embodied Co-Regulation: A Neuroregulatory-Informed Dance/Movement Therapy Transition Intervention Method For Arousal Regulation For Adolescents In A Partial Hospitalization Program, Anamaria Guzman

Expressive Therapies Capstone Theses

This thesis introduces a novel Dance/Movement Therapy (DMT) approach, focusing on nervous system arousal regulation during transitions between therapy groups. The core of the method involves a brief 5-minute exercise designed to modulate arousal levels, encompassing alertness and energy, aiming to establish a baseline homeostasis. Rooted in Polyvagal Theory and Developmental Neurobiology, the approach assumes the co-regulation of nervous systems within a group therapeutic setting. Two primary outcomes are self-assessed: 1) somatic experiences documented through narratives and 2) nervous system biodata measured using the Flowtime headband monitoring of brainwaves, heart rate, and other biomarkers. Results indicated that all six sessions …

Regression Discontinuity Designs Within A Latent Variable Framework: Measurement Considerations For The Accuracy Of The Treatment Effect, Sarah Hammami

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs are valuable quasi-experimental designs, especially when randomized control/clinical trials are ethically or practically challenging. Latent variables are prevalent in the social, behavioral, and educational (SBE) sciences—measurement assumptions have to be tested and met when using such variables. Not meeting those assumptions leads to biased results and (likely) erroneous inferential making. One way to minimize the impact of measurement assumption violation is to use latent variable modeling such as structural equation modeling (SEM). Soland, Johnson and Talbert (2022) conducted two simulation studies testing the effect of using a sum score (when the assumptions for using such a score …

Reframing Addiction As A Coping Response: A Needed Shift In Modern Public Health Paradigms, Anthony King

UNLV Theses, Dissertations, Professional Papers, and Capstones

What are the primary risk factors that compel one person towards addiction and not another? After decades of research, there is still no clear consensus. Some experts say addiction is a brain disease; others say it is a willful act, or even an outright crime. Nevertheless, the three research studies contained within this dissertation suggest an alternative, more parsimonious public-health-centered framework for viewing addictive behavioral patterns: as a biopsychosocial coping strategy for past and present stressors. In Study 1, this idea was examined by evaluating how symptoms of posttraumatic stress disorder (PTSD) were associated with problem gambling severity, different gambling …

Examining Stigma In Rural Mental Health Care Settings: A Mixed Methods Approach, Lainie Krumenacker

Murray State Theses and Dissertations

More than half of Americans will be diagnosed with a mental illness in their lifetime (CDC, 2021), yet stigma towards mental health affects both patients and providers. Although programs exist to address stigma, improve cultural competency among providers, and educate families on the importance of support, facilities are often limited on programs they provide due to allocation of resources and funds. Without a shift in treatment and programing, stigma will continue to impact patient care and outcome.

This study explored stigma among mental health providers in rural communities, while exploring potential differences in treatment among patients due to race. Mental …

Self-Conscious Emotions And The Right Fronto-Temporal And Right Temporal Parietal Junction, Adriana Lavarco, Nathira Ahmad, Qiana Archer, Matthew Pardillo, Ray Nunez Castaneda, Anthony Minervini, Julian Keenan

Department of Biology Faculty Scholarship and Creative Works

For more than two decades, research focusing on both clinical and non-clinical populations has suggested a key role for specific regions in the regulation of self-conscious emotions. It is speculated that both the expression and the interpretation of self-conscious emotions are critical in humans for action planning and response, communication, learning, parenting, and most social encounters. Empathy, Guilt, Jealousy, Shame, and Pride are all categorized as self-conscious emotions, all of which are crucial components to one’s sense of self. There has been an abundance of evidence pointing to the right Fronto-Temporal involvement in the integration of cognitive processes underlying the …

Emotion And Judgment In Young Women Of A Society In Transition, Maura A. E. Pilotti, Khadija El Alaoui

International Journal of Transpersonal Studies

The present study asked whether emotional responses to narratives of moral transgressions are shaped by the reader’s assumed relationship with the injured party (i.e., oneself, familiar other, and unfamiliar other). Its goal was to test a cultural, religious, and individualistic account of such responses in young females of a traditional society in transition towards a sustainable integration into the global economy. To this end, female college students from the Kingdom of Saudi Arabia were asked to identify their emotional reaction to each of several moral transgressions, report its intensity and then judge the severity of the transgression. In agreement with …

The Program To Reduce Implicit Bias In Carroll Hospital Center Using The Implicit Association Test, Katherine E. Traynor

Capstone Showcase

Natural brain processes make all individuals susceptible to unconscious bias; however, stressful, fearful, or anger-evoking situations as well as the negative influence of media and social surroundings increase the risk of holding obstructive bias, and there is a greater risk of being negatively impacted by this phenomenon when belonging to a minority population (Rose & Flores, 2020). As a result, high rates of infant mortality (10.2 deaths per 1,000 live births for the Non-Hispanic Black population compared to 4.1 in the White population) and cardiovascular related diseases (190.0 cases per 1,000 in the Non-Hispanic Black population compared to 161.3 in …

Prior researchers have explored how organizational climate and organizational commitment can contribute to or inhibit the decision to report misconduct. What remained unclear is how these factors may interact on their influence on employee silence. The purpose of this study was to examine whether organizational commitment mediated the relationship between organizational climate and employee silence. The theoretical foundations for this study were the social information …

Factors That Affect Anxiety And Acculturation In Syrian Emigrants, Thomas H. Anderson

Walden Dissertations and Doctoral Studies

Since the Syrian civil war began in 2011, more than 6 million Syrians have registered as refugees. Many displaced Syrians suffer myriad mental health disorders, including anxiety, which become a burden as they attempt to acculturate into a foreign culture. Research to understand the Syrian refugees has been conducted since the conflict began; however, the findings are inconsistent. Existing academic research does not adequately capture the depth of anxiety of Syrian emigrants, nor does it present an accurate picture of the challenges of acculturation. The purpose of this quantitative study was to examine the differences in anxiety and acculturation based …
