Evaluating The Motivations Of Participants In Online Equine Extension Courses, Sarah Vos

Department of Animal Science: Dissertations, Theses, and Student Research

Traditional program evaluations emphasize participant demographics, knowledge gain, behavior change, and program impact. However, evaluating participant motivation can provide addition insight into why participants enroll in extension programs and help explain participant engagement and persistence throughout a program. The purpose of this study was to evaluate participant motivation in two online equine extension courses and examine potential relationships between motivation, demographics, and course delivery method, and describe participant engagement in Virtual Horse Judging Camp (VHJC). This cross-sectional study utilized convenience sampling of participants in two online equine extension courses, Horse Adult Leader Training and Educational Resource (HALTER) and VHJC. The …

Investigation Of A Novel Behavioral Assessment Of Challenging Behavior In The Context Of Medical Necessity And Disability Theory, Madison S. Walker

All NMU Master's Theses

Individuals with neurodevelopmental disabilities often engage in challenging behaviors that interfere with daily functioning and community participation. Many standardized assessments focus on indirect, descriptive measurements that emphasize frequency, while providing limited information about medical severity, ongoing management strategies, and functional outcomes. This misalignment may limit the clinical utility of assessments, as scores may not consistently align with medical necessity criteria or arguments supporting the maintenance of current treatments. The first study extends on Reyes-Martín et al. (2022), which reviewed 24 assessments of challenging behaviors, by further evaluating assessment characteristics relevant to clinical decision-making and treatment justification. Findings highlight variability across …

Impact Of Repeated Serotonin 6 Receptor Activation On Weight And Anxiety In C57bl/6j And Btbr Mice, Pedro Flores

Electronic Theses, Projects, and Dissertations

Selective Serotonin Reuptake Inhibitors (SSRI) are the most common form of medication prescribed to people with anxiety disorders. One of the most common side effects is weight gain. This weight gain often leads to the suspension of treatment. This has led to studies focusing on specific serotonin (5-HT) receptor targets for modulating depression and anxiety. Studies examining 5-HT6 antagonist treatment have shown that they reduce body weight as well as produce brain specific changes. Less is known regarding 5-HT6 receptor agonists, although previous literature has shown that exposure to high doses produces weight loss but not at lower doses, while …

Role Of Stigma On Engagement In Mental Health Services For Latinxs With First-Episode Psychosis (Fep), Livia J. Padron Briceno

Electronic Theses, Projects, and Dissertations

Psychotic patients often endure stigma in their daily lives (Corrigan, 2018). Psychotic patients are understood as individuals who are experiencing psychotic symptoms such as hallucinations, delusions and disorganized speech (Arciniegas, 2015; Breitborde et al., 2017; Moskowitz et al., 2019) and have been diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria with a psychotic disorder (e.g. Schizophrenia, Schizoaffective Disorder). Stigma refers to negative perceptions held about an individual experiencing mental illness. While public stigma refers to the negative views adhered to by members of communities (e.g., sociocultural group, family units) about people with mental illness, self-stigma …

The Price Of Possessiveness: How Parental Materialism Undermines Child Psychological Wellbeing, Miao Li

Sociology Publications

Materialism, a value system that places the pursuit of possessions at the core of happiness and life meaning, is a dominant cultural force in modern societies. While its associations with individual well-being are well-documented, its intergenerational implications remain understudied. This study conceptualizes materialism as a potential family stressor contributing to the intergenerational transmission of stress. An intergenerational crossover model of materialism was tested using data from 1,996 parent-child pairs in Zhengzhou, China. Results indicate that higher parental materialism is associated with stronger materialistic values in children, weaker family relationships, and more frequent parental comparisons, each of which is linked to …

Understanding College Student Expectancies Of Simultaneous Engagement In Multiple Risk Behaviors: A Measurement Development And Model Testing Study, Shelby Whalen

Electronic Theses and Dissertations

Risky behaviors, actions that may cause physical, psychological, social, or economic harm to oneself or others, are prevalent among college students. While significant research has focused on single high-risk behaviors of alcohol use, drug use, gambling, and gaming separately, students frequently engage in multiple high-risk behaviors simultaneously, such as drinking alcohol while gambling. Research shows that students have distinct and specific expectancies about what happens when they engage in a risk behavior, however, minimal research has examined students’ perceptions or reasons for simultaneous poly-risk behavior engagement. This multi-phase project characterized students’ outcome expectancies for simultaneous poly-risk behavior combinations, developed and …

The Memphis Gambling Screen: A Clinical Validation Study Of An Enhanced-Readability Self-Report Measure For Gambling Disorder, Natasha Bourgoin

Electronic Theses and Dissertations

Precise identification of gambling disorder can be difficult when commonly used screeners vary in clarity and diagnostic accuracy. The Memphis Gambling Screen (MGS) was developed as an enhanced-readability self-report measure to improve item comprehension and strengthen the diagnostic accuracy of DSM-5 gambling disorder. This study evaluates the psychometric properties and diagnostic accuracy of the MGS with a combined sample of individuals seeking treatment for problem gambling or substance use disorder and college students with a recent history of gambling (N = 232). Participants completed a demographic questionnaire, the MGS, and another commonly used measure, the Problem Gambling Severity Index …

"Always Online, Never At Ease: Fear Of Missing Out (Fomo) As A Partial Mediator Between Adverse Childhood Experiences (Aces) And Physical Health, Psychological Functioning, And Psychosocial Adjustment Among College Students", Evelyn Pensamiento

Psychological Science Undergraduate Honors Theses

Adverse Childhood Experiences (ACEs) are potentially traumatic events, such as abuse, neglect, and household disruption, that occur during the first 18 years of life. ACEs have been found to be strongly linked to negative outcomes, such as poor physical health, poor mental health, low self-esteem, low emotion regulation, poor college adjustment, low life satisfaction, and low social connectedness, and high loneliness (Felitti et al., 1998; Carbonell et al., 2018; Cloitre et al., 2019; Mosley-Johnson et al., 2018; Yayan et al., 2019). Previous literature suggests that fear of missing out (FoMO) may help explain some of the negative consequences of ACEs …

Sexual Grooming And Other Barriers To Disclosure Of Childhood Sexual Abuse, Lillian A. Steedman

Theses, Dissertations and Culminating Projects

Child sexual abuse is a serious and prevalent problem in the United States and is associated with negative consequences across numerous life domains (e.g., psychological, physical, socioeconomic). Disclosure of sexually abusive experiences may facilitate victims’ abilities to obtain psychological, social, and legal support. It has been theorized that sexual grooming plays a role in decreasing the likelihood of disclosure and of disclosures being believed. Therefore, this dissertation examined associations among sexual grooming, other barriers, and disclosure decisions and timing. Participants were recruited and screened online for eligibility to participate in a survey examining details of the abuse, trauma-related shame, disclosure …

Seeing The Unspoken: A Pilot Eye-Tracking Study Of Moral Injury Among Veterans, Eva M. Valdez

Dissertations

This pilot study examined associations between self-reported moral distress, state distress, combat exposure, deployment history, and maximum pupil reactivity among veterans diagnosed with PTSD. Participants viewed neutral and morally relevant images while pupil responses were recorded using eye-tracking technology. Self-report measures included moral distress severity, exposure to potentially morally injurious events, Subjective Units of Distress Scale (SUDS) ratings, total deployments, number of combat deployments, and Combat Exposure Scale scores. Maximum pupil reactivity was calculated by subtracting the mean z-scored maximum pupil response during neutral image presentations from the mean z-scored maximum pupil response during morally relevant image presentations. This variable …

Intergenerational Trauma And Grief Among The Latine Community: Proposed Interventions And Treatment Considerations, Alexandra M. Johnson

Dissertations

The intersectionality of bereavement, trauma, and culture has many clinical considerations, including the impact on individuals and families. Traumatic events can impact an individual directly, collectively, and intergenerationally. The Latine community is one of the largest cultural groups in the United States, and mental health treatment often includes several cultural considerations. This critical literature review examined how the Latine community has been impacted by intergenerational trauma, specifically through experiences of grief and loss, to inform clinical focus, case conceptualization, and identify gaps in the literature. The first chapter provides a brief history of the intersectionality of intergenerational trauma and bereavement, …

Dissertations

Middle Eastern and North African (MENA) immigrant students who are seeking to earn a higher education in the United States have to navigate acculturative stressors and systemic barriers. Prior research has focused primarily on the challenges MENA immigrant students experience without deeply exploring how these students adapt and grow. The focus in this qualitative study was to understand how MENA immigrant college students experience and make meaning of their academic journeys. Semi-structured interviews were used to explore the academic experiences of seven MENA immigrant college students in the United States and assess how acculturative stressors, personal strengths, coping strategies, and …

Black Protection: Black Social Media Competency And Urban, Black Adolescents On Social Media, Taylor A. Williams

Dissertations

While urban, Black adolescents interact with racial identity content on social media, their identity is primarily shaped through offline experiences and later reflected or reinforced online. Through the concept of Black social media competency (B-SMC), this study examined the relationships between Black urban adolescents’ social media use, exposure to race-related content, and experiences navigating the digital environment. The study used a qualitative design, grounded in the phenomenological and ecological frameworks, with 21 adolescents recruited from two urban, Midwestern schools and programs to participate in semi-structured interviews, and data were analyzed using thematic analysis to identify patterns in how the participants …

Love’S Dialects: Proposed Additions In Emotionally Focused Therapy For Intercultural Couples, Nicola Heurich

Dissertations

Intercultural romantic relationships have become an increasingly prominent feature of contemporary society due to globalization, migration, and cross-cultural exchange (Livingston & Brown, 2017). However, these partnerships are also associated with elevated levels of relational distress and higher rates of conflict, separation, and divorce, underscoring the need for culturally responsive approaches in couple therapy (Bustamante et al., 2011; Genç & Su, 2021).

Research on intercultural couples remains limited both within and beyond Emotionally Focused Therapy (EFT), and despite increased recognition of cultural factors, there is still insufficient guidance on navigating differing cultural contexts within a dyad (Linhof & Allan, 2018).

A Critical-Constructivist Grounded Theory Exploration Of The Mental Health Experiences Of Individuals With Intellectual Disabilities In Post-Secondary Settings, Alyssa L. Decker

Dissertations, 2020-current

Individuals with intellectual disabilities (ID) now have access to higher education, often through inclusive post-secondary education programs (IPSE), to increase employability and quality of life. IPSE programs, historically, have provided academic and life skill support and not mental health support within programs’ curricula. A recent review of IPSE programs reveals that if mental health services are included, they are often accessed through university health services. Transitioning from high school to college induces high levels of stress, which can exacerbate underlying mental health conditions. Mental health care is defaulted to an already overburdened college counseling center without the knowledge and skills …

The Augmented Matching Law, Matias A. Avellaneda

All Graduate Theses and Dissertations, Fall 2023 to Present

Every living organism, including humans, has a finite amount of time available: 24 hours in a day, 365 days in a year, and a certain number of years in its life. At every moment, such an organism will be engaging in one of a multitude of possible activities, such as eating, sleeping, or reading this dissertation. We use the term choice to denote the way in which the organism distributes its time among all these activities, and some of these choice patterns are more beneficial to the organism than others, showcasing the importance of understanding the mechanisms underlying choice. A …

Vulnerability In The Dark Triad: Insecure Attachment And Relational Aggression In The Peer Relationships Of College Students, Summer Boggs

Dissertations

Research on relational aggression (i.e., a type of aggression in which the aggressor harms others by damaging their relationships, reputation, and/or feelings of social acceptance) with college students has identified several important correlates, including anxious and avoidant attachment styles. Moreover, the personality traits captured by the Vulnerable Dark Triad (VDT; i.e., borderline, the antisocial component of psychopathy, and vulnerable narcissism; Miller et al., 2010) have demonstrated positive relationships with both relational aggression and insecure attachment. This study examined the relationship between insecure attachment and relational aggression among college students (N = 560), testing VDT traits as partial mediators of …

Testing P300-Based Biometric Authentication Paradigms, Jordan Razzak

Electronic Theses and Dissertations

Bench research suggests that P300 amplitude is greater in response to self-relevant stimuli compared to familiar stimuli. This effect could enable a novel method of biometric authentication based on the self-relevant P300. This dissertation aims to: (1) determine the optimal presentation paradigm for leveraging self-relevance in P300-based biometric authentication, and (2) investigate P300 responses from self-relevant stimuli versus stimuli learned over the course of a week.

Two presentation paradigms were compared – rapid serial visual presentation (RSVP) and matrix presentation (MP). Participant-specific RSVP and MP classifiers were trained by applying stepwise linear discriminant analysis to data collected during presentations of …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

Supporting Every Student: Optimizing School-Based Mental Health Services For Students With Intellectual Disabilities, Sarah K. Eggleston

Educational Specialist, 2020-current

Youth with intellectual disabilities (ID) are at considerably greater risk of developing mental health problems compared with the general population; however, their needs are less likely to be identified, and they often face barriers to accessing quality mental health care. School-based mental health professionals (SBMHPs) are uniquely positioned to support students within their natural learning environments, where many common barriers to service provision have been removed. The present study examined the current state of practice among SBMHPs in Virginia in identifying and supporting the needs of students with ID, as well as SBMHPs’ training experiences. An online cross-sectional, mixed-methods survey …

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

The Legacy Of Trauma: Exploring The Effect Of Generational Stress On Gut Health And Mental Well-Being In Black Women, Jocelynn Jones

Dissertations

This dissertation examines how generational trauma and chronic stress may relate to gut health and mood outcomes among Black women. Using a literature review design, this work brings together research on intergenerational trauma, gendered racism, Superwoman Schema, weathering, allostatic load, mood disorders, reproductive health disparities, and the microbiota-gut-brain axis. The central argument is that depression, anxiety, gastrointestinal symptoms, fatigue, reproductive vulnerability, and healthcare mistrust should not be understood as fully separate concerns when they may be shaped by shared stress conditions. The proposed integrated model does not claim that trauma directly causes gut dysbiosis or mood disorders. Instead, it suggests …
