There’S Cardio And There’S Cardio: How Fitness And Sexual Attitudes Relate To Needs For Approval And Loneliness, Isaac Robertson Dec 2025

There’S Cardio And There’S Cardio: How Fitness And Sexual Attitudes Relate To Needs For Approval And Loneliness, Isaac Robertson

Honors College Theses

This study looked to collectively investigate the relationships of both fitness/sexual activity attitudes with a need for social approval, while also determining if biological sex could play a role in either of these relationships. Additionally, loneliness and mental well-being were examined with the aforementioned variables. Predominantly white (82.5%) females (75%) data were analyzed after completing an online survey (N = 40). Significant relationships were found between fitness attitudes and a need for social approval in women only (r (28) = -.50, p = .005) and between sexual activity attitudes and a need for social approval in men only (r (8) …


Bearing The How: Self-Compassion, Religiosity, And Basic Psychological Needs As Predictors Of Meaning In Life, Benjamin Wenndorf Dec 2025

Bearing The How: Self-Compassion, Religiosity, And Basic Psychological Needs As Predictors Of Meaning In Life, Benjamin Wenndorf

Doctor of Psychology (PsyD)

While meaning in life (MIL) has been established as a significant contributor to psychologists’ understanding of wellbeing (Pollet & Schnell, 2017; Steger et al., 2008; Steger et al., 2011), some theorists believe MIL to be the fundamental human drive (Frankl, 1946/1962). Despite the significance that has been placed on MIL as a core component of human existence, little research has explored more than one variable at a time in relationship to MIL. Recent literature has explored self-determination theory’s (SDT) basic psychological needs microtheory as a predictive model for understanding MIL within a greater context of positive psychology (Martela et al., …

Learned Resiliency: Lived Experiences Of First Responders, Kevin Francis Sullivan Dec 2025

Learned Resiliency: Lived Experiences Of First Responders, Kevin Francis Sullivan

Walden Dissertations and Doctoral Studies

Scholarly literature has found that post-traumatic stress impacts first responders; however, little attention has been paid to how first responders learn resiliency through post-traumatic growth (PTG). The purpose of this hermeneutic phenomenological study was to explore a gap in the literature of first responders who learned resiliency through posttraumatic growth following a critical incident in the line of duty. The research study was grounded in Heidegger’s philosophy of hermeneutic phenomenology, guided by resiliency theory , and informed by post-traumatic growth theory. Seven first responders from multiple disciplines were invited to participate in semi-structured interviews designed to provide rich and reflective …


Netflix And Kill: The Role Of True Crime Consumption In The Development Of Acquired Capability For Suicide, Chandler Jayne Mcdaniel Dec 2025

Netflix And Kill: The Role Of True Crime Consumption In The Development Of Acquired Capability For Suicide, Chandler Jayne Mcdaniel

Theses and Dissertations

The Interpersonal-Psychological Theory of Suicide (IPTS) identifies acquired capability as a key factor contributing to suicidal behavior. Previous research has shown that violent media exposure can increase suicidal risk through desensitization, imitation, and trauma activation. However, little is known about the role of true crime consumption (TCC), a popular form of violent media engagement, in relation to IPTS constructs. This study examined whether TCC predicts acquired capability for suicide, perceived burdensomeness, and thwarted belongingness. A total of 215 participants were retained after data cleaning. Hypotheses predicted that higher TCC would be associated with higher acquired capability (H1), that TCC would …

A Functional Mri Meta-Analysis Encoding In Alzheimer’S Disease, Joanne Ha Dec 2025

A Functional Mri Meta-Analysis Encoding In Alzheimer’S Disease, Joanne Ha

Master's Theses

Alzheimer’s disease (AD) is the most common form of dementia and is characterized by episodic memory impairment. Numerous functional magnetic resonance imaging (fMRI) studies have examined brain activity differences between individuals with AD and age-matched controls during memory encoding. However, small sample sizes and methodological variability across studies have limited the ability to draw meaningful conclusions regarding brain activity underlying encoding impairments. We conducted a meta-analysis to identify consistent patterns of hyperactivity and hypoactivity in AD during episodic memory encoding. Using PubMed to identify studies that met our inclusion criteria, 1,002 studies were screened; ultimately, seven studies were included in …


The Timing Of Pubertal Onset Affects Adults Anxiety Behavior In A Sex-Specific Manner, Evan Raubenolt Dec 2025

The Timing Of Pubertal Onset Affects Adults Anxiety Behavior In A Sex-Specific Manner, Evan Raubenolt

Honors Projects

This study aims to look at the relationship between the timing of pubertal onset and its long-term effects on adult anxiety behavior in rats. Though the topic of pubertal onset has been frequently discussed in developmental research, its exact effects have been inconsistent. Human models have shown that early and late maturing males are associated with a notable increase in adult anxiety behavior, while in rat models, similar sex-specific effects regarding anxiety have been demonstrated, though those studies focus on a causal relationship between exposure to stress and age of pubertal onset. This study first aims to examine that relationship …


Closeness, Conflict, And Achievement: The Role Of Parent–Child Relationships In Homeschooled And Public-Schooled Children, Celeste Gonçalves Tomaz Dec 2025

Closeness, Conflict, And Achievement: The Role Of Parent–Child Relationships In Homeschooled And Public-Schooled Children, Celeste Gonçalves Tomaz

Honors Capstones

The parent–child relationship has been found to be a predictor of children’s academic and socio-emotional outcomes, with parent-child closeness linked to motivation and persistence (Mo & Singh, 2008; Silinskas & Kikas, 2022) and parent-child conflict associated with emotional and behavioral difficulties (Dotterer et al., 2008; Pinquart, 2017). The homeschooling context may increase these associations since children spend more time with their parents, who have caregiving and instructional roles (Padilla, 2021; Thomas, 2016). Even with growing research on academic and socio-emotional outcomes, few studies have examined whether the strength of the parent–child relationship is influenced negatively or positively by schooling type. …

Examining The Relationship Between Trust-Based Relational Intervention® (Tbri®), Placement Stability, And The Voluntary Placement Disruption Of Minor Children In Substitute Caregiving Environments, Kelsey Tiernan-Coleman Harrison Dec 2025

Examining The Relationship Between Trust-Based Relational Intervention® (Tbri®), Placement Stability, And The Voluntary Placement Disruption Of Minor Children In Substitute Caregiving Environments, Kelsey Tiernan-Coleman Harrison

Doctoral Dissertations and Projects

Placement stability is associated with positive outcomes for minors in substitute caregiving environments. Numerous variables are related to placement stability, but there is a paucity of data highlighting specific interventions that improve placement stability. Trust-Based Relational Intervention (TBRI)® has been studied extensively in child welfare populations, with promising results, including improved caregiver-child attachment and decreased child internalizing and externalizing behavior, psychiatric symptomology, and caregiver burnout and stress. However, TBRI® has not been studied exclusively in relation to placement stability. This mixed-methods design study examined the relationship between TBRI®, including the degree and timing of exposure, placement stability, and voluntary placement …


Cognitive Behavioral Therapy: The Relationship Between Diet, Anxiety, And Depression And The Moderating Effect Of Cbt, Deborah J. Wright Dec 2025

Cognitive Behavioral Therapy: The Relationship Between Diet, Anxiety, And Depression And The Moderating Effect Of Cbt, Deborah J. Wright

Doctoral Dissertations and Projects

This study examined how cognitive behavioral therapy (CBT) techniques including cognitive restructuring and positive affirmations affect the relationship between dietary patterns and depression and anxiety symptoms. Research has established that CBT and diet affect depression and anxiety independently, but less research examines their collective impact. The study included 154 adult participants who filled out the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7 alongside a Dietary Habits Checklist and a CBT Engagement Checklist during the previous two weeks. The results from multiple linear regressions showed no statistically significant moderation effects of CBT engagement on the relationship between diet and depression …


Changing How Foster Care Begins: A Qualitative Study To Assess The Success Of One Specific Nonprofit, Madeline Ewoldt Dec 2025

Changing How Foster Care Begins: A Qualitative Study To Assess The Success Of One Specific Nonprofit, Madeline Ewoldt

Doctoral Dissertations and Projects

Most foster parents feel they do not receive adequate emotional support, funding, and preparation for their foster children in their care, which can lead to turnover, placement disruptions, and additional unnecessary caregiver changes for foster children. Attachment Theory explains children need consistent, warm, and loving caregiver relationships for healthy emotional, cognitive, and social development (Bowlby, 2018). For children in foster care, these relationships are already disrupted, therefore intervention for foster parent resiliency must be analyzed. The Bible calls Christians to care for the orphans, which leaves a large responsibility on Christians to care for those in foster care. There is …


A Phenomenological Study Exploring The Common Themes Among Individuals Who Have Broken Generational Cycles Of Conflict Avoidance, Codependency, And People Pleasing, Joseph Daniel Mcginnis Dec 2025

A Phenomenological Study Exploring The Common Themes Among Individuals Who Have Broken Generational Cycles Of Conflict Avoidance, Codependency, And People Pleasing, Joseph Daniel Mcginnis

Doctoral Dissertations and Projects

Many healthy and unhealthy adult behaviors are transmitted from parent to child as generational behavior cycles. Conflict avoidance, codependency, and people-pleasing are all unhealthy relationship dynamics that are generationally passed down in such a way. Breaking these generational cycles of unhealthy relationship dynamics is often difficult. The goal of this phenomenological qualitative study was to explore the common themes among individuals who have broken the generational cycles of conflict avoidance, co-dependency, and people-pleasing. The study consisted of 17 participants who were identified as having broken the generational cycles of conflict avoidance, codependency, or people-pleasing. Each participant was either previously involved …

Exploring The Relationship Between Loneliness And Real-Time Measurements Of Gsr And Hrv During Concept Mapping, And Cortisol And Oxytocin Levels, Jangwon Seo Dec 2025

Exploring The Relationship Between Loneliness And Real-Time Measurements Of Gsr And Hrv During Concept Mapping, And Cortisol And Oxytocin Levels, Jangwon Seo

Masters Theses

This study attempts to explore loneliness among college students from a bio-physio-psycho-social perspective, and it utilizes real-time physiological measurements (GSR and HRV) and biomarkers (cortisol and oxytocin) in conjunction with psychosocial assessments. The study employs both qualitative and quantitative methods, which involve concept mapping exercises, with the aim of comprehending the full nature of how loneliness interacts with physiological and psychological processes. At Time 1 (T1) we found significant positive correlations between loneliness and elevated GSR levels, which is indicative of increased sympathetic arousal (r = .35, p < .01). Additionally, there were significant negative correlations between loneliness and mean RR intervals in HRV that indicated autonomic dysregulation featured by increased sympathetic activities as well as reduced parasympathetic functions (r = -.28, p < .05). However, at Time 2 (T2), these correlations were not significant indicating possible temporal fluctuations due to adaptive responses or extraneous variables such social support systems or coping mechanisms. The qualitative data from concept mapping enriched the analysis by providing deeper insights into the cognitive and emotional processes underlying loneliness. Despite limitations like demographic skewness, funding constraints, logistical challenges, etc., this, therefore, highlights the need for multidimensional investigations of psychological phenomena. This has implications for future research as well as clinical practice, which could include using these integrative measures to develop holistic interventions for mental health disorders.


An Examination Of Psychosocial Factors Related To Male Serial Killers, Rachael Elizabeth Tubbs Dec 2025

An Examination Of Psychosocial Factors Related To Male Serial Killers, Rachael Elizabeth Tubbs

Walden Dissertations and Doctoral Studies

Historically, studies on serial murderers have not concentrated in depth on analyzing what psychosocial factors are or how they could influence a man to become a serial killer. The focus of this qualitative study was on the psychosocial characteristics of male serial killers that are from, and based in, the United States. Using a case study analysis approach, the life course of serial killers in the FGCU Radford Database was analyzed to identify themes of adverse childhood experiences such as physical, emotional, or psychological abuse; abandonment by parent or guardian; limited or no social bonds; witnessing abuse; and signs of …


Narratives Of Sexual Self-Esteem As A Domain Of Sexual Well-Being In Cisgender Women’S Long-Term Intimate Relationships, Lisa Criswell Dec 2025

Narratives Of Sexual Self-Esteem As A Domain Of Sexual Well-Being In Cisgender Women’S Long-Term Intimate Relationships, Lisa Criswell

Walden Dissertations and Doctoral Studies

Only within the last few decades has female sexual health become a topic of focus for researchers and practitioners to begin focusing on, leading to a gap in research between female sexual health and male sexual health. This has led to lack of knowledge and understanding on female sexual dysfunction and how interventions can effectively address it. An identified gap in knowledge of female sexual health and self-esteem is the lack of understanding of female narratives. This study was developed with the purpose of filling that gap and addressing domains within sexual health and self-esteem through exploration of the narratives …


Sex, The Body, And Learning Gender: Demons In The World Of The Five Gods, Erin E. Mcbrien Dec 2025

Sex, The Body, And Learning Gender: Demons In The World Of The Five Gods, Erin E. Mcbrien

Mythopoeic Society Seminar Proceedings

“Sex, the Body, and Learning Gender” analyzes the relationship between the physical body, sexual orientation, and gender as characterized within Lois McMaster Bujold’s World of the Five Gods series, with a particular emphasis on her Penric and Desdemona novellas. Using the framework of Bussey and Bandura’s social learning theory, and a close reading of Bujold’s text, this paper explores how the demonic characters within this series are an example of gender as a learned concept rather than a biological imperative. This is further developed by examining how the demonic characters both imprint on and contrast against the more societally-bound sorcerers …

Behind Closed Doors, Beyond The Cell: Supporting Children Of Incarcerated Parents, Averi R. Amaro

Honors Program Theses and Research Projects

This study examines the overlooked population of children affected by parental incarceration and evaluates intervention programs designed to support them. Grounded in Labeling Theory (Becker, 1963), Self-Fulfilling Prophecy (Merton, 1948), and the Restorative Justice framework (Zehr, 2002), this study explores how stigma, expectation, and repair shape the outcomes for the youth affected by parental incarceration. Drawing from qualitative and quantitative research, it analyzes the emotional, social, and educational effects of incarceration on families, identifying protective factors such as attachment, mentoring, and community support that mitigate delinquency risks. Program evaluations of Girl Scouts Beyond Bars, Parenting Inside Out, Project Avary, and …


Comparing Profiles Of Impairment Among Children With Dmdd, Adhd, And Odd, Joanna Christmas Dec 2025

Comparing Profiles Of Impairment Among Children With Dmdd, Adhd, And Odd, Joanna Christmas

All-Inclusive List of Electronic Theses and Dissertations

Disruptive Mood Dysregulation Disorder (DMDD) has a high comorbidity rate with ADHD (Bruno et al., 2019), meaning that many children referred for ADHD evaluation may also meet criteria for DMDD. Additionally, the two disorders can have some similarity in how they present. Thus, clinicians who frequently assess children for ADHD could benefit from being aware of how measures commonly used in ADHD evaluations can also be useful in identifying characteristics of DMDD as well as patterns of impairment more specific to DMDD. The present study explored possible differences in parent and teacher ratings of child peer impairment as well as …


Mi Cuerpo, Mi Salud: A Brief Sexual Health Pilot Intervention For The Promotion Of Latina Sti Testing, Ariana Cervantes-Borges Dec 2025

Mi Cuerpo, Mi Salud: A Brief Sexual Health Pilot Intervention For The Promotion Of Latina Sti Testing, Ariana Cervantes-Borges

Open Access Theses & Dissertations

Disparate rates of sexually transmitted infection (STI) contraction among Latinas and emerging adults highlight glaring public health issues that warrant brief and digital STI testing interventions to promote service acquisition. Latinas may experience a greater negative impact of STIs compared to men, indicating a need to target this population group. Prior studies have noted STI testing intentions and acquisition in Latina populations to be largely impacted by four components: education, stigma, social support, and self-efficacy. Given recent funding cuts for STI research, a brief and digital intervention may circumvent costs associated with traditional intervention implementation. The current study aimed to …


Observed Parenting, Parent-Child Aggression, And Intimate Partner Violence As Predictive Of Family Dysfunction, Paige Munshell Dec 2025

Observed Parenting, Parent-Child Aggression, And Intimate Partner Violence As Predictive Of Family Dysfunction, Paige Munshell

Psychology Theses & Dissertations

Family systems theories contextualize violence as occurring across multiple levels of the family, yet much of the existing literature focuses on a single family member’s outcome (i.e., the child) and neglects to include data collected from fathers. This study examined the associations between indicators of functioning at the dyadic-level in the family system—observed parenting, Intimate Partner Violence (IPV) perpetration, and Parent-Child Aggression (PCA) risk—and later overall family dysfunction. Participants were 180 mothers and 144 of their male partners evaluated when their child was 18 months old and re-evaluated at 4 years old. Measures of observed parenting, IPV perpetration, and PCA …


Schema, Stigma, And The “We-Them” Divide: Perspectives On Ageism From Everyday Life To Healthcare, Temple D. West Dec 2025

Schema, Stigma, And The “We-Them” Divide: Perspectives On Ageism From Everyday Life To Healthcare, Temple D. West

English Theses & Dissertations

Ageism remains a pervasive and often underexamined form of discrimination, affecting older adults across both everyday and clinical contexts. This paper explores how cognitive schemas—mental frameworks that shape perception and experience—and stigma interact to reinforce a “we–them” divide between and older patients and healthcare providers, as well as between older and younger individuals in broader society. Through focus groups and listening to the voices of older patients, this study examines how assumptions of age-based decline are embedded in society and inform schemas of ageism. It considers how those schemas shape the spoiled identity of older people as a stigmatized group, …


Associations Between Trait Mindfulness And Distress In Fertility Patients: Evidence From Two Clinical Samples, Amanda Dillard, Brian Meier, Todd Williams, Michael Wolfe, Mili Thakur Dec 2025

Associations Between Trait Mindfulness And Distress In Fertility Patients: Evidence From Two Clinical Samples, Amanda Dillard, Brian Meier, Todd Williams, Michael Wolfe, Mili Thakur

Psychology Faculty Publications

Women who experience fertility problems often report high levels of distress. Trait mindfulness, or the tendency to be present-minded and accepting of one’s thoughts and feelings, could offset this distress. Aims: In two cross-sectional studies, we tested if fertility patients who were higher in trait mindfulness were lower in psychological distress as measured by anxiety and depressive symptoms, fertility-specific distress, and anticipated negative emotions. Method: Study 1 (N = 324; Age M = 34.3; 90% White) included women who had recently sought treatment for fertility problems, and Study 2 (N = 102; Age M = 32.9; …


An Investigation Of Collateral Activity Effects On Behavior Maintained By A Drl 72‑Second Schedule, Cassidy M. Graham Dec 2025

An Investigation Of Collateral Activity Effects On Behavior Maintained By A Drl 72‑Second Schedule, Cassidy M. Graham

Masters Theses

Impulsivity is a key behavioral trait with broad implications for clinical disorders such as Attention Deficit Hyperactivity Disorder ADHD, and substance use disorders SUD, where impaired inhibitory control contributes to maladaptive outcomes. In preclinical research, animal models provide valuable tools for examining behavioral processes associated with impulsivity. The Differential Reinforcement of Low Rates (DRL) schedule, offers a precise measure of response inhibition and timing by requiring subjects to withhold responses for reinforcement. This study employed DRL72s schedule to investigate impulsive action in male and female Sprague-Dawley rats, with an emphasis on sex-based differences and the potential influence of environmental factors. …
