The Role Music Plays In Facilitating Transformation And Self-Actualization In Israeli Music Students Impacted By Trauma, Adina Feldman Jan 2026

The Role Music Plays In Facilitating Transformation And Self-Actualization In Israeli Music Students Impacted By Trauma, Adina Feldman

Educational Studies Dissertations

Abstract

This qualitative study explores the role music plays in facilitating transformation and self-actualization among Israeli undergraduate and alumni music students who have experienced trauma or post-traumatic stress disorder. Guided by social constructivist and humanistic-existential frameworks, this research employs a narrative methodology to examine how music operates as a medium for meaning-making, resilience, and growth in non-clinical contexts. Data were collected through in-depth interviews, participant observations, and the analysis of musical compositions and artifacts from two singer-songwriters who transformed personal adversity into creative expression. The findings reveal that although trauma leaves lasting psychological and emotional effects, engagement with music enables …


“I Don’T Want To Be The Bad Kind Of Special”: The Lived Experiences Of Autistic Youth In Extracurricular Programs In Their Communities, Catherine A. Sargent Ph.D. Jan 2026

“I Don’T Want To Be The Bad Kind Of Special”: The Lived Experiences Of Autistic Youth In Extracurricular Programs In Their Communities, Catherine A. Sargent Ph.D.

Counseling and Psychology Dissertations

Autistic youth face barriers to participation and belonging in community settings. Historically, autism research has privileged researcher perspectives and deficit-based frameworks, often excluding the authentic voices of autistic individuals, particularly young people. This qualitative, phenomenological study sought to address that gap by exploring the lived experiences of autistic youth (ages 13–18) participating in extracurricular community programs in Massachusetts. Framed by critical disability theory, critical autism studies, ecological systems theory, and intersectionality, the study examined how autistic youth experience inclusion, connection, and self-expression within programs designed largely for neurotypical participants.

Seven autistic youths contributed to this research through participant-generated photographs and …


Internalized Transnegativity, Self-Warmth, Self-Coldness, And Eating Disorder Symptomatology Among Transgender And Nonbinary Adults, Sarah Mcarthur, Suzanne Mclaren, Peter D. Goldie Jan 2026

Internalized Transnegativity, Self-Warmth, Self-Coldness, And Eating Disorder Symptomatology Among Transgender And Nonbinary Adults, Sarah Mcarthur, Suzanne Mclaren, Peter D. Goldie

Department of Psychology Faculty Scholarship and Creative Works

Eating disorders (EDs) are highly prevalent among transgender and nonbinary (TNB) adults, and internalized transnegativity is a key risk factor for ED symptomatology. Although extant literature has established that self-compassion protects against EDs among the cisgender population, research among TNB adults is nascent. The current study sought to identify whether internalized transnegativity and components of self-compassion (i.e., self-warmth and self-coldness) were independently associated with ED symptomatology, and whether the components of self-compassion moderated the relation between internalized transnegativity and ED symptomatology. An international sample of 127 TNB adults aged between 18 and 69 years (M = 32.24, SD = …

Drug Education: The Gaps In Rural Versus Urban Communities, Madilyn Mages Jan 2026

Drug Education: The Gaps In Rural Versus Urban Communities, Madilyn Mages

Honors Capstone Projects

Drug education is often lacking in rural communities due to lack of access and lower quality of education causing an increase in youth using substances and drug overdoses. Looking at previous research, there is a definite gap in rural and urban adult and youth substance use. The research showed that higher levels of education show less risk of substance use issues. Research also looked at new programs and how they worked in urban areas to decrease risky substance use behavior. This is a call for new programs to be created for rural communities due to their differences. This research explores …

Findings revealed strong support for individualized rooms, normalized environments, and increased positive human interaction as transformative …


Investigating The Reliability And Validity Of The Social Connectedness Instrument Among U.S. Adults, Blake A. Fraser Jan 2026

Investigating The Reliability And Validity Of The Social Connectedness Instrument Among U.S. Adults, Blake A. Fraser

Doctoral Dissertations and Projects

Growing evidence shows that poor social connectedness is becoming a public health threat, with rising prevalence and connections to poor mental and physical health across the lifespan. Therefore, there is an urgent need to develop feasible and effective social connectedness interventions. There is limited evidence for the effectiveness of current interventions, with studies recommending tailoring the intervention to an individual’s specific social connection needs. However, previous measures of social connectedness provide little information about potentially modifiable contributors of poor connection. Thus, the Social Connectedness Instrument (SCI) was developed to fill in this gap by proposing two novel latent constructs of …

As face-to-face interactions decrease, the opportunities and challenges of technological and digital advancement further the complexity of remote work. Leaders serve as prominent figures who use remote technology to communicate and interact with employees that report to them. The relationship between remote work and the development of meaningful social interactions remains largely unexplored (Clark et al., 2018). This phenomenological study explored the described experiences of remote leaders, the role that identity development plays in the success of leadership remote work, how their identity development impacts their well-being and …

Doctoral Dissertations and Projects

Childhood trauma encompasses experiences such as abuse, neglect, and household dysfunction, experiences which have profound and lasting effects on an individual’s development and well-being. These behaviors can manifest in many ways. The intricate interplay between childhood trauma, mental health challenges, and maladaptive behaviors creates a complex clinical picture, often requiring specialized and trauma-informed approaches within the community. Understanding the efficacy of interventions tailored to this population is crucial for improving the quality of life and fostering resilience. Despite extensive research, there remain significant gaps in understanding the full scope of these effects and how to mitigate them. This study investigated …


The Relationship Between Religiosity, Meaning-Making, And Well-Being Among Involuntary Childless Women, Laura Beth Harter Jan 2026

The Relationship Between Religiosity, Meaning-Making, And Well-Being Among Involuntary Childless Women, Laura Beth Harter

Doctoral Dissertations and Projects

The proportion of involuntary childless women in the United States continues to rise, with research indicating elevated risks of depression, anxiety, and diminished well-being in this population compared to their childbearing counterparts. Simultaneously, many faith communities emphasize pronatalist ideals, which may compound these psychological effects. Despite a growing body of qualitative work, quantitative research examining faith, meaning-making, and well-being among women whose childlessness extends beyond recent infertility is limited. This quantitative, correlational study examined the relationships among religiosity, meaning-making, and well-being among involuntary childless women. Participants (N = 94; M age = 44.6) completed online surveys including the Duke University …

Unmothered: A Phenomenological Study Of Black Daughters Who Are Detached From Their Black Mothers, Imani S. Steele

Doctoral Dissertations and Projects

Mother-daughter relationships are often characterized as foundational, nurturing bonds, but for some adult daughters, the relationship is a source of pain and disconnection. This phenomenological study explored the lived experiences of adult Black American daughters who are detached from their Black American mothers, influenced by Bowen Family Systems Theory’s emotional cutoff concept. Seventeen Black adult women, aged 27-49, were interviewed to assess how they made meaning of being detached from their mothers, along with the ways it shaped their lives. Findings showed that detachment was a gradual response to a history of harmful mothering. Daughters described detachment as an act …


Racial Bias, Mindfulness, And Motivation Among Mental Health Clinicians, Deirdre Y. Burton Jan 2026

Racial Bias, Mindfulness, And Motivation Among Mental Health Clinicians, Deirdre Y. Burton

Doctoral Dissertations and Projects

Racial bias is linked to poor mental health outcomes and obstructs clinician-client relationships. Mental health clinicians (MHCs) may express implicit bias, expanding disparities for people of color. Mindfulness and motivation to respond without prejudice (MRP) are associated with reduced racial bias, yet few studies have examined these constructs among MHCs. Therefore, the purpose of the study was to evaluate relationships between mindfulness, MRP, and implicit racial bias. Licensed MHCs (n = 47, 85.1% female, 59.6% African American, mean age 50 years) participated in a convergent parallel mixed-methods study involving an online survey [Race Implicit Association Test (Race IAT), the Five …

Using the Kruskal–Wallis H and chi-square tests, the study assessed the potential relationships among parenting styles, biblical use in parenting, and parent-perceived problem-solving skills of their …


Bridging Theory And Self-Development In Human Services And Counselor Education, Kristy Carlisle Jan 2026

Bridging Theory And Self-Development In Human Services And Counselor Education, Kristy Carlisle

Journal of Human Services Scholarship and Interprofessional Collaboration

Counselor and human services education increasingly recognize self-awareness as a core component of professional competence and ethical practice. This conceptual manuscript presents a pedagogical framework that integrates major helping theories as tools for structured self-reflection and self-development among students and practitioners.

By engaging in guided reflective activities, students examine personal beliefs, emotions, and behaviors to enhance self-understanding, …


The Relationships Between Ego Depletion And Social Behaviors Across Different Degrees Of Psychological Flexibility, Jacob Cage Norris Jan 2026

The Relationships Between Ego Depletion And Social Behaviors Across Different Degrees Of Psychological Flexibility, Jacob Cage Norris

Masters Theses

Social behavior includes behaviors that are influenced, directly or indirectly, by the realistic, anticipated, imagined, or implied presences of others. Particular social behaviors such as altruism or aggression may vary in how accessible they are, depending on the degree of self-control that has been recently exerted. Specifically, self-control fatigue, or ego depletion, seems to make aggression more likely and altruism less. However, individuals who are psychologically flexible, or who tend to be in contact with the present moment while engaging in behaviors that support the pursuit of values may not respond to ego depletion with the same changes to social …

The Role Of Isotocin In Female Zebrafish (Danio Rerio) Reproductive Behavior And Its Implication For Intranasal Oxytocin Therapy In Humans, Katelynn M. Benge

Masters Theses

In the past several decades, oxytocin has been colloquially termed the “cuddle hormone,” due to its role in pair-bonding and monogamy (Carter et al., 1992). In addition to being used experimentally for psychological disorder, it has also been used in couple’s counseling settings (Anagnostou et al., 2014; Domes et al., 2016). The outcomes of this research reveal mixed results, creating a need for further research in the topic to understand the exact mechanisms by which oxytocin works in the brain to induce this prosocial response.

Adaptable Psychopathic Traits: Military And Para-Military Organizations, Mariana Ramirez Jan 2026

Adaptable Psychopathic Traits: Military And Para-Military Organizations, Mariana Ramirez

Student Theses

Although culturally distinct, both military and law enforcement careers demand individuals to operate effectively in high-risk environments; a characteristic shaped through processes of military and para-military occupational socialization, reinforced by an adaptable personality. Understanding the distinctions between military and law enforcement cultures provides a foundation for examining individual-level factors such as personality, behavior, and mental health. Recent research (e.g. Anestis et al., 2019; Batastini et al., 2023; Falkenbach et al., 2017; Falkenbach et al., 2018; McKinley & Verona, 2023; Patton et al., 2018; Preston et al., 2020; Roșca et al., 2021) has increasingly applied a psychopathic framework to study these …


Psychological Experiences Of Law Enforcement Officers Responding To Critical Incidents Alone And With A Partner, Lydia Abernethy Jan 2026

Psychological Experiences Of Law Enforcement Officers Responding To Critical Incidents Alone And With A Partner, Lydia Abernethy

Walden Dissertations and Doctoral Studies

The role of law enforcement officers is to restore peace and safety when chaos occurs, which can be life-threatening and stressful as officers respond to the critical incidents unfolding. For this study, a qualitative approach and phenomenological framework were utilized to gain insight into the first-hand psychological experiences of officers responding to critical incidents. Police officers work in demanding environments that can lead to mental health conditions such as depression and post-traumatic stress disorder. Peer support and communication among coworkers have emerged as a potentially important factor, as officers would share traumatic events with other officers. Therefore, my research focused …


Wilderness Therapy As An Intervention For Teens Who Are At The End Of Their Rope, Blake C. Neal, Heather Summers Jan 2026

Wilderness Therapy As An Intervention For Teens Who Are At The End Of Their Rope, Blake C. Neal, Heather Summers

Lynchburg Journal of Medical Science

Abstract

Wilderness therapy, treatment offered in a natural setting, is offered as an alternative to traditional treatment methods (Lodato, N., Blivas, R., & Blivas, N. L. and R., 2024). This model is often used as a last resort for teens who are unsuccessful in other environments. However, when used as a blanket treatment model for all mental health concerns, there is a risk for greater harm inflicted on participants. A case study approach provides evidence of a teen in one of these settings struggling with an eating disorder and self-harm. Although potentially helpful with some concerns, we learn from this …

Aphasia severity after stroke varies widely and is not fully explained by lesion size or location. We propose that incorporating the brain’s sensorimotor-association (S-A) gradient, reflecting cortical hierarchy, offers a biologically grounded framework for predicting language outcomes. In 236 individuals with chronic left-hemisphere stroke, we examine whether the hierarchical position of lesions in language-specific (LS) and domain-general (DG) areas modulates aphasia severity. We parcellate lesions using a cortical atlas and weigh them by each region’s S-A rank. We apply hierarchical linear regression to test whether S-A ranking and its interaction with lesion volume improves prediction of Western Aphasia Battery-Revised Aphasia …
