Neuroanatomical And Morphometric Differences In Children Who Stutter, Mohammad A. Khan

Honors Scholar Theses

Childhood-Onset Fluency Disorder commonly known as stuttering is a neurodevelopmental speech disorder characterized by disruptions in speech fluency. While genetic and neurobiological factors are implicated, the structural brain differences underlying stuttering remain unclear. This study investigated neuroanatomical alterations in children who stutter (CWS) compared to typically fluent children (TFC), focusing on gray matter volume, cortical thickness, and surface area in speech-related regions; the Inferior Frontal Gyrus, Middle Temporal Gyrus, and Pre-motor Operculum. High-resolution MRI data from 100 children (48 CWS, 52 TFC) aged 3–12 years were analyzed using FreeSurfer. Group comparisons revealed no statistically significant differences in cortical thickness, surface …

The Relationship Between Adverse Childhood Experiences And Posttraumatic Symptomology In Rio Grande Valley Hispanic Adults, Timothy Hollinger

Walden Dissertations and Doctoral Studies

Childhood adversity is a known predictor of poor psychological outcomes in adulthood, yet little is known about this relationship among Hispanic adults in South Texas. This study examined whether adverse childhood experiences (ACEs) are associated with posttraumatic stress disorder (PTSD) symptoms and whether gender, marital status, or educational attainment moderate this relationship. The central research questions were: (1) What is the relationship between ACEs and PTSD symptoms among Hispanic adults in South Texas? and (2) Do gender, marital status, or education moderate this relationship? Guided by Bronfenbrenner’s ecological systems theory, this quantitative archival study used a non-experimental, correlational design. Linear …

Spousal Bereavement Enhances Proinflammatory Cytokine Production To Acute, Psychological Stress., E Lydia Wu-Chung, Ryan L. Brown, Robert Suchting, Jensine Paoletti-Hatcher, Michelle A. Chen, Angie S. Leroy, Kyle W. Murdock, Cobi J. Heijnen, Christopher P. Fagundes

Psychology Faculty Publications and Presentations

Early widowhood is characterized by chronic stress and is associated with a higher risk of incident depression and cardiovascular-related morbidity and mortality. Peripheral inflammation is involved in the pathogenesis of major depressive disorder and atherothrombosis and may represent a common mechanism underlying widow(er)'s elevated risk for both health conditions. Chronic psychological stress sensitizes the release of proinflammatory cytokines during the peripheral stress response. The present study examined whether recent spousal bereavement enhances the inflammatory response to an acute, psychological stressor. Recently widowed older adults (n = 143) and non-widowed controls (n = 69) participated in a quasi-experimental study, during which …

Poetries Of Abandonment: A Study Of Plath And Glück, Yara Abdelmoneim

Theses and Dissertations

This thesis explores the intersection between literature and trauma, which can be discerned in the key works of two poets, Sylvia Plath and Louise Glück. While offering readings of crucial poems, the thesis also examines the interrelations among trauma, memory and narrative as theorized by two contemporary psychiatrists, Bessel van der Kolk and Judith Herman. Both Plath and Glück wrote about personal and generational trauma after going through different experiences of abandonment. Absence, indirection and repetition provide the basis for literary techniques that allow their traumas to be better understood by authors and readers alike. The degree to which each …

Investigating The Impact Of A Social Media Literacy Intervention On Appearance Satisfaction, Life Satisfaction, And Affect, Jennifer Lai

Student Theses and Dissertations

Social media (SM) platforms are popular mediums for entertainment and connection among young adults, and the companies behind these platforms have intentionally designed and implemented features to enhance user engagement. Research has identified a negative relationship between SM use and mental health outcomes but few studies have tested SM literacy interventions to reduce the impact of SM use on these outcomes. To extend the literature on SM literacy interventions, this study sought to investigate the impact of a digitally-delivered SM literacy intervention on appearance satisfaction, life satisfaction, and affect. Participants were 125 students (M_Age = 20.50; SD = 2.79; …

Booked Or Buried In Texas: Risk Factors For Prebooking Suicide And Homicide Deaths Of Individuals With Sex Offenses, Nicole Moreira

Clinical Psychology Dissertations

Preventable deaths during law enforcement encounters, particularly those violent in nature, such as suicide and homicide deaths, are of considerable public concern. Prebooking, the law enforcement custody stage that includes arrest, serving warrants, wellness checks, traffic stops is often the most dangerous and fatal stage of custody. Despite being the most potentially dangerous and unpredictable of any custody stage, prebooking remains grossly understudied in comparison to jail and prison research, underscoring the need for focused research. To address this gap, the present study examines risk factors for suicide and homicide deaths among individuals with sex-related offenses during prebooking custody. Individuals …

Burnout, Life Satisfaction, And Meaning-Focused Coping In Correctional Mental Health Providers, Danielle Janet Tsamouris

Walden Dissertations and Doctoral Studies

Studies have found that burnout among correctional mental health providers is related to unique stressors that impact their physical, psychological, and emotional health, including the perceived and actual threat of violence. Using the transactional theory of stress and coping, the purpose of this quantitative study was to examine the influence of burnout and meaning-focused coping strategies on life satisfaction in correctional mental health providers. Online survey data from 102 master’s-holding correctional mental health professionals were recruited by SurveyMonkey who also administered the survey. Results from a standard multiple regression analysis suggested that meaning-focused coping strategies significantly and positively influenced life …

Changing The Narrative: A Meta-Analysis Of Narrative Therapy And It's Changes Since Inception, Elijah J. Shriner

Honors Projects

This meta-analysis examines the effectiveness of narrative therapy across 43 studies involving diverse populations and mental health conditions. Studies included randomized controlled trials, quasi-experimental designs, and case studies, with outcome measures primarily focused on depressive symptoms, interpersonal functioning, and psychological distress. Effect sizes were calculated using Hedges’ g to account for small sample bias. Overall, narrative therapy demonstrated moderate to large positive effects on symptom reduction and client well-being, though variability in study design and reporting limited the precision of some estimates. Findings support narrative therapy as a promising intervention across clinical contexts, while highlighting the need for more rigorous, …

Looking Forward To It: Investigating The Role Of Anhedonia In Episodic Future Thinking, Sarah Corner, Alicia E. Meuret

Psychology Theses and Dissertations

Episodic future thinking, or our ability to simulate personal future events, is implicated in a range of important functioning from problem solving to emotion regulation. However, individuals with clinical diagnoses like depression and schizophrenia struggle to produce future thinking that is vivid and detailed. While these deficits mirror well-document autobiographical memory deficits, they remain poorly understood. The current study aimed to examine the role of anhedonia in episodic future thinking vividness using a within-subjects dimensional approach. A mixed sample of sixty-five undergraduate students and community adults completed two future thinking tasks and one autobiographical memory across two study visits, during …

Examining Working And Episodic Memory In Young Adults With Anhedonia, Sofia Uribe

Psychology Theses and Dissertations

Depression is associated with impairments in memory processes. Evidence suggests there is poor recognition of positive information and quicker disengagement with positive information from working memory in depression compared to healthy controls. The working memory differences are hypothesized to be downstream effects of taxed working memory from rumination processes that impair reward learning. Furthermore, episodic memory impairments for positive information are hypothesized to be downstream effects of dopamine dysregulation from anhedonia in memory formation processes. The current study utilized the Diffusion Drift Model to examine whether anhedonia severity predicted differences in evidence accumulation using an index called drift rates in …

Misused And Misunderstood: Examining The Inappropriate Use Of Stimulant Medications, Connor Dains, Madilyn Paphanchith, Makayla Eversole, Chaehyeon Jin, Minhwan Yang, Joshua Honaker, Samantha Mccord, Kayla Petkus

Pharmacy and Wellness Review

Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder in children, characterized by inattention, hyperactivity, and impulsivity. The American Academy of Pediatrics (AAP) endorses stimulant medications as the first-line treatment option. When combined with behavioral therapy, this pharmacologic class can improve focus, executive functioning, and the overall quality of life. While stimulant prescriptions can have a positive effect when used as directed, there is concern for the potential of provider overprescription and patient misuse related to these medications. Consequently, the Food and Drug Administration (FDA) revised the boxed warning and prescribing information for stimulant medications. Healthcare providers must educate …

Icanfeel: A Digital Art Activity To Support Distress Detection In Adult Oncological Patients, Marie J. Deschamps

Expressive Therapies Dissertations

Considered the 6th vital sign, distress, a combination of hopelessness, anxiety, fear, and depression, can impact patients’ quality of life, treatment adherence, and mortality. While screening is required in oncological centers, distress remains under-detected. This study examined the use of Icanfeel, a novel digital art-based tool, to complement traditional psychometric assessments such as Edmonton Symptom Assessment System (ESAS), to support patients’ expressions of symptoms and distress detection. Hospitalized adult oncological patients (N = 22) engaged twice with Icanfeel and with an active control condition. At various time points during the protocol, patients self-reported symptom burden using ESAS, self-disclosure …

“It’S… Complicated:” A Literature Review On The Possibilities Of Using Drama Therapy To Improve Relational Functioning Of Emerging Adults With Complex Trauma, Sarah M. Drapeau

Expressive Therapies Theses

Interpersonal relationships play a crucial and complicated role in the mental well-being and development of emerging adults. Complex trauma has a significant negative effect on relational functioning, which plays an important role in post-traumatic growth, especially for emerging adults. This thesis reviewed current literature to outline the interaction between complex trauma and interpersonal relationships through the developmental lens of emerging adulthood. Empirical studies highlighted emotional (dys)regulation, attachment processes, and self-concept as mediating factors of this interaction. The literature reviewed offered current treatment approaches for this population, with connections that were relevant to drama therapy approaches. The literature showed that drama …

Why Disability Justice Matters In Mental Health Care And How Drama Therapists Can Help Get It Right, Anish Nakahara

Expressive Therapies Theses

Disability Justice (DJ) is an important, ever-growing aspect of mental health work that must be further explored and implemented if mental health professionals are committed to harm reduction and health equity. Drama therapy (DT) provides a unique accessibility that traditional psychotherapy does not always afford. The emphasis on encounters, relationality, and creative expression provides more avenues through which people can approach DT. Through analysis of current literature, this thesis explored the present relationship between DT and DJ, the relationship between the broader mental health care system and DJ, and how progress can continue toward competent, dignified care for disabled people. …

Emotional Pathways: A Literature Review Of Emotion Process In Emotionally Focused Therapy And Drama Therapy, Chiao-Ting Yuan

Expressive Therapies Theses

This capstone thesis explored how emotionally focused therapy (EFT), and drama therapy (DT) could be integrated to improve emotional regulation, self-awareness, and mental healing. Based on attachment theory and emotional process framework, how these two different but complementary interventions could increase emotional participation and transformation was explored. This literature review indicated that although EFT’s structured and verbal approach is different from DT’s creative and embodied skills, the two approaches share common goals and target the same emotional process. In DT, several techniques can be found that are closely related to EFT’s emotional process. These techniques can provide a unique and …

Exploring Biblical Language In Trauma Processing, Kathy B. Hoppe

Salubritas: International Journal of Spirit-Empowered Counseling

Clients may often find themselves struggling with accessing traumatic experiences in therapy, thereby developing an avoidance of trauma that impedes healing. Strategies for reducing trauma processing may be difficult to identify effectively. This project suggests several means by which therapists can utilize the language of scripture, including scriptural narrative, metaphor, and poetry, as a therapeutic intervention with conservative Christian clients who are pursuing trauma processing. The proposed approach assists clients in explaining their traumatic events in a secure setting, hence preventing the common hyperarousal symptoms that are upsetting. The treatment can enhance the effectiveness of evidence-based practices. It incorporates several …

Optimizing Accessibility Training By Prioritizing Cognitive Needs Of Students With Disabilities, Lio Jones, Kari Goin, Megan Mcfarland

Developmental Disabilities Network Journal

Despite the significant enrollment of students with disabilities in higher education, research and practice rarely center the voices and leadership of these students, particularly in accessibility training efforts. This paper addresses this gap by presenting an autoethnographic study of a digital accessibility training initiative co-led by a student with multiple disabilities. Using a process that combines participatory research and first-person narrative, this study outlines the development and implementation of faculty training on accessibility that centers the experiences of a student with cognitive disabilities. We propose a new framework for understanding "dynamic disability," a concept that recognizes the complex and evolving …

Connecting Through Context: A Culturally Relevant Mental Health Resource For K-12 School Counselors, Erica Knebel

Master's Projects and Capstones

This field project, Connecting Through Context: A Culturally Relevant Mental Health Resource for K–12 School Counselors, explores the intersection of decolonial theory, culturally relevant pedagogy, and school-based mental health practices. Rooted in both personal and academic experiences, the project addresses the significant gap in culturally responsive mental health resources for immigrant and refugee students, with a personal emphasis on those from Southeast Asian backgrounds. With nearly 27% of the U.S. student population being immigrants, traditional Western mental health models, centered on talk therapy and medication, often fall short in effectively supporting culturally diverse students. Through a literature review grounded in …

Alexithymia: A Review Of Existing Literature And A Prospective Route For Future Training, Jessica C. Friedman

Dissertations, Theses, and Projects

Alexithymia, a trans-diagnostic construct characterized by a disability to identify and articulate emotions, has received increasing attention within the medical and psychiatric communities due to its profound, negative impact on treatment outcomes. This paper provides insight into its complex and pervasive nature, its conceptualization and assessment, underlying neurobiological mechanisms and acquisition, extensive comorbidities, treatment implications, clinical manifestations, clinical considerations, and analysis of the existing body of research. While previous research assumed Alexithymia to be largely untreatable, recent publications have indicated its ability to be affected by emotional-awareness skill building and relationally based interventions, though no specific treatments for Alexithymia currently …

The Influence Of Incorrectly Labelled Ai-Generated Images On Subjective Feelings Of Truth And Memory, Tanner Mckenzie Grubbs

Theses and Dissertations

Artificial intelligence (AI) photo generators generated more than 15 billion images in the past year alone (Valyaeva, 2023). To subdue concerns about misinformation, many online platforms have mandated that content generated with AI be labelled as such (Bond, 2023), but the efficacy of these warning labels is largely unknown. Previous research shows that the presence of an image affects how much we trust the information we are exposed to, so we would expect these AI-generated images to influence people’s beliefs. The purpose of the present research was to examine how AI-generated warning labels influence people’s trust in claims presented with …

Gender And Age Differences Among Juvenile Homicide Offenders, Amanda Nichole-Wells Jabaay

Walden Dissertations and Doctoral Studies

The involvement of juveniles in homicide-related crimes has been a matter of growing public concern in the United States. Although prior research suggests that boys and girls who kill vary in important ways, there is limited research that has examined gender and age differences among juvenile homicide offender (JHO) characteristics and crime-related variables on a national level, with only eight previous national studies to date. Guided by the social control theory, the purpose of this non-experimental quantitative study was to explore gender and age differences among JHOs and other crime-related variables on a current national level. Archival data (N = …

The Organizing Role Of Function Knowledge In Scene Schemas, Teresa P. Pham

USF Tampa Graduate Theses and Dissertations

Schemata, or schemas, are conceptualized as “building blocks” of cognition that guide human information processing, object recognition, retrieval of memory, and more. Major work on schema theory was done in the 1970s, conceptualizing it as a useful framework for understanding how individuals organize knowledge and apply it to understand the world (e.g., Rumelhart, 1980). Research on schema theory has continued to have implications for reading comprehension, visual processing, and encoding and retrieval of memories. Despite the vast literature, the concept of schema itself remains loosely defined, with little consensus on how schemas are organized. This study explores whether function acts …

Education Behind Bars: Overcoming Barriers To Improve Outcomes, Daniel Costello

Counseling Psychology | Master's Theses

This thesis explores the transformative potential of correctional education in reducing recidivism and improving post-release outcomes for incarcerated individuals, nearly 68% of whom lack a high school diploma. Without foundational skills in literacy, numeracy, and critical thinking, reintegration into society becomes daunting, perpetuating cycles of poverty and incarceration. Despite its proven effectiveness, access to correctional education remains inconsistent, particularly for marginalized populations.

To address this gap, this project develops two specialized tutoring manuals: one for inmate peer-to-peer tutors and another for external volunteer tutors. The manuals provide culturally sensitive, practical strategies for teaching foundational skills and fostering personal growth. Peer …

Effect Of Response Bias On Threshold Estimates In Confounded N-Alternative Optional Choice Experiments, James J. Blaha, Benjamin T. Backus, Thaddeus B. Czuba

MODVIS Workshop

Three modifications of the familiar 2-AFC task can be useful when collecting data to estimate sensory thresholds from unpracticed participants: (1) Make responding optional, which relieves the participant from having to guess when they are uncertain; (2) Provide N>2 alternatives, which reduces the number of trials to estimate threshold; and (3) Confound the alternatives with an independent variable, for example by having participants choose visual field locations as alternatives when measuring threshold separately at each visual field location, which reduces the number of trials through multiplexing. The N-alternative optional-choice experiment (N-AOC) and its confounded variant have not been studied …

Connection Over Control: A Radically Open-Dialectical Behavior Therapy-Based Counseling Group For Avoidantly Attached College Students, Tara Pollnitz

Educational Specialist, 2020-current

Attachment avoidance is marked by a deep-seated mistrust of others, excessive self-reliance, and suppression of attachment needs. Feelings of boredom, disengagement, and uncertainty regarding how to proceed with treatment are common among practitioners treating avoidant clients. In this paper, the author examines attachment avoidance as a clinical concern, presents a conceptualization of attachment avoidance as a process related to emotional overcontrol, and explores the potential impact of intervention during college to provide a rationale for a counseling group to address attachment avoidance through radically open dialectical behavior therapy. Subsequently, the origins and theoretical foundation of radically open dialectical behavior therapy …

Mothers Supporting Mothers: A Psychotherapy Group For Postpartum Mothers Struggling With Substance Use, Brittany Hook

Educational Specialist, 2020-current

One topic that is not talked about enough is women’s health and more specifically postpartum women. This is apparent especially when it comes to postpartum care and the diverse experiences women face. The silence around postpartum women’s experiences can be frightening at times. The mental health of postpartum mothers can be overlooked and can lead to concerns of suicide ideation, increase substance use and a decrease in overall wellbeing. When substance abuse is in the picture for postpartum women, a treatment option that can be effective is group counseling. An evidence-based modality that works off the humanistic theory is motivational …

Lgbtqia+ Competency In Counseling: Understanding Current Trends, Educational Experiences, And Counselor Identity Implications, Tyler Puryear

Dissertations, 2020-current

This dissertation presents is made up of three manuscripts. The first is a systematized review that synthesizes current literature to better understand the definition, development, and gaps in LGBTQIA+ competency. Eleven major themes were identified: competency frameworks, cultural humility over competence, competence in practice, barriers, intersectionality, subgroups, advocacy, allyship, pedagogy, language, and counselor attitudes. Findings suggest the field must move beyond static competency models toward a cultural humility framework. The qualitative study used constructivist grounded theory (CGT) to explore how recent graduates from counseling programs experienced learning about LGBTQIA+ counseling topics. Five themes emerged: faculty influence on learning, experiential learning …

Assessing Examinee Effort: The Role Of Test Length In Low-Stakes Testing, Jonathan M. Henriques

Masters Theses, 2020-current

In the context of low stakes testing, where students have no benefits or consequences for their performance, test-taking effort becomes a central validity concern. Recent research has explored how shortening tests might improve effort. With modern planned missingness designs, it is possible to reduce the length of the test for the student without compromising the validity and reliability of the test. In this study, I investigated the impact of test length on effort using rapid guessing, a more contemporary technique that has not been applied to this research area. I randomly assigned students to one of three conditions: the full …

Navigating The Labyrinth: Transition Planning Process For Reintegration Of Inmates With Chronic Illnesses And Disabilities, Courtney Ashley Dean

Walden Dissertations and Doctoral Studies

Most offenders face challenges with successfully reintegrating, especially those living with chronic illness and/or disabilities. Transition interventions employed by mental health professionals are not universal and vary from facility to facility. While recidivism, community stigmatization, reoffending, and reconviction are explored in extant literature, little has been done to examine the difficulties faced by the professionals who work with this population as they get ready to plan for transitioning this disenfranchised group back into society. This study is an exploration of the role of professional counselors in facilitating successful transition planning for inmates living with chronic illnesses and/or disabilities. Guided by …
