Dopaminergic Regulation Of Aversive Motivation, Elaine M. Grafelman

Dissertations (1934 -)

We all experience adversity in our lives, and we must be able to effectively respond to these challenges in order to thrive. One way to respond to stressors is to change one’s behavior to cope with the stress. This can include escaping or avoiding the stressor, focusing effort to diminish the effect of the stressor, or other coping strategies such as drug use. In fact, stress is one of the principal triggers of relapse for those in the abstinence phase of a substance use disorder and it exacerbates a variety of other disorders. Therefore, it is critical to understand the …

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 …

Understanding Medical Information And Emotional Support Needs In Mental Health Questions With Large Language Models, Chen Liu, William Yu Chung Wang, Gohar Khan

All Works

Purpose – This study seeks to bridge the gap between users’ multidimensional needs and the single-task capabilities of existing Mental Health Question Answering (MHQA) systems by tackling the underexplored challenge of jointly understanding medical informational needs and emotional support needs within complex consumer mental health inquiries. Design/methodology/approach – Grounded in Rhetorical Structure Theory (RST), the proposed Multi-Needs and Context Recognition (MNCR) framework decomposes mental health question understanding task into four interrelated subtasks: Medical Needs Recognition (MNR), Medical Needs-related Context Extraction (MNCE), Emotional Needs Recognition (ENR) and Emotional Needs-related Context Extraction (ENCE). A new benchmark dataset, MHQ-MedEmo, was constructed through multi-layered …

The Dream We All Share, Austin C. Pence

Student Works

We all dream about the same things— owning a home, traveling where we want, and taking care of the people we love. For a lot of us, that feels far away. 1 Original Graphic by Austin Pence, Source: Investor.gov, U.S. government resource providing financial education and investment tools. After all, we’re college students. Between tuition, housing, and Taco Bell runs, saving for retirement feels about as real as gray hair.

But here’s the truth: the earlier you start saving— even just a few dollars a month—the easier your financial life becomes later. You don’t need to be rich to start; …

This quantitative, retrospective cross-sectional study explored the social and contextual factors influencing hypertension among this vulnerable population. Using the 2019 Behavioral Risk Factor Surveillance System dataset, which included a sample size of 2,060 participants, the study examined the relationship between hypertension and key variables including primary care utilization, health insurance, smoking, physical activity, mental health, and marital status, while controlling for age, education, and income. Guided by the health belief model, binary logistic regression analyses found health insurance and primary care utilization significantly …

Investigating Dysfunctional Cognition Change As A Putative Mechanism Of Cbt For Youth Anxiety, Ocd And Ptsd: Protocol For An Individual Participant Data Meta-Analysis, Brooke Levis, Philip C Kendall, Eric A Storch, Lynn Mobach

Faculty, Staff and Students Publications

Introduction: Anxiety disorders, obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) are common in children and adolescents and can lead to significant impairment. Cognitive behavioural therapy (CBT) with exposure is the first-line treatment, yet approximately half of treated youth do not achieve full remission. Dysfunctional cognitions-negative automatic thoughts, maladaptive beliefs and distorted interpretations-are considered key targets of CBT, but evidence in youth is mixed and underpowered. This study will examine whether change in dysfunctional cognitions mediates treatment outcome in anxiety, OCD and PTSD symptoms and whether this association varies across individual characteristics.

Methods and analysis: An individual participant data meta-analysis …

Walden Dissertations and Doctoral Studies

The Texas Department of Criminal Justice (TDCJ) faces employee retention challenges, and recruiting and retaining correctional officers remains TDCJ’s most significant challenge and highest priority. Correctional facility leaders need to understand these challenges as indicators of workforce sustainability. Grounded in job embeddedness theory, the purpose of this general qualitative study was to explore the turnover experiences of Texas correctional officers, to understand why officers left their jobs, and the factors that contributed to their decisions to stay in their jobs. Participants comprised 11 former correctional officers who had worked between 5 months and 6 years for the TDCJ. Data were …

Nativism As The Engine Of Fear Toward “Illegal” Immigrants, Amilie Cai

Student Scholar Symposium Abstracts and Posters

Contemporary concerns about “illegal” immigration reveal deep-seated anxieties about race, cultural, and national identity in the United States. In this paper, I examine how xenophobia, media consumption, and Christian nationalism collectively shape fear of illegal immigrants. I build upon previous literature, such as the Group Threat Theory, which posits that dominant groups mobilize to preserve social hierarchies when their status is threatened, and the Agenda-Setting Theory, which emphasizes the media’s power to shape public perceptions. Using Wave 11 of the Chapman Survey of American Fears–a nationally representative sample of U.S. adults collected in 2025–I provide a comparative analysis of these …

Loneliness And Support For Political Violence Within The United States, Kellen Downey

Student Scholar Symposium Abstracts and Posters

Although loneliness is a growing public health issue in the United States, its political effects remain understudied. This paper seeks to understand the relationship between loneliness and the support of political violence by utilizing the Chapman Survey of American Fears (CSAF Wave 11). This survey, which is a component of the 2025 Chapman Survey of American Fears, includes the three-item UCLA Loneliness Scale, as well as two separate items specifically measuring political violence. Using a national survey (N=1,015), I address the following questions: (1) Are lonely individuals more likely to support violence on political grounds? (2) Does strongly identifying with …

Medicaid Funding And Health-Related Social Needs: A Policy Analysis, Passion Ilea

Dissertations and Theses

The U.S. has disproportionately high health care spending compared to other high-income nations and comparatively poor health outcomes. The Centers for Medicare and Medicaid Services (CMS) have recently increased emphasis on addressing Medicaid member social needs. CMS believes addressing health-related social needs (HRSN) may reduce costs and improve health outcomes for Medicaid members. CMS has begun to test theories regarding the impact of member HRSN on health care by designing federal mechanisms to address HRSN, such as in lieu of services and settings-funded services, and by encouraging state Medicaid programs to develop their own approaches, such as Flexible Services.

Teaching Dental Public Health Using A Socially Accountable Approach, Anastasios Plessas, Martha Paisi, Nilufar Ahmed, Zoe Brookes, Robert Witton

Peninsula Dental School

Traditional approaches to dental public health education across Europe remain dominated by lecture-based learning which often fail to cultivate critical reflection on inequities, privilege, and the broader social determinants of oral health. Social accountability has been recognized as core competency for dental graduates, requiring dental professionals to align professional practice with the health needs of communities. Community-engaged education is a promising pedagogical model that situates learning within real-world contexts, fosters empathy, cultural competence, and advocacy skills, and strengthens professional identity formation. This paper discusses the Peninsula Dental School’s innovative model, which integrates community engagement, reflective practice, and interprofessional education within …

Neighborhood Disorder And Psychosocial Functioning: Evidence Of Resilience Among Racial/Ethnic Minority Groups, Maverick E. Morales

Student Scholar Symposium Abstracts and Posters

Perceived neighborhood disorder has been linked to poor well-being. In the United States, racial/ethnic minorities are more likely to live in disordered neighborhoods than non-Hispanic White residents. However, it is unclear whether this exposure changes the relationship between perceived neighborhood disorder and psychosocial functioning. Racial/ethnic minorities may draw upon sources of resilience (e.g., religiosity/spirituality), protecting them from neighborhood disorder. Using data from the Health and Retirement Study, the present study examined perceived neighborhood disorder and psychosocial functioning (i.e., life satisfaction, anxiety, perceived stress, and loneliness) to test the following hypotheses: (1) higher perceived neighborhood disorder will relate to worse psychosocial …

Revisiting The Link Between Metacognition And Social Cognition, Mia I. Gaffoglio, Jojo Widi, Aaron Schurger

Student Scholar Symposium Abstracts and Posters

Research has suggested that the ability to think about our own thinking (metacognition) and the ability to understand others’ mental states (mindreading) may rely on the same cognitive resources. A study by Nicholson and colleagues (2021) found that people’s metacognitive accuracy decreased when they performed a mind-reading task at the same time, implying that the two processes interfered with each other. However, that conclusion is dependent on the assumption that the mind-reading task and a control task were equally difficult. If the mind-reading task was more difficult, having a lower performance could reflect general task difficulty rather than shared cognitive …

Exploring The Potential For Data Storytelling Practices In Healthcare Communication, Shafaq Zehra, Naomi Jacobs, Dan Richards

IASDR Conference Series

The key challenges associated with the design of doctor-patient communication mainly include time constraints, cultural and language barriers and health literacy of the patients accessing care. The implications of the gaps in effective doctor-patient communication may lead to lack of compliance to treatment, weakened rapport building and lack of trust in the healthcare services. This paper qualitatively explores the context of the challenges associated with doctor-patient communication from a health care provider perspective. The main themes identified by in-depth interviews with clinicians were issues related to lack of trust, validity of patient’s information, lack of patient engagement and empowerment, and …

A Practical Introduction To The Method Of Blending Through Pattern In Weft-Knitted Stripe Structures To Improve The Overall Tactility Of Breed-Specific Wool Fibres., Wilmott Julia, Gaston Elizabeth, James Alana

IASDR Conference Series

The paper introduces ‘blending through pattern’, a method for significantly enhancing the tactile qualities of individual British broad wool fibres when combined in knitted fabrics. This approach is an alternative to traditional blending processes, such as spinning and twisting, because it utilises weft-knitted pattern structures to combine two, three or more yarn types together. Each yarn type is knitted through a single feeder, with the blending occurring in the same way that a pattern on the knitting machine combines different colours. Successfully blended fabrics exchange yarn types regularly to incorporate different fibre types effectively. This material-led approach to textile design …

Designing For Interprofessional Collaboration: Integrating Data And Communication In Health Care Teams, Tzu-Ling Huang, Ko-Chiu Wu

IASDR Conference Series

As holistic health care gains momentum within medical systems, interdisciplinary collaboration has become crucial to improving the quality of patient care. In practice, however, cooperation among professionals is often hindered by fragmented information, differences in professional language and logic, system discontinuities, and the lack of structured processes. This study investigates the needs and challenges of information integration and task tracking in interdisciplinary teams through qualitative interviews and a card-sorting method with seven types of healthcare professionals— physician, nurse, medical social worker, clinical psychologist, dietitian, physical therapist, and dentist. The findings highlight issues such as insufficient information integration, fragmented goal-setting and …

From Function To Culture: Exploring Senior-Centered Design Principles In Korean Context, Sujin Song, Miso Kim, Min Ju Kang, Ye In An, Soojin Jun

IASDR Conference Series

South Korea, as the fastest-aging country in the world, occupies a critical position in aging research. Designing for older adults requires a multidimensional understanding; however, existing studies on design principles for aging have tended to adopt functionalist approaches focused primarily on physical and cognitive decline. In response, this study proposes design principles that center on values systems rather than offering directly prescriptive or procedural guidance. Specifically, we introduce culturally responsive principles grounded in Korea’s unique socio cultural context. Drawing on a co-design workshop with Korean older adults and caregivers, our analysis engages narratives through the lenses of Korea’s rapid industrialization, …

Designing Personalized Digital Self-Control Tools To Address Procrastination Through Co-Design, Youngsoo Shin, Jeremy D. Faulk, Jungkyoon Yoon

IASDR Conference Series

Procrastination, a pervasive challenge among college students, significantly affects mental health, academic performance, and overall well-being. While Digital Self-Control Tools (DSCTs) are commonly used to manage procrastination, existing solutions and studies often fail to address the nuanced, individualized factors that drive this behavior. This study employs a co-design approach to explore how DSCTs can be personalized to better support college students. Over a nine-week co-design project, twenty-two students in the HCI field collaboratively developed personalized DSCT concepts, guided by the Motivation, Engagement, and Thriving in User Experience (METUX) model. The METUX model provided a theoretical basis for designing interventions that …

Co-Living With Intelligent Artifacts: An Experiential Participatory Speculative Design Method, Boyu Zhang, Jiaxin Xiao, Li Zhang

IASDR Conference Series

With the advancement of artificial intelligence and robotics, intelligent artifacts are increasingly integrated into human life. Traditional user-centered design approaches focus on optimizing interaction experiences but often overlook potential ethical issues. This study employs a participatory speculative design approach, engaging the public in co-constructing future scenarios to foreground ethical reflection at the early stages of the design process. Building on this approach, we propose an extended model of the Experiential Future Ladder and implement it through a workshop involving eight Chinese youth participants. Thematic analysis identifies three categories of ethical issues in future human–intelligent artifact interactions: dilemmas between emotion and …

From Trauma To Transformation: A Cognitive-Embedded Design Framework For Responsive Healing Environments, Xiujun Chen, Ziyuan Jiang

IASDR Conference Series

Post-conflict architectural interventions often overlook survivors’ altered cognitive and emotional landscapes. This paper introduces cognitive-embedded design—a framework that reconceives architecture as an active participant in collective healing. The study adopts a speculative, research- through-design approach integrating conceptual inquiry with spatial and technical prototyping. Using the redesign of Sarajevo’s Grbavica Market as a case study, it demonstrates how sensor-driven spatial systems can support trauma recovery when orchestrated through Judith Herman’s three-phase model and 4E cognition principles. The project integrates responsive boundaries, bio-adaptive narratives, and culturally rooted craft spaces that attune to healing rhythms while preserving user agency through community governance. While …

Making In Metaphor: Critical Intersectional Outfitting Framework, Eduardo Féteira, Danika Van Kaathoven, Tomohide Mizuuchi, Daijiro Mizuno

IASDR Conference Series

Strategies that allow for an in-depth and multi-layered analysis and approach to wicked problems are increasingly crucial in today’s design education environment. Intersectionality presents itself as an articulated and analytical tool that effectively frames interconnected and mutually-reinforcing forces. But within design practices, it still lacks visual ising and making processes that allow for a more tangible understanding of its core principles and highlight its benefits in identifying inflexion points of action within problem spaces. This paper introduces the Critical Intersectional Outfitting (CIO) framework, an educational tool which aims to facilitate wider visualisation of problem spaces through a compartment ali sed …
