Gene-Environment Interactions In Cardiovascular Aging: Volunteering, Polygenic Risk, And Biomarker Change In European And African Ancestry Populations, Seoyoun Kim, Byeongju Ryu, Erin Ware, Koichiro Shiba, Cal J. Halvorsen

Brown School Faculty Publications

Volunteering has been associated with better cardiovascular health, but whether this association varies by genetic susceptibility to cardiovascular disease remains unclear. This study examined associations between volunteering and cardiovascular biomarkers, assessed associations between biomarker-specific polygenic scores (PGSs) and these outcomes, and tested whether polygenic risk moderated volunteering–biomarker associations among U.S. adults aged 51 years and older.

Connected But Disconnected: A Covid-19 Youth Participatory Action Research Study, Vianney Atugonza, Jodi Dworkin, Stacey S. Horn, Joanna A. Tzenis, Samantha Lebouef

Journal of Youth Development

In 2020, the COVID-19 pandemic forced most schools across the U.S. to close and transition to remote learning. Families were forced to transform their homes into classrooms while facing challenges to their health, finances, and social connections. To better understand how young people experienced these changes, a Youth Participatory Action Research (YPAR) project was employed to engage young people in naming, exploring, and sharing their experiences during this time. Nine high school youth leaders were trained as researchers to conduct interviews with their peers. These youth scholars were also trained on how to code, sort, and disseminate data and results. …

Exploring 21st-Century Skills In A Summer Camp: A Qualitative Methodological Triangulation Approach, Alexander Bowman, Jing Song

Journal of Youth Development

Despite the recognized importance of 21st-century skills and the substantial body of research on these skills, little is known about how to identify growth in these skills. The lack of reliable methods to measure 21st-century skill growth presents a challenge for the design of relevant learning environments and for evaluating if such learning environments are effective. Using a qualitative methodological triangulation approach, this study explored camp counselors’ learning processes. Using a systematic data integration method, field observations were synthesized with participant reflections about how their skills develop. Data were collected from 13 high-school-aged junior camp counselors at a summer camp …

Becoming Who I Am: How Youth Leadership Experiences Shape Lifelong Leadership Journeys, Dustin Evatt, Deborah Acker, Parker R. Watson, Jennifer T. Peters

Journal of Youth Development

Youth leadership experiences have the power to shape individuals’ values, identities, and leadership behaviors well into adulthood, yet limited empirical research has examined how these formative experiences contribute to leadership development over time. This study examines the long-term impact of youth leadership experiences using the six-stage Leadership Identity Development (LID) model as a guiding and interpretive framework by exploring the journeys of alumni from the Shelton Challenge, a six-day immersive high school leadership program at NC State University rooted in values-based and positive youth development (PYD) principles. Using narrative inquiry, we conducted interviews and focus groups with 30 alumni ages …

4-H Program Staff Perceptions Of Including Youth With Disabilities, Brittney Muschetto, Amy Leman

Journal of Youth Development

This study’s focus is to examine 4-H youth development county program staff’s perceptions of the inclusion of youth with disabilities in the Illinois 4-H program. The majority of program staff identified positive perceptions about including youth with disabilities in 4-H. However, they also noted that there was a need for more staff training to adequately include youth with disabilities in 4-H programming. As more youth are being diagnosed with disabilities, 4-H must continue to improve its knowledge and skills to make 4-H inclusive to all youth.

A Hip-Hop-Based Workshop Cultivates Urban Underserved Youths’ Critical Consciousness Around Food Systems, Jacob Rowell, Hannah Scherer, Kim Niewolny, Anthony Kwame Harrison, Kendrick Spencer

Journal of Youth Development

Hip hop is social commentary and critique that highlights the complexity of issues within society, including systemic inequity in the food system, which disproportionately affects urban and African American populations. After-school and non-formal programs are innovative educational opportunities to engage youth in learning about and addressing local problems through culturally-relevant program design and enactment of critical pedagogy. To meaningfully connect middle-school-aged urban youth, their lived experiences, and inequities in the food system, we designed a hip-hop-based workshop and delivered it in an established afterschool program. In this qualitative case study, we explored participants’ critical consciousness related to the food system …

The Relationship Between Adverse Childhood Experiences, Protective And Compensatory Experiences, And Parenting Attitudes Among Fathers, Kylie Schmidt

Dissertations

Adverse childhood experiences (ACEs) are defined as potentially traumatic events that occur in childhood particularly between the ages of 0 and 17 years that negatively influence long-term health, relational functioning, and parenting practices (Centers for Disease Control and Prevention, 2026; Felitti et al., 1998; Merrick et al., 2019). Conversely, protective and compensatory experiences (PACEs) have emerged as protective factors that foster resilience and possibly buffer against the adverse outcomes of ACEs (Narayan et al., 2018). As the existing research has greatly focused on mothers, little is known about how men’s early life experiences shape their parenting attitudes, particularly during the …

Examining The Impact Of Social Support On Academic Self-Efficacy In Black Doctoral Students In Psychology, Asia A. Hall

Dissertations

This study examined the relationship between perceived social support and academic self-efficacy, or academic confidence, among Black doctoral students in psychology programs at predominantly White institutions (PWIs). Grounded in self-efficacy theory, the study was designed to explore whether perceived social support was associated with and predictive of students’ academic confidence. A quantitative, cross-sectional design was used, and data were collected using adapted versions of the Multidimensional Scale of Perceived Social Support (MSPSS) and the Academic Self-Efficacy (ASE) scale. The sample consisted of 60 Black doctoral students enrolled in psychology programs at PWIs across the United States. Descriptive statistics indicated the …

Alzheimer’S Disease And Related Dementias Risk Profiles And Health Literacy Among South Asian Seniors, Sandra A. Kennedy

Dissertations, Theses, and Capstone Projects

Alzheimer’s Disease and Related Dementias (ADRD) pose significant health challenges globally, with South Asian seniors in the United States facing elevated risks due to high rates of cardiovascular disease, diabetes, and limited health literacy. This study assessed dementia literacy and the prevalence of cardiovascular, psychosocial, and lifestyle risk factors among South Asian seniors in New York City, utilizing community-based participatory research (CBPR) principles in collaboration with India Home, a community-based organization. Fifty-six (N=56) South Asian seniors aged 55 and older (M = 69.05, SD = 6.36), primarily of Indian or Bangladeshi origin, participated in the study. Data collection involved a …

The Effects Of Chronic Nicotine Exposure On Dopamine-Mediated Reinforcement Learning And Striatal Neurotransmission, Srishti Bose

Dissertations, Theses, and Capstone Projects

Tobacco is one of the most widely used substances across the United States; tobacco consumption is linked with several diseases and is one of the leading causes of preventable death in the country. Nicotine is the active substrate found in tobacco products, acting as a stimulant, which reinforces continued use. The introduction of tobacco-free options such as e-cigarettes and oral pouches has driven an increase in nicotine exposure across the population, especially in young adults. Acute nicotine use induces neuroadaptations in the mesolimbic dopaminergic system, which mediates reinforcement learning and addiction, that potentiates reward-related neurotransmission. Furthermore, there are clinical studies …

A nature- and adventure-based youth development program designed to strengthen resilience, self-efficacy, nature-connectedness, and well-being among justice-involved youth was piloted in 2025 to address these challenges. Pilot findings indicated improvements in resilience, self-efficacy, hopefulness, and connectedness to nature.

The Ramifications Of Covid-19 On Young Adults With Ocd, Clare E. Mcintosh

Dissertations

The coronavirus disease of 2019 (COVID-19) pandemic was a profound event in modern history, contributing to significant disruptions on a societal and individual level. This period of time was marked by elevated uncertainty and fear among individuals. COVID-19 contributed to deterioration in not only physical health but also psychological well-being. One mental health condition frequently under-examined and saturated with misconceptions is obsessive-compulsive disorder. Obsessive-compulsive disorder is a condition characterized by the presence of obsessions and/or compulsions. Intolerance of uncertainty is a core component of the condition, and the pandemic was riddled with unpredictability. The purpose of this study was to …

Teaching Personal And Social Responsibility Through A Mountain Biking After-School Program, Kayla Marsh, Kelly L. Simonton, Victoria Shiver, Tristan Wallhead

Journal of Youth Development

The Teaching Personal and Social Responsibility (TPSR) model has been identified as an evidence-based structure that can support social-emotional learning (SEL) competencies in after-school settings. However, much of the research includes general physical fitness and skill activity-based programs, and not activities students identify with as meaningful in their lives. The current study targeted a mountain biking afterschool-program which has the potential to promote meaningful transfer of knowledge and skills. The purpose of this study was two-fold: (a) to explore adolescents’ beliefs and understandings of SEL skills in a mountain biking TPSR program and (b) to explore the perceptions of potential …

The Impact Of Stigma On The Mmpi-3 Scores Of An Indo-Caribbean Community Sample, Julia Persaud-Naipaul

Theses and Dissertations

Evaluation of personality and psychological disorders is accomplished through the use of psychometric measures. However, tests require interpretation of test responses using a normative criterion based on a particular population that may not fully consider the effect of cultural influences on an individual’s level of willingness to report psychological difficulties. For example, individuals in collectivistic cultures may not be as willing to self-report problems because mental illness is often perceived as a source of embarrassment and shame. One culturally unique population that has been overlooked in psychological assessment is the Indo-Caribbean population. Their specific cultural values, beliefs, attitudes, and practices …

Cognitive-Affective And Somatic Depressive Symptom Domains Related To Psychological Mechanisms And Sociodemographic Factors, Danielle B. Hazeltine

Dissertations, Theses, and Capstone Projects

Major depressive disorder is prevalent, chronic, and heterogeneous, including cognitive- affective (e.g., maladaptive beliefs or thinking patterns and sad mood) and somatic (e.g., fatigue, appetite, or sleep changes) symptom domains. While depression domains have been long theorized, research examining psychological mechanisms underlying this distinction is limited. Preliminary research suggests cognitive-affective symptoms relate more strongly to cognitive mechanisms (cognitive bias, perseverative thought), somatic symptoms relate more strongly to behavioral mechanisms (behavioral inhibition/activation), and gender, race, and ethnicity moderate these relationships. This study examined whether cognitive-affective and somatic symptom domains differentially relate to cognitive and behavioral mechanisms, and whether these relationships are …

Authoritarianism, Hostility And Threat: An Analysis Of American Political Podcasts Surrounding The 2024 Presidential Election, Noah D. Cohen

Dissertations, Theses, and Capstone Projects

Political rhetoric surrounding key events has seen sharp increases in emotionally affective speech, intergroup sentiment, and rhetoric unbecoming of democratic societies in recent years. Similarly, semi-democratic and ideologically driven speech has become increasingly normalized within an era of political polarization and hardline beliefs in modern media. Within this economy of outrage, sensational and largely unmoderated media formats, particularly podcasts, have become a mainstay of political information and discourse. This raises an important question: how does rhetoric surrounding political events construct intergroup sentiment and authoritarian rhetoric within political media, particularly American political podcasts? Further, given political podcasts’ growing social influence in …

Programs responded through holistic offerings that included tutoring, mentoring, trauma-informed practices, recreation, career readiness, …

Why Sports Participation Matters For Girls In Urban Core Public Schools, David Mcleod, Angela B. Pharris, David Crynes, Emmy Hufnagel, Eddie Wright, Sabrina Hynd, Tim Mclaughlin

Journal of Youth Development

Sports participation plays a critical role in supporting academic success, school engagement, and social-emotional well-being, particularly for girls in urban core public school settings. This study examines the relationship between athletic participation and academic outcomes, attendance, and social-emotional functioning in a large urban public school district during the post-COVID period. Findings indicate that student-athletes outperform non-athlete peers across multiple indicators, including grade point average, enrollment in advanced coursework, and school attendance. Female athletes, in particular, demonstrate stronger academic performance and more favorable social-emotional outcomes compared to female non-athletes. Despite these advantages, a pronounced decline in girls’ sports participation occurs between …

The Role Of Temperament In Criminal Trajectories: Development, Stability, And Predictive Power Across The Life Course, Joshua A. Lang

Dissertations, Theses, and Capstone Projects

Temperament, an individual's largely innate tendency to experience and regulate responses to their environment, has long been studied but was only recently introduced as a primary predictor of criminal behavior (DeLisi & Vaughn, 2014). While prior criminological theories have incorporated temperament-related constructs, such as negative affect (Agnew, 1992; Moffitt, 1993) and self-control (Gottfredson & Hirschi, 1990), no other theory has explicitly positioned temperament as the central factor in offending. DeLisi and Vaughn’s temperament-based theory of antisocial behavior posits that individuals with low effortful control and high negative emotionality—features of a difficult temperament—are more likely to engage in criminal behavior. Despite …

Parenthood And Re-Appraisal Of Childhood Maltreatment, Gayathri Cheran

Dissertations, Theses, and Capstone Projects

Background: Child maltreatment is associated with poorer physical and mental health outcomes across the lifespan.  Individuals’ appraisals of childhood maltreatment have important implications for these outcomes.  Appraisal is shaped by biological, psychological, and social-cultural factors, each of which undergoes change in parenthood.  Parenthood may prompt re-appraisal of childhood maltreatment in that being a parent evokes one’s experience of being parented.

Hypotheses: (1) Re-appraisal will be more likely in parents than non-parents.  In parents, re-appraisal will be more likely among: (2) primiparous parents, (3) parents with offspring of the same sex, and (4) parents who experienced maltreatment older in childhood (at …

When Protection Becomes Predation: Militarized Masculinity And Sexual Violence In Northeastern Nigeria, Tosin Osasona

Dignity: A Journal of Analysis of Exploitation and Violence

The study investigates the structural and situational drivers of conflict-related sexual violence (CRSV) perpetrated by state security actors in the context of Nigeria’s counterinsurgency campaigns in Borno State. Drawing on militarized masculinity and strain and deprivation theories, and using a qualitative, interpretive research design, the study argues that CRSV is not an isolated or episodic form of deviance by individual soldiers and security personnel but is embedded in routine military–civilian interactions. Advancing an interactionist explanation of CRSV in Nigeria’s Islamist counterinsurgency operations, the study demonstrates that the likelihood of sexual violence increases through the interaction of gendered institutional norms, operational …

Supporting English Language Learners: Evaluating Bilingual Education Policies In Boston Area High Schools, Valentina A. Tolentino

Undergraduate Theses and Capstone Projects

This study examines how the evolution of bilingual education policies and instruction has affected non-English speaking and bilingual high school students. Especially in Boston/Lynn Public School, bilingual and non-English speaking students are rapidly growing in population, yet questions still remain whether the existing educational policies adequately support their academic and emotional well -being. Using a demographic survey and interviews, I connected with high school graduates  ranging from 18 year olds to 22 years olds and asked questions to assess their language support, classroom experience, emotional well-being, and academic engagement. Analysis of the data demonstrates the influence that their bilingual education …

Coping Beyond Cancer: Exploring Fear Of Recurrence In Colorectal Cancer Survivors—A Pilot Investigation, Emily M. Su, Steve Paciorek, Erica L. Laipply, Anuja L. Sarode

HCA Healthcare Journal of Medicine

Background

Evidence is limited on the fear of cancer recurrence (FCR) among colorectal cancer (CRC) survivors in the US, especially regarding patterns and trends of post-recovery coping mechanisms. This pilot mixed-methods study quantified FCR, examined its associations with Brief COPE domains, and contextualized coping through qualitative analysis.

Methods

Twenty-three patients who successfully underwent CRC surgery were included in this pilot study. Fear of cancer recurrence was measured using the FCR Inventory (FCRI) Short Form, and coping strategies were assessed with the Brief Coping Orientation to Problems Experienced (COPE) survey. Descriptive statistics summarized participant characteristics, FCR, and COPE scores. Spearman correlation …

A Discursive Analysis Of Lesbian And Queer Experiences Of Unwanted Consensual Sex, Sarah E. Swanson

Graduate Doctoral Dissertations

This study drew on a critical discursive psychology (CDP) analytical approach to examine how lesbian and queer participants made sense of unwanted consensual sex (UCS).  The data analysis traced how UCS was constructed on three discursive levels: the construction of UCS across narratives, the interpretive repertoires mobilized (including sexual scripts), and the broader sociocultural discourses that shaped what elements of their experiences were intelligible. Therefore, I sought to understand both how participants drew on familiar heteronormative and queer ways of talking about sex and how various discursive resources shaped how they could construct themselves and others. Data for this research …

Home, Neighborhood, And Community Environments And Social Isolation In Later Life: Joint Associations And Their Moderation By Life-Course Socioeconomic Mobility, Jeein Law

Graduate Doctoral Dissertations

Social isolation is a major public health concern among older adults, yet less is known about how multilevel residential environments shape isolation among those aging in place. Guided by the Socio-Ecological Model, Person–Environment Fit, and a life-course perspective, this dissertation examined whether micro-level home hazards, meso-level neighborhood social cohesion and physical disorder, and macro-level census-tract structural conditions were associated with social isolation. It also examined whether life-course socioeconomic mobility moderated the associations between home and neighborhood environments and social isolation.

This dissertation used two nationally representative longitudinal studies of U.S. older adults. Aims 1 and 2 used the National Health …

Beyond Monolithic Narratives: The Interaction Of Ethnic-Racial Socialization And Resistance In Shaping Mental Health Among Black Immigrants In The U.S., Krystel Francis

Graduate Masters Theses

Black immigrants represent one of the fastest-growing segments of the U.S. Black population, yet their unique racialized and cultural experiences remain understudied within psychological research. This thesis examined how ethnic-racial socialization and resistance and empowerment against racism can influence how race-related stress was associated with psychological distress among Black immigrants in the United States. This study tested a moderated moderation model to determine whether ethnic-racial socialization and resistance and empowerment against racism, independently and jointly, buffered the adverse effects of race-related stress on psychological distress. Using data from a larger IRB-approved study on racism and mental health among people of …
