Social Cognition As A Mediator Between Neurocognition And Functional Outcome In Early Course Schizophrenia, Anju Kotwani, Jessica A. Wojtalik, Douglas D. Gunzler, Wilson J. Brown, Rochanne L. Honarvar, Martha Sajatovic

Faculty Scholarship

Social cognition is an established mediator between neurocognition and functional outcome in schizophrenia, but there is limited evidence for this model specifically in the early course, which is a critical window for intervention to reduce long-term disability. This study aimed to test the social cognition mediator model in the early course of schizophrenia and identify social cognitive subdomains that may have stronger indirect effects on the relationship between neurocognition and functional outcome. This secondary analysis utilized baseline cognitive and functional outcome data from a cognitive remediation trial for outpatients with early course schizophrenia (N = 102). A path analysis approach …

Participants expressed concerns about the limited availability of appropriate assessments for Deaf and Hard of Hearing (DHH) students and challenges in adapting existing assessment tools. The findings highlight a need for enhanced assessment training in teacher …

Associations Between Parental Audism/Linguisticism And Deaf Individuals' Well-Being: Mediation By Interpersonal Needs And Relationship Quality, Dilan H. Arreguin, Crystal D. Oberle

JADARA

This study investigated whether audism and linguisticism from the parents of physically deaf or culturally Deaf individuals—that is, parents’ expectation of their child to communicate within audio-normative standards rather than use sign language—is related to poor mental health of the child. It also investigated whether these relationships are accounted for by interpersonal needs or child-parent relationship quality. For this study, 104 D/deaf adults completed a survey with measures of parental audism and linguisticism, depression, anxiety, thwarted belongingness, perceived burdensomeness, parental closeness, and parental conflict. Parental audism and linguisticism positively correlated with depression and anxiety, and these relationships were mediated by …

School Leaders’ Perceptions Of Restorative Practices On Student Behavior, Jennifer Mary Herold Fontenot

Electronic Theses and Dissertations

United States public schools turned to a zero-tolerance approach to school discipline with hopes of improving school safety and climate in the 1990s. Administrators dispensed consequences such as suspension and expulsion without considering the whole student, regardless of the student’s conditions, motivations, or background. Many schools today focus on punitive measures rather than a holistic approach that considers the root causes of behavior, such as socioeconomic factors, mental health issues, or the student’s home life. Such actions can lead to disproportionately harsh punishments for marginalized students, particularly those from low-income backgrounds or communities of color, exacerbating existing inequalities. Thus, the …

Nursing Education For Type 2 Diabetes And Nutrition Using Individual 1:1 Sessions In Rural Health Care, Meagan F. Wheat

Electronic Theses and Dissertations

What if proper nutrition were a nonpharmacological treatment for health problems? Nutrition is an important key to overall wellness. When patients receive the right education, they not only get the proper nutrition in their diet but also can manage their diabetes and live a better quality of life. In rural U.S. health areas, lack of access to nutrition is a barrier to patient care. Rural areas are at an even higher risk due to a lack of resources for good nutrition. One-to-one nutrition education with a nurse specialized in diabetes helps teach patients at a learning level they will comprehend. …

Differences In Peer Social Connections Between Traditional And Online Nurse Residency Programs, Tatum Leonard

Electronic Theses and Dissertations

The anticipated retirement of baby boomer nurses by 2030 will intensify the global nursing shortage, a crisis that demands innovative strategies for onboarding and retaining new graduate nurses. Nurse residency programs (NRPs) are designed to ease the transition from student to practicing nurse, reduce turnover, and foster professional resilience. Amid the COVID-19 pandemic, many NRPs rapidly transitioned from traditional, in-person seminars to synchronous, online formats. This study explored differences in peer social connections between traditional and online NRPs, focusing on three constructs: sense of community, collaborative learning, and peer social support. Using a quasi-experimental, mixed methods approach, this secondary data …

Endocannabinoids Mediate Racial/Ethnic Discrimination Prediction Of Posttraumatic Stress Disorder Symptoms Moderated By Resting-State Functional Connectivity In Black And African American Individuals, Emily A. Albertina, Lucas Torres, Garrett Sauber, Cecilia J. Hillard, Jacklynn M. Fitzgerald, Terri A. Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background

Individuals from marginalized ethnoracial groups face higher risk for posttraumatic stress disorder (PTSD) symptoms, exacerbated by experiencing racial/ethnic discrimination. Previous work separately explored the endocannabinoid (eCB) system and functional connectivity response to stress/trauma and suggested that experiences of chronic minority stress, such as racial discrimination, contribute to eCB tone and resting-state functional connectivity. We explored how circulating eCB tone, in conjunction with resting-state connectivity, contributes to increased risk for PTSD symptoms following trauma among individuals experiencing discrimination.

Methods

Black/African Americans (n = 74; mean age = 33.81 years) were recruited from a level 1 trauma center. Correlational and …

Barclay, R. Berniūnas, J. Contreras-Garduño, B. Costa-Neves, M.P. Grazioso, P. Elmas, P. Fedor, Li, Norman P., R. Fernández-Morales, L. Garcia-Marques, P. Giraldo-Perez, P. Gul, F. Habacht

Research Collection School of Social Sciences

Meaning-making systems underlie perceptions of the efficacy of threat-mitigating behaviors. Religion and science both offer threat mitigation, yet these meaning-making systems are often considered incompatible. Do such epistemological conflicts swamp the desire to employ diverse precautions against threats? Or do individuals—particularly individuals who are highly reactive to threats—hedge their bets by using multiple threat-mitigating practices despite their potential epistemological incompatibility? Complicating this question, perceptions of conflict between religion and science likely vary across cultures; likewise, pragmatic features of precautions prescribed by some religions make them incompatible with some scientifically-based precautions. The COVID-19 pandemic elicited diverse precautions thus providing an opportunity …

Public Support For And Reactive Behavior Toward Technological Risk Interventions: An Extension Of Secondary Risk Theory, Hye Kyung Kim, Rui Gu, Fiona Goh, Sonny Rosenthal, Shirley S. Ho

Research Collection College of Integrative Studies

Project Wolbachia is a dengue control initiative in Singapore. Guided by Secondary Risk Theory, this study examined how primary (dengue) and secondary (Wolbachia) threat and coping appraisals shape public support and reactive behavior toward the project. A nationally representative survey of 1,000 Singaporeans showed that support was positively linked to the perceived primary risk, the efficacy of the project and the government, while negatively related to the perceived secondary risk. Reactive behavior was positively associated with perceptions of both primary and secondary risk. Media attention and trust in the government indirectly influenced support and behavior moderated by knowledge.

Launching! To Adulthood, A Culturally Adapted Treatment Program For Military-Dependent Autistic Young Adults And Their Military Parents: A Pilot Study, Antonio F Pagán, Jordan Kenemore, Maj Mark Ahlenius, Linda Hernandez, Stephen Armstrong, Katherine A Loveland, Ron Acierno

Faculty, Staff and Student Publications

Introduction: Military-dependent young adults (17-25 years old) with autism spectrum disorder (ASD) face significant barriers to accessing services during their transition to adulthood. Frequent relocations, disrupted care, and limited ASD-tailored interventions exacerbate the challenges for these families, with many young adults experiencing a "service cliff" as they age out of pediatric care and school-based services. Addressing these gaps is critical, particularly given the rising mental health challenges and executive dysfunction in this population. This study evaluates the preliminary efficacy of an adapted telehealth intervention, the Military-Launching! program, designed to support young adults with ASD and their military families.
