Sleep Challenges And Temperament Among Infants At Elevated Likelihood Of Autism Spectrum Disorder, Miranda Hope Foster

Theses and Dissertations

The current study used parent report in a prospective longitudinal design to examine the relationship between early sleep difficulties and temperament among infants with an older sibling diagnosed with ASD (EL-ASIB, n = 32), those born pre-term (EL-PT, n = 24) and those with no familial history of ASD (LL, n = 28) across the first year of life. At 3, 4, 6 and 12 months, caregivers completed the Short Form of the Infant Behavior Questionnaire-Revised (IBQ-R) (Putnam et al., 2014). To understand how sleep difficulties are related to temperament, a new scale of Sleep Challenges was created with items …

Gratitude Buffers The Effects Of Stressful Life Events On Early Adolescents’ Life Satisfaction And Externalizing Behaviors But Not Internalizing Behaviors, Mimi Scott Webb

Theses and Dissertations

Identifying psychological strengths that foster healthy development in youth has become a topic of exploration in the field of positive psychology (e.g., Suldo & Huebner, 2004; Valle et al., 2006). Gratitude is a promising trait-like characteristic with qualities indicative of a potential psychological strength that may serve as a protective factor for early adolescents in the face of stressful life events. This study utilized data from a sample of 1,880 middle school students from the Southeastern United States. Hierarchical regression analyses investigated gratitude’s role as a moderator in the relationship between stressful life events and adolescent well-being. Specifically, gratitude’s ability …

An Intersectional Lens To Covid-19: Promoting Youth Well-Being In The Midst Of Social-Political Stressors, Magdalena S. Moskal

Theses and Dissertations

Guided by interpretative phenomenological methodology and intersectionality theory, this thesis aims to uncover the mental health experiences of youth surrounding the COVID-19 pandemic. This study also seeks to situate these experiences with the subsequent stressors that young people face in the current social-political context (e.g., witnessing trauma in the media, uprisings to address racism and the resulting backlash, rhetoric of the 2020 presidential election). Furthermore, this thesis aims to give insight and voice how intersectionality shapes the COVID-19-related experiences of youth in South Carolina. Data was collected through semi-structured interviews with 23 participants aged 16-21 years old in South Carolina. …

Experiences Of Stigma, Social Support, And Anxiety In People Living With Hiv In South Carolina, Sarah J. Miller

Theses and Dissertations

People living with HIV (PLHIV) experience numerous psychosocial stressors, including HIV-related stigma and heightened prevalence of mental health disorders such as depression, substance use disorders, and anxiety. However, limited research has investigated predictors of anxiety within this population. This study aimed to explore the relationship between HIV-related stigma and anxiety symptoms among PLHIV in South Carolina (SC) and to examine the role of social support as a mediator for this relationship. A total of 402 PLHIV receiving HIV care at large immunology center in SC completed a paper and pencil survey, reporting sociodemographic variables, as well as experiences of HIV-related …

Predicting Therapists’ Intentions To Use An Innovation: The Role Of Innovation-Specific, Individual, And Organizational Factors, Jonathan KuʻUhoaepilipono Ahuna

Theses and Dissertations

Understanding factors that contribute to an individual’s decision to use an innovation can increase the public health impact of innovations in children’s mental health services. Objective. This study examined whether and to what extent therapists’ innovation-specific judgements (e.g., innovation is easy to use, socially desirable) were associated with intentions to use an innovation using constructs from one of the most robust theories of innovation use–the Unified Theory of Acceptance and Use of Technology (UTAUT). Method. Two aims were addressed using data collected from 95 therapists and 28 supervisors who participated in a multi-site cluster randomized trial. Therapists used either a …

Belonging In Context: An Exploration Of Sense Of Belonging Among College Students, Ladonna L. Gleason

Theses and Dissertations

Feeling a sense of belonging is essential to human health and functioning and has been well documented in the literature. However, questions of context remain. Research in belonging has focused on social aspects of belonging, leaving broader contextual frames unexplored. There has been little work in identifying and differentiating the contexts in which belonging is experienced or in developing an understanding of how the experience of belonging differs across contexts. Current belonging theory lacks this important contextual perspective that could inform the ways in which belonging is constructed and reconstructed through disruption. With the advent of the COVID-19 pandemic, new …

Integrated Behavioral Health And Primary Care: Refining A Determinant Framework, Ariel Michelle Domlyn

Theses and Dissertations

The integration of behavioral health and primary care is a best practice to improve patient outcomes and achieve health equity. However, the process of integrating is opaque, requiring organizational change and sometimes a complete system overhaul. Implementation science offers useful ideas for helping healthcare organizations to implement care. This field has identified potential environmental conditions and determinants of successful implementation; however, much is still unknown about how these factors may be relevant for organizations seeking to integrate care. To address the limited existing knowledge in this area, this dissertation gathers practice-based evidence using exploratory methods. Results are translated into an …

An Evaluation Of A School Mental Health Program For Underserved Youth In Rural South Carolina, Tristan Collier

Theses and Dissertations

School, community, and youth-serving system partnerships can support implementing comprehensive school mental health (SMH) systems including services beyond direct therapy for students (i.e., multiple tiers of support). Utilizing a comprehensive approach to SMH allows clinicians to form stronger relationships with administrators, school staff, and most importantly, students who may need services. This comprehensive approach to SMH includes incorporating the SMH clinician into the culture and daily activities of the schools (e.g., helping direct students in the bus line), to increase the visibility of the clinician and services available as well as provide opportunities for direct outreach to students. One such …

Cognitive Consequences Of Covid-19 Infection And Quarantine-Induced Social Isolation: Hope For The Young And Mildly Infected, Kristin Nickole Kirchner

Theses and Dissertations

Coronavirus disease 2019 (COVID-19) has infected over 539 million individuals worldwide, and initial research supports the possibility that COVID-19 may damage the central nervous system either directly or indirectly. Neurological signs and noted cognitive deficits observed in even mildly infected patients are a cause for concern for those infected by COVID-19; the effect of social isolation on the central nervous system is also of interest. The present study sought to determine the extent of these potential cognitive deficits in a young and mildly infected sample of college students. Participants completed an extensive survey assessing their experience with COVID-19 and any …

The Moderating Impact Of Gender And Friendship Quality On The Effects Of Interparental Conflict On Adolescent Internalizing Problems, Jessica Dandan

Theses and Dissertations

In response to escalating concerns about the increasing incidence of adolescent internalizing disorders, several mechanisms have been investigated to understand their etiology. Though genetic predisposition contributes to the risk for psychopathology, its interaction with environmental stressors such as interparental conflict appears to further increase this risk. Girls are more susceptible to stressors and twice as likely as boys to develop internalizing problems. However, friendship quality may buffer some of the adverse effects incurred from exposure to interparental conflict. A recent review of proposed mechanisms through which conflict is associated with youth psychopathology pinpointed the need for further adolescent-focused research including …

Race, Racial Matching, And Cultural Understanding As Predictors Of Treatment Engagement In Youth Mental Health Services, Wendy Chu

Theses and Dissertations

Racially marginalized youth experience barriers that impact their ability to maximally benefit from mental health services; thus, efforts to identify strategies that support youth treatment engagement may address mental health and treatment disparities. This study examined the role of youth race, youth-therapist racial matching, and youthreported therapist cultural understanding on youth’s early treatment engagement in mental health services. The youth sample (n = 1159; M_age = 13.8 years, SD = 2.9; 52.1% female) comprised of 778 (67.1%) Latinx, 221 (19.1%) African American, 139 (12.0%) White, and 21 (1.8%) Asian American clients. The therapist sample (n = 126; Mage …

Investigating The Role Of Stressful Life Events And Emotion Regulation As Potential Antecedents Of Gratitude In Early Adolescents, Olivia Schmitke

Theses and Dissertations

ABSTRACTThe construct of gratitude has gained interest over the last decade along with the rise of positive psychology. Gratitude’s significant relations with psychological and psychosocial factors have been shown in prior research, although support for such relations in children and adolescents exists, to date the literature is more robust around adults. Additionally, presumed antecedents of individual differences in gratitude have been acknowledged. The present study included a sample of 1872 middle school students and aimed to build on previous work to explore the influence of emotion regulation (i.e., cognitive reappraisal and expressive suppression) in the development of gratitude among youth …

The Relation Between Adhd Symptoms And Alcohol And Marijuana Use Outcomes Among College Students: The Mediating Role Of Experiential Avoidance, William Joshua Bradley

Theses and Dissertations

Individuals with attention-deficit/hyperactivity disorder (ADHD) are at significantly greater risk for alcohol and marijuana misuse and abuse compared to their peers. College students with ADHD may be particularly vulnerable to problematic alcohol and marijuana use, given the widespread use and abuse of these substances by college students generally and liability associated with ADHD specifically. Experiential avoidance, or avoidance of unwanted thoughts, feelings, and other internal experiences, is positively associated with ADHD symptoms and substance use problems. However, it is unclear what role experiential avoidance plays in the relation between ADHD and alcohol and marijuana use. This study examined whether experiential …

S-Equol: A Novel Therapeutic For Hiv-1 Induced Gut Dysbiosis, Mason T. Rodriguez

Theses and Dissertations

HIV-1 infection affects approximately 38 million people around the world. The advent of cART has greatly improved the quality of life of infected individuals; however, roughly 50% of these individuals will still experience HIV-1 associated neurocognitive disorders (HAND). Additionally, the gut microbiome has been reported to be dysbiotic in HIV-1 infected individuals, regardless of adherence to cART. Current research has pointed to the gut-brain-microbiota axis as a potential target to treat both cognitive deficits and microbial changes. The present study investigated S-equol (SE) as a potential therapeutic for HAND by modulating the gut microbiome. The study included 21 HIV-1 Tg …

Trajectories And Psychiatric Consequences Of Inhibitory Control In Young Males With Fragile X Syndrome, Erin Hunt

Theses and Dissertations

Inhibitory control (IC), the ability to suppress inappropriate responses, emerges late in the first year of life and improves across typical development, concurrent with brain maturation. The development of IC is critical to various social-emotional and behavioral functions, with IC deficits being linked to numerous psychiatric conditions, including attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Fragile X syndrome (FXS) is a single-gene disorder characterized by IC deficits, and elevated rates of ADHD and ASD, making it a useful model for understanding the early development and consequences of IC. In this longitudinal study, we characterized IC trajectories across multiple time …

Moderating Effects Of Parental Feeding Practices And Emotional Eating On Dietary Intake Among Overweight African American Adolescents, Mary Quattlebaum

Theses and Dissertations

This study examined the effects of parental feeding practices and adolescent emotional eating (EE) on dietary outcomes among overweight African American adolescents. Based on Family Systems Theory, it was hypothesized that parental feeding practices, such as parental monitoring and responsibility, would buffer the effects of EE on poor dietary quality, whereas practices such as concern about a child’s weight, restriction, and pressure-to-eat would exacerbate this relationship. Adolescents (N = 127; Mage = 12.83 ۫.74; MBMI % = 96.61 ± 4.14) provided baseline data from the Families Improving Together (FIT) for a Weight Loss trial and an ancillary study. Dietary outcomes …

Impact Of Number Of Alternatives And Spatial Arrangement On Decoy Effects, Jacob M. Stanley

Theses and Dissertations

The way in which people make decisions is largely guided by the context of the choice set. Choice sets that contain decoy alternatives can result in context effects that violate rational principles of decision making. Most studies on contextual choice manipulate preference among two alternatives in the context of a decoy using three option choice sets. However, many real-world decisions are made among choice sets with many more than three alternatives, such as in online shopping. We tested for attraction and compromise decoy effects in choice sets with varying numbers of alternatives by using a within-subjects preferential grocery shopping task. …

Associations Between Child Characteristics And Maternal Mental Health In Families Of Children With Autism, Fragile X Syndrome, And Autism Associated With Fragile X Syndrome, Tiffany Nicole Worley

Theses and Dissertations

The present study examined the association between various child characteristics and maternal mental health concerns in three high-risk groups of mothers ± those of children with non-syndromic autism spectrum disorder (NSASD), mothers of children with fragile X syndrome (FXS), and mothers of children with fragile X syndrome and autism (FXS+ASD). Research has shown that mothers of children with NSASD and FXS are thought to share a degree of genetic vulnerability to mental health concerns it is key to examine the various other factors that may contribute to difficulties within the family system and maternal stress, depression, and anxiety.

Using Item-Response Analysis To Evaluate The Task-Demands Of A Pictural-Response Based Test Of Word Reading, Michael Eason

Theses and Dissertations

While some children’s reading difficulties are a consequence of socio-economic factors and inadequate instruction, other children have extreme difficulties learning to read despite having adequate educational opportunity and adequate levels of intelligence. These children are classified under the Individuals with Disabilities Education Act (IDEA) as having a learning disability specific to reading (SLD-R). The identification of children with SLD-R is costly on time, personnel, and other school resources, and due to an insufficient number of resources generally available to schools, the methods implemented for identifying children are alarmingly inconsistent. The aim of the current study is to investigate the task …

Testing Models Of Context-Dependent Outcome Encoding In Reinforcement Learning, William M. Hayes Iv

Theses and Dissertations

Previous studies of reinforcement learning (RL) have established that choice outcomes are encoded in a context-dependent fashion. Several computational models have been proposed to explain context-dependent encoding, including reference point centering and range adaptation models. The former assumes that outcomes are centered around a running estimate of the average reward in each choice context, while the latter assumes that outcomes are compared to the minimum reward and then scaled by an estimate of the range of outcomes in each choice context. However, there are other computational mechanisms that can explain context dependence in RL. In the present study, a frequency …
