Building Capacity Through The Use Of A Strategic Prevention Framework System In Communities, Duncan Meyers

Theses and Dissertations

The Strategic Prevention Framework (SPF) is a planning and implementation model that mobilizes communities to collaborate on developing and implementing an evidence-based prevention system. This model follows a structured five-step process with two cross-cutting elements (cultural competence and sustainability) that emphasizes building capacity of coalitions to strategically plan, implement, and sustain evidence-based prevention services to reduce adolescent substance use. This study utilized a repeated cross-sectional design. Participating youth were in grades 6, 8, 10, and 12 and lived in one of 27 counties in a Southeastern state that was funded through the Center for Substance Abuse Prevention’s SPF State Incentive …

The Impact Of Sports Dropout On Adolescent Functioning, Brittany Skiles Cook

Theses and Dissertations

Sports is the most commonly participated in extracurricular activity during adolescence. Aligned with the Positive Youth Development theoretical framework, previous research has shown that sports participation offers youth a context rich in resources found to promote positive adjustment into adulthood. However, around one third of the youth participating in sports drop out each year, and little research has examined the impact of sports dropout on indicators of youth adjustment. This study examines the relation between sports dropout and academic achievement, self-esteem, depression, perceived school climate, perceived support from adults in school, and alcohol use. The moderating effect of sports engagement …

Investigating Construct Validity Of The Cyber--Peer Experiences Questionnaire, Kendall Moore

Theses and Dissertations

With electronic technology becoming increasingly important in all aspects of modern life, traditional forms of relating with others have crossed into the cyber realm. Within that context, both positive and negative aspects of relational behavior have advanced in ways still largely underexplored in the research literature. One such area, termed “cyberaggression,” has recently gained momentum as a research focus. Given the numerous mental health sequelae from being involved in cyberaggression, such as anxiety, depression, and suicidal ideation, there is a clear and compelling need for more research in this area. To date, however, there remains little consensus on the conceptualization …

Do Discipline Style And Parenting Self-Efficacy Interact To Predict Observed Child Behavior? Outcomes From A Representative Sample Of Mothers With Young Chilren, Emily Noel Neger

Theses and Dissertations

Both parenting style and parents’ sense of their own parenting self-efficacy (PSE) have been found to predict child behavior outcomes in young children. Parents who engage in lax or overreactive parenting practices or who lack confidence in their parenting abilities are more likely to have children who display disruptive and noncompliant behavior. Until now, very little research has examined whether an interaction exits between these two constructs in predicting child behavior outcomes. The current study looked to fill this gap and assess whether a significant moderation relationship exists between parents’ parenting style and PSE in predicting observed child behavior. A …

Hiv-1 And Cocaine: Motivation And Synaptic Function, Sarah J. Bertrand

Theses and Dissertations

Molecular and behavioral assays were used to examine the effects of HIV-1 on synaptodendritic integrity, motivated behavior and the therapeutic potential of natural isoflavones in ameliorating both synaptodendritic injury in vitro and changes in motivation in vivo. The overarching hypothesis of the present dissertation is twofold: 1. HIV-1 causes a decrease in motivation for sucrose and cocaine and the change in motivational state is driven by compromised synaptic integrity as evaluated by F-actin and DAT function and, 2. Treatment with phytoestrogens will prevent synaptodendritic damage, normalize the internal motivational state of the HIV-1 Tg rat for sucrose and cocaine, and …

Behavioral And Heart-Defined Attention In Infants At High Genetic Risk For Autism, Bridgette L. Tonnsen

Theses and Dissertations

Characterizing early predictors of autism facilitates earlier identification, diagnosis and treatment. Although aberrant visual attention is one of the earliest identified predictors of autism and may play an integral role in developmental cascades that contribute to associated impairments, the emergence of atypical attention in infancy is poorly understood. The present dissertation includes three related manuscripts examining early patterns of visual attention in two infant samples at elevated risk for autism: infant siblings of children with autism (ASIBs) and infants with fragile X syndrome (FXS). Together, these manuscripts identify patterns of abnormal heart defined attention among ASIBs (Study 1), investigate the …

Working Memory In Children With Neurocognitive Effects From Sickle Cell Disease: Contributions Of The Central Executive And Processing Efficiency, Kelsey Erin Smith

Theses and Dissertations

Children with sickle cell disease (SCD) are at risk for neurocognitive impairment due to disease effects including stroke, sleep disordered breathing, anemia-induced hypoxia, and small vessel occlusion. In particular, problems in working memory are an area of concern due to the importance of this construct in determining intelligence and academic functioning. According to Baddely’s model, working memory is composed of verbal and spatial working memory, but it is unclear whether one aspect of working memory is more impacted than another in children with SCD. In addition, little is known about the role of two key components in SCD-related working memory …

The Relationship Between Religiousness And Intimate Partner Violence Risk And Protective Factors, Peter Warren

Theses and Dissertations

This paper proposes an integrated model illustrating the mechanisms by which religiousness may serve to influence individual beliefs regarding intimate partner violence (IPV) and the potential for subsequent abusive behavior. Intimate partner violence is a serious public health issue in the US, affecting over 25% of women at some point in their lives (CDC, 2010; Tjaden & Thoennes, 2000). Religion is a near ubiquitous aspect of American culture, with over 80% of Americans reporting some kind of belief in a higher power (Gallup, 2008. Overall, the literature shows that religiousness typically serves as a protective factor against IPV, but digging …

Sleep Extension And Stable Sleep Schedules In Older Adults, Alexandria M. Reynolds

Theses and Dissertations

There is consistent evidence demonstrating a “U-shaped” association between sleep duration and mortality, as well as several morbidities, such as increased systemic inflammation, decreased cognitive performance, and mood disturbances. Much of the information on long sleep is epidemiological in nature. The present study examined the associations between sleep duration and extension on mood, inflammation, and cognition. Ten (50-79 y) healthy adults who report sleeping 6-8 h were assessed on cognitive, emotional, and inflammatory measures in a cross-over design. Following a baseline week, participants were randomized to one of two three-week treatments: (1) a control treatment of habitual time in bed; …

The Syntax-Space Effect, Timothy W. Boiteau

Theses and Dissertations

Previous research has linked the concept of number and other ordinal series to space via a spatially-oriented number line. Other researchers have shown that language as well may have an underlying spatial representation, though this seems to be tied to visual scene recognition and production and is potentially an idiosyncratic effect of a limited set of concrete verbs. In this dissertation, employing a novel method that measures the underlying spatial biases of actors in transitive sentences, I show that findings from previous studies showing a relationship between transitivity and space reflect an interaction between word order in the sentence, order …

Representation Of Affect From Fmri Data As A Function Of Stimulus Modality And Judgment Task, Jongwan Kim

Theses and Dissertations

The theory of core affect posits that the neural system processes affective aspects of stimuli encountered by the organism quickly and automatically, resulting in a unified affective state described along the dimensions of valence and arousal. Core affect theory posits two functional subsystems that guide affective processing: a sensory integration and a visceramotor network. The proposed study investigates how the representation of affective dimensions depends on sensory modality, features of the task, and brain regions. A series of behavioral studies was run to develop an experimental stimulus set of silent videos and musical clips that met requirements of equating valence …

Randomized Control Study Of Neurofeedback With College Students With Adhd, Alycia M. Roberts

Theses and Dissertations

Neurodevelopmental disorders such as ADHD represent a major national problem. There are increasing numbers of students in schools requiring special education services as a result of ADHD, and each of these students costs the U.S. education system approximately $5,000 per year (Robb et al., 2011). There are additional societal costs associated with the disorder, and ADHD can be debilitating for individuals with the disorder and their families (i.e., Barkley & Murphy, 2010; Ginsberg, et al., 2013). The most common treatments are stimulant medication and behavioral training (i.e., Pelham & Fabiano, 2008), but recently neurofeedback (EEG biofeedback) has been receiving a …

Testing An Ecological Model Of Parent Involvement In Head Start: A Replication Study, Rebecca C. Horwitz

Theses and Dissertations

Parent involvement has been understood to elicit positive outcomes for school-age children, especially minority children and children from low socioeconomic families. Understanding the process by which parents engage in their child’s education may provide school staff with tools to develop interventions to increase parent involvement.

This investigation replicates a study that tested an ecological model of parent involvement in two Head Start programs (Waanders, 2002). Participants in the current study were 213 parents and/or caregivers of children who attended three Head Start programs in South Carolina. Two of the programs were located in a medium-sized city, while the third was …

The Role Of Effortful Control And Cortisol In The Emergence Of Adhd, Asd, And Anxiety In Boys With Fxs, Marissa L. Robinson

Theses and Dissertations

ADHD, ASD, and anxiety are three of the most common co-occurring disorders in children with FXS leading to increased social, academic, and behavioral difficulties (Bailey, Raspa, Olmsted, & Holiday, 2008). Early identification and treatment of these co-occurring mental health disorders is essential to promote optimal outcomes; therefore, the study of early precursors and underlying mechanisms of these disorders within a developmental framework is warranted. The current dissertation includes two sequential and related studies investigating impaired effortful control as a precursor and HPA axis dysfunction (measured through salivary cortisol) as an underlying mechanism to the emergence of ADHD, ASD, and anxiety …

The Association Of Gender, Age, And Coping With Internalizing Symptoms In Youth With Sickle Cell Disease, Laura Reinman

Theses and Dissertations

Youth with sickle cell disease (SCD) are at an elevated risk for having internalizing symptoms. Prior studies have suggested unique age by gender patterns of internalizing symptoms may be present in this population, however this pattern has not been thoroughly examined and the mechanisms underlying this pattern are not known. We examined rates of depression and anxiety symptoms between males and females with SCD across childhood and into adolescence in a cross-sectional design. We also considered the potential role of coping styles and health related locus of control for SCD morbidity that could account for age or gender patterns for …

Low-Dose Stimulant Treatment During Periadolescence In A Fasd Model: Interactions Among The Catecholamines, Victoria Macht

Theses and Dissertations

One of the most common of deficits observed in Fetal Alcohol Spectrum Disorders (FASD) is difficulties with attention. Because attention deficits are commonly treated with stimulants, the impact of d-amphetamine (AMPH) treatment during the juvenile period in an animal model of FASD was examined. A dose-response study first assessed the appropriate dose of AMPH to use. In the dose-response study, therapeutic doses of 0.5, 1.0, and 2.0 mg/kg/day of AMPH were chronically administered to female rats between postnatal days (PD) 26-40. Rats were subjected to an open field test on the first and last day of treatment. The dose of …

Antecedents Of Adolescents' Hope: Personality, Parental Attachment, And Stressful Life Events, Kristin L. Otis

Theses and Dissertations

In the past decade, psychology has concentrated on the importance of identifying psychological qualities in individuals that indicate positive mental health and flourishing. Hope has been proposed to be one of these qualities (Day, Hanson, Maltby, Proctor, & Wood, 2010; Marques, & Lopez, 2014). This study examined the relations among parental attachment, stressful life events, personality variables, and hope in a sample of 647 middle school students from one middle school in a Southeastern US state. The results showed statistically significant correlations between hope and all four predictor variables as well as students’ grade levels and socioeconomic status (SES). The …

Using Geographical Information Systems To Investigate Access To School Mental Heath Services, Heather L. Mcdaniel

Theses and Dissertations

Many youth present emotional or behavioral difficulties at levels that necessitate mental health services, yet few receive these needed services. However, school mental health services are thought to improve access to mental health services for youth and families over and above traditional community mental health centers. The purpose of the current study was to expand on existing research by examining community-level and geographic predictors of the utilization of school mental health or community mental health services. Within the context of a large, federally funded trial, I examined how community rurality, ethnic/racial makeup and drive time predicted the use of either …

Mindfulness And Cognitive Aging, Elise J. Herndon

Theses and Dissertations

Mindfulness meditation involves the cultivation of a focused, pre-conceptual consciousness that enables increased present-centered awareness of internal states, cognitive processes, and external stimuli (Mikulas, 2011; Kornfield, 2010). Studies suggest that mindfulness practice affects the brain structures and cognitive processes related to fluid intelligence, and may affect fluid intelligence itself among highly experienced practitioners (e.g., Gard, Taquet, et al., 2014; Lazar et al., 2005; Ritskes et al., 2003). Fluid intelligence includes higher-order reasoning and problem-solving abilities that are independent of cultural and environmental influences. These abilities peak in young adulthood, then begin to decay (Cattell, 1987; Goldberg, 2005).

The current study …

Reliability Of Subjective Well-Being Measures In Middle School Students, Hannah Reckhart

Theses and Dissertations

A rise in the emphasis of positive aspects of functioning has led to increased attention paid to the field of positive psychology. Encompassed in this field is the recognition of subjective well-being (SWB) as an important factor in developing a holistic understanding of students. Established significant positive relations between SWB and academic engagement suggest that incorporating positive psychology variables, such as SWB, into assessment may be a useful and feasible tool to develop a comprehensive understanding of student strengths and difficulties. In this study, we investigated the reliability of three promising SWB measures for use within the school context. Results …

What Do We Know About Technical Assistance? Enhancing The Science And Practice Of Technical Assistance Via A Research Synthesis, Jason S. Katz

Theses and Dissertations

Introduction. Each year billions of dollars are spent on providing technical assistance (TA) to build the capacity of host settings (e.g., organizations, communities) to implement innovations, but there is little consensus (or even discussion) about: what the essential features of TA are, how to provide TA with quality, and how a quality-based accountability perspective can help us to enhance the science and practice of TA. To begin to address these needs, a research synthesis methodology was used for conducting a content analysis of the current evidence base for TA using three frames: (1) applying a conceptual and operational model (Getting …

A Comparison Of The Factor Structure Of The Short Form Liberal Feminist Attitude And Ideology Scale (Lfais) For Women And Men In A University Survey, V. Diane Woodbrown

Theses and Dissertations

The current study compares the factor structure of the short form Liberal Feminist Attitude and Ideology Scale (LFAIS; Morgan, 1996) for males and females in a University survey. We first provide a discussion of feminism, a brief narrative review summarizing previous and co-existing measures of the construct “feminist attitudes” for males and females, and then conduct confirmatory factor analyses (CFA) and exploratory structural equation modeling (ESEM) to test Morgan’s own theory that there may exist a single general factor underlying the Liberal Feminist Attitudes Ideology Scale for males and for females, and that the latent construct/s underlying this scale are …

Anxiety And Autism Symptomology On Social Skills In Young Boys With Fragile X Syndrome, Debra L. Reisinger

Theses and Dissertations

Children with fragile X syndrome (FXS) are at high risk for developing several comorbid disorders, including autism spectrum disorder (ASD) and anxiety, that can substantially impart their social skills. However, to date, there are no studies that examine complex social skills within boys with FXS and the effects of emerging autism and anxiety symptoms on the development of their social skills. The current study examines social skills at the composite and subdomain level in young boys with FXS in contrast to typically developing (TD) boys and in relation to age, adaptive behavior, anxiety symptoms and autism symptomology. The study consisted …

A Longitudinal Examination Of The Mediating Role Of Social Problem Solving Between Parental Attachment And Early Adolescents’ Life Satisfaction, Xu Jiang

Theses and Dissertations

Both attachment theory and empirical evidence indicate that the quality of parental attachment profoundly influences many different aspects of adolescent life. However, one area that has been somewhat neglected in the literature is the discovery of the psychosocial mechanisms that account for the link between parental attachment and important adolescent developmental outcomes, such as social problem solving (D’Zurilla & Goldfried, 1971) and life satisfaction (LS: Diener, 1994). Driven by the conceptual framework of development of LS proposed by Evans (1994), Attachment Theory and Social Problem Solving Theory, a mediation model was hypothesized to explore the link between parental attachment and …

Pathways Thinking As A Mediator Between Positive Emotions And General Life Satisfaction In Middle School Students, Kathleen B. Franke

Theses and Dissertations

Informed by the broaden-and-build theory of positive emotions, we tested a model of the origins of life satisfaction with a sample of 567 middle school students from the Southeastern United States. The pathways thinking domain of hope was proposed to mediate the relation between positive emotions and general life satisfaction at a single time point, as well as over one year. At Time 1, pathways thinking was a significant mediator of positive emotions and life satisfaction. In the longitudinal model, pathways thinking did not significantly mediate this relation between positive emotions and later life satisfaction. These findings have implications for …

The Role Of Self-Efficacy In Mediating The Effect Of Physical Activity On Adolescent Depression, Nevelyn N. Trumpeter

Theses and Dissertations

Depression is a common psychiatric problem experienced in adolescence with nearly a quarter of all adolescents experiencing a major depressive episode before adulthood. Previous evidence indicates that physical activity (PA) is a known protective factor for depressive symptoms and major depressive disorder in adolescents and that PA self-efficacy (i.e., self-confidence) improves self-esteem, which in turn reduces depressive symptoms. Furthermore, PA self-efficacy may be more protective against depression for individuals who value or consider PA to be highly important. The proposed study aimed to determine the cross-sectional and longitudinal PA-depressive symptoms relation in adolescents. The study was designed specifically to test …

Beyond Grades: The Impact Of Race And Academic Disidentification On Social Functioning And Academic Outcomes Among At-Risk High School Students, Brian K. Colar

Theses and Dissertations

An extant literature has supported the notion that black students perform poorly in comparison to white students on frequently used indicators of academic functioning, known as the academic gap between races. Although previous studies have identified this academic inequity between White and Black high school students, there is a dearth of literature examining the context and processes which may contribute to this gap. The current study further examines this educational disparity by evaluating the role of students’ social functioning, the impact of race, and academic outcomes among at-risk high school students. Although analytical evidence reports a positive correlation between social …

Group Social Skills Interventions For Children With Aspergers: The Effects Of Parent-Guided Social Skills Software, Ryan M. Kelly

Theses and Dissertations

Asperger’s syndrome (AS) has recently become controversial as a unique pervasive developmental disorder. Although it is apparently different than low-functioning autism, it has been deemed too similar to high-functioning autism (HFA) to be considered a distinct diagnosis in the DSM-5 classification system. However, despite the removal of AS from the DSM-5, research shows that both AS and HFA are significantly different than autism with cognitive impairment (intelligence quotient <= 70), and therefore have different treatment needs. These needs primarily include specialized social skills training. Youth with AS/HFA who obtain sufficient social skills often report greater levels of quality of life and lower levels of anxiety and depression. Their parents also report less parental stress. Although a growing number of evidence-based social skill interventions exist, few use an experimental design and incorporate special interest areas (i.e., the pervasive interests of children with AS), generalization techniques (e.g., different settings, parent inclusion) or computer mediation, which research suggests is needed. Using an experimental design, this study investigated the incremental benefits of parent-guided social skills software (i.e., Social Express) in improving social, emotional and behavioral functioning in the child, as well as reduce parental-stress in the parent. Thirty youths with AS/HFA enrolled in a 9-week social skills group at a clinic participated in this study, as well as their parents. Half were randomly assigned to receive Social Express. Results indicated that the treatment group showed significant improvements in social motivation compared to the control group. No significant main effects were found in regards to other social skills, internalizing problems, adaptive skills, parental stress, or life satisfaction; however, it should be noted that this study is limited by a small sample size. Other significant effects may exist, and should be investigated in the future with a larger sample size.

Profiles Of African American College Students’ Risky Behaviors: General And Culturally-Specific Stress And Social Support As Factors Of Risk And Resilience?, Isha Walwina Metzger

Theses and Dissertations

Studies show that, while alcohol use and risky sexual activities increase during emerging adulthood, college students are more likely to engage in these behaviors than their non-student counterparts (Slutske et al., 2004). Researchers should explore risk behavior participation among African American youth, as they often face health disparities and more severe consequences of engaging in these acts than their White American counterparts (Sharma & Atri, 2006; Jackson, Hodge, & Vaughn, 2010). Although epidemiological and variable-centered studies often examine the drinking and sexual behavior of African American college students, there is a need for research utilizing a profile-oriented approach to explore …
