College Student Alcohol Use And Engagement In Prevention Programming, Alexis H. Branch, Shimona Kumar, Christina Mcgrath

UROP Posters

Social problems and adverse consequences have been associated with risky alcohol use (Paschall et al, 2015). Personalized Normative Feedback (PNF) has been utilized to address these problems (White and Hingson, 2014) by comparing students’ alcohol use to campus or national norms (Butler et al, 2009). The current investigation sought to understand differences in alcohol use behaviors in freshmen who did and did not report completion of a personalized feedback intervention (PFI) in a diverse sample of college students from the Spit for Science (S4S) project. S4S is a campus-wide, longitudinal study on the genetic and environmental factors that contribute to …

Adolescent Expressive Reluctance Exacerbates Risk For Substance Use Following Daily Hassles, Chad M. Hensberger, David W. Sosnowski M.S., Wendy Kliewer Ph.D, Kristina Mcguire M.S.

UROP Posters

Previous research has established a link between adolescent’s perceived daily hassles and subsequent adjustment, but less is known about factors that exacerbate this relationship. The purpose of the present study was to identify if adolescent’s reluctance to express emotions moderated the association between their perceived daily hassles and subsequent substance use (i.e., alcohol, marijuana, tobacco). Cross-sectional data were obtained from a larger study that examined the effects of exposure to community violence among low-income, urban adolescents (N = 260, M_age = 14.14, SD = 1.62 years; 92% African American; 54% female). Linear regression analyses controlling for adolescent age, …

Examining The Confirmatory Tetrad Analysis (Cta) As A Solution Of The Inadequacy Of Traditional Structural Equation Modeling (Sem) Fit Indices, Hangcheng Liu

Theses and Dissertations

Structural Equation Modeling (SEM) is a framework of statistical methods that allows us to represent complex relationships between variables. SEM is widely used in economics, genetics and the behavioral sciences (e.g. psychology, psychobiology, sociology and medicine). Model complexity is defined as a model’s ability to fit different data patterns and it plays an important role in model selection when applying SEM. As in linear regression, the number of free model parameters is typically used in traditional SEM model fit indices as a measure of the model complexity. However, only using number of free model parameters to indicate SEM model complexity …

Investigating Racial Bias In Perceptions Of Free Will, Courtney J. Alderson

Theses and Dissertations

The overarching goal of this study was to examine whether perceptions of others’ free will would differ depending on perceiver race as well as target race. The current study proposed that such a racial bias may be one mechanism by which racial disparities in medical treatment recommendations arise. By bridging findings from four different lines of research (i.e., the literatures on racial health and medical treatment disparities, racial bias, free will beliefs, and social identity), it was hypothesized that: (1) participants would perceive greater amounts of free will for a hypothetical racial ingroup patient than an outgroup patient; (2) such …

Perceived Financial Burden, Self-Management Behaviors, And Glycemic Control In Adults With Type 1 Diabetes, Megan Peter

Theses and Dissertations

People with type 1 diabetes must perform frequent self-management behaviors to maintain glycemic control. Those with higher diabetes distress tend to have worse glycemic control, indicated by higher A1C. Financial stress is common in adults with chronic diseases, but little is known about perceived financial burden in adults with type 1 diabetes or its associations with diabetes distress, self-management behaviors, or A1C. It is also unknown whether diabetes self-efficacy moderates the associations between perceived financial burden or diabetes distress with self-management behaviors.

Surveys were collected from 235 adults with type 1 diabetes. Structural equation modeling tested whether perceived financial burden …

Differences In Spatial Visualization Ability And Vividness Of Spatial Imagery Between People With And Without Aphantasia, Anita Crowder

Theses and Dissertations

Mathematics education researchers have examined the relationship between visualization and mathematics for decades (e.g., Arcavi, 2003; Bishop, 1991; Duval, 1999; Fennema & Tartre, 1985; Presmeg, 1986). Studies have linked spatial visualization ability, such as measured in mental rotation tasks, directly to mathematics self-efficacy (Pajares & Kranzler, 1995; Weckbacher & Okamoto, 2014), which in turn influences mathematics achievement (Casey, Nuttall, & Pezaris, 1997). With the important role that spatial visualization plays in learning mathematics, the recent identification of congenital aphantasia (Zeman, Dewar, & Della Sala, 2015), which is the lack of mental imagery ability, has raised new questions for mathematics education …

Prosecution As The "Soul Crushing Job:" Complexities Of Campus Sexual Assault Cases, Tammi L. Slovinsky

Theses and Dissertations

On April 4, 2011, the U.S. Department of Education issued a Dear Colleague Letter on campus sexual assault reaffirming the intent of Title IX, the 1972 law that prohibits discrimination sex-based under any education program or activity receiving federal financial assistance. In response to growing concern over due process rights for defendants, in September 2017 the guidance was rescinded. Public policy continues to evolve, leading to potentially lasting institutional changes on many college campuses. These developments include the formalization of campus investigations and adjudications, the development of campus coordinating committees and expanded support mechanisms for victims. In Virginia, laws passed …

Communicating Colorectal Cancer Risk To Average Risk Adults: Examining The Impact On Risk Perceptions And Health Behavior Intentions, Carrie A. Miller

Theses and Dissertations

Background. CRC risk can be reduced though lifestyle modification and regular screenings. Providing CRC risk feedback that promotes preventive behaviors to those at average risk has the potential to significantly reduce CRC morbidity and mortality.

Purpose. The purpose of this dissertation was to examine the impact of CRC risk assessment feedback among adults aged 50-75 with no personal or family history of the disease. The specific aims were to: (1a) test personalized (vs. generic) risk assessment feedback on individuals’ risk perceptions and intentions to engage in three risk-reducing behaviors (e.g., physical activity, diet, and screening); (1b) determine if the provision …

Validation Of Virginia's Juvenile Risk Assessment Instrument, Jessica P. Schneider

Theses and Dissertations

Utilizing a validated risk assessment tool to predict future offending is recommended as best practices in corrections by a number of professional organizations (Latessa & Lovins, 2010). Guided by the risk-needs-responsivity model, risk assessment tools have evolved to help inform criminal justice practitioners by identifying offenders most in need of intervention or supervision, guiding the case plan to optimize outcomes (Bonta & Andrews, 2007). The Virginia Department of Juvenile Justice (DJJ) utilizes the Youth Assessment and Screening Instrument (YASI) at all stages of contact with youthful offenders, including intake, probation, commitment, and parole (DJJ, 2016). However, risk assessment instruments do …

Predicting Arterial Oxygen Desaturation Events Via Patient Journal And Pulse Oximetry Data In Postoperative Ambulatory Surgery Patients, Charles R. Elam Iv

Theses and Dissertations

Associations between patient and procedural factors on the nature and quality of the immediate in-home recovery from anesthesia following ambulatory orthopedic surgery are unknown. Further, there is a paucity of outcomes research quantitatively categorizing in-home

patient recovery and safety following discharge from same-day orthopedic procedures. Tools are available, however, to shed light on outcomes in this population, and integration of such available measures is critical.

Ambulatory orthopedic surgery is a burgeoning specialty, with growth expected over the foreseeable future. The expected increased patient caseload subsequent to implementation of the Affordable Care Act and aging Baby Boom generation suggests greater morbidity …

The Experiences That Promote Success For Students With Intellectual Disability In Postsecondary Education, Kimberly S. Handsome

Theses and Dissertations

This in-depth qualitative, phenomenological (Smith & Fowler, 2009) research study attempted to understand the experiences of young adults with intellectual disability who had completed a 2-year, inclusive postsecondary education program. 13 participants (4 former students with ID, 5 parents, and 4 Postsecondary Education staff members) participated in semi-structured interviews. Interviews were coded to provide themes amongst each individual group of participants. A document review was also conducted to better understand the program components and add validity to self-reports from interviews. Results were analyzed and used to provide implications for future research and program development.

Police Officer Perceptions Of Organizational Justice And Body-Worn Cameras: A Civilizing Effect?, Carolyn Naoroz Ph.D.

Theses and Dissertations

This research sought to understand the potential association between officer perceptions of organizational justiceand officer perceptions of body-worn cameras (BWCs). A questionnaire was administered to a convenience sample of 362 officersfrom the 750 sworn personnel from the Richmond Police Department in Richmond, VA, yielding a response rate of 91% and representing 44% of the Richmond Police Department’s sworn employees. This study extends prior work by partially replicating a previous BWC survey conducted by leading body-worn camera scholars, utilizing a large sample from an urban mid-Atlantic police department. This study also extends prior work on officer perceptions of organizational justice …

A Practice Elements-Based Approach To Adherence Measurement, Stephanie Violante

Theses and Dissertations

The measurement of treatment adherence (i.e., the frequency and thoroughness with which a therapist delivers a treatment as designed) is critical to the field of implementation science, as adherence is often considered an indicator of successful implementation. Most existing instruments of treatment adherence are treatment protocol specific; however, this approach is costly, inefficient, and disallows cross-treatment and cross-study comparisons. Thus, there is a need for adherence instruments that can be used across treatment protocols. It has been suggested that an instrument that captures adherence at the practice element level would meet this need, as it would have utility across protocols …

Spatial Learning And Memory In Brain-Injured And Non-Injured Mice: Investigating The Roles Of Diacylglycerol Lipase-Α And -Β., Lesley D. Schurman

Theses and Dissertations

A growing body of evidence implicates the importance of the endogenous cannabinoid 2-arachidonyl glycerol (2-AG) in memory regulation. The biosynthesis of 2-AG occurs primarily through the diacylglycerol lipases (DAGL-α and -β), with 2-AG serving as a bioactive lipid to both activate cannabinoid receptors and as a rate limiting precursor for the production of arachidonic acid and subsequent pro-inflammatory mediators. Gene deletion of DAGL-α shows decrements in synaptic plasticity and hippocampal neurogenesis suggesting this biosynthetic enzyme may be important for processes of normal spatial memory. Additionally, 2-AG is elevated in response to pathogenic events such as traumatic brain injury (TBI), suggesting …

Influence Of Muscle Strength On Mobility In Critically Ill Adult Patients On Mechanical Ventilation, Audrey R. Roberson

Theses and Dissertations

Patients in the intensive care unit (ICU) setting are prone to develop muscle weakness and the causes are multi-factorial. Muscle strength in adult, critically ill patients on mechanical ventilation decreases with immobility. The influence of muscle strength on different muscle groups and its influence on progressive mobility in the adult, critically ill patient on mechanical ventilation has not been examined. Identifying muscle strength in this patient population can benefit overall muscle health and minimize muscle deconditioning through a progressive mobility plan. The objective of this dissertation was to describe muscle strength in different muscle groups and to describe the influence …

Structured Poetic Expressions For Emerging Adults Experiencing Bereavement, Kelcie D. Willis

Theses and Dissertations

Previous research has produced heterogeneous findings regarding the effectiveness of expressive writing in reducing grief symptomatology among the bereaved (e.g., Collison, 2016; Lichtenthal & Cruess, 2010; Stroebe et al., 2006). The purpose of this study was to address these mixed results by exploring the effects and linguistic characteristics of a novel writing task (i.e., the acrostic poem) among bereaved undergraduates, using an innovative data analysis technique (i.e., Linguistic Inquiry and Word Count). The current study recruited 68 undergraduates who had lost a loved one. Participants were randomly assigned to write over multiple days using the acrostic poem, emotional disclosure prompt, …

Relationships Among Parenting Stress, Parenting Practices, And Conduct Problems In African American Mothers Of Children With And Without Adhd, Amanda Parks

Theses and Dissertations

Parents of children with attention-deficit/hyperactivity disorder (ADHD) endorse increased levels of parenting stress and subsequently employ ineffective parenting practices. For children with comorbid conduct problems, mothers report more parenting stress than mothers of children with ADHD alone. I investigated the relationships among child ADHD diagnostic status, parenting stress, parenting behaviors (i.e., involvement and positive parenting) and child conduct problems in 78 African American mothers of children with and without ADHD. Mothers completed a demographic questionnaire, a semi-structured clinical interview, the ADHD Rating scale (also completed by teachers), the Impairment Rating Scale, the Parenting Stress Index – Short Form, and the …

"To Conceive With Child Is The Earnest Desire If Not Of All, Yet Of Most Women": The Advancement Of Prenatal Care And Childbirth In Early Modern England: 1500-1770, Victoria E.C. Glover

Theses and Dissertations

This thesis analyzes medical manuals published in England between 1500 and 1770 to trace developing medical understandings and prescriptive approaches to conception, pregnancy, and childbirth. While there have been plenty of books written regarding social and religious changes in the reproductive process during the early modern era, there is a dearth of scholarly work focusing on the medical changes which took place in obstetrics over this period. Early modern England was a time of great change in the field of obstetrics as physicians incorporated newly-discovered knowledge about the male and female body, new fields and tools, and new or revived …

Reducing Sepsis Mortality: A Cloud-Based Alert Approach, Janet A. Zink

Theses and Dissertations

The aim of this study is to examine the impact of a cloud-based CDS alerting system for SIRS, a precursor to sepsis, and sepsis itself, on adult patient and process outcomes at VCU Health System. The two main hypotheses are: 1) the implementation of cloud-based SIRS and sepsis alerts will lead to lower sepsis-related mortality and lower average length of stay, and 2) the implementation of cloud-based SIRS and sepsis alerts will lead to more frequent ordering of the Sepsis PowerPlan and more recording of sepsis diagnoses. To measure these outcomes, a pre-post study was conducted. A pre-implementation group diagnosed …

Decoding The Signaling Of The D2r-2ar Heteromer: Relevance To Schizophrenia, Miao Huang

Theses and Dissertations

Schizophrenia is a severe mental disorder affecting ~1% of world population. Two G protein coupled receptors (GPCRs): Gi-coupled dopamine D2 receptor (D₂R), and Gq-coupled serotonin 2A receptor (2AR), are targeted by the typical and atypical antipsychotic drugs to treat schizophrenia. These two receptors have been shown to co-localize in brain regions relevant to schizophrenia, including the ventral tegmental area (VTA), striatum, and prefrontal cortex (PFC). Studies in our lab characterized the integrated signaling of the D₂R-2AR heteromer and found that both the Gi activity of D₂R and the Gq activity of 2AR were potentiated …

The Impact Of Mother–Father Relationship, Social Support And Neighborhood Context On Preterm Birth, Timothy O. Ihongbe

Theses and Dissertations

Background: Preterm birth is a major public health concern in the US. Previous studies have suggested that quality of the mother-father relationship, social support, and neighborhood violence may be associated with preterm birth; however, findings are equivocal.

Objectives: The main objectives of this dissertation were: 1) to determine the modifying effect of perceived residential environment on the association between quality of mother–father relationship and preterm birth in a sample of African-American women, 2) to examine whether the receipt of social support modifies the association between neighborhood violence exposure and preterm birth in a nationally representative sample of US women, and …

Effects Of A 2-Week Exercise Intervention On Heart Rate Variability In Individuals With Low And High Anxiety Sensitivity, Hannah M. Kotarski

Theses and Dissertations

Anxiety Sensitivity (AS), the belief that anxiety-related sensations may have harmful implications, can alter autonomic nervous system (ANS) function. Exercise has previously been shown to reduce AS; however, the effects of an exercise intervention on heart rate variability (HRV), a measure of ANS function, has not been evaluated in individuals with high AS. This study sought to 1) compare resting HRV in individuals with either low (LAS) or high AS (HAS) and 2) evaluate the effects of a 2-week exercise intervention on HRV and AS. Using the Anxiety Sensitivity Index (ASI-3), participants were identified as LAS (n=9; ASI-3=5.89±1.39) or HAS …

Theses and Dissertations

One-Third of a Nation, the Second Amendment, a Living Newspaper Play

Thesis By Linda Ann Watt for a MFA Degree in Theatre Pedagogy

Documentary theatre, including living newspapers and verbatim theatre, use socio-political commentary at critical moments in history to disseminate facts and offer ideological critique dramatizing the crisis through the lens of emotion, which can incite societal change. This thesis explores this didactic medium with a written play about the second Amendment and gun violence.

Bed And Breakfast: The Role Of Sleep And Affect In Breakfast Intake, Ashley R. Macpherson

Theses and Dissertations

Breakfast intake is associated with numerous positive physical and mental health outcomes, yet breakfast skipping remains common in adults. Chronotype and sleep show potential as predictors of breakfast intake; however the existing literature has methodological limitations and fails to examine how psychological mechanisms might explain the relation between sleep and breakfast. The current investigation explored the association of means and variability of sleep behaviors (bedtime, midsleep, sleep duration) as predictors of breakfast intake frequency and high-protein breakfast intake frequency. Additionally, the role of positive and negative affect as mediators in the sleep—breakfast association was examined. Hierarchical regressions and PROCESS parallel …

A Stakeholder Examination Of Gestational Weight Gain Guidelines, Melissa Kwitowski

Theses and Dissertations

Obesity is a significant health concern for women of childbearing age. More than 40% of women have a Body Mass Index (BMI) in the overweight or obese ranges at the time they conceive, posing significant health risks for both mother and child. Excessive weight gain during pregnancy is common and associated with numerous deleterious complications. The Institute of Medicine published gestational weight gain (GWG) guidelines based on prepregnancy BMI. However, more than 50% of women gain in excess of these recommendations. Further, many women report receiving minimal guidance from their healthcare providers regarding weight gain, nutrition, and physical activity during …

Theses and Dissertations

The present study aimed to expand the knowledge base regarding incarcerated women’s experiences with violence and their mental health with the goal of identifying avenues for more tailored, compassionate responses to their mental health difficulties in both macro and direct practice contexts. To achieve this aim, a secondary data analysis was performed using data from the Survey of Inmates in State Correctional Facilities (SISCF) completed by the Bureau of Justice Statistics (BJS) in 2004. Six research questions pertaining to women’s experiences with violence and their mental health difficulties and service utilization guided the inquiry, which involved univariate, bivariate, and multivariate …

Longitudinal Relations Between Adhd Symptoms And Substance Use Across The Transition To College And Evaluation Of Promotive And Protective Factors, Melissa R. Dvorsky

Theses and Dissertations

The prevalence of substance use and related problems increases during adolescence and peaks in young adulthood with substantial increases during the transition from high school to college (Johnston et al., 2018). However, these increases are not universal for all students (White et al., 2006), and there is substantial variation in rates of substance use during the first year of college (Borasri et al., 2007; Frisher et al., 2007). It is important to identify the individual and environmental factors that serve as risk factors for substance use as well as factors that may promote or protect against use during the high …

Investigating The Presence And Correlates Of Anti-Thin Bias In Adults, Alexandria Davies

Theses and Dissertations

Weight stigma is associated with negative health outcomes across the BMI continuum. However, few studies have examined weight discrimination targeting people with low body weights. This investigation explored the presence of anti-thin bias, defined as the belief that people with low BMIs have undesirable personality characteristics. Participants were randomly assigned to read one of six vignettes about women that differed by race (White and Black) and weight status (slightly underweight, normal weight, and slightly overweight). Negative personality characteristics were more likely to be ascribed to both underweight and overweight women, compared with normal weight women. Furthermore, participants were significantly more …

Strengthening Social Networks Of Youth Aging Out Of Foster Care: Promoting Positive Adult Outcomes, Rachel D. Rosenberg

Theses and Dissertations

During the transition to adulthood, youth often rely on the people in their life for support. However, for transition-aged foster youth, these supports may not be available or may look different than supports available to youth in the general population. Relationships with supportive adults have been found to help former foster youth transition to adulthood, but little is known about the adults youth have in their network. Foster youth who report increased levels of social capital have been shown to experience higher levels of success in young adulthood. However, as former foster youth transition to adulthood, a lack of in-depth …

Does Emotion Regulation Moderate The Association Between Impairment And Depression In Adolescents With Adhd?, Laura D. Eddy

Theses and Dissertations

In comparison with their peers, adolescents with ADHD are at increased risk for developing depression, with prevalence estimates for comorbid depression ranging from 14% to 20%. Youth with comorbid ADHD and depression are at greater risk for multiple negative outcomes compared to youth with ADHD alone, including suspension from school, failing a grade, or difficulties in peer relationships. Identifying risk factors for depression among adolescents with ADHD is important for facilitating early identification and treatment efforts. Research completed to date indicates that interpersonal impairment and emotion regulation may mediate the relationship between ADHD and depression. However, a comprehensive longitudinal model …
