Examining Predictors Of Attitudes And Knowledge Of Registered Nurses And Nursing Students In Tennessee Toward Pregnant And Perinatal Women With A Substance Use Disorder, Jessica Patrylo

Electronic Theses and Dissertations

Substance use disorders (SUDs) among pregnant and perinatal women continue to be a national public health crisis. Furthermore, nursing students and perinatal nurses have historically negative and punitive attitudes toward this vulnerable population of women. As nurses are primary care providers for pregnant and perinatal women, this is troublesome as perinatal patients express feeling stigmatized by nurses whom they should be able to trust. This contributes to the reluctance of women to seek needed medical and prenatal care. Tennessee was the first state to criminalize drug use in pregnancy and has higher neonatal abstinence syndrome (NAS) rates, which were more …

Economic Insecurity, Poverty, And Parental Alcohol Misuse, Joey Tucciarone

Electronic Theses and Dissertations

Because parental alcohol misuse is associated with numerous negative outcomes for drinkers and other family members, it is important to examine factors predictive of alcohol misuse patterns among parents living with at least one child under the age of 18. Two possible factors include economic insecurity and poverty. This study sought to address whether measures of economic insecurity (i.e., housing and/or food insecurity in the past 12 months) and a dichotomous measure of poverty predict parental binge drinking and parental heavy alcohol consumption in a large population-based sample. It was hypothesized that economic insecurity and poverty, analyzed separately, would predict …

Bilateral Ground Reaction Force Jumping Asymmetry And Performance, Keith Painter

Electronic Theses and Dissertations

The prevalence of asymmetry in performance research has increased in recent years with mixed results. Much of the performance research has focused on unilateral jumping activities attempting to show relationships to other performance variables. However, bilateral ground reaction forces (bGRF) from jumps are more frequently assessed in athlete monitoring programs and the asymmetry from those jumps could be a simple addition to data already being collected. Research into bGRF asymmetries is lacking and no studies have addressed longitudinal changes. Additionally, research into the relationship of asymmetries to performance have infrequently used athletes. For these reasons, this dissertation will focus on …

Electronic Theses and Dissertations

The purpose of this study was to determine the relationship between Yo-Yo intermittent recovery testing ability and 20-meter sprint times in NCAA Division I men’s and women’s collegiate soccer players. Results show no significant (p = >0.05) relationship between the distance covered in the Yo-Yo IR1 test and 20-meter sprint times in the female players and a significant correlation between the two tests in the male players (r = -0.33). A non-significant relationship between the tests in female players may be due to greater variation in the total distance covered during the Yo-Yo IR1 test and small variation …

Interpersonal Needs And Suicide Risk: Examining Indirect Effects Of Internal Hostility And Feeling Forgiven, Kelley C. Berto

Electronic Theses and Dissertations

Suicide is a national public health concern, and unmet interpersonal needs (i.e., perceived burdensomeness, thwarted belongingness) may contribute to enhanced risk. However, mechanisms of action and certain protective variables are not well understood. The present study examined simple mediation models, with internal hostility as a mechanism of action between interpersonal needs and suicide risk. Additionally, our study examined the moderating role of various aspects of receiving forgiveness on the association between interpersonal needs and internal hostility in these simple mediation models. A community-based convenience sample was surveyed (N=712). Our findings indicated that internal hostility partially mediated the association …

LGBTQ+ people experience higher rates of chronic conditions, STIs, addiction, poor mental health, and cancer, which highlights the importance of capturing data regarding health. A growing concern is that social surveys fail to find meaningful ways to gather gender and sexuality data to understand possible health disparities for LGBTQ+ people. This study uses data from the General Social Survey to examine the physical and mental health outcomes of LGB people compared to straight people in a …

Evidence-Based Program Selection And Duration Of Implementation Of Social-Emotional Learning As Related To Student Growth And Non-Academic Outcomes, Colleen K. Weems

Electronic Theses and Dissertations

This quantitative, nonexperimental study addressed the gap between research-established benefits and outcomes of social-emotional learning implementation as compared to actual instances of implementation. It has been suggested that social-emotional learning as a systemic initiative is necessary for school health (Elias et al., 2013). Additionally, most educators relay some confidence in the importance of social-emotional learning; however, around half report actual implementation within their school (Atwell & Bridgeland, 2019).

Focusing on social-emotional learning as a whole as well as the specificity of use of CASEL SELect programs, the research questions of this study explored differences between implementation and usage, length of …

Perceptions Of Resilience-Informed Education In Postsecondary Instructors, Chelsea L. Robertson

Electronic Theses and Dissertations

Many studies have noted the detrimental impact adverse childhood experiences (ACEs) can have on individuals’ developmental trajectories and, as a result, the utilization of trauma-informed practices has been of increasing interest within the field of education. Most research on trauma-informed pedagogy is derived from samples of children in grades K-12, whereas research on trauma-informed teaching practices within higher education is comparatively scarce. The specific aims of the current investigation are two-fold. The first aim is to explore the effect of postsecondary instructors’ disciplinary specialization (i.e., person-thing orientation) on their receptivity to compassionate teaching practices. The second aim is to implement …

Forgiveness, Gratitude, Humility, And Spiritual Struggle: Associations With Religious Belief Status And Suicide Risk, Benjamin B. Hall

Electronic Theses and Dissertations

Religion is a known contributor to suicide risk, with both positive and negative effects. Negative religious experiences, such as spiritual struggle, can exacerbate suicide risk. Alternatively, religion may promote positive psychological characteristics associated with reduced suicide risk, such as forgiveness, gratitude, and humility. However, research has yet to assess how religious changes, including conversion and deconversion, affect the linkage between religious risk and protective factors and suicidal behavior. We conducted three studies assessing these associations across four belief status groups: life-long religious believers, former religious non-believers who now believe, life-long religious non-believers, and former religious believers who no longer believe. …

Neuroinflammation, Peripheral Inflammation And Gut Microbiome Profiles In Male Mice From Two Proposed Mouse Models Of Social Behavior Deficits, Sarah Parkinson

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder marked by social deficits and repetitive actions. A communication pathway exists between the brain and gut called the gut-brain axis. It is thought that gut bacteria can secrete signaling molecules, triggering inflammation across the body. These studies attempt to determine if markers are expressed in two mouse models of ASD behaviors, BTBR and a valproic acid model. Immunohistochemistry of ionized calcium binding adaptor molecule 1 from male mouse brain tissue showed no microglial activation in any group. Cytokine analysis did exhibit an increase in interleukin 1 (IL-1) in male adult mice only. …
