Adherence To Dietary Recommendations For Adolescents With Cystic Fibrosis, Kristine M. Durkin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Adhering to dietary recommendations and nutritional supplements to ensure adequate absorption of nutrients and malnutrition plays an important role in the health of patients with cystic fibrosis (CF). Non-adherence to the CF care regimen, including nutritional recommendations, is high in adolescents. Therefore, the overall goal of this study was to identify factors related to adherence to nutritional recommendations in adolescents with CF.

Method: A total of 42 adolescents (ages 12-18) were recruited from 5 CF centers across the US. Adolescents completed surveys measuring body image/satisfaction, health literacy, perceived barriers to enzyme use, and self-efficacy, as well as the quality …

Effects Of Depression And Stress On Oral Self-Care Among Perinatal Women In Appalachia: A Longitudinal Study, Jeongwi An

Graduate Theses, Dissertations, and Problem Reports (ETD)

Oral health during the perinatal period has an impact on the health of women and their offspring. Oral self-care behaviors are preventive methods that can be employed to maintain or improve oral health but may be compromised during the perinatal period. Identifying factors affecting oral self-care behaviors might provide direction on how to intervene in oral health during and after pregnancy. The purpose of this study was to investigate independent and interactive effects of depression and stress on oral self-care behaviors of perinatal women in Appalachia, given the burden of oral disease in this region. A total of 1,172 women …

Sleep And Cardiovascular Reactivity To An Acute Virtual Stressor, Alaina Grace Tiani

Graduate Theses, Dissertations, and Problem Reports (ETD)

Inappropriate response and magnitude of cardiovascular reactivity (CVR) to stress is a proposed mechanism through which environmental stressors are linked with poor cardiovascular health outcomes (Chida & Steptoe, 2010; Krantz & Manuck, 1984). Studies of reactivity to various laboratory tasks commonly control for factors known to influence CVR such as smoking, medication use, caffeine intake, and BMI; however, few have considered the influence of sleep on CVR. In order to determine whether sleep characteristics need to be assessed and considered in studies of CVR, this study aimed to examine the association between indices of sleep quality and the magnitude and …

Relation Of Child Feeding Behaviors & Caregiver Qualities To Adherence To Nutritional Therapy In Type 1 Diabetes Management, Corrine N. Ahrabi-Nejad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Type 1 diabetes (T1D) is a chronic illness, typically diagnosed within childhood, that affects the ability of the pancreas to produce insulin. Significant daily self-management behaviors are required to maintain metabolic control for patients with T1D. Nutritional therapy, including adequate intake of macronutrients, is one self-management behavior necessary to optimize health. Adherence to such nutritional guidelines is associated with improved glycemic control, decreased instances of acute health complications (e.g., hyperglycemia, hypoglycemia), and can also prevent insulin resistance. Despite the critical importance of nutritional therapy, adherence to these guidelines remains low within pediatric populations. Therefore, it is important and necessary to …

Psychology Faculty Research and Publications

Background

Posttraumatic stress disorder (PTSD) is associated with markers of accelerated aging. Estimates of brain age, compared to chronological age, may clarify the effects of PTSD on the brain and may inform treatment approaches targeting the neurobiology of aging in the context of PTSD.

Method

Adult subjects (N = 2229; 56.2% male) aged 18–69 years (mean = 35.6, SD = 11.0) from 21 ENIGMA-PGC PTSD sites underwent T1-weighted brain structural magnetic resonance imaging, and PTSD assessment (PTSD+, n = 884). Previously trained voxel-wise (brainageR) and region-of-interest (BARACUS and PHOTON) machine learning pipelines were compared in a subset of control …

Habit And Diabetes Self-Management In Adolescents With Type 1 Diabetes, C. Cummings, N. E. Benjamin, H. Y. Prabju, L. B. Cohen, B. J. Goddard, Astrida S. Kaugars, T. Humiston, A. H. Lansing

Psychology Faculty Research and Publications

Objective: The development of habit (i.e., behavioral automaticity, the extent to which a behavior is performed with decreased thresholds for time, attention [effort], conscious awareness, and goal dependence), for goal-directed health behaviors facilitates health behavior engagement in daily life. However, there is a paucity of research examining automaticity for Type 1 diabetes self-management in adolescence. This study examined if greater perceived automaticity for diabetes self-management was associated with increased daily self-management, decreased daily self-regulation failures in glucose checking, and more optimal daily glycemic levels in adolescents with Type 1 diabetes. Method: Adolescents aged 13–17 and diagnosed with Type 1 diabetes …

Development Of A New Measure To Assess For Poverty-Based Stress: The Poverty-Based Stressor Scale (Pbss), Brianna N. Allen

College of Graduate Studies: Theses & Dissertations

Poverty, typically measured by economic well-being or depravation, is the result of systemic flaws built into the structure of society that adversely impact multiple dimensions of health and well-being. The specific stressors that disproportionately impact low-income individuals are called poverty-based stressors, and they encompass multiple categories of risk including physical, psychosocial, and financial risks. Currently, there is not an adequate measure of poverty-based stressors for low-income adults in the United States (U.S.), which restricts our ability to accurately determine the effects of poverty on important health-related outcomes. The purpose of this dissertation was to develop a psychometrically sound measure of …

Coping Self-Efficacy As A Moderator In The Relationship Between Trauma And Disordered Eating, Bethany Owens Raymond

College of Graduate Studies: Theses & Dissertations

Disordered eating behaviors are associated with a myriad of detrimental health and mental health consequences (Ackard et al., 2003; Bryla, 2003; Karkkainen et al., 2018; Quick & Byrd-Bredbenner, 2013). Previous research identifies trauma as a risk factor for disordered eating behaviors and eating disorders (Brewerton, 2007). For instance, individuals with eating disorders are more likely to report trauma than individuals with no such history (Lejonclou et al., 2014). However, because not all individuals with a history of trauma exhibit disordered eating, it is important to identify what factors might moderate this relationship. The current study aims to investigate coping-self efficacy …

Feeling Fat: Theorizing Intergenerational Body Narratives Through Affect, Katie Cook

Theses and Dissertations (Comprehensive)

This study set out to understand the intergenerational movement and impact of obesity epidemic and anti-fat narratives that emerged after the 1950s in North America. Embedded in an Anglo-Western, neoliberal context, the current study sought to understand the impact of weight-based messaging on the embodied experiences of parents and their now-adult children. Working within a critical-transformative paradigm and drawing on post-humanism and new materialism, I conducted 19 narrative interviews with individuals born between 1955 and 1990, six of whom were mother-daughter dyads, as well as a body mapping workshop with five self-selecting participants over the course of three sessions. I …

Examining Harm Reduction In Housing First For Youth Experiencing Homelessness And Concurrent Mental Health And Substance Use Issues, Victoria Rozycki

Theses and Dissertations (Comprehensive)

Purpose: Housing First for Youth (HF4Y) is a youth-focused adaptation of the well-established Housing First (HF) program model to housing and service provision for individuals experiencing homelessness. Given that the experience of youth homelessness is associated with an increased likelihood of substance use issues, a central tenet of the HF4Y framework is the use of a harm reduction approach to substance use and addictions. However, research on HF4Y programming has yet to examine how harm reduction is specifically being implemented in these settings. The purpose of this thesis was to examine how the principles and philosophies of harm reduction are …

Development And Validation Of A New Methodological Platform To Measure Behavioral, Cognitive, And Physiological Responses To Food Interventions In Real Time, M.A. Vargas-Alvarez, H. Al-Sehaim, J.M. Brunstrom, G. Castelnuovo, S. Navas-Carretero, J.A. Martínez, E. Almiron-Roig

Articles

To fully understand the causes and mechanisms involved in overeating and obesity, measures of both cognitive and physiological determinants of eating behavior need to be integrated. Effectively synchronizing behavioral measures such as meal micro-structure (e.g., eating speed), cognitive processing of sensory stimuli, and metabolic parameters, can be complex. However, this step is central to understanding the impact of food interventions on body weight. In this paper, we provide an overview of the existing gaps in eating behavior research and describe the development and validation of a new methodological platform to address some of these issues. As part of a controlled …

Filling The Gaaapps: Generating Affirming Asian American Perinatal Psychological Services, Jennifer Yuen

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Women in the perinatal period face a unique set of mental health challenges, as they must navigate both physical changes and transitions in their life. Perinatal mental health has been linked to child outcomes, such as social emotional development, cognitive development, and physical growth. In addition, women of racial and ethnic minority groups are confronted with barriers to accessing services and are therefore less likely to utilize mental health services. While international attention has recently focused on the experiences of women of color in the perinatal period, Asian American women have been largely overlooked. This systemic literature review explores the …

It analyzes perceptions and experiences central in vaccination decisions. Methods: The analysis is based on 38 in-depth interviews with Finnish parents who have refused all or several vaccines for their children. The interviews were analyzed using qualitative content analysis. Results: Three categories of reasons were identified in the analysis: 1) risks and effects of vaccination – concern about and/or experiences of possible side-effects was the most important reason for avoiding vaccines; 2) distrust – participants did not trust vaccination recommendations …

Can Brazilian Jiu Jitsu Be A Viable Treatment Option For Law Enforcement Officers With Ptsd?, Megan Rinderer

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Law enforcement officers (LEO) are more likely to experience symptoms of PTSD when compared to the general population yet are less likely to seek mental health treatment (Jetelina et al., 2020). Given that LEO face unique occupational stressors and repeated exposure to traumatic events, treatment for PTSD among law enforcement populations poses unique challenges for clinicians. The combination of these variables precludes officers from seeking and receiving mental health services. Research regarding the efficacy of Brazilian Jiu Jitsu (BJJ) as a psychotherapeutic intervention is limited. To date, no studies have examined the use of BJJ to mitigate symptoms of PTSD …

Schizotypy, Lifestyle Behaviors, And Health Indicators In A Young Adult Sample, Thomas J. Dinzeo, Umashanger Thayasivam

College of Science & Mathematics Departmental Research

Problematic lifestyle behaviors and high rates of physical illness are well documented in people with schizophrenia, contributing to premature mortality. Yet, there is a notable absence of research examining general lifestyle and health issues in participants at risk for psychosis. This form of research may help identify concerns that exist during prodromal periods related to future outcomes. Accordingly, the current study examined lifestyle and health in a nonclinical sample of 530 young adults with varying levels of schizotypy. Increasing symptom severity was associated with greater somatic symptoms and poorer sleep quality across positive, negative, and disorganized domains. Elevated negative and …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

Moderate Prenatal Ethanol Exposure, Sex, And Housing Modify Spatial Navigation Behavior And Hippocampal Cell Firing In Adult Rodents, Christy Magcalas

Psychology ETDs

Prenatal alcohol exposure (PAE) is associated with structural and physiological changes that impact the central nervous system and can result in persistent negative consequences in a broad spectrum of cognitive and behavioral domains including deficits in spatial learning and memory and behavioral flexibility. The current study focuses on examining the behavioral and mechanistic consequences of PAE, sex and housing. Rats were tested in the Morris Water Task where they were trained to navigate to a goal location and tested in a pool shift manipulation. There were no significant differences between PAE treatment, sex, or housing groups during training, but there …

Recognizing The Unique Needs Of Women With Varied Pregnancy Loss Histories, Shalini Venkat

Honors Program Theses and Research Projects

Infertility is associated with psychological distress; women who experience miscarriage and recurrent miscarriage experience additional grief and trauma. Unfortunately, available psychological interventions for infertility are of limited efficacy; a new intervention is therefore needed. However, little is known about the psychotherapy preferences of women with infertility, and particularly whether miscarriage history is associated with treatment preferences. Thus, the current study evaluated the psychotherapy preferences of women with infertility as a function of miscarriage history. 410 North American women were recruited to complete an online survey assessing their quality of life, depressive symptoms, anxiety, and preferences of 14 psychotherapy techniques endorsed …

"Incorporating Behavior Analysis To Address Risk Factors For Obesity", Fawzia Khan

Honors Theses

There is a rising prevalence for obesity in the United States. Obesity is associated with health issues such as heart disease, diabetes, and other health complications including worsened mental health. Because of this, it is important to look for effective solutions to address risk factors, such as overeating and a sedentary lifestyle, that are associated with obesity. Applied behavior analysis, the application of learning principles to socially significant issues, has potential in addressing factors that lead to obesity. Functional analysis and the antecedent-behavior-consequence (ABC) model can help explain “cause and effect” relationships between environment and behavior and why and how …

Faculty, Staff and Students Publications

BACKGROUND: Games for health are a promising approach to health promotion. Their success depends on achieving both experiential (game) and instrumental (health) objectives. There is little to guide game for health (G4H) designers in integrating the science of behavior change with the art of game design.

OBJECTIVE: The aim of this study is to extend the Behaviour Change Wheel program planning model to develop Challenges for Healthy Aging: Leveraging Limits for Engaging Networked Game-Based Exercise (CHALLENGE), a G4H centered on increasing physical activity in insufficiently active older women.

METHODS: We present and apply the G4H Mechanics, Experiences, and Change (MECHA) …

Probiotic Intervention Improves Recovery Of Hippocampal Memory And Hippocampal Atrophy Following Disruption From High-Fat Diet In Adult Rats, Sanyourah A. El-Hulu

Honors Scholars Collaborative Projects

Presently, lifestyle factors such as chronic high-fat diet (HFD) consumption occurs concomitantly with weight gain and obesity (Gil-Cardoso et al., 2017; Stranahan et al., 2008). In turn, obesity has been associated with impairments to mental functioning, specifically to memory. Human epidemiological studies show that HFD intake containing saturated, and omega-6-fatty acids is associated with worse performance on a cognitive task whereas a lower fat diet containing omega-3-fatty acids is associated with a protective effect against cognitive decline (Zhang et al., 2006; Uranga et al., 2010). One explanation for this is the critical role of the gut bacteria in brain health. …

Early Protein Intake Predicts Functional Connectivity And Neurocognition In Preterm Born Children, Emma G.

Brain and Mind Institute Researchers' Publications

© 2021, The Author(s). Nutritional intake can promote early neonatal brain development in very preterm born neonates (< 32 weeks’ gestation). In a group of 7-year-old very preterm born children followed since birth, we examined whether early nutrient intake in the first weeks of life would be associated with long-term brain function and neurocognitive skills at school age. Children underwent resting-state functional MRI (fMRI), intelligence testing (Wechsler Intelligence Scale for Children, 5th Ed) and visual-motor processing (Beery-Buktenica, 5th Ed) at 7 years. Relationships were assessed between neonatal macronutrient intakes, functional connectivity strength between thalamic and default mode networks (DMN), and neuro-cognitive function using multivariable regression. Greater functional connectivity strength between thalamic networks and DMN was associated with greater intake of protein in the first week (β = 0.17; 95% CI 0.11, 0.23, p < 0.001) but lower intakes of fat (β = − 0.06; 95% CI − 0.09, − 0.02, p = 0.001) and carbohydrates (β = − 0.03; 95% CI − 0.04, − 0.01, p = 0.003). Connectivity strength was also associated with protein intake during the first month (β = 0.22; 95% CI 0.06, 0.37, p = 0.006). Importantly, greater thalamic-DMN connectivity strength was associated with higher processing speed indices (β = 26.9; 95% CI 4.21, 49.49, p = 0.02) and visual processing scores (β = 9.03; 95% CI 2.27, 15.79, p = 0.009). Optimizing early protein intake may contribute to promoting long-term brain health in preterm-born children.

Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs (RDDs) are the most robust quasi-experimental design, but current statistical models are limited to estimates for the simple causal relationship between only two variables: the independent and dependent variables. In practice, intervening variables (or mediators) are often observed as part of the causal chain. Mediators explain the why and how a treatment or intervention works. Therefore, mediation and RDD analysis combined can be a useful tool in identifying key components or processes that make intervention programs effective while making causal inferences for improving student achievement, despite natural constraints, limitations, and ethical considerations. Without an integrated framework of …

Using Self-Management Procedures To Decrease Social Media Usage In Adults, Olivia Joy Solari

Graduate Theses/Dissertations

Social media is a widely used tool and the effects it has on well-being and productivity levels are well known. Due to widespread concern about the negative effects (e.g., addiction, reduced productivity, unhappiness) of social media there is increased interest in methods for reducing this behavior. Self-management techniques have shown great utility for managing behavior. The current study used a changing-criterion design with an embedded reversal to determine the effectiveness of a self-management treatment package on decreasing participant social media usage. The treatment package consisted of feedback, self-monitoring, goal setting, and a token economy. Results of the current study show …

Graduate Theses/Dissertations

This study examined body image among female high school athletes and college athletes across different sports. Athletes participating in track and field, tennis, cross country, dance, cheer, softball, golf, basketball, soccer, and volleyball completed self-report questionnaires assessing various components of body image including the Body Shape Questionnaire (BSQ), Sociocultural Attitudes Towards Appearances Questionnaire (SATAQ-4), and an edited version of the CHEER Survey. Responses on the questionnaires were analyzed to evaluate differences between high school and college athletes. No differences were found between high school and college athletes on measures of shape/weight concerns, sociocultural pressures for thinness, or internalization of the …

Feasibility And Efficacy Of Virtual Darkness In Reducing Intra-Individual Sleep Variability Among Young Adults With Insomnia, Samantha Nicole Sherwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

BackgroundInsomnia impacts 30% of people and is associated with increased risk for medical and psychiatric illness. However, pharmacological treatments for sleep yield mixed results and often result in undesirable side effects indicating a need for novel insomnia interventions. Sleep patterns also demonstrate high intra-individual variability which may be associated with greater daytime impairment, and sleep-wake cycles are strongly affected by the timing of exposure to blue-green wavelength light. Virtual darkness, a novel intervention, blocks blue wavelength light from reaching the eye to simulate actual darkness on retinal cells sensitive to light. Therefore, the purpose of the current study is to …

Racial/Ethnic Disparities In Mental Health Diagnosis Of Maltreated Youth, Shadie Burke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Racial/ethnic marginalized youth are more likely to receive a misdiagnosis of a mental health disorder than their White peers. Misdiagnosis contributes to existing disparities for racial/ethnic marginalized groups by leading to longer durations of untreated and worsening mental health symptoms. For maltreated youth, receiving a misdiagnosis can lead to a failure to connect with appropriate mental health services, medication regimens, therapeutic foster homes, and academic and developmental resources. To date, very few empirical studies have identified disparities in mental health diagnosis among racial/ethnic marginalized maltreated youth. The present study examined two key research questions: (1) what racial/ethnic disparities in diagnoses …
