Alternative Tobacco Products & Depressive Symptoms Among Young Adults, David Marsden

Dissertations & Theses (Open Access)

The association between cigarette use and depression has been documented in many studies. Fewer studies have examined other tobacco products such as electronic cigarettes (e-cigarettes) and hookah that are used by young adults. This study examined whether increased frequency of use of these products was associated with depressive symptoms in a cohort of n=5,236 Texas college students followed from 2014 to 2017. A hierarchical model showed that increased frequency of single product use of cigarettes, refillable e-cigarettes and hookah was associated with depressive symptoms. Refillable and disposable e-cigarettes were examined separately and results did not provide evidence of a different …

The objective of this research was to analyze the relationship between nursing safety work culture in inpatient nursing units of a specialty academic hospital and their patients’ perception of safety using quantitative and qualitative methods. The aim of the quantitative study was to quantitatively evaluate whether nursing safety culture, as measured on the Hospital Survey on Patient Safety Culture (HSOPS) safety questions of the institutional employee opinion survey, was associated with patients’ perception of safety during their inpatient care, as measured by responses on the inpatient Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. The aim of the …

Exposure To Ambient Air Pollution And Fetal Death In Harris County, Texas, Amal Rammah

Dissertations & Theses (Open Access)

The evidence from studies of maternal ambient air pollutant exposure (including O3, fine particulate matter (PM2.5) and PM2.5 metal constituents) and stillbirth is limited and equivocal. There is also limited evidence of the acute effect of temperature increases in the week preceding delivery and stillbirth. In the first investigation of ambient air pollution, temperature and stillbirth among a large cohort of women in Harris County, Texas, we obtained birth and fetal death records from 2008-2013 and estimated weekly residential levels of apparent temperature and ozone (O3), fine particulate matter (PM2.5), nitrogen dioxide (NO2) and PM2.5 metals from the local monitoring …

Identifying Risk Factors Associated With Cardiovascular Disease Risk In Lesbians, Sofia S. Velazquez

Dissertations & Theses (Open Access)

Cardiovascular disease (CVD) is the leading cause of female deaths in the United States (1). While women, in general, are at risk for CVD, current research indicates that sexual minority women (i.e. lesbians and bisexual women [SMW]) may be at greater risk for CVD than heterosexual women. This heightened risk potentially stems from an increased prevalence of traditional CVD risk factors in SMW, creating health disparities between SMW and their heterosexual counterparts (2). Further research into this high-risk population is needed, in order to minimize these disparities.

The purpose of this study was to establish differences in the prevalence of …

Effects Of Extreme Precipitation On Gastrointesitnal Related Hospital Admissions In Texas, Sharmila Giri

Dissertations & Theses (Open Access)

Extreme precipitation has been implicated in more than 51% of the waterborne disease outbreaks in the United States between 1948-1994. With increased incidence of extreme precipitation projected to be more likely due to ongoing climate change, the burden of waterborne disease is expected to rise even in the United States where drinking water is considered to be one of the safest in the world. In this study we aim to quantify the risk of extreme precipitation on gastrointestinal (GI) related hospital admissions by using meteorological and emergency hospital data from twelve major metropolitan statistical areas (MSA) of Texas from year …

Hours Of Gaming Or Non-Academic Computer Use, Substance Use, Mental Health Status And School Performance Among Texas Adolescence: Findings From The 2017 Yrbs In Texas, Shanxiazi Gao

Dissertations & Theses (Open Access)

Online gaming activities among adolescents and adults has increased exponentially in the last decade, and mental health issues associated with excessive gaming have drawn attention from health care professionals worldwide (Griffith, 2016). Recognizing this trend, American Psychiatric Association (APA) categorized gaming disorder/addiction as a mental health condition in 2013 in an effort to prevent the expansion of relevant mental health issues (American Psychiatric Association, 2013). Additionally, the World Health Organization (WHO) declared gaming disorder/addiction as a mental health disease, (World Health Organization, 2018). As a result of this declaration, Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has established nine …

Quantifying The Impact Of Laboratory And Care Systems On Relinkage To Hiv Care In A Southern, Urban Environment, Kellie L. Watkins

Dissertations & Theses (Open Access)

Background: HIV viral suppression reduces the likelihood of transmission to just 5%,1 demonstrating the critical link between care and prevention, yet only 51% of people living with HIV (PLWH) were retained in care and 46% achieved viral suppression in the Houston area (2012), with the out-of-care (OOC) population increasing between 2008-2011.2,3

Methods: Record-search investigations across HIV surveillance and care data systems determined if potentially OOC persons referred to the Houston Health Department (HHD) from 2013-2015 (N=1287) qualified for public health follow up. A portion were randomized to a non-intervention group (n=200) to assess the program effectiveness. Participants without a disposition …

Adverse Childhood Experiences, Depression, And Resilience In African-American Adolescents, Jamie C. Freeny

Dissertations & Theses (Open Access)

Research shows that exposure to adverse childhood experiences (ACEs) is common among adolescents; however, no studies have examined the prevalence of ACEs in a racially homogenous sample of African-American adolescents. Thus, the present study examined the cumulative and individual prevalence of ACEs in African-American adolescents. Data were collected from African-American adolescents (n = 241) who attended youth events hosted by churches in Houston, TX. An expanded ACEs tool was used to collect data. ACE scores were summed and dichotomized to 0-3 ACEs versus 4-19 ACEs because a score of four or more indicates a higher risk for adverse mental and …

Development And Usability Testing Of Quit4health, A Smoking Cessation Smartphone App For Young Adults, Katarzyna Czerniak

Dissertations & Theses (Open Access)

Tobacco use is the leading cause of death in the United States. As of 2016, 23.5% of American 18-25 year olds reported having used cigarettes in the last month compared to 20.2% of adults and only 3.4% of adolescents. Due to the efficacy and widespread general use of mobile technology today, mobile-phone health, or mHealth apps, have become increasingly popular methods of delivering smoking cessation programs. However, there is a lack of evidence in regards to the quality and the effectiveness of using mHealth to deliver smoking cessation interventions to young adults. This study aims to fill this gap to …

Factors Associated With Civilian And Police Officer Injury During 10 Years Of Officer-Involved Shooting Incidents: A Cross-Sectional Analysis, Ellen Paddock

Dissertations & Theses (Open Access)

Purpose. Law enforcement officer-involved shootings are uncommon events in the context of encounters with the public, but extreme situations which have the potential to pose immense harm to individuals and communities. Previous research demonstrates that a large proportion of such incidents result in injury or death, most commonly to civilians, but in some cases to officers as well. However, there has been little study of what factors are associated with injury during such incidents, and whether these factors might differ for civilians compared to officers. This study examined the factors associated with both civilian and officer injury and/or fatality during …

Sociodemographic Determinants Of Mental Health Outcomes Among Unhealthy Weight Youth In The United States, Chenchita Malolan

Dissertations & Theses (Open Access)

Background

The prevalence of unhealthy weight (defined as a body mass index ≥ 85th %ile for age and sex) among children and adolescents in the United States remains unacceptably high. In parallel, the prevalence of mental health issues in youth is rising as well. Current research shows a strong association between overweight/obesity and poor mental health outcomes. Specifically, youth of unhealthy weight have higher rates of anxiety and depression. The objective of this study is to evaluate the specific the current (2016-17) population-level prevalence of unhealthy weight, mental health issues and the sociodemographic (e.g. sex, age, race, ethnicity, household income) …

A Secondary Data Analysis For The Refinement Of Empirical Modelling For The Estimation Of Environmental Health & Safety Program Resourcing For Colleges And Universities, Seth Michael Parker

Dissertations & Theses (Open Access)

The use of potentially hazardous physical, chemical, biological, and radiological agents is inherent to the teaching, research, and services missions of any university. To manage the risks associated with these agents, it is common for universities to host environmental health & safety (EH&S) programs to protect the safety of the institution’s students, faculty, staff, and visitors. However, since EH&S programs in universities are primarily focused on prevention, it is difficult to estimate the appropriate “industry average” in terms of budget and staffing resources a particular university needs for such programs. Historically, the Campus Safety, Health, and Environmental Management Association (CSHEMA) …

Sequential Monitoring Of Adaptive Randomized Clinical Trials With Sample Size Re-Estimation, Jun Yu

Dissertations & Theses (Open Access)

Clinical trials are complicated and involve human beings. Therefore, lots of ethical and efficient objectives are expected to be achieved. These objectives include maximizing the power of detecting the treatment effects, assigning more patients to the better treatments, saving the cost and time, and controlling the type I error rate. A variety of adaptive designs have been proposed to achieve different aims, among which sequential monitoring and sample size re-estimation are very popular in real clinical trials. In addition, adaptive randomization designs sequentially update the allocation probability aiming to target different allocation proportions and achieve different aims. Hu and Rosenberger …

Acculturation And Internalizing Problems Among Latino Youth: A Meta-Analytic Review, Juventino Hernandez Rodriguez

Graduate Theses and Dissertations

Some studies have found acculturation to be a positive predictor of internalizing problems (i.e., anxiety and depression) in Latino youth (Gonzales et al., 2002), whereas other studies have revealed no relation or a negative relation between acculturation and internalizing problems (Smokowski, Buchanan, & Bacallao, 2009). Narrative reviews of this literature exist (Gonzales et al., 2002; Gonzales et al., 2009) but a quantitative synthesis of the literature has not been conducted. After a systematic literature search that identified 38 studies meeting inclusionary criteria, a meta-analysis was performed to estimate the size and direction of the relation between acculturation and internalizing problems. …

Investigating Affective Pathways For The Influence Of Justification On Self-Control, Morgan Hill

Graduate Theses and Dissertations

People struggle with temptation in their everyday lives. Research often attributes failures in self-regulation to overwhelming and uncontrollable impulses. However, research also supports the idea that cognitive factors (e.g., justification) can license tempting behavior and allow individuals to behave in ways that run counter to their long-term goals. In addition, it is likely that affect plays a role in justification-based self-control failure. The current set of three studies investigated the role of affect in justification-based self-control failure. Study 1 tested the prediction that recall of past successes would result in increased positive affect. Study 2 assessed whether justification results in …

Values Vs. Self-Interest As Determinants Of Attitudes: Through A Construal Level Theory Lens, (Sometimes) Self-Interest Wins, Austin D. Eubanks

Graduate Theses and Dissertations

The present study (n = 335) attempted to conceptually replicate Hunt, Kim, Borgida, and Chaiken (2010) with a high-powered design to investigate whether values and self-interest differentially impact attitudes depending on psychological distance. Participants were assigned to complete a task that made self- or other-focused values more accessible, then indicated their attitudes about a student fee increase at a university to fund scholarships the participants would not be eligible to receive (thus going against their own financial self-interest for the well being of someone else). The memo describing the fee increase was manipulated such that the increase would be occurring …

A Support Program For College Students With Autism Spectrum Disorder: The Functioning Of Participants Versus Non-Participants And The Role Of Program-Sponsored Mentoring, Ayla Raven Mapes

Graduate Theses and Dissertations

Increasingly more students with autism spectrum disorder (ASD) are attending college. In response, many colleges are now offering these students the extra support of an Autism Support Program (ASP), many of which include a mentoring component. This study is one of only a handful of attempts to examine these programs empirically. Using a small sample of college students who identified as having ASD, I compared participants and non-participants of a university ASP. An online survey was used to assess demographic characteristics and pre-college academic performance, as well as students’ functioning across the following domains: social, adaptive, academic, emotional, and having …

Diurnally Active Rodents For Laboratory Research, Roberto Refinetti, G. J. Kenagy

Psychological Sciences Faculty Publications and Presentations

Although inbred domesticated strains of rats and mice serve as traditional mammalian animal models in biomedical research, the nocturnal habits of these rodents make them inappropriate for research that requires a model with human-like diurnal activity rhythms. We conducted a literature review and recorded locomotor activity data from four rodent species that are generally considered to be diurnally active, the Mongolian gerbil (Meriones unguiculatus), the degu (Octodon degus), the African (Nile) grass rat (Arvicanthis niloticus), and the antelope ground squirrel (Ammospermophilus leucurus). Our data collected under 12L:12D light-dark cycles confirmed and expanded …

Relating Rsv Genetic Diversity To Global Transmission Dynamics, Rebecca J. Fisk

Dissertations & Theses (Open Access)

Many studies of Respiratory Syncytial Virus (RSV) have relied on analyses of the Major Surface Glycoprotein G gene (G gene). Global transmission patterns have not been well studied due to lack of systematic global surveillance efforts. This study used phylogenetic analysis of full genome data, categorized by geo-region, to determine the sources of RSV A and B infection in Chile and Houston, Texas. Additionally, disease severity studies have generally focused on outcomes associated with a single genotype. In this study we developed a statistical phylogenetic approach to explore the relationship between tree topology and disease severity. Disease severity data included …

Observed Cooking Behaviors Of Families With And Without Childhood Cancer Survivors And The Development Of A Healthy Cooking Assessment Tool, Margaret Pleta Raber

Dissertations & Theses (Open Access)

Diet is a modifiable risk factor for several cancers and other chronic diseases. Cooking skills are a target for dietary intervention, with much of the general population reporting infrequent and inadequate home preparation of meals. Childhood cancer survivors (CCS) are a population at high risk of several chronic conditions including secondary cancers that may be influenced by home cooking behaviors. We conducted observations of food preparation practices in 29 parents of healthy school-aged children and 11 parents of CCS. Observations included an audio and video recording of one evening meal per family. Parents were asked to wear a small body …

Characterizing Young Adult Exposure And Engagement With Social Media Tobacco And Nicotine Product Marketing And Messaging, Stephanie L. Clendennen

Dissertations & Theses (Open Access)

Tobacco use remains a critical public health issue in the United States. Young adults are disproportionately affected by high rates of tobacco use and heavily targeted by tobacco marketing. Social media has become an important source of exposure to tobacco and nicotine product marketing and messaging for young adults. This dissertation examined the prevalence and socio-environmental characteristics associated with young adults’ exposure to and engagement with tobacco-related social media (paper 1); the prospective associations between young adults’ exposure and engagement and tobacco and nicotine product use (paper 2); and young adults’ experiences with tobacco and nicotine product messaging on social …

Race, Social Class, And Child Abuse: Content And Strength Of Medical Professionals’ Stereotypes, Cynthia J. Najdowski, Kimberly M. Bernstein

Psychology Faculty Scholarship

Black and poor children are overrepresented at every stage of the child welfare system, from suspicion of abuse to substantiation. Focusing on stereotypes as a source of bias that leads to these disparities, the current study examines the content and strength of stereotypes relating race and social class to child abuse as viewed by medical professionals. Doctors, nurses, and other medical professionals (Study 1: N = 53; Study 2: N = 40) were recruited in local hospitals and online through snowball sampling. Study 1 identified stereotype content by asking participants to list words associated with the stereotype that …

Cost Of Caring: The Effects Of Euthanasia On Animal Shelter Workers, Kim L. Nguyen-Finn

Theses and Dissertations

This mixed-methods study focuses on animal shelter workers, a population that has often been overlooked in research and clinical practice, and the emotional strains of the task of euthanasia. The effects of employment in a kill or no-kill shelter, participation in euthanasia, and number of years employed on mental health issues of substance abuse, anxiety, depression, secondary traumatic stress, and burnout were examined. A three-way MANOVA was run to test the hypothesis that there is a cell effect among the type of shelter employed in, participation in euthanasia, and years of experience on mental health, which was not supported by …

Age-Based Differences In The Usefulness Of Resources: A Multi-Study Investigation Of Work And Well-Being Outcomes, Lale Muazzez Yaldiz

Dissertations and Theses

The labor force is aging globally. It is projected that the number of older workers will increase in the workforce in the near future. At the same time, it is estimated that workplaces will grow more age-diverse, where younger and older workers will work side-by-side more often than they used to. These demographic shifts in the workforce necessitate a further understanding of the differences between the values, needs and motivation, and work outcomes of employees of different ages. To this end, few studies to date have investigated whether job-related resources are differentially useful for the work and non-work outcomes of …
