Fire Department Support And Physical Activity Of Volunteer Firefighters: A Cross-Sectional Examination, Sarah Wagner

Dissertations and Theses (Open Access)

Greater health and fitness of volunteer firefighters protects them from cardiovascular disease-related deaths, reduces risk of injury, and improves job performance, which subsequently provides better protection for the majority of the U.S. population who is served by volunteers. Given the strong social support system characteristic of the U.S. fire service, there seems to be potential opportunity to influence the behaviors of firefighters by creating a culture that promotes healthy habits rather than unhealthy. Objective: Determine the association between fire department culture’s encouragement of physical activity and volunteer firefighters’ moderate- to vigorous-intensity aerobic activity. Methods: A cross sectional analysis was performed …

Evaluating The Impact Of Early Initiation Of Antiretroviral Therapy (Art) On Patient Outcomes Among Hiv-Infected Adolescents And Young Adults In Uganda, Hilda Sekabira Nakalema

Dissertations and Theses (Open Access)

Introduction: Since the introduction of anti-retroviral therapy (ART), treatment initiation criteria have continually been revised to start these lifesaving drugs before onset of advanced disease and optimize ART benefits for people living with HIV. However, little is known about the effect of these changes on treatment outcomes among young people. We evaluated the effect of such a policy change on long term adherence and treatment outcomes among young people, aged 15-24 years.

Methods: We conducted a retrospective cohort analysis of young people, 15-24years old, who started ART from January 2012 – December 2016. We used administrative data from the District …

Ends Device Types And Subsequent Use Of Combustible Tobacco Products Among Texas Youth, Aslesha Sumbe

Dissertations and Theses (Open Access)

The aims of the study were to determine whether ENDS device types (i.e., disposable devices, replaceable cartridges, and refillables) at initial, or first ENDS use is longitudinally associated with subsequent initiation of combustible tobacco products (cigarettes, hookah, cigars) and continued, past 30-day use of combustible and ENDS products. This study is a secondary analysis of data from the Texas Adolescent Tobacco and Marketing Surveillance system (TATAMS) study, a longitudinal cohort study of students who were in the 6th, 8th, and 10th grades (n = 3907) during the 2014-2015 academic year. Data were collected every 6 months, from 2014-2018. Using data …

Dynamic Competing Risk Model For Multi-Type Recurrent Events With Dependent Termination, Alokananda Ghosh

Dissertations and Theses (Open Access)

Cardiovascular disease (CVD), defined by the World Health Organization (WHO) as diseases that involve the heart and/or blood vessels is the number one cause of morbidity and mortality worldwide. In the United States more health care dollars are spent managing and treating CVD and/or its complications than any other disease process. Coronary heart disease (CHD) is the leading cause of deaths (43.8%) attributable to CVD, followed by stroke (16.8%), hypertension (9.4%) and heart failure (HF) (9%). CVD-related deaths and attendant morbidities, which include lifelong disability are in many cases preventable. This research proposes a dynamic risk model that handles multi-type …

Scoring Divergent Thinking Tests: A Review And Systematic Framework, Roni Reiter-Palmon, Boris Forthmann, Baptiste Barbot

Psychology Faculty Publications

Divergent thinking tests are often used in creativity research as measures of creative potential. However, measurement approaches across studies vary to a great extent. One facet of divergent thinking measurement that contributes strongly to differences across studies is the scoring of participants’ responses. Most commonly, responses are scored for fluency, flexibility, and originality. However, even with respect to only one dimension (e.g., originality), scoring decisions vary extensively. In the current work, a systematic framework for practical scoring decisions was developed. Scoring dimensions, instruction-scoring fit, adequacy of responses, objectivity (vs. subjectivity), level of scoring (response vs. ideational pool level), and the …

Creativity Assessment In Psychological Research: (Re)Setting The Standards, Baptiste Barbot, Richard W. Hass, Roni Reiter-Palmon

Psychology Faculty Publications

This commentary discusses common relevant themes that have been highlighted across contributions in this special issue on 'Creativity Assessment: Pitfalls, Solutions, and Standards.' We first highlight the challenges of operationalizing creativity through the use of a range of measurement approaches that are simply not tapping into the same aspect of creativity. We then discuss pitfalls and challenges of the three most popular measurement methods employed in the field, namely divergent thinking tasks, product-based assessment using the consensual assessment techniques, and self-report methodology. Finally, we point to two imperative standards that emerged across contributions in this collection of articles, namely transparency …

Predicting Counterproductive Work Behavior With Explicit And Implicit Measures Of Conscientiousness, Agreeableness, And Emotional Stability, Jimmy Zheng

Electronic Theses and Dissertations

The current study leveraged the stressor-emotion model of CWB, the reflective-impulsive model of behavior, and theories of explicit and implicit personality to investigate the roles explicit and implicit aspects of personality, and work stressors have in influencing CWB. The stressor-emotion and reflective-impulsive models suggest that in addition to reflective (i.e., explicit) processes, impulsive (i.e., implicit) processes may also influence CWB because the act can be motivated by negative emotions induced by frustrating working conditions. Theories of personality and motivation suggest that conscientiousness, agreeableness, and emotional stability predict CWB because these traits motivate people to pursue goals that reduce or increase …

Group Composition Characteristics As Predictors Of Shared Leadership: An Exploration Of Competing Models Of Shared Leadership Emergence, Richard Currie

Electronic Theses and Dissertations

The study of leadership in organizations has received much research attention over the past several decades. However, most of this research has examined hierarchical structures of leadership wherein one individual leads, or is perceived to lead, several other individuals. With a growing number of organizations structuring employees within teams or work groups, researchers have begun studying the ways in which leadership operates in groups. One alternative to the traditional hierarchical structure is for leadership to be distributed or shared in groups such that multiple group members contribute to the overall leadership function of the group. As a result, researchers have …

The Profession Of Modeling And Simulations: Unifying The Organization, John Lord

Electronic Theses and Dissertations

The organization of Modeling and Simulation (M&S) as a profession started in the early twenty-first century spurred by the advent of computers and the vast networking capabilities of contemporary computing. M&S is still in its infancy when compared to other disciplines, such as engineering, computer science and mathematics. However, the profession has experienced significant growth in part due to the varied use of M&S techniques and tools within almost every discipline. Professional organizations and academic programs supporting M&S across the country have started to materialize. In a short timeframe, the growth of these supporting organizations has outpaced their ability to …

Differentiating Cognitive Deficits Between Adhd And In Utero Polysubstance Exposure, Dylan J. Seitz

Doctor of Psychology (PsyD)

ADHD is the most prevalent psychiatric disorder in children, affecting their executive and overall well-being as a result (Barkley, 2014; Shaw, Gogtay, & Rapoport, 2010). A rampant increase in new diagnoses of ADHD suggests the potential for misdiagnosis. Stimulants are the first line of treatment and associated with a number of deleterious long-term consequences for those misdiagnosed (Urban & Gao, 2014a). This is of particular concern for children prenatally exposed to substances as in utero use acts on similar neural mechanisms impacted by ADHD – leaving the children vulnerable to misdiagnosis and contraindicated intervention (Derauf, Kekatpure, Neyzi, Lester, & Kosofsky, …

Serial Neuropsychological Assessment Toward A Reliable Concussion Protocol, Daniel J. Soden

Doctor of Psychology (PsyD)

With more than 10,000 Sports Related Concussions (SRCs) per year at the collegiate level, interdisciplinary teams are often tasked with determining when an athlete may return to activity (Zuckerman et al., 2015). Due to neurochemical changes following an SRC, athletes are vulnerable to further injury if they suffer another head injury before given appropriate time to heal (Giza & Hovda, 2014). Cognitive testing is routinely utilized to detect the presence of cognitive dysfunction and aid in individualized treatment planning. Because athletes often demonstrate practice effects when retested, it is difficult to distinguish if the athlete is demonstrating cognitive dysfunction. Reliable …

Healthy Life Choice: Using The School-Based Program To Facilitate Change, Jennifer Shaheed

Doctor of Psychology (PsyD)

Research highlights the multiple determinants of weight including poverty, nutrition, and physical activity (Miguel-Berges, 2018). Children and adolescents living in rural areas are at greater risk than their urban counterparts. Regarding physical activity, there are often fewer recreational resources and the high poverty rate precludes transportation or additional fees associated with many extracurricular activities. In response to this problem, research has shown the educational environment is a point of access to reinforce health education and behavior. One evidenced-based program showing significant outcome in improving health behavior is the Healthy Lifestyle Choices (HLC) which is designed to be delivered in an …

A Program Evaluation Of Physician Medical Clinic’S Approach To Chronic Pain, William Summers

Doctor of Psychology (PsyD)

Chronic pain costs up to $635 billion dollars annually and impacts 25.3 million adult U.S. citizens (Nahin, 2015). Treatment options have typically included opioid medications, which potentially causes harm with long-term use and has contributed to an epidemic of opioid misuse. Treatment has expanded beyond monotherapy to include holistic approaches to health, such as occupational therapy and mental health therapy. The present study sought to evaluate the effectiveness of group therapy as it is conducted in a rural Oregon clinic using the Quadruple Aim to measure treatment outcomes (Bodenheimer, & Sinsky, 2014). Participants diagnosed with chronic pain and placed on …

Psychopathic Personality Traits In Students Entering Helping Professions, Sarah E. Gallup

Doctor of Psychology (PsyD)

Psychopathy is often misrepresented as a sign of criminality and deviance. However, current literature suggests that psychopaths make up approximately one-fifth of the general population. Some people use these characterological traits to their benefit in positions of leadership. In this study, students from a Christian university in the Pacific Northwest were selected to participate in a survey, based upon their chosen major (Business, Psychology, and Religion). It was hypothesized that Business students would have the highest total levels of psychopathy and religion majors would show the lowest levels of psychopathy. Since religion often serves as a protective factor, it is …

The Prevalence And Impact Of Dysmenorrhea In Young Women Within The United States, Annika Johnson Campbell

Doctor of Psychology (PsyD)

International research suggests dysmenorrhea is a common problem among young adult women, with a significant impact on their daily functioning. However, limited research has been conducted on dysmenorrhea in young women in the U.S. The current study analyzed the prevalence, impact, and treatment of dysmenorrhea among 976 young adult women living within the U.S. Using a cross-sectional design, a questionnaire based on previous literature was created. It was then distributed to women between the ages of 18-28 through university email and participant initiated social media distribution. The mean age of participants was 22.27, 85% endorsed dysmenorrhea. Seventy percent of women …

A Model Of Workload Assignment Preference And Its Effect On Performance, Productivity, And Stress, Christopher Winchester

Theses/Capstones/Creative Projects

The importance of employees within a firm has led to an increased need in maximizing performance and productivity, while also minimizing the stress levels of employees. This study provides insight into two types of workload assignment of (1) receiving a task all at once, and (2) receiving a task in incremental sections. It investigates how a subject’s workload assignment preference can impact performance, productivity, and stress levels. In addition, it also looks at the predictor variables of the Big Five personality traits, locus of control, tolerance for ambiguity, uncertainty orientation, and need for cognition to determine if workload assignment preference …

The Effects Of Ambient Temperature And Lighting Intensity On Wheel-Running Behavior In A Diurnal Rodent, The Nile Grass Rat (Arvicanthis Niloticus), Garrett M. Fogo, Alyssa M. Goodwin, Ohanes S. Khacherian, Brandi J. Ledbetter, Andrew J. Gall

Faculty Publications

Environmental conditions, such as the light-dark cycle and temperature, affect the display of circadian rhythmicity and locomotor activity patterns in mammals. Here, we tested the hypothesis that manipulating these environmental conditions would affect wheel-running activity patterns in a diurnal rodent, the Nile grass rat (Arvicanthis niloticus). Grass rats are diurnal in the field, however, a subset switch from a day-active pattern to a night-active pattern of activity after the introduction of a running wheel. The mechanism of this chronotype switch remains largely unknown. In the present study, grass rats were presented with running wheels in 12:12 light-dark conditions. First, subjects …

Steadfast Standards Or Fluctuating Fancies? Stability And Change In People’S Mate Criteria Over 27 Months, Carrie A. Bredow, Nicole Hames

Faculty Publications

Although research on mate preferences has been built on the assumption that the criteria people report at one point in time should predict their future partnering behavior, little is known about the temporal stability of people’s standards. Using survey data collected at four time points from 285 originally unmarried individuals, this study examined the rank-order, meanlevel, individual-level and ipsative stability of people’s mate criteria over 27 months. Overall, reported standards exhibited moderate to high baseline stability, with rank-order and ipsative estimates comparable to those reported for personality traits. At the same time, mean- and individual-level analyses revealed small, but significant, …

A Study Of Beluga (Delphinapterus Leucas) Vocal Ontogeny, Audra Elizabeth Ames

Dissertations

There is a shortage of literature regarding beluga (Delphinapterus leucas) vocal ontogeny, as presently, there has only been one published study on the vocal development of beluga calves, despite the value of ontogenetic studies for our understanding of sound-centered species. Here I offer the second longitudinal study of beluga vocal development. Using a calibrated digital hydrophone with a sampling rate of 256 kHz, I studied the vocal progression of a male beluga calf in early life. From his first day, the calf produced broadband pulse trains with upper frequency limits extending past the study’s Nyquist frequency (128 kHz); …

First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith

Master's Theses

Cetacean development is important for general comparative understanding and the implementation of informed husbandry policies. Due to the inaccessibility of many of these species in the wild, researchers can study managed care populations to better understand basic developmental patterns of cetaceans, as well as to improve husbandry policies for facility animals. However, no previous studies have attempted to observe the behavioral development of Pacific white-sided dolphins (Lagenorhyncus obliquidens). Eight beluga whale calves and four Pacific white-sided dolphin calves were observed for the first 30 days of life to determine the developmental trajectory of several typically monitored behaviors. The …

Organized Chaos: Daily Routines As A Potential Mechanism Linking Household Chaos And Child Behavior Problems, Kristy L. Larsen

Master's Theses

Children living in chaotic households exhibit more externalizing behaviors. Child externalizing behavior, exhibited as early as the toddler and preschool years, is a risk factor for later maladjustment. Understanding the mechanisms linking household chaos to early externalizing behaviors is important since those mechanisms could be targeted as a point of intervention. The primary aim of this study was to examine daily routines as a potential mediator of the relation between household chaos and both child externalizing behavior and bedtime resistant behavior. A secondary aim was to examine different levels of routines (family routines, general daily child routines, and specific bedtime …

A Comparison Of Social Learning In Domestic Canines, Beatrice Chenkin

Master's Theses

Domestic canines (Canis familiaris) provide a unique insight into the processes by which species can grow to cooperate efficiently with humans. Few studies have compared whether their behavior is more affected by humans or other canines. This study uses a two-action feeder (an apparatus that can be opened in one of two ways) to look into the methods of social learning they use and compares how they learn from humans vs. other canines. Sixty-four dogs from the Humane Society of varying backgrounds, ages, sexes, and reproductive statuses were tested on their ability to open the two-action feeder and the amount …

Exploring The Moderating Effects Of Aggression On The Relationship Between Negative Urgency And Suicidal Desire, Rachel L. Martin

Master's Theses

Suicide is a health concern with 44,965 deaths in 2016. Typical assessment of risk factors relies on self-report, which can be susceptible to underreporting. As such, non-face valid measures and innovative assessment approaches such as implicit association tests may help identify risk factors by eliminating conscious underreporting. The Interpersonal-Psychological Theory of Suicidal Behavior is an empirically supported theory hypothesizing why individuals die by suicide. The theory comprises three elements: thwarted belongingness, perceived burdensomeness, and capability for suicide. Thwarted belongingness and perceived burdensomeness have been found to be non-face valid measures and less susceptible to conscious underreporting. Objective measures, such as …

Social Skills Training And Generalization Of Skills In Children With Autism Spectrum Disorder, Brittany Wright

Honors Theses

The social deficits observed in individiuals with autism spectrum disorder (ASD) can often be improved with social skills training. The current study evaluated the effects of the Superheroes Social Skills training program which uses animated superheroes, video modeling, and comic books to teach social skills training. Three participants with ASD were trained in Conversation, Responding to Questions, and Body Basics over ten sessions, with sessions occurring twice a week in a non-school setting at the Arc of Southeast Mississippi. A multiple baseline across skills design across participants was used to examine the effects of the intervention on skill …

Perfectionism And Alcohol Use Outcomes In College Students: The Moderating Role Of Alcohol Protective Behavioral Strategies, Tiara Watson

Honors Theses

The purpose of this study was to evaluate the moderating role of alcohol-protective behavioral strategy (PBS) types (stopping/limiting drinking – SLD; manner of drinking – MOD; serious harm reduction – SHR) on the relationships adaptive and maladaptive perfectionism have with alcohol misuse and alcohol-related negative consequences. Participants included 526 traditional-aged college students (M_age = 19.77, 80.7% female, 60.2% Caucasian/White non-Hispanic) who reported alcohol consumption in the past thirty days and completed measures of perfectionism, typical weekly drinking, alcohol-related negative consequences, and PBS use. PBS-SHR moderated the relationships between adaptive perfectionism and typical weekly drinking such that the negative …

The Impact Of The United States Presidential Administration On African American College Students, Latisha Swygert

Honors Theses

It has been shown that college students of color do not share the same experiences as their Caucasian counterparts, with students of color experiencing higher levels of harassment and lower levels of perceived campus safety (Rankin & Reason, 2005). The purpose of this study was to explore the impact of the 2016 U.S. Presidential Election and the subsequent Trump administration on college students of color, specifically African American college students, and the psychological distress that may have been caused by the consequences of a shift in the national political climate. Participants were college students ages 18 to 54 who completed …

Religious Identity Influence On Ethnic Minority Youth Risky Behavior, Laquitta Simpson

Honors Theses

Previous studies have assessed religious identity in adolescents, showing that stronger religiosity correlates with lower levels of stress, better occupational and academic performances, and overall better well–being in adolescents and young adults (Koenig et al., 2001). There is also evidence of differences across races in how religiosity influences areas of adolescent behavior. The purpose of the current study is to identify the association between the strength of religiosity in White and Black at-risk youths and their involvement in risky behaviors. Data was gathered from teens aged 16-19 who are currently enrolled in a military-style residential program (n = 80); …

Contagious Or Not Contagious: Is That The Question? Evaluating The Effects Of Disease Contagion On Memory For Word Lists, Laura Pazos

Honors Theses

Researchers have suggested that individuals possess a disease-avoidance system designed to detect and remember potential sources of harmful pathogens, a system termed the behavioral immune system. Recently, Fernandes, Pandeirada, Soares, and Nairne (2017) reported an increase in memory for objects associated with individuals that are contaminated with a disease. My thesis extends this finding by examining whether disease-related memory benefits are due to the mere presence of a disease or whether the disease needs to be perceived as contagious and thereby threatening to facilitate memory. Two experiments, one between- and one within-subjects, were designed to test memory performance in the …

Direct Behavior Observations And Teachers' Ratings Of Internalizing Problem Behaviors, Lauren R. Parker

Honors Theses

Systematic direct observation is a commonly used method in schools to compile data on students' behavior in a naturalistic setting. Internalizing problem behaviors, behaviors such as social withdrawal, somatic complaints, and anxiousness, can lead to adverse consequences and have not, to the researchers' knowledge, been systematically observed in a classroom setting. Additionally, students have never been identified for intervention through direct observation. The researchers administered the Student Internalizing Behavior Screener (SIBS), which is a 7-item, teacher-completed, Likert-type scale which measures occurrences of internalizing problem behaviors. Once scores from the SIBS were calculated, students who scored at-risk were chosen for observation …

Vulnerable Narcissism, Difficulties In Emotion Regulation, And Relational Aggression In College Students, Shelby E. Caffarel

Honors Theses

Relational aggression is a form of aggressive behavior involving the intentional infliction of harm to the victim’s sense of belonging, reputation, or social relationships. Although most of the research on relational aggression has focused on children and early adolescents, there is evidence that it can be a serious problem for college students as well. Several predictors of relational aggression have been identified, but the mechanisms through which many of them operate is not sufficiently clear. The present study examined the relationship of vulnerable narcissism and difficulties in emotion regulation to relational aggression in a college student sample. It was expected …
