Cognitive Performance In A Retired Nfl Population: Does Position Played And Racial Identity Impact Cognition?, Kimberly Chantelle Diah

Theses and Dissertations

Cognitive functioning is integral to everyday life as it involves mental processes crucial to everyday survival. Over the last decade, there has been increasing focus and controversy surrounding concussions sustained by players in popular contact sports. This attention has sparked national debates that continue to polarize both the sports and scientific communities on the long-standing neuroanatomical, cognitive, and psychiatric challenges that many retired NFL players experience later in life (Alosco et al., 2017; Hart et al., 2013). While studies have been conducted on the predictors of long-term neuropsychiatric and psychosocial outcomes following a traumatic brain injury, there are few studies …

Psychometric Analyses Of A Comprehensive Neuropsychological Battery For Retired Nfl Players, Kimberly Ethridge Fitzgibbon

Theses and Dissertations

This study examined psychometric properties of the NFL Concussion Battery used to examine neuropsychological functioning in retired NFL players who were part of the NFL’s concussion settlement. This battery assesses multiple areas of cognitive functioning; executive functioning, language, processing speed, attention and memory. The study included 117 participants who were male with at least 16 years of education. The sample was 75.9% African-American and average age was 47. All participants completed the entire battery and passed the majority of effort measures. Those that did not pass the majority of effort measures or complete the entire battery were excluded.

Psychometric Evaluation Of The Eyberg Child Behavior Inventory In An Ethnically Diverse Sample, Elizabeth Machado

Theses and Dissertations

This dissertation was designed to confirm the factor structure and to assess the psychometric functioning of the Eyberg Child Behavior Inventory (ECBI) in an ethnically diverse clinical sample using Confirmatory Factor Analysis (CFA) and Rasch modeling. The sample included 221 children and adolescents (72% male and 28% female) whose mothers completed the ECBI. Related to ethnicity, 43.4% of the sample was Hispanic American (HA), 41.2% was European American (EA), 12.2% was African American, and 3.2% identified as “other.”

Dimensionality of the ECBI was explored using CFAs and by evaluating model fit criteria. An Andrich Rating Scale Model was employed to …

Understanding The Distinctive Presentations Of Therapist Countertransference With Cluster B Personality Disorders, Sara Ashley Florence

Theses and Dissertations

Countertransference is one of several therapist variables that have been demonstrated to impact the quality of the therapeutic alliance. CT that is understood and managed by the therapist has the potential to serve as a tool in better understanding the patient, which puts the therapist in a better position to intervene therapeutically. CT that are emotionally charged can be more difficult to manage, and CT reactions tend to be especially emotionally intense when working with patients with Cluster B personality disorders (PDs). A better understanding of specific CT reactions to each Cluster B PD might aid in diagnosis and treatment …

The Effects Of Sleep Restriction On Biological, Psychological, And Neurocognitive Measures Of Health, Margaret S. Lorenzetti

Theses and Dissertations

Chronic sleep restriction impacts a significant proportion of the population, even though health is optimized following a minimum of seven hours of sleep. A preponderance of the literature examining the effects of sleep loss focuses on males and total sleep deprivation. Sleep restriction paradigms provide more ecological validity, as they are more consistent with sleep loss characterized in epidemiological studies. Moreover, enhancing the understanding of sleep loss among women, who are generally the gender most likely to encounter negative health as a result of poor sleep quality, is crucial. Thus, this investigation aimed to examine sleep restriction amongst a female …

Toward A Biopsychosocial Model Of Obesiy: Can Psychological Well-Being Be The Bridge To Integration?, Alexia Holovatyk

Theses and Dissertations

The complications associated with obesity are some of the most pressing health concerns facing the United States. At present, cardiovascular disease, stroke, and certain types of cancer are some of the leading causes of death, and researchers have cited obesity as one related factor (NIH, 2000). The topic of obesity has typically been approached through two seemingly contradictory lenses: The biomedical model that views obesity as a disease risk factor (e.g. Huxley, Mendis, Zheleznyakov, Reddy, & Chan, 2010) and the psychosocial model that considers the stigma associated with obesity to be more harmful than weight itself (e.g., Hatzenbuehler, Keyes, & …

Integrating Acceptance And Commitment Therapy Processes With Information-Processing Theory In Anxious Early Adolescents, Gilly Kahn

Theses and Dissertations

The social information-processing (I-P) model states that cognition assumes several cognitive steps (encoding, interpretation, response access, and selection). It has been shown that anxious youth display deficits or distortions at various stages of the social I-P model. In response to ambiguous situations, they show threat perception and interpretation biases, choose maladaptive responses, and engage in greater levels of avoidance than do non-anxious youth. Acceptance and Commitment Therapy (ACT) is an empirically-supported treatment for anxious youth. It aims to increase mindfulness, acceptance, and cognitive defusion, and to decrease experiential avoidance. The mechanisms explaining the effectiveness of ACT processes suggest that they …

A Novel Cognitive Stress Test For The Detection Of Early Alzheimer’S Disease In African Americans, Kimberly Capp

Theses and Dissertations

The U.S. population is currently undergoing a major demographic transition, with increasing racial and ethnic diversity of the older adult population. As the growing population of older adults advances in age, memory complaints are projected to increase in prevalence particularly among African Americans and present a challenge to clinicians who must differentiate between normal aging and progressive neurocognitive conditions (Celsis, 2000; Sherwin, 2000). As targeted therapeutic interventions and emerging therapies for AD are much more likely to be effective in the earlier stages of the disease (Loewenstein, Curiel, Duara & Buschke, 2017), early assessment and detection of AD, especially in …

Breaking Away: The Role Of Homeostatic Drive In Perpetuating Depression, Jonathan Tory Toole

Theses and Dissertations

The brain can be considered a complicated system of feedback mechanisms that maintain physiological homeostasis. Through psychological activity, neurochemicals act as homeostatic regulators. This study proposes that these components are part of a regulatory system that is capable of supporting multiple homeostatic regimes that, in turn, give rise to self-sustaining psychological behaviors. This project hypothesizes that such alternate regulatory programs may play a role in perpetuating psychological dysfunction. Interactions within and between components of the neurotransmitter network are represented as a set of discrete logic circuits. Neurotransmitter levels are linked to psychological constructs such as depression based on current literature. …

Exploration Of The Wechsler Memory Scale Fourth Edition (Wms-Iv) Designs Content And Spatial Memory Scales, Maya Pinjala

Theses and Dissertations

The Designs subtest was newly added as a measure of visual memory to the Wechsler Memory Scale, 4th edition (WMS-IV). This study examined this measure in a mixed clinical sample (n = 158). Specifically, the aim of the study was to evaluate the publishers’ claims that the Designs test assesses both visual content (“what”) and spatial (“where”) memory, as these functions are processed within distinct neurological systems. To date, no studies have specifically examined the individual Content and Spatial scores in relation to other neuropsychological variables. The purpose of this study was to gain a more comprehensive understanding of the …

Ptsd And Immunological Correlations Of Attention And Working Memory In Gulf War Illness, Mary Jeffrey

Theses and Dissertations

Gulf War Illness (GWI) impacts 25 to 32 percent of those deployed in the 1991 Gulf War (White et al., 2016) and includes symptoms related to fatigue and mood/neurological disturbances. Therefore, it is difficult to ascertain the influence of trauma exposure and chemical exposure when investigating neuropsychological symptoms. This cross-sectional study utilized a group of veterans with and without GWI (n=61) to investigate: 1) the unique impact that GWI has on a survey measure of attention and memory or the Paced Auditory Serial Addition Test (PASAT). We also investigated how PTSD symptoms, followed by fatigue levels, improved the GWI model …

Head-Impact-Related Outcomes By Position In Retired Nfl Football Players, Maria Cecilia Boix Braga

Theses and Dissertations

This study examined how repeated head-impact-related traumatic brain injury experienced by retired NFL players impacts their neuropsychological functioning, as well as whether player position was a significant factor in the impairment experienced. Participants (N=142) were selected from an archival database gathered through the NFL Concussion Settlement belonging to the Neuropsychology Assessment Center of Nova Southeastern University.

One-Sample T-Tests indicated that the combined sample and the Skilled players group demonstrated significant differences in all neuropsychological measures, while the Linemen and Skilled Linemen evidenced impairment in most areas except in visual-spatial and non-timed language measures. Two-way ANOVAs indicated player position and ethnicity …

The Second Shift.” Female Police Officers And The Struggle Of Work/Life Balance And Promotion, Ashlyn Decruise-Fortune

Theses and Dissertations

This study examined how women in law enforcement maintained a work-life balance with responsibilities such as motherhood, domestic responsibility and other care-taker roles. While there has been some research conducted on female police officers, much of the literature was outdated. Further, many of these studies focused on women’s performance and competence as police officers, and the associated burnout rate of female police officers. Very few studies examined the gender gaps in supervisory positions in relation to the Law Enforcement field within the United States, as well as the continued underrepresentation of women in Law Enforcement. Additionally, previous literature did not …

The Link Between Animal Cruelty And Violent Crime Victimization: An Assessment Of The Lifetime Impact Of Animal Cruelty On Secondary Victims, Amber Ahern

Theses and Dissertations

Animal cruelty and the secondary victimization of humans caused by animal cruelty are significant social problems. The dissertation presented a comparative research study on the developmental, psychological, and emotional symptomatology experienced by crime victims who had prior experiences with animal cruelty as a secondary victimization versus those who had not. Secondary victimization, as well as animal cruelty experiences, were operationally defined. This dissertation presented a broad literature review focusing on animal cruelty, its overall impact, and the link to other forms of criminality. This dissertation reviewed the importance of this line of research and possible implications for policy, future research, …

Perceptions Of Barriers In Prosecuting Human Trafficking Cases, Jennifer Nelms

Theses and Dissertations

Human trafficking is a world-wide problem with many barriers. Human trafficking cases are criminal but are also a violation of human rights. Human trafficking victims are lured from their homes based on the allusion from the trafficker of a better life. The victims are then beaten, forces to use drugs, and essentially broken. Once the victim is broken they are forced to perform sexual acts. Due to the initial promises and threats the victims endure, they also suffered from fear of trusting others especially law enforcement as well as other psychological issues similar to that of a domestic violence victim. …

An Exploration Of Task Independence For High School Students In A Self-Contained Classroom Using Structured Work Systems, Lorinda Rene Otto

Theses and Dissertations

This study investigated the effects of a method to support higher levels of independent performance and generalization of skills using a structured work system with a visual schedule when teaching online task completion skills to high school students with ASD and intellectual disabilities. Students with ASD and intellectual disabilities are typically deficient in independent skills. They often struggle to initiate and complete tasks on their own. By learning to complete tasks independently, high school students with ASD and intellectual disabilities gain essential life skills needed for employment. Structured work systems, along with visual schedules, have shown to be useful in …

Law Enforcement Officers As Victims Of Felonious Killings And Assaults: An Analysis Of The Predictors Of Lethality And The Likelihood Of Officer Assault Or Death, Gabriella Mercado

Theses and Dissertations

This study was designed to explore the predictors of lethality for the outcome of police officer assault with injury and felonious death. Recent news has focused on police brutality and their excessive use of force. Conversely, the inverse relationship has not received much focus. To explore the aforementioned relationship, data from the LEOKA program on 1,375 officers who were feloniously killed or assaulted with serious injury between the years of 2008 and 2017 were examined to determine the statistical significance between several predictor variables and the outcome variable.

Binary logistic regression was used to answer the research questions posed by …

Asd Training: Knowledge, Attitudes & Perceptions Of A South Georgia Police Officer, Heather Banks Mcneal

Theses and Dissertations

This study offered a preliminary look at the evidence to support the benefits of training South Georgia Police Officers on the phenomenon that is autism. Research suggested that there was limited experimental data available regarding why persons with ASD entered the criminal justice system, as well as how to manage them once they are there (Chovanec, 2013). Various regions of the United States embraced the importance of ASD training amongst their law enforcement officers; however, Georgia has only recently taken steps to do the same by the inclusion of a voluntary, online course regarding autism and de-escalation. Participants shared their …

Self-Service Technology In A Library System: An Examination Of Potential Library Member Adoption Of Self-Service Checkout At A Southeastern County Library System, Grace Keisha Phillips-Daley

Theses and Dissertations

This applied dissertation examined potential library member adoption of self-service technology (SST) in a southeastern county library system. The research framework of this study was based on the Technology Acceptance Model (TAM). More distinctively, this study explored the significance of motivation factors, to include both intrinsic and extrinsic factors, for choosing to use SST in a library environment as the reasonable effect of familiarity in influencing the possibility of its adoption.

The researcher used a non-probability sampling method to identify participants for the study. Edmonds and Kennedy (2013) suggested that surveys were primarily utilized to observe trends, personal attitudes, or …
