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.

T-test analyses …

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 …

Exploring The Professional Development Of Mft Students Enrolled In Equine Assisted Family Therapy Coursework: An Experiential Learning Modality, Natalie Rothman

Department of Family Therapy Dissertations and Applied Clinical Projects

Equine assisted activities have been utilized in various manners with multiple populations in therapeutic and educational environments. A graduate level marriage and family therapy program in South Florida is currently offering Equine Assisted Relational Learning (EARL) activities focused on teaching a specific sub-model of Equine Assisted Psychotherapy (EAP), known as Equine Assisted Family Therapy (EAFT). The experiential nature of EAP and EARL transforms abstract concepts such as thoughts and mannerisms into tangible experiences, as well as highlights behavioral patterns. The unique and innovative theoretical foundation of EAFT is being taught, demonstrated, and utilized to assist graduate level therapists with professional …

Sin Papeles: The Experiences Of Undocumented Central American Immigrants In The United States, Elizabeth Jarquin

Department of Family Therapy Dissertations and Applied Clinical Projects

In the United States, the topic of immigration represents a source of intense debate, which has escalated in recent years. Research indicates that Latinx immigrants are negatively impacted by current immigration policies— they are feeling afraid, angry, exhausted, defeated, overwhelmed, and concerned about themselves and their family (Castrellón, Rivarola, & López, 2017; Wray-Lake et al., 2018). This research, however, has largely neglected the Central American subgroup and the experiences of undocumented immigrants. The purpose of this study was to understand the experiences of undocumented Central American immigrants and their families within the current sociopolitical context. I utilized interpretative phenomenological analysis …

Conflict Style Is Not A Label: The Relationship Of Age, Education Level, Work Level, Reason For Assessment, And Time Between Assessments To Conflict Style Change, Michael P. Kelly

Department of Conflict Resolution Studies Theses and Dissertations

Organizations and research that are only measuring conflict style one time, are treating conflict style as a trait or label. However, conflict style can change over time, and with context. Even the circumstances around the conflict itself may impact how individuals handle conflict. This means that individuals may demonstrate different conflict styles in different circumstances. There is little research that explores the implications of individual conflict style change if measured at different times and in different circumstances. Nor is there much research that explores what factors may have an influence on conflict style change. This study explores whether conflict style …

Why Would I Want To Talk To Them? An Exploration Of Perceptions Of Talking Across Political Divides, Melinda Burrell

Department of Conflict Resolution Studies Theses and Dissertations

Americans are increasingly reluctant to talk across the political divide, a problematic situation for a system predicated on a citizenry exploring a marketplace of ideas and arriving at policy consensus. This study seeks to illuminate this problem through a qualitative, exploratory study around the research question of how conservatives and liberals experience communicating across the political divide. Results are examined through a research framework that first posits the benefit of deliberative democracy (Habermas, 1996), then identifies two major challenges to such – the tendency to avoid uncomfortable political discussions (Eliasoph, 1998) and the emotional, identity-driven process of polarization (Iyengar and …

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. …

The Social Media Machines: An Investigation Of The Effect Of Trust Moderated By Disinformation On Users’ Decision-Making Process, Zulma Valedon Westney

CCE Theses and Dissertations

Social media networking sites (SMNS) have become a popular communications medium where users share information, knowledge, and persuasion. In less than two decades, social media's (SM) dominance as a communication medium can't be disputed, for good or evil. Combined with the newly found immediacy and pervasiveness, these SM applications' persuasive power are useful weapons for organizations, angry customers, employees, actors, and activists bent on attacking or hacking other individuals, institutions, or systems. Consequently, SM has become the preferred default mechanism of news sources; however, users are unsure if the information gathered is true or false. According to the literature, SMNS …

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 …
