Implicit Beliefs About Anxiety And The Relationship With Competitive Anxiety Intensity And Direction, Luca M. Ziegler

Electronic Theses and Dissertations

During the Fall of 2021, 45% of male and 72% of female student-athletes reported overwhelming anxiety at least once a month (NCAA, 2021). In addition to affecting an individual’s well-being, anxiety may negatively impact athletic performance (Edwards & Hardy, 1996). To better understand the impact of anxiety on athletic performance and develop effective interventions, both the intensity and direction of symptoms experienced must be considered. Incremental beliefs have been shown to be related to desirable performance outcomes and increased well-being in various populations (Danthony et al., 2020; Dweck, 2008), and may provide an effective intervention to interpret anxiety as more …

Factors Associated With Intention To Disclose Concussive Symptoms In Active Duty Soldiers, Carly Beck

Electronic Theses and Dissertations

Background: Concussion disclosure is a heavily researched topic, and while previous literature has explored predictors of concussion disclosure in numerous populations, research within the active duty Soldier population is limited. This study further explored predictors of concussion disclosure to a medical professional or leadership in the active duty Solider population through the lens of the Theory of Planned Behavior. Methods: A cross-sectional electronic survey was distributed to 181 active duty Soldiers. Descriptive statistics were used to report frequency of high intention to disclose concussive symptoms among demographics, and a multivariate regression model was used to assess significant predictors of intention …

The Effect Of Motivational General-Mastery Imagery On Reaction Time Performance And Heart Rate, William J. Bean Jr.

Electronic Theses and Dissertations

Research suggests that imagery can reduce reaction time (Alikhani et al., 2001; Grouios, 1992; Hanshaw & Sukal, 2016; Iftikhar et al., 2018; Shanks & Cameron, 2000). Previous studies examining the imagery and reaction time relationship have almost exclusively focused on motor imagery. Additionally, a recent study by McNeil and colleagues (2019) concluded that imagery training improved decision time variables, but not overall reactive agility. Individuals may not be able to generate unpredictable stimuli during imagery. The purpose of this study was to examine the effects of motivational general-mastery (MG-M) imagery on reaction time and heart rate. Reaction time was measured …

Are Chronic Inflammatory Diseases Associated With Trauma Exposure And Gender? An Empirical Analysis Of Self-Reported Trauma And Health Histories Of Men And Women, Meghan Lacienski

Electronic Theses and Dissertations

A growing body of research indicates an association between trauma, inflammation, and chronic inflammatory disease; however, the mechanisms of this relationship are not fully understood, and the salience of potential risk factors, such as cumulative effects of trauma, trauma type, and gender, remain unclear. Trauma is associated with poor mental and physical health, such as PTSD, depression, and chronic inflammatory conditions, and this association may be stronger when certain risk factors are considered (Brody, Pratt, & Hughes, 2018; Groer, Kane, Williams, & Duffy, 2014; Husky, Mazure, & Kovess-Masfety, 2018; Kilpatrick et al., 2013). For example, sexual trauma and multiple traumatic …

The Mediation Of Perfectionism And Rumination On Mindfulness And Burnout In Collegiate Athletes, Nicholas S. Mcmillen

Electronic Theses and Dissertations

Several positive and negative sport-related experiences can occur throughout an athlete’s career, which can affect the continuation or termination of said career. Although research has associated sport participation with positive outcomes (e.g., increases in motivation, autonomy), there are also negative sport-related outcomes such as burnout (Akhrem & Gazdowska, 2016; Garcia, 2015). Specifically, burnout has been identified as a multidimensional construct that includes three dimensions. Furthermore, mindfulness has been studied to minimize the risk of experiencing burnout (Kabat-Zinn, 2003). While several studies have examined mediators between mindfulness and burnout, there has been a dearth of research on perfectionism and rumination as …

Treatment Choice Among Combat Veterans, Zachary Clayborne Dietrich

Electronic Theses and Dissertations

A plethora of research has investigated PTSD treatment outcomes among Veterans of foreign wars. However, research has suggested mixed treatment efficacy. Although investigations into factors that may help predict treatment outcomes are emerging, to date no study has evaluated treatment choice among Veteran populations. Previous treatment choice studies have yielded qualitative and quantitative information that can be useful in clinical decision-making. This study looks to build upon the treatment choice literature with combat Veterans to evaluate for underlining characteristics of cohorts that will help build upon existing knowledge. It has been suggested that treatment benefits Vietnam Era Veterans more than …

The Relationship Between Traumatic Events And Psychological Symptomatology And The Moderating Role Of Mentalization, Sean Fowler

Electronic Theses and Dissertations

Traumatic events can lead to a number of disparate psychological responses. Ranging from diagnosable psychological symptomatology to little or no distress, the outcomes of potentially traumatic events are difficult to narrow down. Research on individual differences has indicated the potential for a number of characteristics that influence the relationship between traumatic events and psychological well-being. Some researchers have proposed that one of these factors, an individual’s ability to mentalize, can influence the onset of psychological symptoms after a traumatic event. Mentalization is seen as one’s ability to maintain a sense of self, which enables understanding and differentiating between one’s own …

Improving The Inference Of Some Experiemtal Studies By Using Ranked Auxiliary Covariates, Rajai Jabrah

Electronic Theses and Dissertations

In many studies, the measurement of sampling units according to the response variable is costly or time consuming, however, it is possible to rank sampling units according to baseline auxiliary covariates, which are available, easily obtainable, and cost efficient. In these cases, when estimating the population mean, Ranked Set Sampling (RSS) can be a more efficient sampling method than the Simple Random Sampling (SRS) method. In this dissertation, we propose a modified approach of the RSS method to allocate units into an experimental study, aimed to compare two or more groups.

Ranked auxiliary covariates, which are typically correlated with the …

The Emotions, Coping And Social Support Perceived By Ncaa Division I Athletes During Concussion Recovery: A Qualitative Study, Paige Wells

Electronic Theses and Dissertations

Context: Concussed patients require an individualized assessment and treatment plan in order to improve the outcomes associated with their overall recovery. A new model has been created to explain the psychological response to sport concussion injury and rehabilitation process. This model highlights pre-injury and post-injury factors affecting the recovery process including emotions, coping and social support. Understanding the emotional disturbances, coping behaviors and social support available to concussed athletes may provide valuable information for the healthcare team in management and care for the concussed athlete.

Purpose: To identify and describe the emotions, coping mechanisms and social support perceived by Division …

Exercise Behavior Patterns In Emerging Adulthood: An Exploration Of Predictor Variables From Self-Determination Theory And Transtheoretical Model, Chad R. Johnson

Electronic Theses and Dissertations

During the transition from childhood to adulthood, young people establish patterns of behavior and make lifestyle choices that affect both their current and future health (NCHS, 2010). Emerging adulthood – a new conception of development for the period from the late teens through the twenties – focuses on individuals ages 18-25 who did not have a child, own a home, or have sufficient income to be fully independent (Arnett, 2000). Very little is known about social influence, motivational mediators, and motivation on exercise behavior within this developmental period. Therefore, the purpose of this study was to determine the influence of …
