Effects Of Pressure-Based Virtual Reality Training On Mental Toughness In Athletes, Rylee J. Aspinwall

UNF Graduate Theses and Dissertations

Athletes often underperform in high-pressure situations due to challenges in emotional regulation rather than deficits in physical skill. Mental toughness, broadly defined as the ability to maintain performance under stress, is a key determinant of athletic success but remains difficult to train using traditional methods. Virtual reality (VR) offers a controlled and immersive environment for simulating competitive pressure; however, its application for training mental toughness remains limited. The present study examined the effects of pressure-based VR training on psychological and physiological responses in collegiate baseball and softball athletes. Participants completed up to eight VR training sessions under either high-pressure or …

Don't Crash Out: The Effects Of Personality And Social Support On Subjective Stress Responses And Heart Rate Variability, Nicholas Kilpatrick

UNF Graduate Theses and Dissertations

The present study examined the relationship between personality traits, physiological stress responses, and subjective stress during a social-evaluative stress task, as well as the potential mediating role of heart rate variability (HRV) and moderating role of imagined social support. Participants completed a laboratory-based modified Trier Social Stress Task while HRV was continuously recorded, and self-reported stress was assessed across task phases. Results indicated that neuroticism and protective self-monitoring were associated with higher levels of subjective stress, while acquisitive self-monitoring was associated with greater reductions in stress following the task. Neuroticism was also associated with greater increases in HRV during the …

Widowed And Wounded? Exploring The Health Impacts Of Adverse Childhood Experiences In Later Life Widowhood, Sierra Wickline

UNF Graduate Theses and Dissertations

Losing a spouse is considered one of the most stressful life events that disproportionately affect older individuals. Exposure to traumatic events at an early age can change the body’s response to subsequent stressors across the lifespan. These physical changes often impact people’s health. Utilizing data from the Health and Retirement Study, the current study aimed to investigate the link between: adverse childhood experiences (ACEs) and three indicators of health: inflammation (i.e., c-reactive protein [CRP], reflecting immune functioning), as well as self-reported depressive symptoms and physical health, among people who have lost a spouse. Participants included 97 widowed individuals aged 68 …

Social Support, Trauma And Neurophysiological Stress, Devon S. Glicken

UNF Graduate Theses and Dissertations

Traumatic life experiences and the prolonged effects of stress can negatively impact an individual’s mental and physical health. Hyperreactivity to acute stressors can often be seen in individuals with anxiety, depression, and suicidal ideations, conditions commonly observed with endocrine dysfunction. How do traumatic experiences, particularly experiences related to military affiliation, influence stress responses and feelings of burdensomeness and thwarted belongingness? This study predicted (1) that military-affiliated individuals (and those with PTSD symptomology and high perceived life stress) will have heightened neurophysiological responses to minor levels of acute stress compared to individuals without military-affiliations (and those without PTSD symptomology or high …

Development And Evaluation Of The Sex Positivity Inventory For Counselors, M. Ashley Burks, Jennifer Gerlach, Joshua C. Watson

Journal of Counseling Sexology & Sexual Wellness: Research, Practice, and Education

The purpose of the study was to clarify the definition of sex positivity and identify sex-positive attitudes, knowledge, and skills through the development and evaluation of the Sex Positivity Inventory for Counselors (SPI-C). The exploratory factor analysis supported a six-factor, 34-item scale, accounting for 32.9% of the variance within the study. The SPI-C had an excellent internal consistency of 0.96 and consisted of the following factors: 1) Procedural Sex Positivity, 2) Comfortability with Sexuality, 3) Perceived Sex Positivity, 4) Fundamental Sex Education, 5) Sexological Worldview, and 6) Unconditional Positive Sexual Regard. Implications for practice, counselor education, and supervision are discussed.

The Gut-Brain Axis: Investigating The Effects Of Diet, Physical Activity, And Prior Adversity On Anxiety Via Autonomic Nervous System, Jenna L. Pennella

UNF Graduate Theses and Dissertations

Previous literature has highlighted a bidirectional relationship between the gut and brain called the gut-brain axis (de Punder & Pruimboom, 2015; Hill et al., 2008; Leistner & Menke, 2020). The current study aimed to investigate directional relations between different stressors (e.g. poor diet, vigorous activity, and prior adversity) and anxiety and how interactions with gut issues and autonomic dysfunction may impact these relationships. Based on previous literature, we examined (a) physical activity and diet as moderators of stress and anxiety as well as stress and GI symptoms, (b) GI symptoms as a mediator between various predictors (i.e., diet, stress, physical …

A Pilot Study Of The Freeze Response: Physiological Markers Under Threat Versus Safety Video Conditions, Ula Mccarthy

UNF Graduate Theses and Dissertations

This pilot study examined physiological markers of the human freeze response during exposure to threat and safety-based video stimuli. The freeze response is an adaptive defense mechanism characterized by reduced heart rate and heightened sympathetic arousal (Roelofs, 2017; Hagenaars et al., 2014; Sagliano et al., 2014; Hermans et al., 2013). 20 university students were randomly assigned to view either a threatening or safety-based video clip while heart rate and electrodermal activity (EDA) were recorded using Biopac Bionomadix wireless systems. Trauma severity and PTSD symptomatology were assessed through validated self-report measures (BTQ; Schnurr et al., 1999), (PCL-5; Weathers et al., 2013). …

Retrospective Recall Of Food Parenting Practices During Childhood, Current Adult Health Outcomes, And Intuitive Eating, Katelyn Bretzel

UNF Graduate Theses and Dissertations

Emerging adulthood is a time of exploration, change, and emerging independence, which can make individuals vulnerable to health changes. Previous research demonstrates that food parenting practices (coercive control, structure, and autonomy support) during childhood may relate to health outcomes into adulthood. In the current study, it was hypothesized that intuitive eating during emerging adulthood would be associated with food parenting practices; with coercive control and structure practices hindering intuitive eating, while autonomy support encourages it. The current study tested these relationships further, utilizing retrospective reports of food parenting practices during childhood and examining their relation to intuitive eating, dietary quality, …

Teachers' Use Of Food Rewards In The Classroom Environment, Mckenna Fiore

UNF Graduate Theses and Dissertations

Food rewards are defined in terms of the value of a food to the individual at the time of ingestion. In classrooms, teachers may use food rewards to encourage academic achievement and appropriate classroom behavior (Hoffman et al., 2009). The use of unhealthy food rewards increases children’s desires for sweets and nonnutritive foods, which can pose risks for health and obesity-related outcomes, compared to healthier alternatives. Different characteristics, such as teaching style, classroom structure, teaching efficacy and teaching eating behavior, can be related to teacher’s use of different types of rewards. The goal of this study was to investigate the …

What Is Your Why? A Qualitative Study About Motivational Differences Of Latinos/Hispanics And African American/Black In A Computerized Cognitive Training Program To Prevent Alzheimer’S Disease, Lizbeth C. Vera Murillo

UNF Graduate Theses and Dissertations

Recruitment of diverse populations is a major barrier in advancing clinical research (Areán & Gallagher-Thompson, 1993; Areán & Alvidrez, 2003). The need to increase racial diversity is imperative due to the substantial growth of historically marginalized racial communities in the United States (Weinstein et al., 2017). Despite researchers’ efforts to increase racial/ethnic representation in clinical trials, there is still a lack of understanding of the best practices to recruit racial/ethnic minorities in clinical trials. The current study explores the qualitative motivations of why research participants (aged 65+ years old) volunteered for an Alzheimer’s Disease (AD) prevention clinical trial. Racial/ethnic differences …

Motivation Differences Of Males And Females In The Pact Study: An Exploratory Study, Maria E. Vander Meulen

UNF Graduate Theses and Dissertations

A cure for Alzheimer’s disease (AD) is not yet a reality, however, research on preventative interventions for AD has demonstrated promise. An issue this research has encountered and will continue to contend with is the recruitment of a generalizable sample. There are several randomized clinical trials (RCTs) in various disciplines that do not reach their target sample or must extend their recruitment period to reach their sample size. Challenges like this will aid in the delay of finding an AD prevention method. That impedes the help it could provide future generations. The current study explores research participants’ (2,617) open-ended responses …

Illness Stigma, Social Connectedness, And Health In People Living With Chronic Illness: A Structural Equation Model, Abigail Brooke Crawford

UNF Graduate Theses and Dissertations

The complexity of chronic or unexplained conditions may lead to potential stigma for those suffering long-term symptoms as they do not follow the expected pattern of recovery following diagnosis and treatment. Experiencing such illness-related stigma has potential for leading to a belongingness identity of detachment with implications for health across physical, social, and psychological dimensions. This study aimed to examine the relationship between stigma, social connection, mental health, physical health, and social functioning in a group of 231 participants with ongoing symptoms of chronic illness through structural equation modeling. The fit indices all suggest that the model reasonably fits the …

The Knights Of The Round Table: The Mediating Role Of Parental Self-Efficacy And Parental Stress In Explaining Family Mealtime Predicting Child Behavior In Mturk Families, Dea Zgjani

UNF Graduate Theses and Dissertations

The current study examined how shared family meals influence low negative behavior in children via parental perceived stress and parental self-efficacy in children between the age three and six. Using a parallel mediation analysis, multiple regression analyses were conducted for 204 participants. Results indicated parental perceived stress to be a mediator in the relationship of the structure of shared family mealtimes and negative child affectivity, in contrast parental self-efficacy was not. Additionally, interesting results were conveyed from exploratory Hypothesis 1. First, there were a total of 94 mothers and 102 fathers who completed the study. Significant correlations were depicted between …

In Sickness And In Health: Interactions Between Romantic Dyads, Power, And Health, Madisen Taylor Reasonover

UNF Graduate Theses and Dissertations

The current study applied the Actor-Partner Interdependence Model (Cook & Kenny, 2005) to assess influence in romantic dyads regarding health attitudes and behaviors (exercise, eating), and the moderating effects of gendered power. Associations between dyad similarity scores on health attitudes, health behaviors, and gendered relationship quality was also explored. Forty-five heterosexual romantic couples who were exclusively dating (72% White/Caucasian; age M = 22.3 years; relationship length M = 28.7 months) completed several questionnaires including: the Relationship Power Inventory – Overall (Farrell et al., 2015), the Perceived Relationship Quality Components Inventory (Fletcher et al., 2000), a modified Exercise Identity Scale (Anderson …

The Effect Of The Covid-19 Pandemic On How Social Media Use Influences Eating Disorders And Exercise Motivation, Abhilasha Kumar

UNF Graduate Theses and Dissertations

The COVID-19 pandemic has drastically impacted the life of every individual. Stay-at-home orders imposed to control the spread of the virus have only led to an increase in social media use to stay connected with others. College students were particularly affected by the measures put in place to control the spread of COVID-19 due to geographical, social, and economic changes (Aristovnik et al., 2020). The stress caused by these changes can increase eating disorder symptoms (Lacey et al., 1986) and exercise behaviors (Kim & McKenzie, 2014). The aim of the study is to observe the impact of the COVID-19 pandemic …

Investigating Body Dissatisfaction, Obesity, & Eating Pathology: African American Adolescent Girls & Mothers, Samantha Ronderos

UNF Graduate Theses and Dissertations

Body dissatisfaction is a globally prevalent issue among adolescents, particularly for those living in industrialized societies (Griffith et al., 2017). Body dissatisfaction is considered a central component of obesity intervention (Huh et at., 2011; Mitola et al., 2007) and eating disorder etiology (Kelly et al., 2005; Saunders & Frazier, 2016). It predominantly effects females and is commonly found among those with eating disorders and those who struggle with obesity or have higher BMI (Kelly et al., 2005; Saunders & Frazier, 2016). However this is contradicted in African American females, the majority of research has found low levels of body dissatisfaction, …

Insights From U.S. Deaf Patients: Interpreters’ Presence And Receptive Skills Matter In Patient-Centered Communication Care, Brenda S. Nicodemus, Lori Whynot, Poorna Kushalnagar

Journal of Interpretation

In the U.S., deaf individuals who use sign language have a legislated right to communication access in the healthcare system, which is often addressed through the provision of signed language interpreters. However, little is known about deaf patients’ perception of interpreter presence, its impact on their disclosure of medical information to physicians, and whether this perception affects their assessment of physicians’ patient-centered communication behaviors (PCC). A total of 811 deaf adults responded to questions on a bilingual ASL-English online survey about their experiences with interpreters and physicians. Logistic regression analysis was used to assess the relationship between deaf patients’ perception …

Exploring How Communal Motivations And Gender Norms Predict Sexual Health Practices, Courtney Olds

PANDION: The Osprey Journal of Research and Ideas

In the U.S., one in four women under 20 will experience unwanted pregnancy (NCPTU, 2017). Additionally, young adults (15-24) account for half of the new STI’s (CDC, 2017). Previous research has found that gender norms can have detrimental impacts on factors related to safe sex practices (e.g., condom use) such as perceptions of responsibility, self-efficacy and partner communication (Bertens, et al., 2008; Fantasia, et al., 2014; French & Holland, 2013; Huber & Eresek, 2011; Impett, et al., 2006; Noar, et. al, 2002). Conversely, findings have shown that communal (other-oriented) motivations is a predictor of condom use intentions, however, it has …

Self-Esteem And Disordered Eating In African American Youth, Carly Wagner, Samantha Ronderos, Dawn Witherspoon Phd

Showcase of Osprey Advancements in Research and Scholarship (SOARS)

Background: 30% of girls and 15% of boys engaging in disordered eating (DE) behaviors, such as irregular eating behaviors like bingeing, fasting, or purging (Campbell & Peebles, 2014). Low self-esteem has been found to have a significant impact on the development of mental health disorders (Stadelmann et al., 2017). Youth are susceptible to developing low self-esteem because of the developmental and social milestones that are experienced during this time (Chung et al., 2017). Although previous studies have found a relationship between DE and self-esteem, little research has focused on how self- esteem impacts DE in African Americans (AA).

Aims: To …

Imaginary Friends: The Effect Of Imagined Social Support On Subjective And Physiological Indicators Of Stress, Breana Bryant

UNF Undergraduate Capstone Projects and Honors Theses

Social support is known to help buffer the effects of stress (Uchino et al., 1996). However, in many situations social support is unavailable, and imagining social support may help to reduce the impact of stress. Although imagined physical touch has been shown to be an effective stress buffer, little research has compared it to other types of imagined support (Feldman et al., 2010). Additionally, women tend to seek emotional support, whereas men tend to seek tangible support, but it is unknown if imagining those types of support will reduce stress (Reevy & Maslach, 2001). To gain greater insight into these …

“The Power Of Love": The Role Of Sexual Communal Motivations And Relationship Power In Sexual Risk Taking, Robert Vincent Phillips

UNF Graduate Theses and Dissertations

College-age students are an at-risk population for an unplanned pregnancy. Current sexual health interventions focus on methods of preventing pregnancy but fail to address communal motivations (being oriented towards the needs of others) which are important in relationships. Current interventions are long and require an increased attention span which is less effective today because the current generation of adolescents has a decreased attention span. The present study develops a WISE sexual health intervention (a simple yet targeted intervention) that incorporates sexual communal motivations to reduce unplanned pregnancy in college-age students. It was hypothesized that participants will have increased condom use …

Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King

UNF Graduate Theses and Dissertations

When the body is faced with threat to life or limb, the autonomic nervous system works to overcome the danger – by either fight, flight, or freezing. While immobility may not appear to be the most logical solution, theories exist that it allows for judgement of the situation and preparation for action. This study investigated the stress response that military veterans, with or without post-traumatic stress disorder (PTSD), demonstrate when shown unpleasant images. Researchers wanted to determine the extent to which veterans would show freezing or immobile responses when under an unpleasant image condition. It was hypothesized that veterans who …

Development And Validation Of A Mindful Food Parenting Instrument To Assess The Relationship Between Parent Food Practices And Children’S Dietary Outcomes, Su-Nui Escobar

UNF Graduate Theses and Dissertations

American children’s diets are commonly recorded as deficient in nutrient rich foods such as vegetables, fruits, and whole grains. Such diets often exceed amounts of unhealthy items such as added sugars and sweetened beverages. In addition, 23% of children are considered overweight or obese. Mindfulness techniques in parents have been correlated with improved dietary outcomes in children and a healthier family eating environment.

The primary aim of this study was to develop and validate an instrument that reflects the theoretical framework drawn from current models of mindful eating, mindful parenting and mindful food parenting. The instrument is a practical tool …

An Examination Of Social Connectedness On Ptsd And Freezing In A Student Military Population, Jessica Marie Ledwith

UNF Graduate Theses and Dissertations

This study investigates the impact of social connectedness (SC) and post-traumatic stress disorder (PTSD) in a military college population, and their relation to physiological measures such as body sway, heart rate (HR), and heat rate variability (HRV). According to previous research, people with PTSD are more likely to exhibit a freezing response to affective images. In the present study, we explore the potential freezing response for military personnel at the levels of PTSD symptom groups and social connectedness. We also investigate the possible buffering effect social connectedness has on the outcome of PTSD and freezing. There was a total of …

Military Veteran Students Transition To Academic Life With Ptsd, Trauma, And Potential For Freezing Response., Alicia Marie Erchul

UNF Graduate Theses and Dissertations

The current study is the first known research to investigate the association of the freezing response with PTSD and traumatic stress in the military veteran student population. Current understanding of the freezing response are primarily based in comparative psychology, with some studies extending to human participants (Azevedo et al., 2005; Facchinetti et al., 2006; Hagenaars et al., 2012; Volchan et al., 2017). Models generally agree that the freezing response consists of reduced body sway with decreased heart rate (Porges, 2003, 2007; Hagenaars et al., 2014).

Thirty-eight military veteran students (n=38; 18 female; 20 male) with ages ranged from 19 to …

Food Insecurity And Children: How Food Insecurity Affects Mental Health In Children, Brianna L. Jordan

UNF Graduate Theses and Dissertations

Being without the financial means to have reliable access to enough food to sustain members of a household is known as Food Insecurity (FI; Gundersen, 2013). Previous research has linked FI to obesity and depression (Adams, Grummer-Strawn, & Chavez, 2003; Bronte-Tinkew, Zaslow, Capps, Horowitz, & Mcnamara, 2007; Huddleston-Casas, Charnigo, & Simmons, 2009; Kim & Frongillo, 2007). Although there have been findings about FI being related to depression and obesity, little research has used African Americans; even less research has used young adolescents as the target population. This study had five aims: 1) Observe the impact of FI on health, 2) …

Behavioral Factors Related To Weight Change In A Health Promotion And Weight Control Intervention, Bethany M. Hartsell

UNF Undergraduate Capstone Projects and Honors Theses

This study explored whether body weight was affected by certain lifestyle behaviors and if these behaviors were affected by a brief, self-directed weight control intervention. The behavioral factors assessed in this study included: meal regularity, fast-food eating, television viewing and eating/sedentary time, dietary modifications (e.g., portion control, reducing fat intake), self-monitoring (tracking diet and exercise), self-weighing, and physical activity. Participants were randomly assigned to intervention groups or a minimal contact control group. The intervention groups completed a 1-hour education session at baseline and received bi-weekly emails. Participants completed online questionnaires at baseline and 3 months, and body measurement sessions at …
