U.S. Military Veterans Transition To Two Midwest Universities: Post-Traumatic Stress Disorder, Moral Injury, And Academic Outcomes, Malychanh T. Bartlett

Dissertations

Abstract

Objective: To examine the association between posttraumatic stress disorder (PTSD) and moral injury (MI) and the extrinsic factors of the degree of negative patterns of healthy behaviors and negative experiences in an academic setting, the moderating effects of social support on PTSD and MI symptomatology, and the perception of academic success and positive perception of academic experience. Additionally, to examine the mediating effect of intrinsic factors (perceived academic experience) on academic outcomes objectively and subjectively.

Background: Student veterans as non-traditional students face challenges transitioning to the academic environment. Some have underlying mental and psychological complications of PTSD and MI, …

With A Little Help At Home: The Impact Of Romantic Partner Support On Daily Burnout And Workplace Incivility, Matthew Aplin-Houtz

Dissertations

With rude and discourteous encounters in the workplace becoming more common, Workplace incivility (WI) is at an all-time high. As such, workers experience levels of burnout from these negative social interactions. The literature concedes that the results of these interactions lead to mounting burnout, causing negative physical and emotional outcomes at the individual and organizational levels. Considering that the literature also supports that employees have the potential to recover from burnout symptoms through rest, obtaining the perception of control of their circumstances, and cognitive reframing, the time and activities a worker spends at home carry the potential for minimizing burnout …

Treatment Outcome From Cognitive Processing Therapy Examined Three Ways, Sophie Haven

Dissertations

Cognitive Processing Therapy (CPT), a Cognitive Behavioral Therapy for treating Post Traumatic Stress Disorder (PTSD), is an evidence-based treatment that has been demonstrated to be effective in treating PTSD. Nonetheless, CPT can have a high rate of treatment non-completion. Attrition from therapy has been operationally defined using multiple contrasting methods. Understanding attrition using a definition with the most clinical utility is essential to improving outcomes from efficacious treatments. Two clinically relevant definitions for attrition, session attendance and symptom improvement, are critical to understanding attrition. Combining information from both definitions, to create four separate groups, will provide more accurate information about …

Do Allyship And Motivation Influence Women’S Cognitive Functioning And Self-Regulation After Witnessing Sexism?, Christina Garasky

Dissertations

Prior research shows the effects of sexism can accumulate over time, resulting in severe negative, cognitive, affective, motivational, and physiological consequences for women; however, most research focuses on the consequences of being a direct target of sexism, and the cognitive and motivational consequences of being a witness of sexism have not yet been fully explored. Additionally, while it is thought that allyship can help mitigate the consequences of sexism, minimal research has tested this relationship. It was proposed that shifts in reactive approach motivation (RAM); aimed to protect against anxiety and negative affect, may direct attention away from goal-oriented behaviors, …

Self-Compassion And Experiential Avoidance: Potential Pathways To Posttraumatic Growth, Julia Sager

Dissertations

Social support has been identified as one of the most consistent predictors of posttraumatic growth (PTG). Although the role of social support in the process of PTG is informative, social support is intrinsically reliant on other people. Identifying internal, potentially malleable, factors that are associated with PTG is essential for developing preventative interventions to improve trauma-related outcomes and increase levels of PTG among trauma survivors. Internal processes such as self-compassion and experiential avoidance may promote, or interfere with, deliberate processing and the subsequent development of PTG; however, this has not yet been examined in the literature. Thus, the primary aims …

Gottman Processes And Couple Outcomes While Navigating Infertility, Clayton Brigance

Dissertations

Infertility remains one of the most difficult relational contexts for couples. However, some research suggests that some couples actually increase their overall satisfaction in their relationship through infertility due to a deeply shared emotional experience. To the knowledge of the author of this dissertation, no studies exist which explain how couples arrive at their relational outcomes through the experience of infertility. These studies within this dissertation add to the present literature by explaining how couples may arrive at their relational outcome through the lens of Gottman Method Couple Therapy (GMCT). For both studies presented here, 902 participants were recruited through …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Correlates Of Psychological Well-Being In Older Adults With Treatment-Resistant Depression, Selmi Kallmi

Dissertations

The purpose of this study was to examine the factors that are associated with psychological well-being in older adults with late-life depression and determine if social participation moderates and/or mediates these relationships. This dissertation study utilized secondary pre-treatment data collected from the “Optimum: Optimizing Depression Treatment in Older Adults” study (Cristancho et al. (2019). Community dwelling older adults (N = 369) were included if they currently met criteria for MDD, had failed at least two prior trials of MDD medication treatment, and were able to visit the study site to participate in cognitive and physical functioning assessments. Hierarchical multiple regressions …

Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan

Dissertations

Previous resting-state functional connectivity (rsFC) research has identified aberrant connectivity in several large brain networks in depression, including the default mode (DMN), frontoparietal (FPN), and salience networks (SN). Connectivity of these networks is also related to depressive symptom severity and is affected by cortisol levels. To our knowledge, this is the first study to investigate the effects of acute cortisol administration on rsFC of DMN, FPN, and SN in individuals varying in depression history and severity. We collected resting-state fMRI scans for 74 women with and without a history of depressive disorder after administration of cortisol and placebo using a …

Rethinking Binge Eating Disorder: Is Resource Depletion The Missing Link?, Laura Fewell

Dissertations

Binge eating disorder (BED), the most prevalent of the eating disorders, is associated with significant mental health impairments, high healthcare costs and utilization, and increased mortality. Yet little is known about the mechanisms involved in binge eating, and existing BED theories are incomplete. Scholars have recently suggested that resource depletion, or the state of reduced self-regulation abilities, may apply to BED, but no identified studies have experimentally examined this relationship. The purpose of the current study was to examine the role of resource depletion in binge eating behaviors. Ego anxiety, discomfort anxiety, and dietary restraint were also examined as potential …

Posttraumatic Stress Symptoms, Anger, And Substance Use As Risk Factors For Trauma Revictimization, Hannah E. Walker

Dissertations

Maltreatment survivors are at an increased risk for adult revictimization. Yet, existing work has specifically focused on sexual revictimization, and it is unclear what factors increase one’s risk for revictimization more broadly. Posttraumatic stress symptoms (PTSS), anger, and substance use have been identified as potential risk factors for sexual revictimization. Still, the role of these variables is ambiguous in the broader revictimization framework. There is also a lack of understanding regarding the roles of the DSM-5 posttraumatic stress disorder (PTSD) symptom clusters and revictimization. This study aims to: 1) examine the links between maltreatment and revictimization and three factors (i.e., …

What’S Religion Got To Do With It?: Differing Religiosity Domains’ Association With College Students’ Sexual Consent During First-Time Intercourse, Kaylee Richmond

Dissertations

Within the U.S., 36% of women and 17% of men report experiencing sexual assault (Smith et al., 2017). The absence of sexual consent is often regarded as a defining component of sexual assault (Beres, 2014); thus, a potential area to examine to decrease rates of perpetration and victimization. To date, there has been a lack of research on contextual factors that are likely related to sexual consent, with a general focus on external consent (i.e., verbal/behavioral indicators; Muehlenhard et al., 2016). The present study examined the role of a contextual factor, religiosity, on sexual consent processes during the context of …

Race, Masculinity, And Personality Development: Understanding The Black Male Experience In America, Veronica High

Dissertations

Although men from all racial backgrounds have several poor health outcomes, most of the research suggests that Black men have even worse health outcomes compared to White men (Bowman, 1989; Watkins & Neighbors, 2007; Williams, 2003). The majority of published research on masculinity, however, has primarily focused on samples of White men. The issue of how racism intersects with masculinity and its impact on Black men remains understudied and is a current area of focus in the field. The present study examined relationships between Black men on the cultural measures of masculinity and self-esteem, Dark Triad (narcissism, psychopathy, and Machiavellianism), …

Trauma And Alcohol/Substance Use: The Role Of Self-Regulation Flexibility, Saankari Anusha Challa

Dissertations

Despite a high comorbidity rate between trauma/PTSD and problematic alcohol/substance use, there is only a small body of work investigating moderators and mediators in this relationship. Few studies have examined the role of self-regulation, composed of coping and emotion regulation, in the context of PTSD and problematic substance use. Prior work has generally measured self-regulation categorically, with strategies labeled as maladaptive or adaptive, and therefore failing to account for the adaptiveness of the strategy in particular contexts. The present study is the only one to date to examine self-regulation flexibility in the relationship between posttraumatic symptoms (PTSS) and problematic alcohol/substance …

Sexual Minority Thriving: Bouncing Beyond Adversity, Debra Crawford

Dissertations

Sexual minority individuals continue to face prejudice and discrimination due to their sexual minority identity. However, despite these negative experiences, many sexual minority individuals display resilience and thrive. Most of the literature on sexual minorities focuses on negative aspects of identifying as a sexual minority, rather than the positive qualities that these individuals possess that allow them to persevere. In a sample of 303 sexual minorities, this dissertation contained two studies. Study one investigated if posttraumatic growth mediated the relationship between resilience and thriving and if identity pride and existential anxiety moderated the relationship between resilience and thriving in a …

Heart Rate Variability Following Treatment For Ptsd: Testing The Polyvagal Theory, Brittany F. Goodman

Dissertations

Posttraumatic stress disorder (PTSD) has been linked to lower heart rate variability (HRV), including measures of vagal tone. Treatments targeting the autonomic nervous system (ANS) have demonstrated efficacy in improving vagal tone, but it is less clear whether similar effects can also be achieved with cognitive therapies. The polyvagal theory has suggested that symptoms of social dysfunction are linked to vagal tone through a phylogenetically organized response to stress. HRV was collected during rest, reactivity (exposure to personalized trauma scripts), and recovery using a scripted imagery paradigm in female PTSD positive physical and sexual assault survivors (N = 41) …

Engaging Experts: Overcoming Trust In Risky Environments, Cynthia Goodwin-Sak

Dissertations

In business-to-business sales environments, sellers may choose to bring their go-to expert to a customer meeting, even when there is an expert available who may be more skilled in the product being discussed. The purpose of this study is to identify if an intervention of data, trust transference, ingroup identity, or a combination, influence the choice of expert a salesperson engages for a customer meeting. We tested this question through a series of vignettes and hierarchical linear modeling. The sample came from a US-based technology company, and salespeople in the United States.

We found that trust transference influenced both choice …

Rural Pregnant Women’S Experiences With Substance Use Disorder: A Qualitative Study, Cami Weber

Dissertations

Rural pregnant women with substance use disorder (SUD) are an understudied vulnerable population that often experiences poor pregnancy outcomes (Higgins et al., 2019; Jumah, 2016; Kramlich et al., 2018; Shaw et al., 2015). Despite the high prevalence and high burden associated with SUD, rural women are less likely than non-pregnant women to seek addiction treatment and complete an outpatient treatment program during pregnancy (Shaw et al., 2015). This study aimed to give voice to rural Missouri women with SUD. The research questions explored the life experiences and motivations for seeking treatment using a qualitative, descriptive research design with grounded theory …

Impact Of Aging Information On The Continuing Education Preferences Of Behavioral Health Clinicians, Nicholas Schmidt

Dissertations

The United States population is aging rapidly and the behavioral health workforce is ill-prepared to meet the concurrent rise in demand for services for older adults. Clinicians specializing in working with older adults make up a very small portion of providers and the majority of service provision falls on general practitioners. The discipline of counseling has emphasized multicultural competencies in training and practice but has not specified standards of competence for work with older adults; little is known about the interests and training preferences of Licensed Professional Counselors (LPCs). This study examined the impact of receiving foundational information about aging …

A Descriptive Study Of Health-Related Risks And Outcome Differences By Loneliness Status In A Sample Of Older Veterans, Rachael Beard

Dissertations

There is a need to understand the influences and outcomes related to loneliness in veterans living with complex illness. Patients require self-care to manage complications and exacerbations associated with complex illness. Deficits in self-care result in negative health outcomes and drive resource utilization upward. The identification of potential factors related to self-care is important. Loneliness may be one factor that influences patients’ ability and desire to care for themselves. Descriptive correlational design was used to evaluate loneliness both as a predictor and outcome in veterans admitted to the hospital for three complex respiratory illnesses (heart failure, chronic obstructive pulmonary disease, …

Regulation Of Self-Love, Kruti Surti

Dissertations

While the concept of self-love is well-known in today’s society, it remains unknown how self-love can be increased. Increasing self-love may help individuals decrease stress and promote well-being. The current study tested how self-love and pleasantness can be increased and whether anxiety levels and personality traits such as neuroticism and conscientiousness are associated with self-love increase. In this study, participants (N = 108; 86 women, 20 men, 1 gender queer, 1 other (not specified)) completed questionnaires related to self-compassion, self-efficacy, anxiety, and personality. Then, participants completed an online self-love regulation task in which they read prompts that encouraged them …

Barriers To Post-Secondary Success, Douglas Swanson, Najeana Henderson, Maritza Sloan

Dissertations

This study reviews factors that prior studies have identified or failed to consider as barriers to post-secondary success. The three main areas include academic success for Latinx students after high school, organizational systems and their impact on African-American students’ postsecondary readiness, and what workers think of their high school education with regards to career preparedness.

Five factors are identified as major barriers for Latinx students to continue in a higher education system. A survey of former students from Saint Louis, Missouri, and Dallas, Texas, metroplex area identified 56 Latinx students that participated in an initial survey. This led to a …

Moth To A Flame: An Investigation Of The Personality Traits And Early-Life Trauma Histories Of Women Who Have Survived Adult Relationships With Men With Pathological Narcissism, Michelle D. Roberts

Dissertations

Although emotional and psychological abuse, in addition to physical assault, are now commonly accepted as aspects of Intimate Partner Violence (IPV), narcissistic abuse as a subset of IPV is not widely recognized or understood. Due to the extremely debilitating, chronic mental health effects of narcissistic abuse (Bremner, 2008; Campbell, 2002; Yoon et al., 2009), this study sought to explore the experiences, personalities, early-life (childhood) trauma histories and mental health outcomes of heterosexual women who self-identify as having been in an adult romantic relationship with a man with pathological narcissism. Specifically, this study aimed to identify the nature and frequency of …

Uncertainty In The Context Of End-Of-Life Communication In Heart Failure, Caleb Pardue

Dissertations

End-of-life communication between patients, their family members, and healthcare providers is essential to quality care at the end-of-life. Advance care planning is increasingly utilized to facilitate end-of-life communication, but heart failure patients in particular face numerous challenges to achieving adequate end-of-life communication. Extant literature has highlighted the inherent uncertainty in heart failure as a barrier to end-of-life communication as well as the role of time perspective on the experience of heart failure patients, but little empirical research has been conducted to examine the impact of these constructs. The sample included 168 participants with heart failure who were recruited online through …

Searching For A “Home”: Examining The Experiences Of Confucian Asian College Students With Third Culture Kid Backgrounds, Yuima Mizutani

Dissertations

Third culture kids (TCKs) spend their childhood and adolescence outside of their home countries. Because of their unique backgrounds, TCKs and adult TCKs face challenges including identity development, low self-esteem, lack of connection with their home countries, posttraumatic stress disorder, depression, adjustment disorder, and others. Although the number of TCKs is increasing due to globalization, this population has been understudied. Moreover, most existing research has focused on TCKs in Western countries. Few researchers have studied Confucian Asian adult TCKs; that is, adult TCKs from China, Hong Kong, Singapore, Japan, South Korea, Taiwan, and others. Confucian Asian countries have collectivistic cultures …

Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd

Dissertations

Abstract

Up to 85% of nurses have reported exposure to incivility in the workplace (Hunt & Marini, 2012). The often-subtle nature of incivility toward nurses in a minority population may partially explain why it remains a problem. Healthcare organizations realize the need for civility to counter the high turnover rate, staff shortages, and low job satisfaction reported by nurses, but lack understanding of how nurses of a minority population perceive incivility and bullying. This study aimed to answer the research question how do nurses with minority representation experience incivility and bullying versus empowerment in the workplace? A descriptive phenomenological design …

Recognition Of Gender Microaggressions In The Workplace: The Case Of Predisposition And Propensity To Recognize, Alicia Ako-Brew

Dissertations

This study examined the individual factors that affect the recognition of gender microaggressions in the workplace. A total of 220 subjects participated in this study. Specifically, this study revealed how social dominance orientation, ambivalent sexism and gender discrimination perceptions toward women affect a third-party observer’s recognition of gender microaggressions perpetrated against women. In addition, this study examined the effect of role congruence on the propensity to recognize gender microaggressions. Role congruence stems from role congruity theory which posits that a woman in a leadership or masculine role will receive positive or negative evaluations based on the degree to which she …

Assessing A Cognitive Model Of Trauma-Related Sleep Disturbance, Rebecca Chesher

Dissertations

Sleep disturbance is a symptom of many mental health disorders that may negatively affect cognition and mood. Trauma-related sleep disturbance is a core reaction of traumatic stress and PTSD, similar to symptoms experienced by individuals with insomnia or other sleep-wake disorders. Although the cause and symptom progression of trauma-related sleep disturbance may be very different, research and clinical practice assess and treat it with measures and interventions designed for general insomnia. Using a cognitive model of insomnia modified for trauma-related sleep disturbance, the current study assessed the relations between select trauma and sleep variables within the proposed constructs of: 1) …

Exclusionary Beliefs, Multicultural Ideology, Empathy, And Perceived Threat: A Comprehensive Model Of Anti-Immigrant Prejudice, Reigna El-Yashruti

Dissertations

Despite the increased movement of people across national borders, anti-immigrant sentiment continues to pose challenges to immigrant mental health and disrupt intergroup relations. In the USA, where over 14% of the population is comprised of foreign-born individuals, immigrants continue to face prejudice from both the public and political administration. Intergroup Threat Theory (ITT) explains this prejudice as stemming from the perception that the out-group poses a threat to the cultural purity, economic stability, or physical safety of the in-group. Traits that promote group exclusion, such as perceived group superiority (i.e. Right-Wing Authoritarianism; RWA, Social Dominance Orientation; SDO, cultural dominance; CD) …

Psychological Factors Related To Physical Activity In Adult Congenital Heart Disease, Tyler Pendleton

Dissertations

Adults with congenital heart disease (ACHD) are a new and growing medical population. While medical interventions previously focused on reducing rates of infant mortality, current research suggests increased risk of premature mortality in ACHD may be partially due to acquired cardiovascular disease. One lifestyle intervention to reduce acquired cardiovascular risk is physical activity. Physical activity has been supported in the research as a safe, efficacious, and tolerable intervention for many ACHD; however, most patients do not engage in recommended levels of physical activity. The purpose of this study was to investigate psychological factors related to physical activity in ACHD. Participants …
