Neurocognitive Functioning In Adults With Trichotillomania: Predictors Of Treatment Response And Symptom Severity In A Randomized Control Trial, Kathryn E. Barber, Douglas W. Woods, Thilo Deckersbach, Christopher C. Bauer, Scott N. Compton, Michael P. Twohig, Emily J. Ricketts, Jordan Robinson, Stephen M. Saunders, Martin E. Franklin

Psychology Faculty Research and Publications

Trichotillomania (TTM) is associated with impairments in response inhibition and cognitive flexibility, but it is unclear how such impairments relate to treatment outcome. The present study examined pre-treatment response inhibition and cognitive flexibility as predictors of treatment outcome, change in these domains from pre-to post-treatment, and associations with TTM severity. Participants were drawn from a randomized controlled trial comparing acceptance-enhanced behavior therapy (AEBT) to psychoeducation and supportive therapy (PST) for TTM. Adults completed assessments at pre-treatment (n = 88) and following 12 weeks of treatment (n = 68). Response inhibition and cognitive flexibility were assessed using the Stop …

How Far Does The Apple Fall? Intergenerational Processes Underlying The Attainment Of Decent Work And Implications For Occupational Health And Well-Being, Baylor A. Graham

All Dissertations

Despite decades of progress spurred by the Decent Work Agenda (International Labor Organization, 1999), efforts to improve working conditions, ensure fair wages, and establish health and well-being as fundamental standards in employment practices continue to be sorely needed. The burden of inadequate decent work has demonstrated profound effects on individual health and well-being. However, the effects of inadequate decent work are rarely investigated over long periods of time and are entirely unexplored in relation to effects on children as they age and enter the workforce themselves. Accordingly, this dissertation investigated the intergenerational effects of decent work, extending beyond the immediate …

Identification And Validation Of A Measurement Of Emergency Physician Workload During End Of Shift Patient Handoffs, Steven Foster

All Dissertations

Recent increases in emergency physician (EP) workload have been identified as contributors to increased EP burnout, increased staff attrition, decreased patient safety, and increased patient admission rates. Patient handoffs have been extensively researched as critical points in patient care, with existing research primarily focusing on communication errors and interventions designed to standardize handoff communication protocols.

While end of shift handoffs in hospital emergency departments (EDs) intuitively represent a transfer of patient caseload from an outgoing EP to an incoming EP, there is a fundamental lack of literature examining how such handoffs contribute to EP workload, and a similar lack of …

Narratives Of Grief And Loss From The Children Who Lost A Parent On 9/11, Ryan Sliwak

Seton Hall University Dissertations and Theses (ETDs)

Limited research exists on the grief experiences of children who lost a parent on 9/11, particularly how these children evolve in their grief process, including their comprehension of the loss and their evolving attachment to the deceased parent (Kaplow et al., 2018; Alvis et al., 2022). Existing frameworks often assume post-traumatic reactions without fully considering the nuances of grief experiences for these children (Chemtob, 2007; Hoven, 2005).

Two research questions guided this study: (a) How does the pre-loss relationship with the parent influence the ongoing internal relationship with the deceased parent? (b) How does maintaining an internal relationship with the …

AI could be used in the AEC domain for advanced analytical and decision-making processes, while AR could be used for training, visualization, and remote collaboration.

In scenarios where construction site workers require expert guidance, these technologies could be helpful. …

Risk Perception, Diabetes Risk Knowledge, And Fatalism In Adults At Risk For Type 2 Diabetes: A Self-Determination Theory Perspective., Cassandra M. Gonzalez

Electronic Theses and Dissertations

Introduction: Rising rates of diabetes in the U.S. indicate an urgent need to explore and understand factors that elucidate individual diabetes risk. Research of fatalism, the belief that events are predetermined, suggests that fatalistic beliefs influence, shape, and potentially determine health behavior and decision-making. The Theory of Self-Determination posits the importance of motivation and competence in health behavior outcomes. The present study aimed to expand fatalism research by examining associations among fatalism and diabetes-related beliefs and knowledge, including perceived risk and risk knowledge, within the Self-Determination theoretical framework. Methods: Participants were 130 adults aged 26 to 64 without diabetes at …

Testing The Feasibility And Acceptability Of A Mindful Self-Compassion Group Workshop Among Individuals With Eating Disorders: A Pilot Study., Brenna Mary Williams

Electronic Theses and Dissertations

Background. Shame and self-criticism are mechanisms shown to influence eating disorders (EDs). Self-compassion has been theorized to target shame and self-criticism and is a protective factor against EDs. One intervention shown to increase self-compassion and reduce shame and self-criticism is the Mindful Self-Compassion program (MSC). However, MSC has yet to be tested among individuals with an ED diagnosis. The current study investigated the feasibility, acceptability, and preliminary outcomes of MSC delivered in a live, online format among individuals with an ED. Methods. Sixty-one participants completed baseline questionnaires measuring ED symptoms, trait self-compassion, self-criticism, and shame. Participants also answered questionnaires at …

4d Dynamic Spatial Brain Networks At Rest Linked To Cognition Show Atypical Variability And Coupling In Schizophrenia, Krishna Pusuluri, Zening Fu, Robyn Miller, Godfrey Pearlson, Peter Kochunov, Theo G M Van Erp, Armin Iraji, Vince D Calhoun

Faculty, Staff and Student Publications

Despite increasing interest in the dynamics of functional brain networks, most studies focus on the changing relationships over time between spatially static networks or regions. Here we propose an approach to study dynamic spatial brain networks in human resting state functional magnetic resonance imaging (rsfMRI) data and evaluate the temporal changes in the volumes of these 4D networks. Our results show significant volumetric coupling (i.e., synchronized shrinkage and growth) between networks during the scan, that we refer to as dynamic spatial network connectivity (dSNC). We find that several features of such dynamic spatial brain networks are associated with cognition, with …

Relationship Between Parenting Emotion Regulation, Parenting Style, And Child Emotion Regulation, Sydney R. Ward

All-Inclusive List of Electronic Theses and Dissertations

This study aimed to contribute to the existing literature by investigating parenting factors that contribute to child emotional regulation (ER). Prior research suggests that while emotion dysregulation is not part of current diagnostic criteria for attention deficit hyperactivity disorder (ADHD), children with ADHD often exhibit greater emotion regulation (ER) difficulties compared to their neurotypical peers. Research focused on parenting has found that parent’s ability to manage their emotions within a parenting context (parenting ER) as well as parenting styles (either positive or negative) are associated with child emotional regulation skills. However, previous research has not considered the influence of both …

The Lived Experiences Of Women Working In The Construction Industry As They Transition To Motherhood, Stacy Kolegraff

All-Inclusive List of Electronic Theses and Dissertations

This research aimed to understand women’s transition to motherhood in the North American construction industry. This study sought to understand what it means to be a woman working in the construction industry while making the transition to motherhood, experiences of re-entry into the workplace, emergent essential themes, and the way women interpret their career decisions and opportunities leading up to, during, and following their transition to motherhood. A qualitative research design was employed to analyze the complexities and dimensions of complex career decisions, and the phenomenological research method was used to understand the full extent of the problem. A total …

Digitally Connected, Evolutionarily Wired: An Evolutionary Mismatch Perspective On Digital Work, Mark Van Vugt, Stephen M. Colarelli, Norman P. Li

Research Collection School of Social Sciences

This paper makes the case for an evolutionary mismatch between digital work and the way human ancestors engaged in work. Psychological adaptations for producing things that early humans needed to survive and thrive, such as cognitive mechanisms for obtaining and processing food, toolmaking, and learning valuable working skills, evolved in the context of small networks of hunter–gatherers. These adaptations are central to understanding the significance of work in human evolution. Evolutionary mismatches operate when novel environments cue ancestral adaptations in ways that no longer provide adaptive benefits. We argue that digital work, although efficient and productive, is misaligned with some …

The Impact Of Perceived Administrative Support On Teacher Burnout, Madison L. Kelly

Electronic Theses and Dissertations

Teachers are crucial to many facets of life (Güneyli, 2012). Due to current occupational requirements and emotional demands, many educational professionals experience burnout (Roethler, 2021). Burnout occurs when daily occupational challenges overpower one's ability to maintain a healthy emotional state and meet professional demands (Roethler, 2021). Previous studies have been conducted on the levels of teacher stress and burnout (Agyapong et al., 2022; Chang, 2009; Lindqvist et al., 2021; Skaalvik & Skaalvik, 2021), while few studies explored the impact of administrative support and its contribution to burnout within the teacher population (Howard et al., 2017; Jacob, 2007; McCray-Davis, 2022; Tickle …

Factors Impacting Treatment Decisions In Caregivers Of Autistic Children, Tiffany Harris

Dissertations

Caregivers of autistic children are not only tasked with deciding upon various treatment options for their children’s symptoms but must also navigate the initial crisis that is experienced after receiving a diagnosis of ASD for their children (Blancher, 1984; Ellis, 1989). Leventhal’s Common Sense Model of Self-Regulation (the CSM; Leventhal et al., 1980) is a theoretical framework developed to understand the self-regulatory processes involved in adapting to and managing health threats and posits that cognitive and emotional illness perceptions influence illness outcomes through coping behaviors. This is the first study to examine all major components of the CSM (i.e., cognitive …

Do Social Support, Supervisory Feedback, And Job Stress Matter To An Employee’S Sense Of Ownership? Context In The Lodging Sector, Aladin M. Ibrahim, Zyra R. Cabrera, Rodin S. Pescuela

Journal of Global Hospitality and Tourism

In the face of intensified competition within the hospitality sector, exacerbated by the challenges of post-pandemic recovery, organizations are increasingly focused on re-engaging employees impacted by workforce reductions and retaining those who demonstrate a strong sense of attachment, care, and commitment to their workplace. These ownership behaviors are pivotal in fostering organizational stewardship and driving performance. However, the question arises: how can organizations cultivate and enhance these positive employee behaviors? This study investigates the influence of leader- and work-related factors, including social support, supervisory feedback, and job stress, on employees’ sense of ownership towards their organization. Employing a survey methodology, …

Stockholm Syndrome And Divorce-Related Decision Making Of The Abused Spouse, Simela Sidiropoulou

Walden Dissertations and Doctoral Studies

Knowledge of the challenges faced by domestic violence victims with Stockholm Syndrome (SS) symptoms during divorce was limited at the time of the current study. Previous findings supported frequent occurrence of doubts during divorce proceedings due to SS, with negative effects on victims’ well-being after separation. The purpose of this qualitative study was to investigate victims’ decision making processes affected by SS features. Data were collected from semistructured interviews with six mental health providers treating victims with SS symptoms during divorce proceedings. Interpretive phenomenological analysis was applied to identify vital experiences through the perspective of therapists. Analysis determined four themes. …

Trauma-Related Cognitions And Discrimination As Predictors Of Maladaptive Coping Among Marginalized Maltreated Youth, Shadie Burke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Maltreated youth are at an increased risk for engaging in direct or indirect self-injurious behavior to cope with the aftereffects of a traumatic event. These behaviors are often associated with negative health outcomes, substance use and premature death. Existing research proposes a link between child maltreatment and indirect self-harm but the mechanism into why this occurs is unclear. The present study examined two key research questions: (1) which specific trauma-related cognitions, sexual identity and cultural factors predict direct self-injurious behavior (previous suicide attempt(s) and NSSI) among marginalized maltreated youth?; and (2) which specific trauma-related cognitions, sexual identity and cultural factors …

Under The Neon Lights: Examining The Memories Of Las Vegas' Route 91 Harvest Music Festival, William B. Ridgway

UNLV Theses, Dissertations, Professional Papers, and Capstones

The aim of the current study was to identify patterns of meaning in the trauma narratives of Route 91 Harvest survivors. We undertook a thematic analysis to examine survivors’ narratives collected shortly after the event (i.e., within one month), allowing for a more in-depth understanding of what survivors tended to emphasize or gravitate toward when recalling the episode of mass violence that resulted in the deadliest mass shooting in modern American history. From the rich thematic content emerged a dominant theme of memory for contextual details—specifically, sensory-perceptual features, time, and space. Specifically, Route 91 Harvest survivors reported vivid sensory experiences, …

Self-Efficacy And Attitudes Associate With Undergraduates’ Library Research Intentions: A Theoretically-Grounded Investigation, Alex Pfundt, Laurel M. Peterson

Psychology Faculty Research and Scholarship

Undergraduates’ use of academic libraries is associated with academic achievement, but library research resources are underutilized, and little is known about what factors contribute to students’ use of these resources. A random sample of undergraduate students from a historically women’s college in the United States (N = 207; 59.2% white; 87.7% female or transfemale, 5.9% gender queer, 5.9% gender non-conforming, and 0.5% other gender) reported on their information literacy self-efficacy, attitudes toward research in undergraduate courses, and behavioral intentions to engage with library resources and services using an anonymous online questionnaire. Controlling for past library research and class year, …

Caring For A Family Member With Dementia: Collectivism And Individualism As Predictors Of Caregiver Burden, Christina Wawrowski

Dissertations

Caregiver burden, often associated with physical, emotional, and financial strain, is a significant concern for family members who are providing care to their loved ones. This study involved exploring the experiences of serving as a caregiver to a family member with dementia to better understand the relationship of collectivistic and individualistic orientations with perceived caregiver burden, while considering the level of social support and dementia severity. The research involved a quantitative approach, administering the Individualism and Collectivism Scale (Cultural Orientation Scale), the Caregiver Burden Inventory, the Functional Rating Scale, the Multidimensional Scale of Perceived Social Support, and a demographic survey …

Preschool Executive Control And Adolescent Dietary Outcomes: Highlighting The Role Of Context, Marla Lopez

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Research has identified executive control (EC) as an important predictor of dietary outcomes among youth. Executive control in preschool age has been shown to predict important outcomes across development for youth, indicating that good, foundational EC abilities are associated with successful development in later life. Dietary outcomes across adolescence, an important transitional period for establishing healthy eating behaviors, are understudied. Therefore, the current study sought to link two critical developmental periods, examining how preschool EC is associated with dietary trajectories across adolescence. Further, the study aimed to identify how contextual factors, specifically indices of socio-economic status and the home and …

Praying To Tiktok, Seeking The Self: How Rhetoric Reveals And Conceals The World’S Most Powerful Guru Of The Postindustrial Age, Samantha L. Gillespie-Hoffman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Imagine a world where the most powerful leader is a wellness guru that runs an elaborate church with millions of followers. The guru is so powerful that everyone believes they can read minds and make ordinary people rich and famous. The guru controls forms of communication, media channels, consumer tastes, and what people eat, drink, say, and even think. What if this guru was not human but actually an algorithm? Does this sound like the plot of a science fiction novel? I argue that this scenario is closer to reality than most will admit. In this project, readers encounter a …

Impact Of Placement Disruption On School Outcomes In Maltreated Youth, Mallory Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

School attendance is a crucial component of a youth’s ability to access resources and attain educational success. Maltreated youth are at increased risk for school absences, poor school performance, impairment in cognitive processes, and development of psychopathology. Disruption from their known systems (i.e., family, social, school) as a result of removal from home creates unique and substantial barriers for maltreated youth in attending and engaging in school. The present study used a sample of maltreated youth and binomial logistic regression analyses to determine if the number of lifetime placements impacts school outcome variables of school attendance, classroom behavior, and academic …

Relationships Between Psychopathology, Impulsivity, And Disordered Eating, Repairer Etuk

UNLV Theses, Dissertations, Professional Papers, and Capstones

Impulsivity is defined by behaviors that are often performed without foresight or consideration for consequences. For some individuals, impulsive behaviors are excessive or dysfunctional, and can become extremely problematic, ultimately leading to impairments in quality of life and lowered psychological functioning. Impulsivity is a multifaceted factor, comprising several different domains that have been explored in past studies (e.g., trait impulsivity, decision making, response inhibition). However, previous research shows that trait impulsivity in adults is consistently associated with several psychiatric problems including substance abuse, eating disorders, and compulsive sexual behaviors. To date, few studies have investigated impulsivity, compulsive sexual behavior. disordered …

The Phenomenon Of Creative Seeing As Discovered By Descriptive Experience Sampling: A Case Study, Amber Goto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Descriptive Experience Sampling (DES) studies have found that people without known mental health conditions occasionally describe visual experiences that are distortions of reality. DES calls such visual-perceptual-distortion experiences creative seeing. Typically, participants don't realize that their perceptions are distorted until they note their descriptions, at which time they notice (with surprise) the discrepancy.We describe "Rhea," a female adult (between 25 and 30 years old) DES volunteer participant. Her DES sampling happened to produce a high frequency of creative seeing; the degree of detail provided by DES allows us to describe the creative-seeing phenomenon with otherwise unobtainable detail. The creative seeing …

The Influence Of The Covid-19 Pandemic On Binge Eating In A Demographically Diverse Us Community Sample, Jessica H. Habashy

UNLV Theses, Dissertations, Professional Papers, and Capstones

The novel coronavirus pandemic (COVID-19) has had profound effects among many individuals with or at risk for eating disorders. The most common primary eating disorder is binge eating disorder which has uniquely reflected more similarities than differences among diverse populations compared to other eating disorder classifications. Considering the upsurge of prevalence rates of eating disorders during the pandemic, it is important to assess the rate of binge eating across the demographic strata to gain a better understanding of who is impacted and provide healing to those who are suffering. Screening for binge eating features across the United States (US) using …

Psychopathy And Moral Decision Making, Dimitra Kourtesi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the 1800s, psychopathy has been regarded as the absence of morality. The goal of our study was to explore whether psychopathic traits can affect the moral decision-making process in sacrificial moral dilemmas. Participants completed multiple self-report measures of psychopathic traits, utilitarian tendencies, and 16 sacrificial moral dilemma vignettes. After each hypothetical vignette, participants decided whether they believed it was morally right, permissible, and whether they behaviorally intended to sacrifice one person to save five people. Positive correlations emerged among all variables, which allowed us to perform a mediation analysis. Instrumental Harm – the idea of sacrificing one individual to …

The Role Of Cognitive Dysfunction In Late-Life Depression, Matthew Schurr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression is one of the most common psychiatric concerns in older adults. Because of the intersection of biological, emotional, social, and cognitive factors that are at play in depression, symptoms are often heterogeneous in presence and severity. In combination with the expected changes in cognitive abilities as one ages, late-life depression can be additive to these changes. The higher risks of neurodegenerative processes and vascular events in later life can cause, magnify, or accelerate cognitive decline. As such, individuals with late-life depression often present with a complex array of problems that can impact cognition and functioning, and thus complicate the …

Understanding The Role Of Discrimination In The Experience Of Traumatic Stress In Latine, Michelle Strong

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction. Research has found that low provider culture knowledge leads to poor mental health outcomes for Latine clients (Duke et al., 2011). Further, the 2017 APA Multicultural Guidelines emphasize the need for clinicians and researchers to conceptualize clinical and empirical data from a culturally competent lens, especially considering clinician and researcher bias while understanding a psychological phenomenon. Despite this, limited research exists categorizing the unique factors that affect mental health symptoms among Latine living in the United States (U.S.) especially as it pertains to trauma stress and discrimination (Marmot, 2005; Nadal, 2018). As such, the current study used meditational statistical …
