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 …

Investigating The Bed Nucleus Of The Stria Terminalis As A Predictor Of Posttraumatic Stress Disorder In Black Americans And The Moderating Effects Of Racial Discrimination, Kevin Petranu, E. Kate Webb, Carissa W. Tomas, Farah Harb, Lucas Torres, Terri A. Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Altered functioning of the bed nucleus of the stria terminalis (BNST) may play a critical role in the etiology of posttraumatic stress disorder (PTSD). Chronic stressors such as racial discrimination and lifetime trauma are associated with an increased risk for PTSD, but it is unknown whether they influence the relationship between BNST functioning and PTSD. We investigated acute post-trauma BNST resting-state functional connectivity (rsFC) as a predictor of future PTSD symptoms in Black trauma survivors. We also examined whether racial discrimination and lifetime trauma moderated the relationship between BNST rsFC and PTSD symptoms. Black adults (N = 95; 54.7% female; …

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 …

Co-Rumination, Psychological Inflexibility, And Internalizing Symptoms In Adolescence, John Parigger

Electronic Theses and Dissertations

Two risk factors for anxiety and depression in adolescence were examined: co-rumination, which occurs when friends excessively talk about problems; and psychological inflexibility, which occurs when one avoids negative feelings and fails to act on values. I hypothesized that psychological inflexibility would exacerbate the effect of co-rumination on adolescent anxiety and depression. Participants were 167 adolescents (Mage = 14.60 years, SD = 1.3; 65.7% cisgender males) who completed standard measures as part of an online survey. Results indicated no moderation effect, but there were main effects of co-rumination and psychological inflexibility on depression symptoms. Co-rumination may relate to …

Informed Consent Document Delivery: Effects On Appalachian Caregivers' Comprehension, Trust In Researchers, And Willingness To Participate, Tess A. Simpson

Electronic Theses and Dissertations

The purpose of the present study was to investigate whether altering an informed consent document (ICD), in ways that either promote or inhibit accessibility, would affect potential participants’ willingness to participate in a child development laboratory-based study. Specifically, I was interested in assessing the willingness to participate of historically underrepresented groups, especially Appalachian caregiver-child dyads. I altered three parameters of a previously approved and employed ICD to explore whether these parameters impacted Appalachian caregivers’ comprehension of the study, willingness to participate, and trust in the researchers. The manipulated parameters included reading level, utilization of illustrative pictures, and inclusion of text-to-speech …

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, …

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, …

The Presence Of Diversity Initiatives Leads To Increased Pro-White Hiring Decisions Among Conservatives, Zeinab A. Hachem, Tessa L. Dover

Psychology Faculty Publications and Presentations

Despite the push and pull between pro-diversity advocates and conservative resistance, most organizations have implemented diversity initiatives in an effort to promote equitable and fair organizational practices. Past work has shown that these diversity initiatives may not be as effective as expected and may instead result in unintended negative consequences for the very individuals they are meant to support. In three novel experiments (total N = 3,664), we investigated whether and when the presence of pro-diversity messages in organizational job recruitment materials might facilitate versus hinder the hiring of underrepresented racial minorities. Participant race and political ideology were also investigated …

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 …

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 …

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 …

Exploring The Everyday Inner Experience Of Grapheme-Color Synesthetes, Cody Michio Kaneshiro

UNLV Theses, Dissertations, Professional Papers, and Capstones

Synesthesia is a rare, multivariant condition where the stimulation of one sensory or cognitive sense induces extraordinary inner experiences. Grapheme-color synesthesia is a kind of synesthesia where the presentation of letters and/or numbers induce automatic, directly apprehended color phenomena within synesthetes (i.e., individuals with synesthesia). Despite synesthesia’s being defined by remarkable color experiences, first-person investigations that directly study synesthetes’ inner experience are rare. We used descriptive experience sampling (DES) to describe the everyday inner experience of six grapheme-color synesthetes, each sampled for from 6 to 14 sampling days. Our idiographic findings showed that the salient features of each individual participant’s …

Emotional Content In Working Memory Processes: An Fmri Study., Manal Zafar

Electronic Theses and Dissertations

Working memory (WM) is a dynamic system that processes and manipulates both goal-relevant and goal-irrelevant information, integral to higher-level cognition and executive control (Fujii, 2001; Nyberg & Erikkson, 2016). The processing and manipulation of representations is modulated by the affective nature of the information (Pessoa, 2009) such that negative information can either impair or enhance WM processing. WM impairments are seen commonly across clinical disorders such as depression, anxiety, PTSD and schizophrenia (Levens & Gotlib, 2010; Joorman et a., 2011; Brodziak et al., 2015). Specifically, negative information is known to have differential processing in WM compared to neutral and positive …

Relations Between Discrimination, Negative Attribution Style, Cortisol, And Depressive Symptoms In Adolescents., Hannah Widmer

Electronic Theses and Dissertations

The aim of our study was to integrate the chronic stressor of Perceived Everyday Discrimination (PED) into the Hopelessness Theory of Depression with a focus on the comorbidity between physical and mental health by way of depressive symptoms and cortisol in adolescents. Research has shown that cognitive diatheses mediate the relation between stress and depressive symptoms and cortisol predicts depression. We hypothesized that Negative Attribution Style (NAS) and cortisol would mediate the relation between PED and depressive symptoms. Altogether, 99 adolescents (mean age: 14.10 years, 36.4% female; 63.6% male; ethnicity: 2% Latinx; 98.2 % non-Latinx; race: 41.4% Black, 34.8% White, …

Everything And Nothing: Exploring The Connection Between Gender Microaggressions In The Family Of Origin And Intimate Adult Relationships, Stephanie Dizenzo-Priestley

Theses, Dissertations and Culminating Projects

Experiences with gender microaggressions have been shown to negatively impact mental health and self-esteem in women. Cisgender women are faced with pervasive gender microaggressions throughout life, including within their homes and families. This study sought to explore cisgender women’s experiences with gender microaggressions within two critical family systems, the family of origin and intimate adult relationships. Utilizing Postmodern Feminist Theory and Interpretive Phenomenological Analysis, three overarching themes were identified related to how cisgender women experience and make meaning of gender microaggressions: 1) Rigid Roles and Expectations for Women; 2) Impact of Power Dynamics; and 3) Identifying Pathways to Lasting Change. …

Exploring The Relationship Between Cognitive Inflexibility And Anxiety In Youth On The Autism Spectrum, Farah Mahmud

Theses, Dissertations and Culminating Projects

Anxiety symptoms are prevalent among autistic youth but frequently get overlooked due to issues of diagnostic overlap and atypical presentations of anxiety (Kerns et al., 2014; Wood & Gadow, 2010). Emerging literature suggests that cognitive differences specific to autism, such as cognitive inflexibility, may be associated with vulnerability of developing and maintain anxiety symptoms (Stark et al., 2021). Cognitive flexibility (CF), the ability to shift thinking and attention according to situational demands, is thought to be impaired in many autistic children, given the behavioral rigidity observed in this population (Geurts et al., 2009). However, further work is needed to tease …

The School Lunchroom As An Important Context In Children’S Social Development: The Link Between Lunchtime Peer Acceptance And Peer Victimization, Jake Callaway Steggerda

Graduate Theses and Dissertations

Steggerda et al. (2022a) found that children’s self-reported lunchtime peer acceptance was predictive of later experiences of peer victimization. These authors speculated that the link between lunchtime peer acceptance and peer victimization is mediated by children’s internalizing or externalizing problems. The current study adds to the field’s understanding of the link between children’s lunchtime peer acceptance and peer victimization by considering whether internalizing symptoms and externalizing problems are potential mediating variables. Participants were 659 children from 34 classrooms (M age 9.31 years, SD = 0.50; 50.7% female; 42.7% Hispanic/Latinx, 30.3% White, 10% Pacific Islander, 7.8% bi/multiracial, 2.2% American Indian, 2.2% …

Strategies For Misinformation Correction: Evidence For The Power Of Negation, Angel Houts

Graduate Theses and Dissertations

The current study investigated the effectiveness of different correction strategies for misinformation using a 2 (Source: no source, credible source) x 2 (Structure: negation, affirmation) within-subjects design with an additional control condition that had no corrections. Participants read 40 Twitter-like statements, which included 25 pieces of misinformation and 15 truthful statements, and rated their emotional responses on a Likert scale. After completing a distractor task, participants read additional Twitter-like statements across five different conditions. The first four conditions aimed to correct misinformation: negation with a credible source, negation without source, affirmation with a credible source, affirmation without source. The fifth …

Intellectual Humility And The Role Of Feedback On Children’S Intellectual Humility Expression, Christina M. Barnes

Graduate Theses and Dissertations

Intellectual Humility (IH) is the ability to recognize, acknowledge, and act, on the fallibility of one’s own knowledge (Porter et al., 2021). IH is associated with many positive outcomes including intellectual curiosity, tenacity, open-mindedness, and mastery behaviors (Leary, 2018; Porter & Schuman, 2017, Porter et al., 2020) leading some to believe IH is the promotion of IH as the next great educational virtue. Some scholars argue however, that too much IH can lead to Intellectual Servility which is associated with negative outcomes such as maladaptive perfectionism, need for cognitive closure, and less willingness to change a belief when presented with …

Measuring Listening Effort In Bilingual Listeners For Speech Perception In Noise, Sita Carraturo

Arts & Sciences Graduate Student Theses and Dissertations

Noise is a common impedance to easy and accurate speech understanding. In the presence of noise, speech processing mechanisms proceed with partial or ambiguous inputs, and listeners will engage additional cognitive resources to make sense of what they hear. The extent to which this is situation is affected by diminished exposure to a language is an understudied question, but one that is relevant to bilingual listeners. By virtue of using two or more languages, bilinguals have less exposure to any one language than monolinguals of that language do. This, in turn, may make language processing more effortful for them, particularly …

The Relationship Between Overparenting, Psychological Needs Satisfaction, And Alcohol Use On Risky Sexual Behavior, Melanie Prater

Master's Theses

Studies have shown college students to be vulnerable to negative outcomes, including engaging in risky alcohol use (Lewis et al., 2014; Kilwein & Looby, 2018; Cui et al., 2019) and risky sexual behavior (Dir et al, 2014; Trub & Stark, 2017; Kilwien & Looby, 2018). Understanding predictors and mediating variables associated with risky sexual behavior is one important means of improving prevention strategies. Parenting may be one variable associated with risky sex. Overparenting, a parenting style characterized by parental overinvolvement, has received recent attention due to its association with poor outcomes for adolescents and emerging adults, including an increased risk …

Psychophysiological Insights Into Child-Centered Play Therapy For Trauma: A Case Study, Kristi L. Perryman, Samantha Robinson, Timothy J. Schoonover, Julia Conroy

Counseling, Leadership, and Research Methods Faculty Publications and Presentations

Existing literature thoroughly reviews the detrimental consequences that adverse childhood experiences (ACEs) have physically, emotionally, neurobiologically, and financially. It is imperative to develop effective treatments that offer a sense of hope to children who have been impacted. The established relationship between high ACE scores and physiological hyperarousal due to emotional dysregulation is clear in the literature. This relationship indicates that taking psychophysiological measures may be an effective method of gauging the effectiveness of trauma treatments. This study measured the heart rate of a child who had experienced multiple ACEs, during 16 child-centered play therapy (CCPT) sessions, using the Empatica (E4) …

Utilising Discriminant Function Analysis (Dfa) For Classifying Osteoarthritis (Oa) Patients And Volunteers Based On Biomarker Concentration, Laura Jane Coleman, John L Byrne, Stuart Edwards, Rosemary O'Hara

Faculty, Staff and Student Publications

Osteoarthritis (OA) is a degenerative joint disease characterised by the breakdown of cartilage, causing pain, stiffness, and limited movement. Early diagnosis is crucial for effective management but remains challenging due to non-specific early symptoms. This study explores the application of Discriminant Function Analysis (DFA) to classify OA patients and healthy volunteers based on biomarker concentrations of Interleukin-6 (IL-6), Tumour necrosis factor-alpha (TNF-α), and Myeloperoxidase (MPO). DFA was employed to analyse biomarker data from 86 participants (58 patients, 28 volunteers) to evaluate the discriminatory power of these biomarkers in predicting OA. Significant differences were observed in MPO and TNF-α levels between …

4d Dynamic Spatial Brain Networks At Rest Linked To Cognition Show Atypical Variability And Coupling In Schizophrenia, Peter Kochunov

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 …

Mathematical Anxiety In The Turkish Context: Mathematical Experiences Of High School Students, Vahap Yorgun, Serdal Mert

Journal of Humanistic Mathematics

Although a handful of studies have investigated the prevalence of math anx- iety among Turkish school children and its relationship with several variables like attitudes toward math, gender, self-efficacy, parental style, there is as of now no study focusing on development psychological interventions to cope with math anxiety. Most of the extant studies use quantitative approaches, but in order to develop intervention programs, researchers need to know how math anxiety develops, what kinds of personal variables or factors take place in this process, and what kind of emotional and cognitive reactions hold by students about math. Thus in our research, …

Emailed Prompt Package To Increase Alternative School Educators’ Use Of Behavior Specific Praise, Chelsea Johnson

Dissertations

Alternative school educators are often placed in alternative education settings with minimal training or support to manage disruptive behaviors in the classroom. To combat this, school-based consultation may be provided to assist alternative school educators with classroom management strategies. However, face-to-face consultation may be limited due to the numerous responsibilities placed on school-based consultants. Behavior specific praise (BSP) is a strategy that is recommended, but often provided at low rates. To address these barriers, previous literature has examined the use of emailed prompts to increase treatment integrity, feasibility, and acceptability of a variety of evidence-based interventions. A concurrent multiple baseline …
