Identifying Trauma Related Predictors Of Dissociation In Maltreated Youth, Amanda L. Mraz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Maltreated youth who experience traumatic dissociation are at an increased risk for various psychopathological difficulties. Much is still unknown about the machinations behind experiences of dissociation post-trauma. This study aimed to identify variables that place maltreated youth at risk for experiencing traumatic dissociation (e.g., dissociative amnesia, absorption and imaginative involvement, passive influence, depersonalization and derealization, and total adolescent dissociative experiences symptoms (A-DES)). Investigatory variables included demographic (e.g., age, gender, and racial identity), cognitive (e.g., resiliency and posttraumatic cognitions), and psychological (e.g., posttraumatic stress disorder symptoms (PTSD) and anxiety) factors. Classification and regression tree (CART) analysis was utilized to observe the …

The Relationship Between Psychopathy And Sexism Across Self-Report, Vignette, And Novel Dialogue Tree Tasks, Arianne Fisher

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychopathy is a personality construct consisting of a number of traits often associated with what many consider to be the “dark side” of personality. Multiple models and associated measurement tools have been created in an attempt to conceptualize psychopathy, but the field has not reached a consensus in its definition of this construct at this time. Across models, psychopathy is associated with a number of negative attitudes and behaviors, including various forms of prejudice. The relationship between psychopathy and one form of prejudice has not been examined, constituting a serious gap in the literature. This form of prejudice is ambivalent …

Examining The Factor Structures Of The Erq-Ca, Rcads, And Rsca To Identify Unique Predictors Of Ptsd Symptom Clusters In Maltreated Youth, Amanda N. Howard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Youth who have experienced maltreatment have a higher risk of developing posttraumatic disorder (PTSD), which is associated with poorer mental and behavioral health outcomes including emotion dysregulation, anxiety, depression, and lower resiliency. At present, the literature largely focuses on youth who have experienced general trauma or PTSD symptoms, while maltreated youth are vastly understudied. The present investigation was the first study to date to examine the factor structures of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA), the Revised Child Anxiety and Depression Scale (RCADS), and the Resiliency Scale for Children and Adolescents (RSCA) in a sample of maltreated …

Examination Of Performance Validity And The Relationship To Cognition And Symptoms In Schizophrenia Spectrum Disorders, Erick A. Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Approximately one-in-five individuals with psychotic disorders (i.e., schizophrenia spectrum disorders [SSD]) fail performance validity indicators (PVIs) during neurocognitive testing. Ensuring the validity of neurocognitive test results is necessary if the test scores are to be of use for diagnostic consideration, intervention selection and planning, predicting outcomes, and following changes in cognition over time in response to intervention, spontaneous recovery, or disease progression. PVIs are designed to require only a minimum level of engagement with the evaluation, which means nearly everyone is expected to “pass,” even those with moderate to severe brain damage. Traditional interpretations of PVI failure suggest a noncredible …

Identifying Clinical Profiles In A Community Sample Of Youth With Selective Mutism, Melanie Rede

UNLV Theses, Dissertations, Professional Papers, and Capstones

Selective mutism (SM) refers to a consistent failure to speak in social situations that have an expectation for speaking, despite fluent speech in other situations (American Psychiatric Association, 2013). Recent researchers describe SM as a heterogeneous disorder not always characterized by anxiety (Driessen et al., 2020). Specifically, some have argued that SM may be better explained as a neurodevelopmental rather than an anxiety disorder (Kearney & Rede, 2021). The aim of the present study was to find unique classes for anxiety, oppositional, and communication difficulties among youth with SM. Participants included 129 caregivers of youth with SM aged 6–14 years …

Offender Reintegration In Nevada: A Longitudinal Study Focusing On Transitional Challenges, Reentry Capital, And Recidivism, Carolyn S. Willis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Offender reintegration (reentry) depends on offender motivation, public policies, community efforts, and resources provided through government and nonprofit sectors. As individuals are released from incarceration and reintegrate into the community, they are often dependent on resources provided by different service providers and the community. The role of the community is crucial as resources are oftentimes not accessible. Lack of employment and housing, mental health issues, substance abuse, and the inability to reestablish personal relationships diminish the prospects of successful reintegration and increase the chances of reincarceration. Reentry capital delivered through community-based programs addresses the transitional issues justice-impacted individuals encounter post-incarceration. …

Cultural Mechanism Of Mothers' Perceptions Of Youth Psychopathology, Yen-Ling Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cross-cultural research systematically identifies variations in cultural practices, meanings, and responses across different cultural groups. For example, psychiatric symptoms vary in their salience and degree to which they are reported across cultures. Cultural differences in causal attributions likely lead to differences in an individual’s help-seeking intention. However, there are limitations in previous cross-cultural studies about perceptions of psychopathology, including not measuring impairment level and parental distress, as well as the problematic use of categorical variables as predictors. To overcome limitations in previous work, the current project examined the cultural mechanism of mothers’ perceptions of externalizing and internalizing psychopathology in youth. …

Clinical Utility Of The Substance Use Items Of The Sport Interference Checklist In Collegiate Athletes, Igor Kowal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Collegiate sports are growing in popularity (National Collegiate Athletic Association, 2022) and pressure to perform (van Raalte & Posteher, 2019); leading to difficulties in collegiate athletes’ mental health (Rice et al., 2016), particularly in regard to increased substance use (Wilson et al., 2021). Current literature demonstrates that existing substance use assessments are most likely not answered truthfully by athletes (van den Berg et al., 2018), are not applicable to real-world contexts, can be intrusive, and are expensive to administer. In the current study, psychometric properties of items from a self-report measure of substance use interference with sport training and competition …

Measurement Invariance Of Impact In Bilingual And Monolingual High School Athletes, Hana Cecilia Kuwabara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Given the reported negative consequences of sport related concussion (SRC), establishing the validity of concussion management tools is essential if they are used to determine the severity of concussion, track recovery or decline, implement effective interventions, and assist in return-to-play decision making. Previous research has found cognitive and symptoms differences on ImPACT, the most widely used SRC assessment measure, between monolingual and bilingual student athletes. Before further investigation of these differences can occur, measurement invariance of ImPACT must be established to ensure that differences are not attributable to measurement error. The current study has two aims: 1) to replicate a …

The Psychopathology Circumplex+: A Novel Conceptualization Of Psychopathology And Associated Measure, Edward A. Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fearless Dominance (FD) and Impulsive Antisociality (IA) are two personality traits often used in the study of psychopathic personality. FD is characterized by a lack of empathy, resilience to stress, and social potency, while IA is marked by impulsivity, selfishness, and manipulativeness. The current trio of studies sought to expand the use of FD and IA to assess psychopathology more generally. Study 1 consisted of a meta-analysis of all the relationships between FD/IA and various forms of psychopathology. Results affirmed that FD and IA each correlate with a variety of different psychological disorders, each to varying degrees of magnitude, but …

Initial Development And Psychometric Evaluation Of The Mental Health Optimization Checklist (Mhoc), Raymond E. López

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: The Mental Health Optimization Checklist (MHOC) is a proposed measure which utilizes the theory of optimization science to improve mental health outcomes. Psychopathology is typically viewed dichotomously (i.e., does or does not have a disorder) or through cut-off criterion (i.e., 4 out of 5 symptoms, total scores), whereas optimization views psychopathology on a continuum on which patients can optimize factors impacting their mental health. Optimization theory is important for reducing stigma around mental health treatment and the MHOC offers itself as an informative psycho-diagnostic tool.

Methods: An undergraduate student sample (n = 682) completed the MHOC and the Symptom …

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

Gender Differences In Internalizing Problems And Everyday Behaviors Associated With Executive Function In Children And Adolescents With Autism Spectrum Disorder, Hiroko Mullner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Many children with autism spectrum disorder (ASD) experience internalizing problems, and there was evidence suggesting that poor executive function (EF) predicted their internalizing problems. However, this association was primarily found in studies with male children with ASD. Therefore, the present study aimed to investigate gender differences in internalizing problems and everyday EF in ASD children (age 5-15) and examined the associations between internalizing problems and everyday EF.Method: This study examined neuropsychological assessment data of ASD children without intellectual disability. The study consisted of two groups: 1. ASD boys (n = 44), 2. ASD girls (n = 15). The study …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Telehealth In Patients With Type 2 Diabetes Mellitus, Saghi Nassrouie

UNLV Theses, Dissertations, Professional Papers, and Capstones

Description: Type 2 diabetes mellitus (DM2) is an epidemic that has many factors involved in its management to maintain control. Patients with DM2 require routine evaluations and blood work to provide comprehensive care. COVID-19 caused major shifts in traditional care which sparked an increase in the utilization of technology like telehealth. Telehealth can be an effective tool used to manage diabetes and help attain better glucose control, but its effectiveness during the COVID-19 pandemic warrants further investigation.Purpose: The purpose of this project was to determine if telehealth visits were more effective in reducing Hemoglobin A1c (HbA1c) in adult patients with …

Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

University-level language and second-language classrooms typically use general rules of thumb to teach grammar without considering its conceptual aspects and cultural origins. These general rules of thumb are normally taught using a communicative approach to language teaching which typically places little emphasis on immediate corrective feedback and learner development. Most assessments are static in nature and focus on right and wrong answers rather than their origins (i.e., learner development and microgenesis). The lack of corrective feedback and lack of considering affective factors have the potential to negatively influence language acquisition in terms of motivation and self-efficacy. In addition, foreign language …

Rock Or Relic? Lithic Technology And Social Life In The Mimbres Mogollon Region Of Southwestern New Mexico, Jeffrey Dylan Clark Person

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research project investigates stone tool technology at pithouse and pueblo sites in the Mimbres Mogollon region of southwestern New Mexico. Starting around AD 550, people in this area were shifting from mobile foragers who moved in seasonal rounds to sedentary village farmers. This process of subsistence change sparked further changes in material culture and social organization across the Mimbres region. The dissertation focuses on lithic debitage, the stone flakes and rock shatter that resulted from reducing stone cores into usable cutting and scraping tools. Debitage from three Mimbres sites, the Harris site, La Gila Encantada, and Elk Ridge were …

The Role Of Small Puebloan Architectural Sites On The Southern Shivwits Plateau, William M. Willis

UNLV Theses, Dissertations, Professional Papers, and Capstones

This work concerns itself with the Virgin Branch Pueblo of the southern Shivwits Plateau. Within their settlement systems lies considerable variation in terms of architectural sites. The smallest of these sites are often referred to as fieldhouses, a term that has distinct meaning within the archaeological discourse of the American Southwest. Fieldhouses are seasonally occupied structures used by Puebloan people during the agricultural growing season. They arise out of the necessity of land tenure systems that evolve in response to growing competition for arable land in the face of population pressure and finite resources. This research finds that the small …

Musculoskeletal Injury Concealment In The Reserve Officers’ Training Corps, Joshua D. Wooldridge

UNLV Theses, Dissertations, Professional Papers, and Capstones

INTRODUCTION: Among service members, musculoskeletal injuries threaten military readiness and place a substantial burden on medical and financial resources. While musculoskeletal injuries (MSKIs) are a leading threat to military readiness, service members’ unwillingness to seek care constrains current prevention and surveillance efforts. A growing body of evidence shows US service members conceal a large proportion of injuries, especially in training environments. The Reserve Officers’ Training Corps is a critical training environment for future US military commissioned officers. Reserve Officers’ Training Corps (ROTC) is the largest commissioning source of new officers for the US military. ROTC cadets are college students concurrently …

The Transaction Costs Of Federal Environmental Policy Changes: The Effects Of The Temporary Covid-19 Cwa Rollback On Local Water Systems, Jesse Lee Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

An institutional dilemma exists between the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). US surface waters are protected from point-source pollution by the CWA. Community Water Systems (CWSs) that draw from these surface waters for potable purposes are required to treat that water to a level that meets SDWA health standards. Therefore, decreases in CWA regulations could lead to surface water quality declines and, thus, higher SDWA compliance costs for CWSs. This area of inquiry has become increasingly relevant due to Trump-era executive actions to try to decrease the federal government's role in multiple environmental policies, …

The Impact Of Local Broadband Access On High School Graduation Rates, Eugen Brazdil

UNLV Theses, Dissertations, Professional Papers, and Capstones

The United States government has been funding infrastructure expansions and upgrades to bring Internet access to schools and households. While this broadband funding has increased access and adoption, it is unclear how improvements in Internet access affect student performance because Internet access has both productivity and distraction effects. The Internet provides students with access to vast amounts of educational content, instructional videos and other valuable resources that increase productivity. It also provides students access to social media, video games and other forms of entertainment that distract students and reduce student performance. While the literature shows that advances in technology (computers) …

This study will be driven by the following research question: How do students who are homeless or displaced, but earned a scholarship, grant, or both navigate the policies, procedures, and systems of Mountain University during their first two years? Using Resiliency Theory and Hope Theory as the theoretical frameworks, this qualitative multiple case study seeks to identify …

Digitods, Statistical Machine Learning Algorithms, And Internet Cognition: Sociocultural Learning Through Familial Modeling And Mediated Exchanges, Sina Foley

UNLV Theses, Dissertations, Professional Papers, and Capstones

With ever-advancing technology and the ubiquity of smart devices, younger generations of children are growing up with access to smart mobile technology from birth. These digitally acculturated children ages 0-5, or digitods, are learning to make sense of the world in large part through sociocultural exchanges in the home. As these digital natives are habituated to mobile media, prevalent and accessible, they are also opened to data-mining and target-marketing as their online engagement signals algorithmic function. This study adds to our understanding of how digitods may be susceptible to algorithmic culture and strategic digital marketing, as familial modeling and mediated …

Relationships Between Healthcare Technology Experience, Acceptance, Attitudes, Self-Efficacy And Readiness In Pre-Licensure Nursing Students, Emily Lynne Boyce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Technology is embedded in many aspects of healthcare. This is especially true in nursing, where technology is used daily in charting, medication administration, clinical decision-making, healthcare team communication, and information resource utilization. In nursing programs, students are exposed to healthcare technologies and expected to use them once entering the workforce. Healthcare technologies such as electronic health records (EHR), barcode medication administration, medication dispensing machines, and mobile technologies are critical to adopt to leverage their efficiencies and safety mechanisms to provide the best patient care. Despite evidence indicating the benefits of using healthcare technologies, new graduate nurses enter the workforce …

“But What About Me?”: How Memorable Messages Received During Catholic Sex Education Contribute To The Development Of Identity Gaps, Hannah Novak

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sex education in the United States is a widely debated issue. Christians have supported abstinence-based education in the United States for decades (Dent & Maloney, 2017). There are numerous studies that have examined how abstinence sex education is faulty, specifically religious sex education (Judge, 2020; Levand & Ross, 2021; Rasmussen, 2010; Reuther, 2008). Studies found that religious sex education led to mental, physical, and emotional health disparities in the United States (Baker et al., 2015; Nelson et al., 2017). This study explored how memorable messages received in Catholic sex education led to the formation of identity gaps in participants' lives. …

Fear Of Recurrence As A Mediator Of Illness Perception And Perceived Stress In Acute Myocardial Infarction Survivors, Sarah E. Zvonar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: The primary objective of this study is to evaluate fear of recurrence as a mediator of illness perception and perceived stress. This research will determine how illness perceptions and fear of recurrence affect perceived stress in the acute myocardial infarction (AMI) population. Other aims will observe how demographics predict patients who may experience increased fear of recurrence and stress in the AMI population, how the variables of fear of recurrence change over time, and if fear of recurrence is still a significant mediator after controlling for depression and anxiety.Rational/ Conceptual Basis/ Background: Acute myocardial infarctions (AMIs) are often accompanied …

Examining The Effects Of Perspective-Taking And Empathetic Concern On Attractiveness Biases In Millennial And Generation X Adults, Stephanie Verba-Quinones

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the effects of perspective-taking and empathetic concern on attractiveness biases and stereotypes in Generation X and Millennial adults. Such biases and stereotypes are pervasive and can lead to preferential treatment and differential outcomes for individuals of varying attractiveness levels (see Langlois et al., 2000 for review). Previous research suggests that social media may amplify the importance placed on attractiveness, particularly for women (Fardouly et al., 2015; Perloff, 2014; Tiggemann et al., 2014; Toma & Hancock, 2018). Given the negative impacts of biases and stereotypes, this study sought to investigate pathways to reduce attractiveness biases and stereotypes …

Development And Initial Validation Of The Mindful Self-Regulated Learning Scale (M-Srls), Sarah Wolff

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modern mindfulness is a catch-all term. Just exactly what it looks like within the context of education and how it is taught vastly varies. As such, program fidelity and integrity is questioned. Here a definition of mindful self-regulated learning is proposed and the Mindful Self-Regulated Learning Scale (m-SRLS) is developed. This includes item generation and development, systematic testing of item performance, scale dimensionality, convergent and divergent validity, measurement invariance across groups and subgroups, and scale reliability over a series of five pilot studies and five primary studies using independent samples. The resulting m-SRLS is a context specific measurement tool that …

The Role Of Style In Community Identity And Group Affiliation: An Archaeological Study Of Virgin And Kayenta Branch Ceramics, Daniel Melvin Perez

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research focuses on the Virgin Branch heartland of the North American Southwest, an archaeological area spanning southern Nevada, southwestern Utah, and northwestern Arizona. The interplay of Virgin Branch community identity, group affiliation, and social interaction over time, between ca. 300 B.C. and A.D. 1225, is considered intra-regionally and in the context of interactions with neighboring Kayenta Branch populations of northeastern Arizona. The principal question for this research is: How is Virgin Branch group identity communicated and reflected through expressions of technological and painted designs styles on pottery amidst intra- and inter-regional events and interactions over time? Support for this …

Developmental Differences In School Climate Predictors Of Chronic School Absenteeism, Michael Fensken

UNLV Theses, Dissertations, Professional Papers, and Capstones

School attendance problems (SAPs) represent a critical developmental challenge for youth. SAPs represent a spectrum from difficulties attending school despite complete school attendance to complete absence. Ongoing SAPs can lead to chronic absenteeism, which may be defined as missing 8.3–10.0% (15–18 days) of school in an academic year. However, debate exists over the utility of a demarcation for chronic absenteeism. A shortcoming of cutoffs to defining problematic chronic absenteeism is that demographic, academic, symptom, and family variables are not delineated clearly. Yet, the present intervention frameworks (e.g., multi-tiered systems of supports models; MTSS) rely on clear delineations of such variables …
