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 …

Temporally Weighted Averaging: The Effects Of Test Delay On Spontaneous Recovery Of Choice, Jack Van Allsburg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Foraging animals in natural environments must track the value of different behavioral options in order to make decisions that maximize their food intake. The process by which they track this value is poorly understood, but holds relevance for our understanding of how animals make choices in general. In a series of experiments conducted in operant chambers, we put rat subjects in a choice scenario where they could press two levers, one of which would intermittently produce the delivery of food pellets on a rich (more frequent) schedule, while the other would do the same on a lean (less frequent) schedule. …

Executive Functioning In Children With Autism And Co-Occurring Neurodevelopmental Disorders: A Systematic Review And Quantitative Analysis, Kandice Benallie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children with autism and other NDDs experience some level of executive dysfunction including challenges with problem-solving, judgement, working memory, and flexibility. Considering autism and other NDDs including ADHD and ID have overlapping symptoms, it can be difficult to differentially diagnose the disorders. This dissertation sought to explore how co-occurring ADHD and ID impact the EF of autistic children. The first study systematically reviewed the current research examining EF of autistic children with co-occurring ADHD and ID. Findings suggest that co-occurring ADHD and ID result in increased executive dysfunction as compared to children with autism only. The systematic review also revealed …

The Mental Health Correlates Of Microaggressions Towards Transgender And Gender Diverse People Of Color: Moderating Effects Of Identity Affirmation And Lgbtq+ Community Connectedness, Kevin Chi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

LGBTQ+ (lesbian, gay, bisexual, transgender, queer, or other meaningful self-labeled sexual and gender identities) individuals experience daily stressors (e.g., discrimination, violence, hypervigilance, negative expectations) that contribute to poorer mental health outcomes (e.g., depression, anxiety, posttraumatic symptoms, substance). For LGBTQ+ people of color (POC), identifying with multiple intersecting marginalized identities creates unique experiences of inequality that expose them to additional stressors, contributing to poorer mental health outcomes. Perceiving microaggressions, daily brief, everyday assaults on marginalized individuals, about one’s identity has been found to have negative mental health effects. TGD (transgender and gender diverse) POC face exposure to multiple types of microaggressions …

Adverse Childhood Experiences, Discrimination, & Adulthood Health Outcomes: Impacts Of Protective And Compensatory Experiences In Childhood, Sallie A. Mack

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adversity encompasses a wide range of stress-inducing experiences that are often prolonged and/or recurring in nature. Adverse childhood experiences (ACEs) capture adversity experienced before the age of 18, including abuse, neglect, and general household dysfunction. ACEs are widely linked to physical and mental health outcomes across the lifespan. Racial/ethnic discrimination, a form of adversity that can occur across the lifespan, has also been linked to many negative health outcomes. Protective and compensatory experiences in childhood (PACEs) are a relatively newer conceptualization of early-life resiliency factors. Early life resiliency is linked to positive health outcomes later in life. Our studies investigated …

The Longitudinal Effects Of Adverse Childhood Experiences On Internalizing And Externalizing Problems: In Search Of Demographic Disparities, Cynthia M. Navarro Flores

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children experience high rates of emotional problems (e.g., anxiety, depression) and behavioral problems (e.g., defiance, aggression) that can have long-lasting detrimental effects. Emotional/behavioral problems have been found to relate to exposure to adversity during childhood (i.e., adverse childhood experiences [ACEs]). Studies have found that rates of exposure to ACEs and emotional/behavioral problems may vary depending on one’s race/ethnicity, sex, and income. Research has not yet looked at how emotional/behavioral problems develop throughout childhood in conjunction to exposure to ACEs. The current two-paper dissertation focused on examining the individual and conjointly developing trajectories of ACEs, and emotional (i.e., internalizing problems) and …

App-Based Academic Interventions For Children With Autism, Cassity R. Haverkamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Technology, such as tablet/phone apps, robots, video games, and virtual reality, can be used to teach skills to autistic children. Research on technology supports for autistic youth often focus on social skills, a main part of an autism diagnosis. However, autistic children may also have academic challenges, and fewer studies have looked at how technology can teach academic skills to children with autism. We created three studies to look at how academic apps may benefit autistic children. In the first study, we reviewed studies that looked at how academic apps can increase the academic skills of children with autism. We …

How Systematically Increasing Estimator Variables Affects The Confidence-Accuracy Relationship, Amber M. Giacona

Graduate Theses and Dissertations

Researchers have used signal-detection theory-based approach to show that when police use proper practices with eyewitnesses, highly confident witnesses will be highly accurate even when viewing conditions may be suboptimal (Wixted & Wells, 2017). This is referred to as the pristine conditions hypothesis. There have been multiple, and often contradictory, studies that have investigated the relationship between viewing conditions and memory degradation (Giacona et al., 2021; Grabman et al., 2019; Lockamyeir et al, 2020; Semmler et al., 2018). In the current study, I systematically manipulated five estimator variables (lighting, distance, retention interval, exposure duration, and race) as either suboptimal or …

Exploring Gastrointestinal Health In Mecp2 Duplication Syndrome, Davut Pehlivan, Muharrem Ak, Daniel G Glaze, Bernhard Suter, Kathleen J Motil

Faculty, Staff and Students Publications

BACKGROUND: MECP2 duplication syndrome (MDS) is a rare neurogenetic syndrome caused by duplications of MECP2 at the Xq28 region. Although constipation and gastrointestinal reflux are reported in MDS, a comprehensive characterization of gastrointestinal health has not been fully explored.

METHODS: We conducted a parent survey to explore the characteristics of gastrointestinal health in individuals with MDS using a secure online registry and compared differences in gastrointestinal symptoms between individuals with MDS and those with Rett syndrome (RTT).

KEY RESULTS: One hundred six surveys were analyzed. Symptoms commonly associated with constipation occurred in 72% to 89% of MDS individuals. Eleven percent …

The Emotional Intelligence And Conflict Management Relationship In Black Women Leaders, Tina Raylyn Jackson

Electronic Theses and Dissertations

This study examined the relationship between emotional intelligence and conflict management styles in Black women leaders in the United States. The lack of literature surrounding Black women leaders' emotional intelligence or conflict management styles presented an opportunity to offer quantitative data connected to these constructs. A cross-sectional survey design was used to administer three surveys the Situational Test of Emotional Management- B, the Kraybill Conflict Style Inventory, and a modified version the Multidimensional Inventory of Black of Identity, that focused on Black female identity. Data from 124 participants were analyzed to learn if identity mediated the relationship between emotional intelligence …

Considering Contextual Factors In The Perception And Attribution Of Racial Microaggressions, Roselee Ledesma

Graduate Theses and Dissertations

Black, Indigenous, People of Color (BIPOC) experience interactions with subtle or ambiguous racial undertones that may be perceived as discriminatory, benign, or even complimentary. These interactions have been labeled microaggressions or a subtle form of everyday discrimination. Microaggressions are associated with detrimental health and cognitive effects (Lui & Quezada, 2019; Ozier et al., 2019). To better understand and label microaggressions, it is important to consider contextual factors. For example, the same statement or behavior is likely interpreted differently depending on who is involved, what is said or done, when it occurs, where it takes place, and why the statement or …

Cultural Competence Among Child Life Professionals, Rachel Burger

Graduate Theses and Dissertations

There is an ever-growing need for individuals to work towards cultural competence, especially when those individuals work in healthcare. As healthcare professionals with backgrounds in child development and who provide emotional and psychological support to diverse pediatric patient populations in a variety of different sectors, child life specialists (CLS) and Certified Child Life Specialists (CCLSs) have an even greater need for understanding cultural competence (Thompson, 2009). The purpose of the current study was to examine the cultural competency levels of CCLSs, the type of cultural competence professional development units (PDUs) they participate in, and their perspectives on cultural competence in …

Examination Of A Measure To Assess Clients’ Perceptions Of The Client-Provider Relationship In Home Visiting Services, Bethelhem Belachew

Dissertations

Home visiting services are prevention-or intervention-based programs provided to caregivers during the prenatal period through the first few years of a child’s development (Shonkoff & Phillips, 2000). Engagement in services is documented to improve caregivers’ knowledge of child development and parenting practices (e.g., home safety, nutrition; Ammerman et al., 2006). Despite these benefits, programs are challenged with high levels of attrition (Gomby, Culross, & Behrman, 1999). One reliable predictor of client engagement in services is the client-provider relationship. However, measures that have been developed to assess the clients’ perception of their relationship with their home visitor relationship are limited (Girvin …

Exploring The Dimensions Of Lesbian, Gay, And Bisexual Affirmative Clinical Supervision, Lindsey N. Dollar

Dissertations

Graduate programs have continued to improve over time regarding incorporating training on LGB issues into coursework and practicum experiences with less emphasis on supervision. Since supervision is a major training area where therapists learn about clients and themselves, it becomes an important area for also teaching supervisees how to work with minority populations. However, relatively absent from discussions of cultural influences in supervision is a focus on LGB concerns, and missing is the ‘how to’ within the supervisory relationship. This quantitative investigation sought to learn how clinical supervisors with knowledge of LGB issues and people implement LGB-affirmative supervision, and to …

Risk And Resilience Factors For Black Individuals Who Face Racial Discrimination, Tabitha M. Mpamira

Dissertations

African Americans report extensive experiences of discrimination across a range of individual, institutional, cultural situations, and more than any other marginalized group (RWJF, 2017). The pervasiveness of discrimination keeps Black individuals at risk of severe physiological ills and heightened risk of psychopathology, including onset of depression and racial trauma symptoms (Williams & Mohammed, 2009). This study investigated risk and resilience factors for Black individuals who face racial discrimination in the United States of America by examining whether encounters of discrimination correlated with psychological distress (depression, anxiety) and racial trauma symptoms. Additionally, the study investigated factors (social support, psychological flexibility, and …

Promoting Equal Interactions In Early Childhood Settings, Daphne Snyder

Dissertations

In the United States, Black, Indigenous, and People of Color (BIPOC) students are more likely to face disciplinary action (e.g., exclusion, suspension, and expulsion from the classroom) for engaging in the same challenging behaviors as their white peers (Badger et al., 2018; Little & Tolbert, 2018; Noguera, 2003). Due to the discrepancy in disciplinary practices, students are at risk of continued negative interactions with their teachers (Decker et al., 2007; Wymer et al., 2020). One way to improve teacher interactions toward BIPOC students is through equity-focused performance feedback regarding praise and reprimand rates (Knochel et al., 2022). The purpose of …

The Effect Of Sleep Deprivation On The Ability To Reappraise Negative Situations, Rebecca Campbell

Graduate Theses and Dissertations

Sleep and emotion regulation are important components of mental health and may function interdependently in the development and maintenance of mental health disorders. Unfortunately, there is limited experimental work on the impacts of sleep deprivation on reappraisal, a common emotion regulation strategy, in adults. Furthermore, increases in negative and decreases in positive affect are often associated with sleep loss. This study aimed to examine the relation between sleep deprivation and emotion regulation by asking adults to reappraise a series of vignettes before and after a randomly assigned night of sleep deprivation or normal sleep. Additionally, measures of self-reported emotion regulation …

Juvenile Justice System Involvement And The Transition To Early Adulthood: Does Direct Intervention Help Or Harm?, Cameron Miller Perrine

Graduate Theses and Dissertations

The present study examines the effects of the juvenile justice system on youth as they transition to early adulthood. The present study adds to the literature by incorporating comparison groups of youths and by testing multiple explanations of recidivism: Labeling Theory and the Life Course perspective. In total, 267 adults were recruited via online survey and sorted into three groups: Externalizing Behavior and Juvenile Justice Involved, Externalizing Behavior and Not Juvenile Justice Involved, and Not Externalizing and Not Juvenile Justice Involved. In addition to demographics, participants completed measures of past externalizing behaviors, past juvenile justice involvement, social disadvantage, deviant peer …

Components Of Emotional Functioning Among People With Substance Use And Posttraumatic Stress Difficulties: An Idiographic Perspective, Danielle Higuera

Graduate Theses and Dissertations

Prior research has examined components of emotional functioning (e.g., clarity, physiological sensations, expression, regulation) among people with substance use and/or posttraumatic stress at the group level; however, a more cohesive/comprehensive understanding of how these factors unfold and connect for individual people who comprise these populations is needed. The current study used a qualitative interview design to explore the emotional worlds of participants (N = 44) who comprised four groups (substance use [n ¬= 11], posttraumatic stress [n = 12], co-occurring substance use and posttraumatic stress [n = 11], and healthy controls [n = 10]) to gain a person-level understanding of …

Presentation Matters: Effects Of Presentation Order Of Personality Feedback And Need For Structure On Participant Response To Feedback, Alita Marie Mobley Tu

Graduate Theses and Dissertations

Psychological assessment plays a vital role in differential diagnosis, treatment planning, and measurement of treatment effectiveness. Insufficient or ineffective feedback to the client can limit the utility of psychological assessment. Finn and Tonsager (1997) advise that assessment feedback will be best received when the feedback content is ordered to start with information that is most consistent with the client’s existing self-concept to information that is the most discrepant from their self-concept. There is minimal empirical support for this practice recommendation. The current study investigates the relationship between presentation order of personality feedback and participant response to feedback (i.e., feedback evaluations, …

Her Story Told Her Way: A Narrative Inquiry Into Black Women’S Perception Of The Strong Black Woman., Chulyndria Chanee Laye

Graduate Theses and Dissertations

The narrative surrounding the meaning of being a Black woman has historically been dominated by stereotypes such as the mammy, jezebel, sapphire, and angry Black woman. Black women have attempted to control their own narrative through the internalization of these stereotypes, leading to the creation of the Strong Black Woman (SBW) construct. While the SBW is comprised of a sense of caretaker, independence, and emotional restraint, Black women’s attempts at embodying this construct in the face of societal oppression and familial responsibilities can and often does have negative effects on their mental health. Although the behaviors associated with the SBW …

Exploring Body Image Related Cognitive Fusion As A Maintenance Mechanism Of Eating Disorder Pathology, Jennifer L. Barney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eating disorders are serious mental health conditions that can have serious negative effects on a person’s physical and mental well-being. These disorders are typically complex, and individuals are often struggling with one or more comorbid mental health problems, making them difficult to treat. To address this complexity and hopefully improve treatment outcomes for those with eating disorders, psychology research examining individual differences that appear to be related to differential treatment responses is needed. Better understanding how these factors relate to each other can help treatment providers identify the treatment methods most likely to work best for a specific individual based …

Telehealth Acceptance And Commitment Therapy For Adolescents With Transdiagnostic Health-Related Anxiety: A Randomized Controlled Trial, Julie M. Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Health-related anxiety is a growing issue to understand how to treat, particularly following the COVID-19 pandemic. Some studies show that a specific type of therapy, acceptance and commitment therapy (ACT), may be beneficial for health anxiety in adults, but this has not yet been tested with adolescents. The present study is a randomized, waitlist-controlled trial of ACT delivered via Zoom for adolescents struggling with health-related anxiety. A total of 30 adolescents (ages 12-17), plus one caretaker each (N = 60), living in Utah and currently struggling with health-related anxiety were enrolled. The majority of caretakers and adolescents were White, non- …

Act And Veterans: A Multiple Baseline Study Using Act To Treat Anxiety Disorders In U.S. Military Veterans, Jeremiah E. Fruge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are 18 million Americans, roughly 7% of the population, who are Veterans. In contrast with the general population, Veterans have a high likelihood of exposure to psychological harm during their military service. For example, studies indicate Veterans are diagnosed with anxiety disorders in some cases four times higher than in the general population, though few studies examine treatment. Military culture is an additional factor which is important to account for when treating Veterans. For example, within the military an emphasis is placed on values and committed action which may mean this population will benefit more from certain therapies than …

Examining The Association Between Emotional Intelligence, Meaning In Life, Stress, And Burnout Among Preâ??Medical Students In The United States, Nayla Paulina Paulina Bejarano Chacon

Open Access Theses & Dissertations

Background and significance: The Association of American Medical Colleges (AAMC) has estimated that by 2034 there will be a physician shortage of around 124,000 physicians. With burnout being one of the main drivers, it is crucial to assess it. Burnout is characterized by high levels of emotional exhaustion and cynicism and low levels of academic efficacy.There has been substantial research on burnout among healthcare providers across different levels of training; however, few studies have examined burnout among undergraduate students who wish to pursue a graduate degree in healthcare. Given the shortage of healthcare providers in the United States, it is …

The Power Of A Story: How Emotions And Numeracy Affect Parental Decisions About The Human Papillomavirus Vaccine, Candice Fawn Coffman

Open Access Theses & Dissertations

The Human Papillomavirus (HPV) is the most common sexually transmitted infection (CDC, 2021). There are two strains of HPV known for causing cervical, penile, anal, vaginal, and oropharynx (throat) cancers (CDC, 2020). A vaccine is available to prevent these cancer-causing strains of HPV for individuals between the ages of 9-45. Unfortunately, vaccination uptake and completion rates are below the recommended rates to achieve herd immunity. A primary barrier to vaccination is concern about potential adverse events following vaccination. The purpose of the present study is to examine the influence of anecdotal versus statistical information on parents' intentions to vaccinate their …

The Mediation Effects Of Adaptive Blindness Strategies On The Relation Between Institutional Betrayal From Military Sexual Assault And Mental Health Symptoms, Rachel L. Davies

Psychology Theses & Dissertations

Military sexual assault is a serious and prevalent issue. The frequency with which military sexual assault occurs and the nature of the response to these events within the military system may contribute to institutional betrayal. Institutional betrayal is the failure of an institution, such as the military, to prevent sexual assault from occurring and/or the failure to support a survivor after sexual assault. Adaptive blindness strategies are forms of coping strategies that help individuals navigate a relationship they depend on when there is a betrayal. Two adaptive blindness strategies are self-blame and minimization. Although the adaptive blindness strategies may allow …

Attention And Task Engagement During Automated Driving, James Richard Unverricht

Psychology Theses & Dissertations

Many young drivers suffer fatal crashes each year in the United States at a rate approximately three times greater than more experienced drivers. Automated driving systems may serve to mitigate young drivers high crash rates but remain underexplored in research. This dissertation project examined the effects of levels of automation and interestingness of auditory clips on latent hazard anticipation in young drivers during simulated driving. Participants drove a vehicle at varying levels of vehicle automation (SAE Level 0, 2, or 3) in simulated scenarios, each containing a latent hazard event during which a boring, neutral, or interesting auditory clip was …

The Influence Of Minority Stress, Coping, And A Pandemic On The Relationship Between Sexual Orientation And Mental Health: A Mixed Methods Study, James Michael Macchia

Psychology Theses & Dissertations

For decades, scientific literature has shown that sexual minority individuals across populations are disproportionately affected by negative mental health outcomes when compared to their heterosexual counterparts. These disparities are largely attributable to minority stress. Coping is a significant factor that can impact the content and severity of mental health outcomes and coping behaviors have been shown to vary based on sexual orientation. Mental health outcomes may also differ between sexual minority subgroups due to additional factors such as double discrimination and bisexual invisibility/erasure. Moreover, factors such as internalized homophobia and community connectedness have demonstrated strong associations with sexual minority mental …

Affect, Mind-Body Factors, And Disordered And Intuitive Eating Behaviors: Examining Naturalistic Associations Among Young Women With Elevated Eating Disorder Symptoms, Kelly A. Romano

Psychology Theses & Dissertations

Objective: The present study examined whether three mind-body factors—emotion dysregulation, interoceptive sensibility, and mindfulness—that are theorized to be implicated in the onset and maintenance of eating disorder (ED) pathology mediated (Aim 1) and moderated (Aim 2) within-person associations between affect and women with elevated ED symptoms’ disordered and intuitive eating behavior use. Method: Participants included 150 young women with elevated ED symptoms who completed a 10-day ecological momentary assessment protocol. To address Aim 1, multilevel structural equation models examined whether the mindbody factors (separately) mediated momentary associations between negative and positive affect, and women’s disordered (dietary restriction, loss of control …
