Discovering Motor Phenotypes In Autism Spectrum Disorder: A Cross-Syndrome Approach, Daniel Edwin Lidstone

UNLV Theses, Dissertations, Professional Papers, and Capstones

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with a behavioral phenotype characterized by persistent deficits in social communication and social interaction accompanied by restricted, repetitive patterns of behaviors, interests, or activities. Currently in the US, approximately 2.5% of children have a diagnosis of ASD. The etiology of ASD is complex, however the disorder does have a strong genetic basis. Specific genetic mutations can lead to neuroanatomical and neurophysiological changes during development resulting in a behavioral phenotype that falls along the ASD spectrum and may result in a diagnosis of ASD. The severity of ASD-specific behaviors falls on a continuum …

Empirical Justification For Supportive Other Involvement In Collegiate Athletes’ Mental Health Intervention, Elena Gavrilova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student-athletes have been identified to evidence similar or higher rates of mental health difficulties and lower levels of mental health engagement as compared with non-athlete peers. Along these lines, sport-specific mental health intervention has been justified by researchers, yet only one randomized clinical trial has been conducted in collegiate student-athletes who have been formally assessed for mental health disorders (i.e., a family behavior therapy as compared with traditional campus counseling as usual; Donohue et al., 2018a). Results of this outcome study demonstrated greater improvements for participants who received the family-based intervention up to 8-months post-randomization. In this clinical trial, the …

Consequences Of Math Anxiety And Stereotype Threat: An Intersectional Perspective, Jennifer E. John Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with science, technology, engineering, and math (STEM) skills are highly valued for their contribution to the U.S. workforce and society. However, women and some people of color enter STEM fields at lesser rates than do White men. Math anxiety and stereotype threat have been found to cause math performance decrements for women and some people of color. Presently, it is not clear how math anxiety and stereotype threat might work together to dually influence math performance and subsequent STEM participation. The current study focuses on a diverse sample of 295 undergraduate students who were randomly assigned to one of …

Visual Attention And Emotion Regulation In Schizophrenia, Bern Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotion regulation and emotion processing deficits cut across the varying symptom presentations of schizophrenia. Emotion processing deficits are inadequately treated by pharmacologic interventions and are related to real-world functional impact and disability. This study investigated behavioral and psychophysiological responses to a series of emotion regulation tasks while concurrently collecting eye tracking data as an index of visual attention. A brief neurocognitive assessment was also completed in order to examine potential cognitive determinants of emotion. Participants completed tasks designed to assess cognitive change and directed attention strategies for down-regulation of unpleasant and pleasant emotion. For each of our two unpleasant emotion …

Improving Community College Students' Interest, Utility-Value, And Performance: How Does Future Time Persective Influence A Utility-Value Intervention?, Elsa Maria Mason

UNLV Theses, Dissertations, Professional Papers, and Capstones

The economic benefits of academic success and completion are long-lasting. Students who attend community colleges can stand to benefit a great deal by completing a 4-year degree or even a 2-year degree. Unfortunately, these students often begin their higher education journey not fully prepared for college-level coursework. Students often fail to see how their college coursework relates to their lives and in turn, don’t hold interest or perceive value for the course and consequently do not perform well. Using Eccles et al. (1983) expectancy-value theory this study tested how community college students would respond to a utility-value intervention in which …

Forgetting Distractors: Inhibition Or Decay?, Laura Werner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on forgetting irrelevant information in working memory (WM) has supported two

conflicting theories, inhibition (Oberauer & Lewndowsky, 2016) and decay (Dagry et al., 2017;

Dagry & Barrouillet, 2017). However, these conflicting results may be due to the fact that different methods were used to assess each model. In Experiment 1, we combined those methods to create a modified distractor span task that allows for a direct comparison of the models. Participants processed words that were to be remembered (targets) and others that were to be forgotten (distractors); the amount of free time after each distractor varied, with total trial …

Reconciling Contemporary Approaches To School Attendance And School Absenteeism: Toward Promotion And Nimble Response, Global Policy Review And Implementation, And Future Adaptability (Part 2), Christopher Kearney, Carolina Gonzálvez, Patricia A. Graczyk, Mirae Fornander

Psychology Faculty Research

As noted in Part 1 of this two-part review, school attendance is an important foundational competency for children and adolescents, and school absenteeism has been linked to myriad short- and long-term negative consequences, even into adulthood. Categorical and dimensional approaches for this population have been developed. This article (Part 2 of a two-part review) discusses compatibilities of categorical and dimensional approaches for school attendance and school absenteeism and how these approaches can inform one another. The article also poses a multidimensional multi-tiered system of supports pyramid model as a mechanism for reconciling these approaches, promoting school attendance (and/or prevention of …

Utilizing The Community-Based Research Approach To Examine Mental Health And Support Services Issues Related To Hiv-Associated Neurocognitive Disorder, Renato M. Liboro

Psychology Faculty Research

Human immunodeficiency virus (HIV)-associated neurocognitive disorder is an emergent public health problem known to HIV researchers and scientists, but unfortunately, is a concern that still needs to be better recognized by people living with HIV and HIV service providers. Research studies have reported that between 30 to 50% of people living with HIV who have access to combination antiretroviral therapy are and will be affected by this disorder. This raises the need to find more appropriate research approaches for examining issues that will significantly impact people living with HIV experiencing or at risk of developing neurocognitive impairments. People living with …

Impaired H-Reflex Adaptations Following Slope Walking In Individuals With Post-Stroke Hemiparesis, Jing Nong Liang, Yun Ju Lee, Eric Akoopie, Brooke Conway Kleven, Trisha Koch, Kai-Yu Ho

Physical Therapy Faculty Publications

Background and Purpose: Short term adaptations in the Ia afferent-motoneuron pathway, as measured using the H-reflex, in response to altered ground reaction forces (GRFs) applied at the feet during slope walking have been observed in the non-impaired nervous system. The ability of the stroke-impaired nervous system to adapt to altered GRFs have not been examined. The purpose of this study was to examine the acute effects of altered propulsive and braking forces applied at the feet, which naturally occurs when walking on different slopes, on adaptations of the H-reflex pathway in individuals with chronic post-stroke hemiparesis.

Multi-Polygenic Risk Score Prediction Model For Bipolar Disorder, Travis Mize

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder (BP), a severe mental disorder characterized by recurring manic and depressive episodes, has been shown to have a strong genetic underpinning. Current theory suggests that it is the summation of risk alleles, spread across the entirety of the genome, which contributes to the development of BP, as well as other polygenic traits. The comorbid nature of these polygenic traits are often problematic for diagnosticians as the symptomology of the disorders may vary substantially between individuals and can create diagnostic confusion. To alleviate issues such as these, a more objective measure, to be used alongside current diagnostic procedures, is …

Multimethod Investigation Of Pristine Inner Experience, Leiszle Rae Lapping-Carr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introspection can be defined as any effort to observe and report on internal experiences. As such, introspection continues to be a commonly used research method, including self-report questionnaires, experience sampling, and qualitative interviews. However, in these modern applications of introspection, the challenges of such endeavors are often not readily acknowledged or addressed. This study compared three introspective methods using a pre-test, post-test design: descriptive experience sampling (DES), the experience sampling method (ESM), and daily questionnaires (DR). Those who participated in DES, a beeper-based method designed to produce high fidelity understandings of random moments of inner experience, had lower average frequencies …

Animal Assisted Therapy And Support Animals, What Mental Health Professionals Know And Understand, Alexandro H. Velez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Animal-assisted therapy can greatly benefit mental health professionals with clients in and out of the school settings in many ways. It is believed mental health professionals are successfully implementing Animal Assisted Therapy, even though some are not. Mental health professionals who are not using Animal Assisted Therapy are not doing so as the result of various variables, such as lack of information, knowledge, training, certification and policies, which prevents them from using Animals Assisted Therapy with clients and the community. It is also believed some mental health professionals are using animals as part of therapeutic interventions without proper training. The …

A Controlled Examination Of Motivational Strategies: Reviewing Positive Consequences For Goal Achievement, Negative Consequences For Undesired Behavior, And A Relaxation Exercise, Yulia Gavrilova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Motivation is an integral part of human life and one of the most fundamental aspects of behavior change. Of interest to the present study are two motivational approaches, Negative Consequences Review (NCR) and Positive Consequences Review (PCR). NCR is an intervention component originally designed as part of Family Behavior Therapy (FBT) to motivate individuals with their goals through a discussion of negative consequences associated with undesired behaviors. PCR was developed as an auxiliary component of FBT to inspire individuals’ motivation to achieve their goals through a discussion about positive consequences of reaching goals. Purpose: The purpose of this study …

The Effects Of Problems Attributed To Culture On The Mental Health Of Athletes, Corey Rae Kuhn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Demographic changes in the United States during the past century and recognition of the importance of diversity have increased interest in research involving ethno-cultural factors that impact mental health. For example, important psychological constructs, such as self-concept and ethnic identity, have been indicated to develop within cultural context and impact psychological wellbeing (Brittian et al., 2013). The field of psychology, as a whole, is evaluating the merits of etic and emic approaches to research and clinical practice while exploring the importance and application of multicultural counseling/therapy (MCT; Sue & Sue, 2013). In contrast, within sport psychology, the influence of ethnic …

Validating Empathy As Captured By The Meanness In Psychopathy-Self Report, Stephanie Marie Molina

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychopathy is a distinctive personality disorder with an array of interpersonal and affective deficits. In particular, deficits in affective and cognitive empathy skills are noted to be a central feature of psychopathy. Specifically, the construct of psychopathic meanness, which is conceptualized as a tendency to act aggressively without regard for others, is preferentially related to deficient empathy. To elucidate the relationship between psychopathic meanness and empathy, three studies were conducted utilizing the Meanness in Psychopathy-Self Report (MiP- SR). The MiP-SR is a new measure that parses apart the construct of psychopathic meanness into three factors: Malice, Coldness, and Imperviousness. MiP-SR …

Implementing Autism Screening For Latino Children In Primary Care: Perspectives From Parents And Providers, Mary Troxel, Keri Linas, Diane Jacobstein, Matthew Biel, Sandra H. Soto, Isabella Lorenzo-Hubert, Soraya Dos-Santos, Rocio Mendez, Bruno J. Anthony

Journal of Health Disparities Research and Practice

While Autism Spectrum Disorder (ASD) and other developmental disabilities are being diagnosed at increasing rates, there is strong evidence of disparities in rates of identification and utilization of services by Latino children as compared to non-Latino children. Attempts to reduce these disparities include culturally-informed early screening for ASD risk. In preparation for initiation of a screening program in a primary care setting serving primarily Latino children, focus groups and interviews were conducted with Latino parents (N=31), medical staff (N=15), health care providers (N=4) to better understand the barriers and facilitators to engagement around developmental concerns that contribute to the low …

Predictors And Missed Opportunities For Blood Glucose Screening Among African Americans: Implications For Church-Based Populations, Alexandria G. Bauer, Jannette Berkley-Patton, Carole Bowe Thompson, Kelsey Christensen

Journal of Health Disparities Research and Practice

African Americans (AAs) are disproportionately diagnosed with prediabetes, diabetes, and related complications. Guidelines for prediabetes/diabetes screening emphasize reaching at-risk adults. The AA church has potential to increase reach of BGS with AA church members and community members. The current study identified predictors of blood glucose screening (BGS) and individuals with missed opportunities for BGS among church-affiliated AA adults. Participants were drawn from a previous pilot study (Project Faith Influencing Transformation) conducted in six AA churches over eight months. Eligibility criteria included self-identifying as AA and being aged 18 or older. Participants who had previously been diagnosed with diabetes were excluded, …

Identification Of A Core Amino Acid Motif Within The Α Subunit Of Gabaars That Promotes Inhibitory Synaptogenesis And Resilience To Seizures, Anna J. Nathanson, Yihui Zhang, Joshua L. Smalley, Thomas A. Ollerhead, Miguel A. Rodriguez Santos, Peter M. Andrews, Heike J. Wobst, Yvonne E. Moore, Nicholas J. Brandon, Rochelle M. Hines, Paul A. Davies, Stephen J. Moss

Psychology Faculty Research

The fidelity of inhibitory neurotransmission is dependent on the accumulation of γ-aminobutyric acid type A receptors (GABAARs) at the appropriate synaptic sites. Synaptic GABAARs are constructed from α(1-3), β(1-3), and γ2 subunits, and neurons can target these subtypes to specific synapses. Here, we identify a 15-amino acid inhibitory synapse targeting motif (ISTM) within the α2 subunit that promotes the association between GABAARs and the inhibitory scaffold proteins collybistin and gephyrin. Using mice in which the ISTM has been introduced into the α1 subunit (Gabra1-2 mice), we show that the ISTM is critical for axo-axonic synapse formation, the efficacy of GABAergic …

Allocation To Groups: Examples Of Lord's Paradox, Daniel B. Wright

Educational Psychology, Leadership, and Higher Education Faculty Research

Background Educational and developmental psychologists often examine how groups change over time. Two analytic procedures – analysis of covariance (ANCOVA) and the gain score model – each seem well suited for the simplest situation, with just two groups and two time points. They can produce different results, what is known as Lord's paradox. Aims Several factors should influence a researcher's analytic choice. This includes whether the score from the initial time influences how people are assigned to groups. Examples are shown, which will help to explain this to researchers and students, and are of educational relevance. It is shown that …

The Neurocognitive Process Of Digital Radicalization: A Theoretical Model And Analytical Framework, Tiffiany Howard, Brach Poston, Stephen D. Benning

Political Science Faculty Research

Recent studies suggest that empathy induced by narrative messages can effectively facilitate persuasion and reduce psychological reactance. Although limited, emerging research on the etiology of radical political behavior has begun to explore the role of narratives in shaping an individual’s beliefs, attitudes, and intentions that culminate in radicalization. The existing studies focus exclusively on the influence of narrative persuasion on an individual, but they overlook the necessity of empathy and that in the absence of empathy, persuasion is not salient. We argue that terrorist organizations are strategic in cultivating empathetic-persuasive messages using audiovisual materials, and disseminating their message within the …

International Conference on Gambling & Risk Taking

This study reports the prevalence of problematic gambling in Santiago de Chile for the period 2015-2018. Two household-based surveys were implemented in the metropolitan area of Santiago de Chile in 2015 and 2018 in order to assess changes on the prevalence, characteristics and severity of gambling (n=1030 each; SE=2,2% for a CI=95%). Severity of gambling was measured using the NODS scale.

Results show that during the analysed period the percentage of at-risk players has increased, passing from 14,3% to 16,1%, among them, we identified a decrease in the prevalence of pathological gamblers, passing from 2,4% to 1,4%. We also identify …

What Symptoms Of Disordered Gambling, Disordered Eating, Anxiety, And Depression Co-Occur? The Explanatory Power Of Network Analysis, Nassim Tabri, Melissa Salmon, Samantha Hollingshead, Michael Wohl

International Conference on Gambling & Risk Taking

An abstract (not to exceed 200 words)

Disordered gamblers often exhibit comorbid psychiatric disorders, however, little is known about how or why these disorders co-occur. We posit that comorbidity is likely the result of one or more symptoms of disordered gambling being strongly associated with one or more symptoms of other disorders. To test this idea, we conducted a network analysis to identify relations between individual symptoms of disordered gambling, disordered eating, anxiety, and depression in a representative sample of Canadians from the Bay of Quinte region of Ontario (N=4121). Results indicated that chasing one’s losses was a central symptom …

Gambling-Related Harm And The Prevention Paradox, Matthew Browne

International Conference on Gambling & Risk Taking

Abstract (163 words)

The prevention paradox (PP) describes a situation in which a greater number of adverse events arise from lower-risk population categories, because they are more prevalent than higher-risk groups. There has been limited and conflicting evidence as to whether the PP applies to gambling-related harm.

We assessed the prevalence of 72 harmful consequences from gambling across four risk problem gambling risk categories. Respondents who had gambled on non-lottery forms in the past 6 months completed an online survey (N = 1,524, 49.4% male). The data were weighted to the known prevalence of these risk categories.

The prevalence of …

The Risk For Developing Disordered Gambling: Equal For Every Player? Implications For Research, Policy And Consumer Protection, Gerhard Buehringer

International Conference on Gambling & Risk Taking

Aims: (1) To introduce the concept of individual vulnerability for developing a gambling disorder (GD), (2) to question gambling supply reduction and access limitations as effective GD prevention strategies and (3) to derive short- and long-term implications for research, gambling regulation and consumer protection of vulnerable gamblers. Background: Gambling regulation is currently based on the assumption that participants have similar risks for the development of GD based on individual, social and predominantly gambling-related risk factors. Consequently, GD prevention mainly relies on supply and access limitations and “rational” consumer information and warnings within the Responsible Gambling concept. However, it remains …

Forming partnerships with community leaders the City of Philadelphia learned how former and new gambling activities has impacted the special population group involving the immigrant and refugee community. The discussion will consist of gambling related activities commonly practiced in their culture and the challenges faced when attempting to access services for problem gambling.

Rewarding Responsible Gambling May Increase Tool Use And Attitudinal Loyalty: A Survey Of Members Who Do And Do Not Currently Use Responsible Gambling Tools, Samantha Hollingshead, Michael Wohl

International Conference on Gambling & Risk Taking

Abstract: Loyalty programs are a ubiquitous marketing strategy in the casino industry. Via members’ player accounts, many programs offer access to a money and/or time limit setting tool. Unfortunately, the rate of engagement with limit tools is exceedingly low, which is discouraging from a responsible gambling (RG) perspective. A possible route to increase limit tool use is to reward players for using them with program points. Doing so may also place the casino in a positive light, thus increasing attitudinal loyalty. To test this idea, loyalty program members who use RG tools (N=90) and who have never used RG tools …

Binge Eating And Gambling Are Prospectively Associated With Common And Distinct Deficits In Emotion Regulation Among Community Women, Sarah M. Farstad, Kristin M. Von Ranson

International Conference on Gambling & Risk Taking

This study compared facets of emotion regulation associated prospectively with binge eating and problem gambling to elucidate similarities and differences between eating pathology and a behavioral addiction. Women from the community (N = 202) who engaged in at-risk binge eating (n = 79), at-risk gambling (n = 36), or both behaviors (n = 87) completed four online assessments over six months. Baseline and six-month surveys assessed self-reported emotion dysregulation (including negative urgency and positive urgency), binge eating, and gambling; the abbreviated two- and four-month surveys assessed binge eating and gambling only. Binge eating and problem gambling were …

Professional Competencies For Providing Interventions For Gambling Related Problems And Other High-Risk Behavior – Perspective Of Social Welfare Professionals, Neven Ricijas Ph.D., Sabina Mandic Ma, Dora Dodig Hundric Ph.D.

International Conference on Gambling & Risk Taking

Important aspect of the social welfare system is providing interventions for children and youth with behavioral problems, mainly externalizing behavioral disorders, delinquent behavior and addictions. In Croatia, children and youth can be referred to the social welfare system based on the Social Welfare Act, Family Act or Youth Courts Act, depending on the age, etiology and context of behavioral problems.

The main aim of this study was to explore how often social welfare professionals encounter different phenomenological types of behavioral problems and how confident they feel for providing interventions. Special emphasis will be put on gambling related problems among children …
