Examination Of Factors Reported By Athletes To Interfere With Their Lives Outside Of Sports, Jesse Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The original Sport Interference Checklist (SIC) is a mental-health screening instrument designed to assess the extent to which mental health factors interfere with athletes’ performance during sport training or competition. In addition, the SIC appraises whether athletes are interested in pursuing psychological treatment for the aforementioned factors. Although validated, the SIC does not assess how the aforementioned factors affect athletes’ performance outside of sports. Doing so would permit professionals to examine the influence of these factors across sport training, sport competition, and life outside of sports.

The purpose of this study was to determine the psychometric properties and clinical utility …

Examination Of The Influence Of Consumer Preferences For Cognitive Behavioral Treatment Components And Consumer Effort During Treatment Sessions On Child Welfare Outcomes, Christopher Philip Plant

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: The current study is a secondary analysis of one arm of a controlled trial evaluating the efficacy of FBT-CW for mothers identified for concurrent child neglect and substance abuse (see Donohue et al., 2014). FBT-CW is comprised of multiple cognitive behavioral intervention components targeting skill sets that are hypothesized to influence child neglect and/or substance abuse. The primary areas of focus for these interventions include: (a) management of antecedents to substance abuse and/or child neglect, (b) parenting skills training, (c) communication skills training, and (d) job getting and financial management skills. Purpose: The purpose of this study was to …

Menstrual Cycle Changes In Dysregulated Eating Symptoms, Kimberly S. Stevens

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Animal and human data indicate that fluctuations in ovarian hormones (e.g., estrogen and progesterone) across the estrus/menstrual cycle drive changes in eating behavior. Post-ovulatory phases (i.e., mid-luteal and pre-menstrual in women) correspond to distinct ovarian hormone profiles (i.e., low estradiol or high estradiol coupled with high progesterone) that are known to have stimulatory effects on eating behavior and have been associated with increased risk for emotional eating and binge eating. Nonetheless, other specific components of dysregulated eating (e.g., preoccupation with food, loss of control over eating) that are related to and/or prospectively predict the development of clinical binge eating …

Resilience And The Mental Health Of Bullying Victims: The Role Of Peer Relationships On The Relation Between Bullying Victimization And Social Anxiety, Michelle Catherine Zochowski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bullying is a pervasive issue in today’s schools that has a significant impact on the mental health of students. Resilience has a positive impact on the outcomes related to facing adversity including bullying. The following dissertation study asks whether the relation between bullying victimization and social anxiety differs as a function of resilience and gender. It was hypothesized that bullying victims with increased resilience would show lower levels of social anxiety, as would students that report their gender as female. Chapter one discusses the significance of the problem, defines relevant constructs, and introduces the problem statement. Chapter two outlines the …

Examining The Factor Structures Of The A-Des And Ptci To Identify Unique Predictors Of Ptsd Symptom Clusters In Maltreated Youth, Amanda Howard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on childhood posttraumatic stress disorder (PTSD) has increased over the past decade. Youth who experience maltreatment are more likely to exhibit symptoms of PTSD. At present, the literature largely focuses on youth who have experienced general trauma or PTSD symptoms, while maltreated youth are understudied. To date, no studies have examined the psychometric properties of the Adolescent Dissociative Experiences Scale (A-DES) or the Posttraumatic Cognitions Inventory (PTCI) in a sample of maltreated youth. Predictors of childhood PTSD for maltreated youth remain unknown. The present study was the first research study to date to examine the factor structures of the …

The Relation Between Positive Stereotypes, Negative Stereotypes, And Discriminatory Behavior Toward Hispanic And White Populations, Aileen Ynez Lovitt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research examining positive stereotypes has suggested a possible connection between positive stereotype endorsement and prejudice. This literature, however, has not investigated the relation between positive and negative stereotypes endorsement. Additionally, the combined impact of positive and negative stereotype endorsement predicting prejudice or discrimination has not been considered. Two studies were conducted to address the limitations in past research and gain a better understanding of positive stereotypes relating to behaviors toward out-group racial groups using Hispanic and White participants. Positive stereotypes endorsement was hypothesized to be positively associated with negative stereotype endorsement and was expected to increase the predicted power of …

Dark Tetrad Responses To Moral Dilemmas, Kayli Wrenn

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Dark Tetrad consists of four socially malevolent personality traits: psychopathy, sadism, narcissism, and Machiavellianism. The current study assessed the relationships among each dimension of the Dark Tetrad and moral decision making using sacrificial moral dilemma vignettes. Participants (n = 212 undergraduates) completed two measures of each of the four Dark Tetrad constructs then read a series of 16 sacrificial moral dilemma vignettes. These dilemmas manipulated whether the participant would personally perform the sacrifice and described either the disgusting or sad emotional consequences of the sacrifice. After each vignette, participants rated the moral rightness/wrongness, moral permissibility, and behavioral intention to …

Coping On The Fly: School Psychologists' Perceptions Of Cultural Competence, Jennifer Wynn

UNLV Theses, Dissertations, Professional Papers, and Capstones

The goal of this qualitative ethnographic study is to explore how school psychologists demonstrate multicultural competence (MC) when testing students for K-12 special education. As the population of the United States (US) becomes increasingly diverse, mental health professionals are encouraged to become culturally competent. Cultural competence is the ability to work with culturally and linguistically diverse populations; and being aware of stereotypes, biases and microaggressions. Cultural competence is taught within some psychology preparation programs; however, courses are often limited. Although cross-cultural competencies have been explored in clinical and counseling psychology, they have yet to be explored in the field of …

Depressive Symptoms As A Moderator Of Diurnal Trends In Reward Seeking, Erick Albert William Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anhedonia, a cardinal symptom of a major depressive episode, is the decreased motivation to seek rewards. Individuals with depressive symptoms tend to report reduced positive affect, a distal measure of reward motivation, and engage in less reward-motivated behavior (i.e., reward seeking). However, diurnal rhythms may also influence reward-seeking. Both self-reported positive affect and behavioral measures of reward-seeking increase from the morning to the afternoon and then decreased in the evening. Therefore, the aim of this study was to examine whether reward-seeking varied across time of day and whether anhedonia moderated variation. Overall, reward-seeking did not vary across time of day. …

Tales Of Thriving: Identifying The Underpinnings Of Women's Success In Stem Careers, Sarah E. Thoman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Women remain underrepresented in U.S. science, technology, engineering, and math (STEM) fields. Prior research enumerates many challenges that women experience in STEM and suggests interventions that enhance women’s exposure to STEM, technical acumen in STEM, or offer STEM community. Identifying what enables women to thrive in STEM is a novel approach to extending these efforts using a strengths-based approach. I thus conducted a case study focused on understanding the experiences of successful women in the STEM workforce. Findings revealed three core characteristics to women’s STEM success: synergizing self and science, science career advancement and mastery, and being a STEM change …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

Disordered Eating And Body Dysmorphic Concerns In Asian American Women: Sociocultural And Culture-Specific Predictors, Liya Akoury

UNLV Theses, Dissertations, Professional Papers, and Capstones

The sociocultural idealization of thinness and Eurocentric features (e.g., lighter skin) is ubiquitous in Westernized cultures, yet only some women internalize these ideals and/or perceive heightened pressures to conform to such ideals. Elevated internalization and perceived pressures to obtain thinness and Eurocentric features may contribute to disordered eating and unique types of body dysmorphic concerns (e.g., dissatisfaction with skin color, eye size/ shape), respectively. Such difficulties may be particularly relevant for ethnic minority women; however, little research exists examining such effects. Further, few studies have comprehensively examined the intersection between sociocultural and culture-specific (e.g., ethnic identity; biculturalism) predictors on disordered …

Face Affect Perception In Schizophrenia And Posttraumatic Stress Disorder, Lisa Beckman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia (SZ) and Posttraumatic Stress Disorder (PTSD) are often comorbid psychological disorders. Separately, research has previously demonstrated deficits in social cognition, including affect recognition impairment in both disorders; however, less is reliably known about the specific deficits unique to a comorbid diagnosis of SZ and PTSD. This study examined the ability to correctly identify facial expressions in individuals diagnosed with SZ (n = 38) and PTSD alone (n = 20), comorbid SZ and PTSD (n = 26), and healthy controls (n = 28). Participants were administered a test battery to establish diagnoses of of schizophrenia and PTSD, and to evaluate …

Identifying Risk Factors For Youth Hospitalization In Crisis Settings: A Classification And Regression Tree Analysis, Yen-Ling Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditionally, treatment option for psychiatric crises was limited to psychiatric hospitalization. However, psychiatric hospitals are expensive and little evidence supports their utility. Youth returning from psychiatric hospitalizations often have difficulties readjusting to everyday life which can increase risk for negative outcomes. Alternative treatment options such as mobile crisis services might be useful for stabilizing youth in the community and garnering better long-term outcomes. For alternative treatment options to work, clinicians must be able to efficiently and accurately distinguish youth in need of psychiatric hospitalization and youth who could be served via an alternative service. Therefore, the purpose of the present …

Reconsolidation: Unique Cognitive Process Or State Dependent Learning?, Chris Kiley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accessing a previously consolidated memory trace brings it back into a labile state where it must then undergo a re-stabilization process known as reconsolidation. During this process memories are susceptible to interference and may be updated with new information. Reconsolidation has been demonstrated in animals as well as in the procedural and episodic human memory systems. However, it is still unclear when the effect will occur. Some studies suggest that reconsolidation is only necessary when new information is presented in the same spatial context or when prediction error occurs. More recent work has provided evidence that reconsolidation could be due …

Exploring The Pristine Inner Experience Of Individuals In Psychotherapy, Alek Emily Krumm

UNLV Theses, Dissertations, Professional Papers, and Capstones

Inner experience is a frequent topic in psychotherapy and in psychology more broadly, yet very little research has carefully and systematically observed the naturally-occurring experience of psychotherapy clients. The current study begins to fill that gap by using descriptive experience sampling (DES) to survey the inner experience of a small sample of individuals seeking psychotherapy. DES is a method that uses a random-interval beeper to signal participants to pay attention to their pristine inner experiences—the thoughts, feelings, sensations, and so on that are directly apprehendable ‘before the footlights of consciousness’—and describe them in high fidelity. We used about eight days …

Assessing Factors Of Physical Risk-Taking In A Novel Behavioral Measure, Edward A. Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Risk taking is a complex heterogeneous construct that has proven difficult to assess, especially when using behavioral tasks. A new measure, the Assessment of Physical Risk Taking (APRT) is presented as a comprehensive assessment of several factors of risk. Specifically, the measure seeks to examine the effects of several decision-making elements (e.g., probability of success and failure, magnitude of reward and punishment) of different types of physically risky behaviors and produce a variety of different outcome scores. Participants (N = 256) completed APRT in a laboratory setting, with half being assigned to an enforced Delay condition. Main effects, two-way interactions …

The Effects Of Sex Role Stereotype Endorsement And Work-Family Conflict On Emerging Adult Aspirations, Andrea Fink-Armold

UNLV Theses, Dissertations, Professional Papers, and Capstones

Workplace and household inequality remain prevalent in the United States and sex role (e.g. breadwinner and caregiver) stereotypes affect the roles that individuals seek out. This research used a mixed-methods approach to investigate the effects of sex role stereotypes and expected work-family conflict on the work and family aspirations of emerging adults. A racially diverse sample wrote freely about their future selves for ten minutes then completed measures to evaluate their sex-role stereotype endorsement, expected work-family conflict, and personal preferences for career and family roles. Results indicate that endorsement of stereotypes predicts increased expectations of work-family conflict, for both men …

College Student Depression: An Examination Of Cardiorespiratory Fitness, Gender And Sexual Orientation Diversity, And Help-Seeking Willingness, Sharon Jalene

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression is a serious illness characterized by persistent low mood, reduced cognitive capacity, and fatigue. Although treatable, depression is the leading cause of disability and ill-health worldwide and a significant contributor to suicide, the second leading cause of death for young Americans. In any given two-week period, 8.1% of adults in the United States had moderate to severe depression (2013-2016). The rate of depression for females was twice that of males and compared to the majority, sexual and gender minorities (SGM) were at a threefold risk. Furthermore, evidence suggests that depression incidence is three times higher in college students than …
