Client Selected Music Based Effects On Marital And Couples Therapy, Kevin Matthew Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study was designed to examine the interaction of music-based interventions in the therapeutic process of Martial and Couples Therapy. The use of pre-recorded music was found to be under researched within the literature and created a void within the knowledge that clinicians have about how music might enhance effectiveness of treatment. The inclusion of music in this process is not currently known, which led to this study being conducted. Through a phenomenological lens, the awareness and understanding of how clients react and experience pre-recorded music during the therapeutic process, while still having a selection of options to preserve autonomy, …

Effects Of Internalizing Behaviors On Processing Speed And Academic Fluency, Kristen Bjork

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study explored the relationships between internalizing behavior problems, processing speed and academic fluency. Internalizing behaviors are behaviors typically associated with depression and anxiety, such as withdrawal, somatization, and excessive worry. This study focused on the impact of these behaviors on an individual's ability to efficiently process information, as well as perform simple academic tasks quickly. The following measures were used: WISC-IV Coding and Symbol Search scores as a measure of processing speed, WJ-III Tests of Achievement Math Fluency and Reading Fluency scores as measures of academic fluency, and BASC-2 Parent Rating Scale scores for internalizing behaviors. Data gathered from …

Unfinished Business In Bereavement: A Mixed Methods Study, Kara Lee Klingspon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unfinished business(incomplete, unexpressed or unresolved relationship issues with the deceased) is frequently discussed as a risk factor for chronic and severe grief reactions. However, few empirical studies have examined this construct. The present study aimed to address this gap in the literature by examining the presence and severity of unfinished business as well as common themes of unfinished business reported in open-ended qualitative narratives among a sample of 256 bereaved individuals. In bivariate analyses, self-reported presence of unfinished business and the severity of distress due to unfinished business were both found to be associated with higher levels of distress and …

Prison, Perceptions, And Policy: Authoritarianism And Attitudes Toward Sexual Assault Victims In U.S. Correctional Facilities, Amy Michelle Magnus

UNLV Theses, Dissertations, Professional Papers, and Capstones

Existing research on sexual victimization in correctional facilities has expanded since the enactment of the Prison Rape Elimination Act (PREA) of 2003. Previous literature suggests that the prevalence of sexual victimization in prisons is unknown, yet the known ramifications of reported sexual assaults are serious for both the individuals involved and the institution. Government policies such as the Prison Rape Elimination Act (PREA) of 2003 attempt to address the issue of sexual violence in U.S. correctional facilities. Limitations of PREA, however, derive from a lack of clear distinction between coerced and consensual behavior and how these ideas manifest and co-exist …

Impaired Theory Of Mind In Psychotic And Affective Disorders, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychotic symptoms in bipolar I disorder during mood episodes has been associated with several negative outcomes raising the question as to whether psychosis is a risk factor for a more severe form of this chronic and debilitating condition. However, relatively little research has been directed at understanding the relationships among social cognitive functioning in bipolar I disorder with and without a history of psychosis. Impaired social cognition has been identified as a putative endophenotypic markers in schizophrenia and the evidence is mounting as to whether similar impairments also exist in bipolar I disorder. Given the plethora of research supporting the …

Identifying Maltreated Youths At Heightened Risk For Posttraumatic Symptoms, Emma H. Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

Childhood maltreatment is associated with increased risk for lifetime and current PTSD (Davis & Siegel, 2000; Widom, 1999). This study examined a model of PTSD in which dissociation, depression, and posttraumatic cognitions related to heightened PTSD symptoms for maltreated youths. This study then evaluated the model's fit across variations in intelligence, gender, age, ethnicity, and maltreatment type. Participants (n=360) included youths from Department of Family Services-related sites in Las Vegas. The first hypothesis was that the model would display goodness-of-fit across various indices. The second hypothesis was that the model would better fit youths with below average intelligence (FSIQ = …

Weight-Based Microaggressions Experienced By Obese Women In Psychotherapy, Kerri Jo Schafer

UNLV Theses, Dissertations, Professional Papers, and Capstones

A large body of research demonstrates the existence of weight bias in healthcare professionals, including physicians, nurses, and dietitians (Budd, Mariotti, Graff, & Falkenstein, 2011). Very few published studies examine mental health providers' attitudes toward obese clients, but a small body of existing data suggests that mental health providers attribute more negative personal attributes to fictional obese clients and rate them as having more severe symptoms than their average weight counterparts (Agell & Rothblum, 1991; Hassel, Amici, Thurston, & Gorsuch, 2001; Young & Powell, 1985). Given these findings, it is important to understand whether obese clients experience mental health professionals …

Auditory Processing Deficits In Bipolar Disorder With And Without A History Of Psychotic Features, Ryanna Verbiest

UNLV Theses, Dissertations, Professional Papers, and Capstones

Auditory perception deficits have been identified in schizophrenia and linked to dysfunction in primary auditory cortex. There is also evidence that primary auditory cortex abnormalities are associated with positive symptoms, particularly auditory hallucinations. Given the evidence that individuals with bipolar disorder frequently experience auditory hallucinations, it may be that individuals with bipolar disorder who also exhibit psychotic symptoms demonstrate similar impairment in auditory perception tasks. Additionally, these deficits may contribute to impaired social interactions, as they are likely to interfere with accurate perception of emotion from spoken words. The current study examined this matter by comparing performance of 50 individuals …

Reducing Court-Related Stress Through Court Education: Examining Child Witnesses, Attorneys And Parents, Brittnie Turquoise Watkins

UNLV Theses, Dissertations, Professional Papers, and Capstones

Court education presents a useful approach to addressing children's stress, anxiety or fear related to testifying. The current study uses a pretest-posttest design to evaluate whether Kids' Court School (KCS), a court education program in Clark County, Nevada, reduces court-related stress in child witnesses. In addition, attorneys' and parents' concerns related to various elements of the child's impending testimony, are evaluated. The measure used to assess stress was the Court-Related Stress Scale (CRSS), a 10-item Likert scale adapted from the Stressfulness of Life Scale. In addition, open-ended questions were posed at the time of posttest. The CRSS was administered to …

Dual Task Interference In Low-Level Abilities: The Role Of Working Memory And Effects Of Mathematics Anxiety, Alex Michael Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mathematics anxiety is a negative affective reaction to situations involving mathematical thought and is commonly believed to reduce cognitive functioning by impairing the efficient use of working memory resources. The conventional theory describes that the processing disadvantage associated with high levels of math anxiety increasingly impairs performance as working memory demands increase in a math task. Despite this convention, recent reports demonstrate that the high math anxious disadvantage can be measured in tasks that are relatively free of working memory assistance (Maloney, Ansari, & Fugelang, 2011; Maloney, Risko, Ansari, & Fugelsang, 2010). The present study examines these relatively low level …

Development And Testing Of The Home Safety And Beautification Checklist With Mothers Referred For Child Neglect And Substance Abuse, Michelle Pitts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unintentional injury is the leading cause of death among children in the United States accounting for nearly 40 percent of deaths in this age group. Approximately 50 percent of nonfatal injuries, and 40 percent of fatalities, occur in and around the home. Elevated rates of child injury in the home environment are associated with parental substance abuse and neglectful behaviors. Childhood injuries are preventable, yet practical and cost-effective measures to identify child home safety risks are limited. This study involved a retrospective preliminary examination of the Home Safety and Beautification Checklist (HSBC) in a sample of drug-abusing mothers referred by …

Relationship Between Child Behavior Problems, Parental Stress, Child Abuse Potential, And Substance Use Among Mothers In The Child Welfare System, Kendra Tracy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Substance abuse, elevated levels of child behavior problems, and high stress are common among mothers who maltreat their children. However, there is a dearth of research that investigates variables associated with specific types of maltreatment, such as child neglect. Complicating matters, contradictory results between studies have been found among the available research. The present study extends research in this area by investigating the relationships between substance abuse, child behavior problems, parental stress, and child abuse potential in a sample of neglectful mothers with co-occurring substance use disorders. A model is proposed in which parental stress mediates the relationship between child …

An Efficient Standardized Method Of Maintaining Quality Assurance In Therapeutic Treatment Record Keeping, Kelsey Michael Bradshaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Quality assurance (QA) within the field of mental health is the practice of monitoring and reviewing services to ensure adherence to specified standards of care. Agents within State governments and various organizations influence record keeping procedures through ethical guidelines and law. For instance, client records must be maintained for all clients receiving mental health services, including informed consent, releases of information, treatment plans, and progress notes. Accurate and timely record keeping procedures assure quality mental health services. However, professionals sometimes err in the maintenance of client records, which can have a negative impact on services, clients, and practitioners. To assist …

The Effect Of Acute Lps-Induced Immune Activation And Brain Insulin Signaling Disruption In A Diabetic Model Of Alzheimer's Disease, Andrew Scott Murtishaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a neurodegenerative disorder marked by progressive cognitive impairments and pathological hallmarks that include amyloid plaques, neurofibrillary tangles, and neuronal loss. Several well-known mutations exist that lead to early-onset familial AD (fAD). However, these cases only account for a small percentage of total AD cases. The vast majority of AD cases are sporadic in origin (sAD) and are less clearly influenced by a single mutation but rather some combination of genetic and environmental risk.

The etiology of sAD remains unclear but numerous risk factors have been identified that increase the chance of developing AD. Among these risk …

Implicit Theories Of Intelligence And Learning A Novel Mathematics Task, Nathan Oehme Rudig

UNLV Theses, Dissertations, Professional Papers, and Capstones

The social-cognitive model of motivation states that students adopt a theory of the nature of intelligence that guides their goals in academia and their responses to academic setbacks. Students who believe intelligence is an unchanging entity within them are more likely to adopt goals to display high ability, hide low ability, and respond helplessly to failed schoolwork. Conversely, a student who believes intelligence is a measure of effort and persistence will be motivated to gather knowledge and acquire new skills. The current study investigated the role theories of intelligence play in the field of mathematics understanding. In two experiments, participants …

Posttraumatic Stress Disorder In Maltreated Multiracial Youth, Harpreet Kaur

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lemos-Miller and Kearney (2006) first identified depression as a meditator of (1) dissociation and posttraumatic cognitions and (2) PTSD in maltreated children. In addition, they found that African American status weakened the mediating relationship, whereas multiracial status strengthened the mediating relationship. Multiracial youth in Lemos-Miller and Kearney's study experienced a stronger relationship between depression and PTSD than other ethnic groups.

The present study evaluated the Lemos-Miller and Kearney (2006) model of PTSD among a larger sample of multiracial youth. The present study sought to identify whether the Lemos-Miller and Kearney (2006) finding regarding multiracial youth could be replicated. The presented …

Cognitive Differences Between High And Low Responders Of A Tier Ii Reading Intervention, Jillian Cohen

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study evaluated a population of young students with potential reading disabilities who participated in a large western school district's Reading Skills Development project from October 2012 to May 2013. The following questions were addressed: Are there cognitive differences between students who respond well to an intense Tier II reading intervention and those who make little progress? If so, which cognitive skills best discriminate between high and low responders? De-identified data was collected from 171 struggling readers in 1st through 3rd grade who participated in the Reading Skills project. After controlling for English proficiency level, high and low responders were …

Attributions And Coping Behaviors Communicated Among Bullied Students: An Analysis Of Bullying Blogs, Carly Marie Danielson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student bullying is a growing and damaging problem in society today. This study investigates the role of bullied students' attributions and coping strategies through Heider's (1958) attribution theory (AT) and Crick and Dodge's (1994) social information processing model (SIP). Rich data are obtained from bullying blogs that showcase how bullied individuals make sense of their experiences online. The important findings that emerge from this investigation relate to similarities in men's and women's attributions and differences in their coping strategies and resources to manage victimization. Additionally, both men and women experienced similar negative outcomes with particular coping strategies and resources, suggesting …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

School Climate, Absenteeism, And Psychopathology Among Truant Youth, Marisa Charlene Hendron

UNLV Theses, Dissertations, Professional Papers, and Capstones

School refusal behavior has become highly problematic for schools worldwide. Researchers have focused efforts on examining many factors related to absenteeism, including child, parent, family, peer, school, and community variables. Many previous researchers examined absenteeism between groups (i.e. truants vs. nontruants, truants vs. school refusers). The present study investigated percentage of absenteeism in relation to contextual variables in a diverse sample of truants referred to programs designed to improve attendance. First, a model of school climate (Sharing of Resources, Order and Discipline, Parent Involvement, Student Interpersonal Relations, and Student-Teacher Relations) contributing to severity of absenteeism was tested via structural equation …

The Effect Of Early Life Stress On Methamphetamine Damage In The Striatum, Emily Hensleigh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Methamphetamine (METH) abuse impacts the global economy through costs associated with drug enforcement, emergency room visits, and treatment. Hyperthermia is a leading cause of METH induced emergency room visits and may lead to neural damage. Previous research has demonstrated early life stress, such as childhood abuse, increases the likelihood of developing a substance abuse disorder. However, the effects of early life stress on neuronal damage induced by chronic METH administration are unknown. We aimed to elucidate the effects of early life stress on METH induced dopamine damage in the striatum. Animals were separated three hours per day during the first …

A Model Of Hospitality Employee Engagement, Hee Jung Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focuses on employee's state-like psychological resources by investigating individual and organizational antecedents to employee engagement and valued human resource outcomes. The purpose of this study was to develop and test a theoretical model that explains the interrelationships among six constructs and to explore the mediating effects of employee engagement. Structural Equation Modeling using AMOS (18.0) statistical software was used to test the full structural model (measurement and structural model) of the hypothesized relationships among the variables with a sample of hospitality employees. The findings supported all hypothesized relationships except the direct relationship between employee engagement and turnover intention. …

The Mental Organization Of People's Permanent And Situational Attributes, Kathleen Larson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis investigated whether readers would integrate physical descriptions of characters into one coherent mental representation or if they would keep mental representations separate. The integration of multiple concepts has been examined in the context of the fan effect, which is the finding that an increase in the number of learned associations for a concept can result in an increase in retrieval times and error rates (Anderson, 1974). However, there is typically not a fan effect when people are able to organize the related information into a single integrated situation model (Radvansky & Zacks, 1991). Previous studies investigating the fan …

What's Age Got To Do With It? Examining How The Age Of Stimulus Faces Affects Children's Implicit Racial Bias, Erica Cheree Noles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Discrepant results regarding the emergence of children's implicit racial bias suggest additional research is needed to understand the developmental timeline of racial bias. Investigations using established explicit racial bias measures and the implicit association task with children demonstrate racial bias in young children (Aboud, 1988; Baron & Banjai, 2006). These findings do not corroborate the only known developmental use of the affective priming task (APT) to measure racial bias, which suggests implicit racial bias does not emerge until adolescence (Degner & Wentura, 2010). Variations in the task demands, the types of stimuli used to represent the construct of race, and …

Sex In The Brain: The Relationship Between Event Related Potentials And Subjective Sexual Arousal, Taylor Lynn Oliver

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research investigating the relationship between subjective sexual arousal and physiological arousal has focused primarily on measures of genital arousal and has yielded only modest concordance rates between genital and subjective sexual arousal in men, and low concordance rates in women. One of the nagging confounds in the literature, however, has been the fact that different assessment methods are necessitated by men and women's differing genital physiology (i.e., vaginal photoplethysmography in women and penile plethysmography in men). This study sought to investigate the relationship between subjective sexual arousal and a different type of physical arousal (brain activation) that could be measured …

The Role Of Self-Concept In Consumer Behavior, Marisa Toth

UNLV Theses, Dissertations, Professional Papers, and Capstones

Understanding the influences underlying consumption has become an increasingly important goal for marketers. This study examined the role of self-concept in consumer behavior, specifically product evaluation. The influences of various dimensions of the self-concept are examined in regard to four product dimensions: public luxury, public necessity, private luxury, and private necessity. Differences due to variations in individual levels of self-monitoring are also measured. Overall, results showed that the more conspicuous a product is (higher on luxury/public dimensions) the greater the relationship between evaluation and ideal self-images (ideal self and ideal social self) for both high and low self-monitors.

Family Environment And Severity Of Absenteeism In Youth, Rachel Marie Loftis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the relationship between family environment and severity of youth absenteeism in clinical and community settings. Previous researchers have adopted a categorical approach to investigating the role of family environment in problematic absenteeism by diving youth into discrete categories and these studies are almost exclusively conducted in clinical settings. The current study contributes to the literature by adopting a dimensional approach that examines the impact of family environment on problematic absenteeism across diagnostic and functional categories.

The first aim of the study was to determine the family environment characteristics most predictive of absenteeism severity. The first hypothesis …

Wisc-Iv Profiles In Children With Attention Deficit Hyperactivity Disorder And Comorbid Learning Disabilities, Elyse Parke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention Deficit Hyperactivity Disorder (ADHD) and learning disabilities (LD), including Reading Disorder (RD), Disorder of Written Expression (DWE), and Developmental Coordination Disorder (DCD) all co-occur at high rates. Previous research indicates increased neurocognitive impairment in ADHD with the presence of comorbid diagnoses. However, few direct comparisons between intellectual profiles of children with one or multiple ADHD and LD diagnoses are available, specifically for the Wechsler Intelligence Scale Fourth Edition (WISC-IV), despite its frequent and historical use with this population. Profile analysis may contribute insights into spared and impaired abilities. Therefore, the present study addressed these matters by comparing WISC-IV profiles …

Dehumanization: As It Is Present Within Bullying Behaviors In An Anti-Bullying Program, Katelyn Amos

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bullying is an aggressive act performed repeatedly on another enacting a power differential. This thesis utilized data collected from The Anti-Bullying Prevention Pilot Program (ABPPP), which studied bullying within eleven schools in a large metropolitan area in southwestern United States. The program was aimed to increase positive school climate through the use of Operation Respect and Welcoming Schools programs.

Consensual Qualitative Research (CQR) and mixed methods approaches were used in order to analyze interviews and questionnaires. Grounded Theory analysis procedures were used to code the information, and thick descriptions were utilized to illustrate the occurrence of dehumanization among across four …

Examining The Relationships Between Internalizing And Externalizing Problems And Academic Achievement, Lara Elizabeth Conrad

UNLV Theses, Dissertations, Professional Papers, and Capstones

The relationship between internalizing and externalizing problems and academic achievement for children and adolescents has been inconclusive. Particularly the relationship between the Behavior Assessment System for Children, Second Edition (BASC-2) reports of internalizing and externalizing problems and academic performance on the Woodcock-Johnson, Tests of Achievement, Third Edition (WJ-III:ACH). The current study examined the self and parent reports of internalizing and externalizing problems as measured by the BASC-2 and the relationship with academic skills as measured by the WJ-III:ACH. The referral source (private practice or school setting) was evaluated for severity of presenting internalizing and externalizing symptoms. Secondary data analysis was …
