Oppositional And Anxiety Behavior Profiles In A Clinical Sample Of Youth With Selective Mutism, Rachele Diliberto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Children with selective mutism often present as a very heterogeneous population, with both anxious (APA, 2000; 2013; Kristensen 2000; Manassis et al., 2007; Steinhausen & Juzi, 1996; Yeganeh et al., 2003) and oppositional symptoms (APA, 2013; Andersson & Thomsen, 1998; Kolvin & Fundudis, 1981; Krohn, Weckstein, & Wright, 1992). This study sought to identify anxiety and oppositional behavior profiles in a clinical sample of children with selective mutism. Also, this study sought to determine both discriminant and concurrent validity for these profiles and examine their association with family expressiveness, conflict and control. Participants (n=57) included youth receiving treatment at the …

Factor Structure Of The Cpt-Ii, Mary Vertinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study investigates the factor structure of the Conners' Continuous Performance Test-II (CPT-II) in four pediatric samples of participants: (a) patients with traumatic brain injury, (b) healthy controls, (c) patients with various clinical diagnoses, and (d) all of the previously mentioned subjects combined. Confirmatory factor analyses (CFA) were used to investigate a one-, three- and four-factor model fit of the data. None of the models examined were an adequate fit for the data; however, it appears that the four-factor model seemed to be the best fitting of the models examined. Failure to find reasonably adequate fit precluded further analyses.

Validation Of A Personality Scale: A Factor Analytic Approach, Leslie Forbush

UNLV Theses, Dissertations, Professional Papers, and Capstones

Researchers and clinicians alike make use of various assessment instruments to investigate variables of interest. These instruments include affective assessments, which require individuals to make judgments about themselves. To make these judgments individuals reflect upon their attitudes, interests, values, and personality traits and choose the corresponding response option that they feel best represents their current status with regards to the variable of interest for each question. The optimal number of response options to be included in such affective measurement scales has been greatly debated over the past several decades (Cox, 1980; Foddy, 1993; Jacoby & Matell, 1971; Jones & Loe, …

Digital Behavior Intervention Plans: Effects On General Education Teacher Fidelity Of Implementation, Christopher G. Holcomb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities often have behavior that interferes with classroom learning. Serious problem behaviors are identified as the most significant factor interfering with learning in the classroom. Unfortunately, chronic behaviors often lead to a student dropping out of school. Current research typically focuses on areas of intervention for these students with little attention towards teacher fidelity of implementation of these interventions. Because of this, student's behavior intervention plans may not show effectiveness (e.g., progress monitoring, data driven decisions). It is important that researchers begin to explore systematic improvements in fidelity of implementation of behavior intervention plan components for general education …

Chinese Outbound Tourists Food Consumption In The U.S.: An Extension Of The Theory Of Planned Behavior, Kaiyang Wu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although Chinese outbound tourists made enormous economic contribution to the U.S. restaurant industry, they seem to have the tendency to consume Chinese cuisine solely during their international trips. This study applies structural equation modeling (SEM) to evaluate different behavioral beliefs' impact on the intentions of Chinese outbound tourist unfamiliar ethnic food consumption in the U.S. Additionally, this research combines the Theory of Planned Behavior (TPB) and food neophobia, a food-related personality trait to better explain Chinese outbound tourists' food rejection behavior in the U.S.

Results of this study showed safety concern, acceptance of table manners, perceived communication gap and food …

Performance Or Processing? Effects Of Levels Of Processing And Divided Attention On Memory-Related Eye Movements, Wei An

UNLV Theses, Dissertations, Professional Papers, and Capstones

Human memories are expressed either with or without consciousness, termed as explicit and implicit memories, respectively. Different encoding manipulations like levels of processing and divided attention have been shown to affect explicit memories but not implicit memories. These dissociations, however, were only found between explicit and implicit item memories. Whether explicit and implicit relational memories will exhibit similar dissociations is still unknown. In order to determine whether explicit and implicit relational memories dissociated in a similar way as explicit and implicit item memories, the levels of processing and divided attention were manipulated in the present study and participants' relational memories …

A Narrative Study Of Male Accompanying Partners: Adaptation To A Nontraditional Role In Dyadic Partnerships, Donald J. Bernard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although the traditional conceptual paradigm of an accompanying spouse, sometimes referred to in social science literature as a trailing partner, emanates from a predominantly female perspective, an emerging trend involves men functioning in that role. With America's changing workforce due to the increased labor force participation of women, a postmodern family structure has emerged as the role of men as breadwinners-in-chief in the traditional nuclear family has been steadily eroded. The academic literature on the traditional pattern of wives trailing their husbands to new geographical for better employment and income is voluminous. However, studies on the emergence of males accompanying …

Who Or What Should I Be Like? The Self-Assessment Of Sexual Desire, Caroline Maykut

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construct of sexual desire has been notoriously difficult to capture and measure, in part as a function of questionable methods of sexual desire assessment. Due to problems finding an accurate, objective marker of sexual desire, research has relied on self-report. One notable difficulty with self-reported desire assessment is the lack of information on the context in which these assessments are made. The only available data focuses on relative assessment of sexual desire within couples, and ignores broader social and cultural contexts. The present study investigated men and women's perception of sexual desire discrepancies between themselves and other people and …

Possible Benefits Of Playing Music Video Games, Amanda Pasinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music video games, such as Rock Band, are an emerging and popular genre of video game that allows non-musicians a taste of what it is like to be a musician. For most people, developing musicianship (or the process of becoming competent with a particular musical instrument) to an expert level is a long and difficult process that can take up to 10 years or over 7,500 hours to complete. Yet musicians tend to outperform non-musicians on a variety of tasks--showing greater motor coordination, better synchronization skills, and better pitch and tempo discrimination--and possibly show differences in related cognitive processes. However, …

Exploring The Inner Experience Of Veterans With Posttraumatic Stress Disorder, Stacy Reger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Military veterans have returned from combat changed by exposure to trauma for as long as history has been recorded. The field of psychology contains a vast literature describing and attempting to understand Posttraumatic Stress Disorder (PTSD) and its detrimental effects on the lives of individuals with the disorder. Despite the volume of study dedicated to PTSD in the literature, in-depth accounts of the lived experience of individuals with PTSD are rare. The current study utilized Descriptive Experience Sampling (DES), a method based on apprehending high-fidelity accounts of momentary inner experience, to explore the inner experience of eight Operation Iraqi Freedom …

Hemispheric Asymmetry In The Perception Of Musical Pitch Structure, Matthew Adam Rosenthal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Both the left and right hemispheres contribute to the perception of pitch structure

in music. Music researchers have attempted to explain the observed asymmetries in the perception of musical pitch structure by characterizing the dominant processing style of each hemisphere. However, no existing characterizations have been able to account for all of the empirical findings. To better explain existing empirical findings, this dissertation characterizes the left hemisphere as dominant in temporal pitch processing (i.e. with respect to the sequential ordering of pitches) and the right hemisphere as dominant in non-temporal pitch processing (i.e. without respect to the sequential ordering of …

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, …

The Presentation Of Childhood Parental Divorce In Adulthood: A Retrospective Phenomenological Study, Sheala Catherine Morrison

UNLV Theses, Dissertations, Professional Papers, and Capstones

There has been a wealth of research aimed at developing an understanding of the way in which the experience of divorce impacts children. However, adult children of divorce have been widely underrepresented in this literature, much of which is outdated being at least ten years old. With shifting societal attitudes and the transformation of the family system since the 1990's it is crucial that the research is updated in order to stay up on the way children and families are impacted in today's society. The purpose of this study was to hear directly from adults who experienced their parents' divorce …

Documenting Nursing And Medical Students’ Stereotypes About Hispanic And American Indian Patients, Meghan G. Bean, Elizabeth S. Focella, Rebecca Covarrubias, Jeff Stone, Gordon B. Moskowitz, Terry A. Badger

Journal of Health Disparities Research and Practice

Objective: Hispanic Americans and American Indians face significant health disparities compared with White Americans. Research suggests that stereotyping of minority patients by members of the medical community is an important antecedent of race and ethnicity-based health disparities. This work has primarily focused on physicians’ perceptions, however, and little research has examined the stereotypes healthcare personnel associate with Hispanic and American Indian patients. The present study assesses: 1) the health-related stereotypes both nursing and medical students hold about Hispanic and American Indian patients, and 2) nursing and medical students’ motivation to treat Hispanic and American Indian patients in an unbiased …

Modeling Hedonic Processing And Anhedonia In Depression, Kevin Mercado

Honors College Theses

Depression is characterized by low positive emotion and a lack of pleasurable experiences, or anhedonia. Past studies have emphasized controlling negative affect, but there is an emerging trend in the depression literature to focus on positive emotion. The current study employed several psychophysiological tools, postauricular reflex, startle blink reflex, and event-related potential (ERP) components such as P3 and the late positive potential (LPP), to assess the dissociable components in positive emotion (consummatory and anticipatory processes). In addition, several different hypotheses of emotional dysfunction were evaluated to accurately model deficits in positive emotionality. A majority of the psychophysiological tools used supported …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 = …
