Pathways Through Care Of Latinx Individuals Experiencing First-Episode Psychosis, Estevan Hernandez

Electronic Theses, Projects, and Dissertations

Many individuals experiencing first-episode psychosis (FEP) are unable to work or live independently due to the debilitating nature of their illness. Many individuals experiencing FEP fail to seek mental health treatment for their symptoms. The families of these individuals are often the first to notice early signs of psychosis and seek treatment for the individual (Bridges et al., 2012). there continues to be a high percentage of disengagement from mental health services which may, in turn, contribute to poorer outcomes across various areas in one’s life (Kreyenbuhl et al., 2009). There continues to be a high percentage of disengagement from …

Psychological Distress And Problematic Video Gaming: The Role Of Psychological Inflexibility And Emotion Dysregulation, Frank Nieblas

Electronic Theses, Projects, and Dissertations

Our increasingly technology-driven society has seen a dramatic increase in reports of problematic video gaming. Emerging evidence suggests that psychological distress and avoidance lead to problematic internet use in psychologically vulnerable individuals (Burleigh et al., 2017; Rapinda et al., 2021; Yang et al., 2021). There is also evidence that this process is associated with psychological inflexibility and emotion dysregulation, which are two psychological mechanisms thought to be predictive of maladaptive coping. (Chou et al., 2017; Blasi et al., 2019). Although existing evidence points to a role of uncontrolled processes in maladaptive behavior, psychological mechanisms in which distressed individuals specifically develop …

Impact Of Subjective Cognitive Complaints On Mci Diagnostic Criteria In Alzheimer’S Disease, Rhiannon Rivas

Electronic Theses, Projects, and Dissertations

Alzheimer’s disease (AD) is the most commonly occurring neurodegenerative disease characterized by deficits in patient cognition. Mild cognitive impairment (MCI) is defined as an intermediate stage between cognitively normal (CN) and dementia in which the individual experiences some impairment but can function independently. Gold standard MCI criteria requires a subjective cognitive complaint (SCC) in which a patient acknowledges a decline in cognitive ability, however past findings on its validity as a measure of objective impairment have been inconsistent. Biomarkers found in cerebrospinal fluid (CSF) and indicative of neurodegeneration are also used to examine AD progression. Our study investigates if inclusion …

Adverse Childhood Experiences Effects On Hot And Cool Executive Functioning, Miriam Gabrielle Fenton

Electronic Theses, Projects, and Dissertations

Previous research has shown that adverse childhood experiences (ACEs) are related to executive functioning (EF). However, researchers have yet to explore the differences in hot and cool EF in participants who have experienced ACEs. This current study aims to measure ACEs' effects on EF while distinguishing between hot and cool EF. We did this by administering the WCST, Stroop task, and the Visual Digit Span (backward) to capture cool EF from an undergraduate sample. Additionally, we used the IGT, the emotional Stroop, and Go/No Go (EGNG) tasks to measure hot EF in the same participants. We predicted that participants who …

Children’S Experiences Of Parental Death, “Lost But Still Remembered”, Nour Salem

Dissertations, 2020-current

Parental death is prevalent during childhood, and the emotional, social, and behavioral effects on children’s development are well-documented. Although there is extensive literature on grief in children, most studies on children’s grief have obtained data about children’s experiences though collateral interviews with parents or caregivers, from adults who lost a parent as a child, or through quantitative measures with children and caregivers. Few studies have implemented a qualitative exploration of parental death by asking bereaved children. The objective of the current study was to involve parentally bereaved children in responding to the research question, “what is it like to lose …

The Impact Of Historical Trauma, Self-Compassion, And Resistance Against Racism Among African Americans, Darrick Scott

Graduate Doctoral Dissertations

For African Americans, historical trauma is described as collective psychological, emotional and cognitive distress, producing an intergenerational impact through repeated experiences of oppression that both stems from slavery and continues into the present day through patterned experiences of racism (Williams-Washington & Mills, 2018). The current study explored the association between historical racial trauma, resistance and empowerment against racism, self-compassion, and internalized racism, and symptoms of depression in a sample of 100 African American adults. Due to low internal reliability of the measure, self-compassion in the context of historical trauma could not be examined. The study included exploration of simple correlations, …

A Pandemic’S Potential To Haunt: A Longitudinal Look At The Professional Wellbeing Of Tn’S Infant And Early Childhood Mental Health (Iecmh) Workforce, Robyn A. Dolson

Electronic Theses and Dissertations

Infant and Early Childhood Mental Health (IECMH) providers engage in uniquely relational work with high-risk families that expose them to the full advantages (i.e., compassion satisfaction [CS]) and disadvantages (e.g., burn-out [BO]) of a helper role. Though the pandemic seemed poised to escalate disadvantage, most early pandemic studies found high CS alongside elevated BO. Unfortunately, as COVID-19 has continued, CS has declined while BO has increased. Given the delayed COVID-19 impact on children, these changes may be particularly acute for IECMH providers. Using a longitudinal cohort of 27 IECMH providers, this study aimed to describe and quantify changes in professional …

The Role Of General Mental Ability On A Virtual Reality Prospective Memory Task, Jeanné M. Dube

Psychology and Counseling Theses

Prospective memory is the ability to carry out specific actions at a future point in time. The relationship between prospective memory and general mental ability- otherwise known as intelligence, is complex. Existing prospective memory measures are limited, particularly in regard to their ecological validity. Furthermore, little research has investigated the role of general mental ability on prospective memory performance. In order to build upon extant literature on the prognostic value of general mental ability on prospective memory assessment, this study investigated the extent to which general mental ability relates to adults and older adults ability to complete and virtual-reality based …

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

Graduate Theses and Dissertations

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

Dental Care Utilization Among U.S. Children Participating In Early Head Start Programs, Ahlam Ibraheem Joufi

Health Services Research Dissertations

Early childhood caries (ECC) remains one of the most common preventable diseases among children under the age of 6 years. Several national stakeholders recommend establishing a continuous collaboration of individuals involved with receiving oral health services (dental home) and routine dental care for the child by 12 months. Despite this recommendation, disparities exist among young, low-income children in preventive dental service utilization. The Early Head Start (EHS) program serves low-income children aged 0-3 years and their families and promotes oral health practices and service utilization within the program. This study aims to examine predictors of dental care utilization among children …

Assessing Sexual Minority Women’S Barriers And Facilitators To Seeking And Accessing Mental And Physical Healthcare: A Mixed Methods Study, Charlotte A. Dawson

Psychology Theses & Dissertations

Sexual minority women (SMW) experience greater mental and physical health concerns when compared to heterosexual women. Three key areas of health SMW report these disparities are: mental health, binge eating/body size, and sexual and reproductive health. SMW also report difficulties accessing healthcare in these three areas. An exploratory sequential mixed methods design was utilized to assess barriers and facilitators to healthcare access for young SMW. Study 1 included 20 semi-structured interviews with SMW, resulting in themes of barriers and facilitators identified by participants. These themes were converted into scale items. In Study 2, an expert panel of mental and physical …

Cultural Mechanism Of Mothers' Perceptions Of Youth Psychopathology, Yen-Ling Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cross-cultural research systematically identifies variations in cultural practices, meanings, and responses across different cultural groups. For example, psychiatric symptoms vary in their salience and degree to which they are reported across cultures. Cultural differences in causal attributions likely lead to differences in an individual’s help-seeking intention. However, there are limitations in previous cross-cultural studies about perceptions of psychopathology, including not measuring impairment level and parental distress, as well as the problematic use of categorical variables as predictors. To overcome limitations in previous work, the current project examined the cultural mechanism of mothers’ perceptions of externalizing and internalizing psychopathology in youth. …

The Relationship Between Psychopathy And Sexism Across Self-Report, Vignette, And Novel Dialogue Tree Tasks, Arianne Fisher

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychopathy is a personality construct consisting of a number of traits often associated with what many consider to be the “dark side” of personality. Multiple models and associated measurement tools have been created in an attempt to conceptualize psychopathy, but the field has not reached a consensus in its definition of this construct at this time. Across models, psychopathy is associated with a number of negative attitudes and behaviors, including various forms of prejudice. The relationship between psychopathy and one form of prejudice has not been examined, constituting a serious gap in the literature. This form of prejudice is ambivalent …

Examining The Factor Structures Of The Erq-Ca, Rcads, And Rsca To Identify Unique Predictors Of Ptsd Symptom Clusters In Maltreated Youth, Amanda N. Howard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Youth who have experienced maltreatment have a higher risk of developing posttraumatic disorder (PTSD), which is associated with poorer mental and behavioral health outcomes including emotion dysregulation, anxiety, depression, and lower resiliency. At present, the literature largely focuses on youth who have experienced general trauma or PTSD symptoms, while maltreated youth are vastly understudied. The present investigation was the first study to date to examine the factor structures of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA), the Revised Child Anxiety and Depression Scale (RCADS), and the Resiliency Scale for Children and Adolescents (RSCA) in a sample of maltreated …

Measurement Invariance Of Impact In Bilingual And Monolingual High School Athletes, Hana Cecilia Kuwabara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Given the reported negative consequences of sport related concussion (SRC), establishing the validity of concussion management tools is essential if they are used to determine the severity of concussion, track recovery or decline, implement effective interventions, and assist in return-to-play decision making. Previous research has found cognitive and symptoms differences on ImPACT, the most widely used SRC assessment measure, between monolingual and bilingual student athletes. Before further investigation of these differences can occur, measurement invariance of ImPACT must be established to ensure that differences are not attributable to measurement error. The current study has two aims: 1) to replicate a …

Initial Development And Psychometric Evaluation Of The Mental Health Optimization Checklist (Mhoc), Raymond E. López

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: The Mental Health Optimization Checklist (MHOC) is a proposed measure which utilizes the theory of optimization science to improve mental health outcomes. Psychopathology is typically viewed dichotomously (i.e., does or does not have a disorder) or through cut-off criterion (i.e., 4 out of 5 symptoms, total scores), whereas optimization views psychopathology on a continuum on which patients can optimize factors impacting their mental health. Optimization theory is important for reducing stigma around mental health treatment and the MHOC offers itself as an informative psycho-diagnostic tool.

Methods: An undergraduate student sample (n = 682) completed the MHOC and the Symptom …

Identifying Clinical Profiles In A Community Sample Of Youth With Selective Mutism, Melanie Rede

UNLV Theses, Dissertations, Professional Papers, and Capstones

Selective mutism (SM) refers to a consistent failure to speak in social situations that have an expectation for speaking, despite fluent speech in other situations (American Psychiatric Association, 2013). Recent researchers describe SM as a heterogeneous disorder not always characterized by anxiety (Driessen et al., 2020). Specifically, some have argued that SM may be better explained as a neurodevelopmental rather than an anxiety disorder (Kearney & Rede, 2021). The aim of the present study was to find unique classes for anxiety, oppositional, and communication difficulties among youth with SM. Participants included 129 caregivers of youth with SM aged 6–14 years …

Examination Of Performance Validity And The Relationship To Cognition And Symptoms In Schizophrenia Spectrum Disorders, Erick A. Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Approximately one-in-five individuals with psychotic disorders (i.e., schizophrenia spectrum disorders [SSD]) fail performance validity indicators (PVIs) during neurocognitive testing. Ensuring the validity of neurocognitive test results is necessary if the test scores are to be of use for diagnostic consideration, intervention selection and planning, predicting outcomes, and following changes in cognition over time in response to intervention, spontaneous recovery, or disease progression. PVIs are designed to require only a minimum level of engagement with the evaluation, which means nearly everyone is expected to “pass,” even those with moderate to severe brain damage. Traditional interpretations of PVI failure suggest a noncredible …

The Psychopathology Circumplex+: A Novel Conceptualization Of Psychopathology And Associated Measure, Edward A. Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fearless Dominance (FD) and Impulsive Antisociality (IA) are two personality traits often used in the study of psychopathic personality. FD is characterized by a lack of empathy, resilience to stress, and social potency, while IA is marked by impulsivity, selfishness, and manipulativeness. The current trio of studies sought to expand the use of FD and IA to assess psychopathology more generally. Study 1 consisted of a meta-analysis of all the relationships between FD/IA and various forms of psychopathology. Results affirmed that FD and IA each correlate with a variety of different psychological disorders, each to varying degrees of magnitude, but …

The Impact Of Acculturative Stress On Internalizing Problems Among Racially And Ethnically Minoritized Adolescents And Young Adults In The U.S. : A Systematic Review And Meta-Analysis, Petty Tineo

Theses, Dissertations and Culminating Projects

Due to demographic changes of the U.S. population in the past few decades, more attention has been placed on understanding the sociocultural factors that have an impact on racially and ethnically minoritized (REM) groups and mental health outcomes. One of the factors that has been gaining increased attention in the past few years is acculturative stress. Acculturative stress is associated with various mental health outcomes, such as depression, anxiety, psychological distress, and suicide ideation (SI). However, the magnitude of this association remains unclear. A systematic review and meta-analysis were conducted to provide a comprehensive review of the impact of acculturative …
