Do Loneliness And Social Isolation Predict Mortality Because Of Hazardous Drinking?, Jussi Tanskanen, Sarah N. Arpin, Cynthia D. Mohr

Psychology Faculty Publications and Presentations

Introduction: Subjective feelings of loneliness and objective social isolation have been consistently connected with ill-health and mortality, though little work has empirically examined the mechanisms explaining the adverse effects. This study examines whether alcohol consumption explains the connection of loneliness and social isolation on mortality in different age and gender groups.

Methods: The sample comprised a representative 1994 Finnish sample (n = 8,650) matched with 22-year follow-up mortality data. A multigroup path analysis with discrete survival time analyses was conducted.

Results: There were unique differences in the associations between loneliness, social isolation, alcohol consumption, and mortality based on age and …

The Importance Of Acquisition Learning On Nicotine And Varenicline Drug Substitution In A Drug-Discriminated Goal-Tracking Task, Brady M. Thompson, Scott T. Barrett, Y. Wendy Huynh, David A. Kwan, Jennifer E. Murray, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine and varenicline (Chantix®; the leading non-nicotine cessation pharmacotherapy) can come to control appetitive behaviors such as goal-tracking. We tested rats (N = 48) in a drug-discriminated goal-tracking (DGT) task where each rat received daily subcutaneous injections of either nicotine (0.4 mg/kg) or saline (0.9% [w/v]) interspersed across the acquisition phase (Phase 1). On saline days, sucrose was intermittently available. On nicotine days, sucrose was withheld. All rats acquired the discrimination with increased goal-tracking rates on saline days relative to nicotine days. Following acquisition, rats were separated into four groups to assess drug-substitution and discrimination reversal in Phase 2. The …

The Relationship Between Status Motives And Social Activism, Olajuwon Olagbegi

Honors Theses

Numerous social and cultural events have resulted in increased interest and participation in social activism in the United States, stemming from mounting dissatisfaction with social inequality. Though explanations have previously included increased issue exposure and awareness due to the proliferation of digital media and increases in progressive ideology amongst the nation’s younger generation, the current study tests the hypothesis that social activism may in part be motivated by interest in status acquisition, given the evolutionary value of status for securing access to resources and mates. To test this hypothesis, participants were randomly assigned to a status versus control priming condition …

Social Cognition, Impulsivity, And Emotion Regulation Factors In Aggressive Behavior Among Children With Attention-Deficit/Hyperactivity Disorder., Kelly E. Slaughter

Electronic Theses and Dissertations

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) exhibit greater levels of aggressive behavior than their typically developing peers, often resulting in impairment in social and family functioning. Aggressive behavior is often differentiated into two functions: reactive, or “hot-blooded” and proactive, or “cold-blooded” aggression. Prior research has identified several factors contributing to aggressive behavior within a general population, including emotion dysregulation, negative urgency, social information processing (SIP), and parenting behaviors. A paucity of research has examined these factors within an ADHD population. Thus, the present study aimed to examine social, emotional, behavioral, and cognitive factors associated with aggression among children with ADHD. Specifically, …

Building A Repertoire Of Joint Attention Bids In Children With Autism, Erica Jordan Rackers

Graduate Theses/Dissertations

The current study extended previous research through evaluating if a multiple-probe procedure including auditory scripts and script-fading procedures could build a generalized repertoire of initiating bids for joint attention in three young children with autism. Stimuli were selected from four categories. Three categories were associated with teaching procedures and within-category generalization. The fourth category was associated with across-category generalization. The four categories were (a) visually alluring toys, (b) strangely placed objects, (c) large pictures, and (d) sounds. Category assignments in which teaching procedures or generalization were assessed were counterbalanced across the participants. Three different auditory scripts were selected and used …

Nicu Experiences Of Adoptive Parents & Desired Preparation, Catherine J. Howe

Graduate Theses/Dissertations

Parents who have newborns admitted into the Neonatal Intensive Care Unit (NICU) have multiple experiences and emotions. Additional social and emotional layers are experienced by adoptive couples when the infant they wish to adopt needs specialized care. This research study was completed to find out what adoptive parents experience in the NICU and what preparation would have been helpful. The method included semi-structured, open-ended interviews with seven couples who adopted a newborn at a Midwestern adoption agency within the past three years and had a NICU experience. The results described adoptive couples’ experiences on the unit, bonding and attachment, fears …

Tavr In Older Adults: Moving Toward A Comprehensive Geriatric Assessment And Away From Chronological Age: Jacc Family Series, Joy M Schmitz, Scott D Lane, Michael F Weaver, Ponnada A Narayana, Khader M Hasan, Delisa D Russell, Robert Suchting, Charles E Green

Faculty, Staff and Student Publications

Cocaine use continues to be a significant public health problem with limited treatment options and no approved pharmacotherapies. Cognitive-behavioral therapy (CBT) remains the mainstay treatment for preventing relapse, however, people with chronic cocaine use display cognitive impairments that are associated with poor response to CBT. Emerging evidence in animal and human studies suggests that the peroxisome proliferator-activated receptor-gamma (PPAR- γ) agonist, pioglitazone, improves white matter integrity that is essential for cognitive function. This project will determine whether adjunctive use of pioglitazone enhances the effect of CBT in preventing relapse during the early phase of recovery from cocaine use disorder. This …

Identifying Risk Factors For Ptsd Symptom Clusters In Maltreated, Multiracial Youth Using Nonparametric Modeling, Mallory Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Multiracial youth are one of the most at-risk racial groups for child maltreatment. Multiracial individuals are also more likely to report mental health concerns than other racial or ethnic groups. This study aimed to identify demographic and psychological risk factors that are unique to multiracial, maltreated youth with respect to PTSD symptoms (i.e., re-experiencing, hyperarousal, avoidance) through classification and regression tree (CART) analyses. Participants included 99 multiracial, maltreated youth directly following their placement in an emergency group shelter due to substantiated maltreatment. The first hypothesis was that female gender, English first language, questions related to guilt and self-blame, and depressive …

Feasibility And Efficacy Of Virtual Darkness In Reducing Intra-Individual Sleep Variability Among Young Adults With Insomnia, Samantha Nicole Sherwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

BackgroundInsomnia impacts 30% of people and is associated with increased risk for medical and psychiatric illness. However, pharmacological treatments for sleep yield mixed results and often result in undesirable side effects indicating a need for novel insomnia interventions. Sleep patterns also demonstrate high intra-individual variability which may be associated with greater daytime impairment, and sleep-wake cycles are strongly affected by the timing of exposure to blue-green wavelength light. Virtual darkness, a novel intervention, blocks blue wavelength light from reaching the eye to simulate actual darkness on retinal cells sensitive to light. Therefore, the purpose of the current study is to …

Support For Militant U.S. Foreign Policy: The Role Of Authoritarianism And International Xenophobia, Brandon M. Garcia

Student Theses

Right-Wing Authoritarianism (RWA) has been studied extensively in the domestic socio-political context, but its potential impact on foreign policy is still poorly understood. The current study replicated the putative two-factor model of the construct (Authoritarian Aggression/Submission and Conventionalism) and examined the associations of each factor with perceptions of overall danger to the U.S. posed by other countries and with the support for more militant U.S. foreign policy. As expected, both RWA factors correlated with self-reported levels of political conservatism (r = 0.32, r = 0.33; p < .001) Additionally, Authoritarian Aggression and Submission (but not Conventionalism) were correlated with increased perceived danger from foreign countries (r = .35; p < .001) and increased support for a more militant U.S. foreign policy (r = .25; p < .001). Participants higher in RWA were more likely to view the world as a hostile and threatening place, and in turn support more aggressive military action in response to those fears.

Improving Stress Management For Female College Students, Kelsey Acosta

Capstone Projects and Master's Theses

Although many college students report feeling stress, women may have a unique perspective and experience regarding stress. Gilligan's theory states that women consider their relationships when considering decisions. This decision-making process can create an added layer of the already existing academic stressors that women face. Stress management techniques that acknowledge the unique stressors that women face are essential to improve mental health and provide an optimal college experience.

Brevity Vs. Breadth: Can Memory Disorders Be Diagnosed Using Fewer Neuropsychological Assessments?, Analise Roccaforte

Theses and Dissertations

Object: The present study examines the clinical utility of combining a cognitive screener, Montreal Cognitive Assessment (MoCA), with a measure of adaptive functioning, Texas Functional Living Scale (TFLS), to diagnose memory disorders when differentiating between cognition within normal limits (WNL), mild cognitive impairment (MCI), and Alzheimer’s disease (AD). Method: A total of 207 Health First Memory Disorder Clinic patients, ages 64-94, were included in the study. Participants were screened using the MoCA and then they completed a brief neuropsychological evaluation, which included the TFLS. Participants were only included if they received a diagnosis of cognition WNL, MCI, or AD. They …

Utilizing The Radsm Process: Developing An Unobtrusive Measure Of Cohesion, Zachary Lee Rahner

Theses and Dissertations

In this study, verbal indicators produced following the RADSM process were used to code transcript data collected from 62 three-person teams playing a cooperative bridge crew simulator. A training dataset, consisting of 88 mission transcripts, and a testing dataset, consisting of 39 mission transcripts, were created from the data. Multilevel modeling was employed to develop a linear-regression algorithm to predict/measure team task and social cohesion. The findings revealed that task cohesion perceptions are linked to the proportion of speech dedicated to information requests and instructions, whereas social cohesion perceptions are associated with the proportion of speech dedicated to amusing and …

Undergraduate Honors Theses

Introduction. Prior research has found high rates of behavioral health concerns, including several forms of substance use, among community college students. However, the prevalence of non-medical use of prescription stimulants (NMUS) as well as the motivations driving NMUS among community college students is unknown. Methods. Survey results from 13 community colleges within the Tennessee Board of Regents school system were evaluated to explore 1) rates of NMUS, 2) reported motivations for NMUS, and 3) how demographic characteristics including race, age, and income differ based on self-reported reasons for NMUS. Results. NMUS was reported by approximately 9% of the overall sample. …

Household Responsibilities And Experiences Of Work-Family Conflict And Well-Being Among Fathers: The Role Of Identity And Gender Role Beliefs, Rita Garcia

Electronic Theses, Projects, and Dissertations

Dual earner families are on a rise and there has been an increase of men participating in household responsibilities. Gender roles ideologies and identity salience influence how the division of labor is distributed within a household and may relate to work-family conflict in fathers when participating more in household responsibilities. The purpose of the present study was to examine the impact of household responsibilities on working fathers’ experiences of work-family conflict and well-being, and to consider potential moderating effects of gender role ideology and identity salience. Results supported a positive relationship between household responsibilities and perceived stress in working fathers. …

Optimism And Physical Health-Related Quality Of Life In Chronic Illness: Mediating Effects Of Control Beliefs And Health Behaviors, Morgan Treaster

Electronic Theses and Dissertations

Among persons living with, or recovering from, chronic illness, poor physical health-related quality of life is a concern, as current and residual illness symptoms and treatment side effects may deleteriously impact physical functioning and fulfillment of daily roles. Numerous cognitive, emotional, and behavioral factors may impact perceptions of health status. Optimism, for example, is conceptualized as belief in the occurrence of positive future outcomes, and is beneficially associated with physical health-related quality of life. Further, optimism may contribute to enhanced perceptions of control and efficacy over disease symptoms and general health, manifesting as proactive health behaviors (e.g., wellness behaviors; treatment …

Evaluating Nebraska Ems Providers' Ability And Willingness To Respond To Bioterrorism Emergencies, Ryan Houser

Capstone Experience: Master of Public Health

UNLV Theses, Dissertations, Professional Papers, and Capstones

The resurgence of social movements such as Black Lives Matter has provoked public discourse about racial inequality and efforts towards social change. The current study sought to better understand how young adults reason about racism reduction with a focus on racial allyship and collective action. The present study used mixed methods to identify strategies young adults believe different racial groups could do to reduce racism and investigate the influence that individual factors have on reasoning about social change. Here, I present emergent themes to describe racism reduction strategies from a large and racially diverse sample of undergraduate students (N= 428). …

Racial/Ethnic Disparities In Mental Health Diagnosis Of Maltreated Youth, Shadie Burke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Racial/ethnic marginalized youth are more likely to receive a misdiagnosis of a mental health disorder than their White peers. Misdiagnosis contributes to existing disparities for racial/ethnic marginalized groups by leading to longer durations of untreated and worsening mental health symptoms. For maltreated youth, receiving a misdiagnosis can lead to a failure to connect with appropriate mental health services, medication regimens, therapeutic foster homes, and academic and developmental resources. To date, very few empirical studies have identified disparities in mental health diagnosis among racial/ethnic marginalized maltreated youth. The present study examined two key research questions: (1) what racial/ethnic disparities in diagnoses …

Youth Mental Health Service Preferences And Utilization Patterns Among Latinx Caregivers, Alejandro L. Vázquez, María De La Caridad Alvarez, Cynthia M. Navarro Flores, José Manuel González Vera, Tyson S. Barrett, Melanie M. Domenech Rodríguez

Psychology Faculty Publications

Latinx caregivers underutilize traditional youth mental health services (MHS) relative to their White counterparts. Disparities may be explained by barriers preventing engagement in traditional MHS. A potential mismatch between available services and preferred culturally appropriate healing practices may also contribute to treatment disparities. The current study examined Latinx caregivers’ perceived need for and utilization of support services in relation to family characteristics, youth problem-type, and barriers to care. Findings were contextualized by assessing caregiver preferences for addressing youth psychopathology. The study consisted of 598 Latinx caregivers from across the United States. Descriptive statistics and binary logistic regression models were used …

Does Bedtime Music Listening Improve Subjective Sleep Quality And Next-Morning Well-Being In Young Adults? A Randomized Cross-Over Trial, Nadyana M. Majeed, Verity Y. Q. Lua, Jun Sen Chong, Zoey Lew, Andree Hartanto

Research Collection School of Social Sciences

Previous research has found that young adults exhibit patterns of poor sleep and that poor sleep is associated with a host of negative psychological consequences. One potential intervention to improve sleep quality is listening to music at bedtime. Although there exist previous works investigating the efficacy of listening to music as a form of sleep aid, these works have been hindered by statistically weak designs, a lack of systematic investigation of critical characteristics of music that may affect its efficacy, and limited generalizability. In light of the limitations in the existing literature, a 15-day randomized cross-over trial was carried out …

Long-Term Effects Of Adolescent Fluoxetine Exposure On Hippocampal Gene Expression In Male C57bl/6 Mice, Anapaula Themann

Open Access Theses & Dissertations

Mood-related disorders, including depression and anxiety, are prevalent among children and adolescents. This poses a public health challenge, given their adverse impact on these young populations. Treatment with the selective serotonin reuptake inhibitor fluoxetine (FLX) is the first line of pharmacological intervention in pediatric patients suffering from affect-related illnesses. Although the use of this antidepressant has been deemed efficacious in the juvenile population, the enduring neurobiological consequences of adolescent FLX exposure are not well understood. For this reason, we explored for persistent molecular adaptations, in the adult hippocampus, as a function of adolescent FLX pretreatment. To do this, we administered …

Student Attitudes Toward Science: Growth Trajectories And Thematic Analysis Of A Project-Based Internship, Robert Donavin Mccreary

Open Access Theses & Dissertations

In order to increase the number of students pursuing science-related careers, science educators and policymakers have advocated for improving student attitudes toward science (SAS) through inquiry-based instruction, such as project-based learning (PBL). While challenges exist in PBL, research suggests cogenerative dialogue (cogen) can ease the transition for students from traditional learning to PBL. In the present study, a secondary analysis was conducted to examine SAS growth trajectories from participants of the Work With A Scientist Program (WWASP) – a student-scientist internship which integrated cogen with PBL. Additionally, a thematic analysis was conducted to explore student attitudes toward cogen. The growth …

Does Whispering Improve Children’S Memory? Comparing Auditory Vigilance And Salience Hypotheses, Christina M. Barnes

Graduate Theses and Dissertations

Oral communication is one of the primary tools children use to learn new information and speech registers can deliver additional meaning to the words someone uses. Cirillo’s (2004) vigilance hypothesis states “Whispering can affect the psychobiological state of recipients, and in particular raise their auditory vigilance” (Cirillo, 2004, p. 76). Building on this theory, the current study investigates the role of whispering and children’s memory by examining a whispering vigilance, whispering salience which focused on the changes between normal and whisper registers, and combined vigilance and salience hypotheses to determine if whispering contributes to the recall of information. Using video …

Sleeping With The Enemy: Examining The Relationship Between Sleep And Pain In Post-9/11 Veterans, John L. Schwartz Jr.

Psychology Theses & Dissertations

United States veterans are a diverse group of individuals, yet as a result of their service, they share a unique set of customs, traditions, and values. Post-9/11 veterans are more likely to experience elevated levels of pain and poor sleep quality compared to their civilian counterparts; however, little is known about how beliefs related to veterans’ pain impact their sleep and how levels of pain acceptance influence the sleep-pain association. This study examined relationships between sleep and pain in a sample of 102 post-9/11 veterans. Results support associations between pain and sleep identified in other populations. Positive correlations were found …

Intention-Behavior Discrepancies For Alcohol Consumption Among College Students, Emily Kaye Junkin

Psychology Theses & Dissertations

Unplanned drinkers may experience elevated risk for drinking-related harm. Research examining unplanned drinking focuses on the unplanned nature of a drinking episode (i.e., did the student drink when no drinking was planned), yet this does not capture the importance of the unintended quantity consumed. For instance, a discrepancy between drinking intentions and actual consumption has the potential to differentially impact alcohol-related outcomes beyond what is accounted for by unplanned drinking episodes. Further, research has not investigated how college students’ unintended drinking is associated with alcohol-related consequences. Moreover, utilization of protective behavioral strategies (PBS) has been shown to decrease negative outcomes …

The Influence Of Emotion Regulation And Neural Cognitive Control On Distress Tolerance, Alicia L. Milam

Psychology Theses & Dissertations

Tolerance of negative emotions has been associated with transdiagnostic negative mental health outcomes. Theory and research implicate emotion regulation and cognitive control as factors in tolerance of negative emotions. But their unique contributions to tolerance of negative emotions and interdependency have been unclear due to methodological limitations. This study aimed to explicate cognitive and emotional factors affecting distress tolerance in a non-clinical sample of emerging adults. Undergraduate psychology students completed self-report measures of emotion regulation ability and tolerance of negative emotions. The N2 ERP component elicited by a Go-NoGo task was also used as a neurophysiological marker of cognitive control …

The Effects Of Depression, Anxiety, And Stress On College Students: Examining The Role Of Mental Health Self-Efficacy On Willingness To Engage In Mental Health Services, Leeanna L. Golembiewski

Psychology Theses & Dissertations

Relative to younger ages, mental health problems are more prevalent among college students (Pedrelli et al., 2015) and nearly 20% of U.S college students are diagnosed each year with a mental health problem (Blanco et al., 2008). College students’ self-efficacy may influence mental health outcomes by impacting an individual’s decision to change their behavior and execute a course of action (Bresó et al., 2011). Mental health may also be influenced by the degree of willingness that an individual possesses, such that those who are more willing to seek mental health treatment are also more likely to follow through and seek …
