Course Of Disease Progression And Time To Death Among Different Dementia Types In A Population Based Study, Kaitlyn E. Kauzor

All Graduate Theses and Dissertations, Fall 2023 to Present

Alzheimer’s disease (AD) is the most common type of dementia, Other types of dementia include vascular (VaD) and mixed forms, like AD with VaD, other mixed forms of dementia or dementia of unknown etiology (DUE). Research has focused on factors that may increase risk of developing dementia, with less understood about disease course. Factors associated with risk for developing dementia onset include age, female sex, family history of dementia, genetics (e.g. having the ε4 allele of the Apolipoprotein E or APOE gene), and various health conditions. This project used previously collected data from the Cache County Study on Memory and …

Script Fading And Training: Evaluating The Necessity Of Visual Cues To Teach Contextually Appropriate Play Commenting, Devanio J. Cousins

All Graduate Theses and Dissertations, Fall 2023 to Present

Autism Spectrum Disorder (ASD) is marked by many areas of need, including play and communication. These areas of concern can have a negative impact on a child's development. Applied behavior analysis, specifically script training and fading procedures, has shown promise in teaching communication during play to young autistic children. However, traditional script training and fading methods have some limitations, including the skills the children already possess to learn the scripts and the resources needed to teach the scripts. Recent studies have shown that script frames can be taught without using traditional training formats (i.e., text, auditory) but by using generic …

The Informal, Non-Prescribed Use Of Antiretroviral Medications For Prep Among A National Us-Based Sample Of Gay, Bisexual, And Other Men Who Have Sex With Men: A Cross-Sectional Study, Mance E. Buttram, Matthew S. Ellis, Krishen D. Samuel, Matthew Hayhurst

Health, Human Performance and Recreation Faculty Publications and Presentations

This brief report presents findings on informal, non-prescribed PrEP use among an online sample of gay, bisexual and other men who have sex with men (n = 196). Mean age was 33.4. Participants were Hispanic (13.3%), African American (15.8%), white (63.8%), and other race/ethnicity (6.6%). Informal PrEP users (11%) more frequently reported past year sexually transmitted infections (p < 0.001), group sex (p < 0.001), sex in public (p < 0.01), transactional sex (p < 0.001), ever receiving a formal PrEP prescription (p < 0.05), and ease of finding diverted HIV medications on gay dating/sex apps (p < 0.05). Formal PrEP uptake should be encouraged to mitigate potential negative consequences of informal use.

The Lasting Psychological Effects Of Juvenile Arrests, Nadia Olivia Bortolin

Theses and Dissertations

This research investigated the enduring psychological consequences, specifically depression and anxiety, stemming from juvenile arrests and their influence on adulthood. Literature has demonstrated impacts on juvenile arrests from cultural, socioeconomic, family dynamics, and environmental elements. This study addresses a notable gap in understanding the long-term impact on mental health and employment. Research indicates a sensitivity to outcomes based on the age of arrest, with early adolescent arrests having profound effects on development and an increased likelihood of subsequent criminal activities. Developmental and risk factors, such as socioeconomic challenges and pubescent difficulties, contribute to persistent delinquent behaviors into adulthood. Some studies …

Democratizing The Early Identification Of Alzheimer's Disease And Access To Care: The Role Of Psychologists In Brief Assessment, Jacqueline S. Hogan

Graduate Doctoral Dissertations

As Alzheimer’s disease (AD) presents a growing public health challenge, accessible early detection tools are urgently needed. This study used data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) (N = 1,536) to evaluate the ability of machine learning models to predict a conversion from normal cognition or mild cognitive impairment (MCI) to AD. A brief neuropsychological battery, including the Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS13), Mini-Mental State Examination (MMSE), Rey Auditory Verbal Learning Test (RAVLT), and Functional Activities Questionnaire (FAQ), was employed. The Gradient Boosted Trees model demonstrated superior performance, achieving an F1 score of 0.88, recall of 0.93, precision …

Organizational Toxicity: Exploring Factors That Cultivate Toxicity In Air Force Maintenance Organizations And Their Impact On Enlisted Airmen, Bryan Keith Wong

Electronic Theses and Dissertations

Workplace toxicity negatively impacts organizations and harms employees within those organizations. However, each organization is subject to various influences and contexts, and understanding toxicity within specific contexts provides practitioners with the knowledge of its origin, influential factors, and how to respond. The U.S. Air Force is rich in culture and subcultures; it is also subject to toxicity, which is affected by several military-unique factors. Yet, toxicity in the military has been primarily explored through the leadership lens with limited insights into other influential elements, such as followers and the workplace environment. Additionally, little attention has been placed on the effects …

Effect Of Epistemic Cognition And Self-Regulation On The Evaluation Of Online Information, Devin T. Foschi

UNLV Theses, Dissertations, Professional Papers, and Capstones

While research has shown that epistemic cognition plays an important role in self-regulation, the way in which it does so in online contexts needs further research. The objective of this dissertation was to examine the relationship between Internet-specific epistemic cognition and Internet-specific self-regulated learning, and to use a mixed-methods approach in order to expand upon the way learners undergo the evaluation of information in online spaces beyond the traditional method of only using self-report measures and other common quantitative techniques. Using an explanatory sequential mixed-methods design, Phase 1 (N = 117) used quantitative methods to first look at the relationship …

Symptom Network Comparisons Between Pre- And Post-Concussion, Christine Salva

UNLV Theses, Dissertations, Professional Papers, and Capstones

Increased awareness about the short and long-term negative outcomes associated with sport-related concussion has resulted in active monitoring of cognitive and symptom profiles of athletes using a variety of assessments. The traditional approach to interpretation of cognitive and symptom measures has been based on a latent construct framework where domain scores reflecting latent constructs representing cognitive or symptom domains are collected at baseline and then compared to those obtained after concussion during the acute injury phase, with repeated additional assessments to determine when cognitive and symptom alterations have resolved. More recently, network approaches have been used to examine changes in …

Appearance Investment And Intimacy: Direct And Indirect Effects In The Context Of Romantic Relationships, Lillian P. Palmer, Setareh M. Rossman, James Cordova

Psychology

Physical appearance is highly valued in Western society and has the potential to impact many domains of personal life, including romantic relationships. This study examined the direct effect of appearance investment on intimacy and indirect effects through perfectionist self-presentation presentation and relationship mindfulness, utilizing a Structural Equation Model approach. Appearance schemas are cognitive generalizations about the importance of physical appearance within one’s self-concept and contribute to cognitive and behavioral investment in appearance. Concern for appearance influences how individuals interact with others and process the world around them, thus it has the potential to influence relationship health. However, no study to …

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The initial transition to college is a pivotal moment for emerging adults, often influencing whether a student will remain successful. Students face a significant challenge adapting to the new environment that has been compounded by their experiences through the COVID-19 pandemic. Despite these challenges, a sense of belonging for students has been shown to be a key aspect of a successful transition to college. Students are often confronted with increasing levels of mental health challenges throughout the transition, specifically experiencing increasing mental health difficulties or challenges throughout their initial adjustment to college. Moreover, parents have become increasingly involved in students’ …

An Integrative, Systematic Review Of The Situational Judgment Test Literature, Sven Kepes, Sheila K. Keener, Filip Lievens, Michael A. Mcdaniel

Research Collection Lee Kong Chian School Of Business

Situational judgment tests (SJTs) are popular assessment approaches that present scenarios describing situations that one may experience in a job. Due to its long history and cross-disciplinary nature, today’s SJT literature is quite fragmented. In this integrative review, we start by systematically taking stock and synthesizing the SJT literature from the different scientific disciplines via bibliometric techniques on 524 unique documents. We identify six literature clusters (i.e., SJTs in the medical sciences, SJTs in personnel selection, methodological issues and SJTs for specific constructs, SJTs to assess emotional intelligence and related constructs, technological advances in SJTs, SJTs for teacher assessment and …

Research Collection Lee Kong Chian School Of Business

Objective: Investigate short-term personality development during the post-graduation transition. Background: Prior research indicates that long-term personality development matters for employment outcomes. However, this evidence is primarily limited to multi-year longitudinal studies. This research switches the focus to personality changes during a shorter, impactful life transition. Method: We examined how short-term personality development during the 14-month post-graduation transition relates to early career outcomes among two diverse samples of graduates from universities (N = 816) and community colleges (N = 567). We used latent growth curve models to examine associations between career outcomes measured 14 months after graduation with initial personality levels …

Appreciative Inquiry: Guiding Principles For Majority And Minority World Teams Conducting Research In Majority World Countries, Kendall Cotton Bronk, Lindsey C. Blom, Seren Fryatt, Flomo Mau Maiwo, Yabadel Appleton

Journal of Youth Development

The vast majority of youth development research takes place in minority world cultural contexts. To understand and nurture the optimal development of young people living in majority world countries, cross-cultural research teams are uniquely suited to conduct careful and culturally sensitive research in these settings. However, this is difficult. Navigating research in a new language, a different cultural context, and a far-away geographic location is challenging, and the risks of getting it wrong are high. We argue that the guiding principles of Appreciative Inquiry can help teams navigate many of the challenges inherent in conducting youth development research in majority …

From “At-Risk” To “Aspiring” Youth:Locating Positive Youth Development In Kenya, Kennedy Karani Onyiko, Justine Amadi Orucho, Lawrence Asige, Dennis Omuse Obushe, Aden Ang'aba Esokomi, Faith Inyele Olita, Simon Kitiyo

Journal of Youth Development

The youth population bulge in Kenya comes with so many challenges such as poverty, gender inequalities, political inequities, the absence of adequate health and medical resources, low educational attainment, homelessness, increased involvement in violence, drugs, and alcohol, poor physical and mental health, a lack of key life skills, premature sexual involvement. Using inductive or “bottom up” thematic analysis, we explored experiences of the youth aged 18-34 (n=36), youth workers (n=26) and administrators of youth programs (n=22) on existing youth development programs and their alignment to the positive youth development principles. Six key findings from the study sufficed as follows: (1) …

The Association Between Sports Camp Participation And Perceivedcompetence And Independence Among Visually Impaired Youth, Mary A. Keene, Justin Haegele, Xihe Zhu

Journal of Youth Development

Research on sport camps for visually impaired youth is limited. The purposes of this study were to examine if visually impaired campers’ self-perception of their perceived competence and independence changed as a result of attending a one-week sports camp. Forty visually impaired campers ranging from 10-15 years of age, who attended a one-week sports camp, completed a survey study from two outcome measures of the American Camp Association Youth Outcomes Battery. A bivariate correlation analysis and descriptive analyses were conducted. The campers reported relatively high levels of perceived competence (5.48 ± .57) and moderate levels of perceived independence (4.94 ± …

Examining The Activity-Related Correlates Of Latine Parent Support Of Adolescents In Organized Afterschool Activities, Fuko Kiyama, Sandra Simpkins

Journal of Youth Development

Objective: This study examined the relations between Latine parent perceptions of their seventh grade adolescents’ organized afterschool activity and their support of adolescents’ participation in these organized afterschool activities; and, whether these relations varied based on the organized afterschool activity’s ethnic cultural features.

Background: Although parent support bolsters adolescents’ success in multiple contexts, including organized afterschool activities, we know little about what promotes parent support. Method: Using data on Latine parent perceptions (N = 143) of their support (17 items), of organized afterschool activities (8 items) and ethnic cultural features (7 items), linear regression models were used to evaluate the …

The challenges faced by youth can hinder them from reaching their full potential or help them grow and develop as they overcome their challenges. Grit and resilience provide young people with the skills, confidence, and perseverance to overcome challenges, pursue their goals and thrive. In this article, the authors examine the complex constructs that make up resilience and grit, draw connections to positive youth development practices, and propose a model of how these constructs can be enacted by youth development professionals in their work. The article offers specific educational practices that can support young people in developing the skills and …

Do Horse Breed Association Youth Programs Promote Life Skills And Goaldevelopment For Youth With Attention Deficit Hyperactivity Disorder?, Julius Culwell, Makenna Foster, Molly Christine Nicodemus, Molly Friend, Holly Evans, Dean Jousan, Katherine Agbigail Holtcamp, Clay Cavinder, Toree Williams

Journal of Youth Development

Almost 10% of American youth are diagnosed with attention deficit hyperactivity disorder (ADHD). While not a learning disability, this diagnosis results in youth being labeled academically “at-risk.” While equine assisted services (EAS) promote an emotionally safe learning environment for at-risk youth, program availability is limited. Horse breed associations, however, offer programs nationwide for all youth, although these programs do not have a therapeutic intention. Therefore, the objectives of this study were to utilize a survey to determine program participation and associated development of life skills and goals for ADHD youth. A survey was developed with the following: 15 fixed-response multiple-choice …

Verification Of Past Beliefs Influences Current Beliefs, Michael Wolfe, Todd Williams, Alexander J. Denison, Liam W. Hart

Open Access Publishing Support Funded Articles

Background: It is important to understand the factors that influence belief formation and belief change.

Objective: We test the hypothesis that following belief change about contentious topics, verifying a past belief will influence current beliefs.

Methods: In Experiment 1, participants reported initial beliefs about television violence in a prescreening, then read a belief-inconsistent text in the experiment. Participants either verified or did not verify their initial beliefs before reporting current beliefs. In Experiment 2, participants were randomly assigned to verify their initial belief (about gun control effectiveness), a false belief that was the opposite of their initial belief or did …

Mental Health Services In A Camp Setting: Choices, Challenges, Change, Johnathan Meier, Erinn J. Victory, Rebecca I. Laquaglia, Matthew J. Kasopsky, Jeongwi An, Gabriella R. Johnson, Andrew D. Mendonsa, Stephanie Mcwilliams

Journal of Youth Development

The prevalence of mental health issues among youth, with nearly half meeting diagnostic criteria for a mental health disorder and suicide being a leading cause of death, underscores the urgency for effective intervention (National Institute of Mental Health, 2023). Summer camps, hosting millions of children annually, are urged by the American Camp Association to establish mental health support, ranging from trained counselors to licensed therapists (ACA, 2009; 2022). At the 2023 National Scout Jamboree, mental health services were offered for the first time. During the Jamboree, 82 participants received individual or group mental health services in the Mental Health Clinic. …

Inhibitory P300 Subprocesses And Neural Compensation In Genetic Risk For Alzheimer’S Disease: The Case For Temporal–Spatial Principal Component Analysis, Elizabeth R. Paitel, Kristy A. Nielson

Psychology Faculty Research and Publications

The P300 event-related potential (ERP) is widely investigated in cognitive neuroscience, including related to aging, with smaller amplitudes and delayed latency consistently reported in Alzheimer's disease (AD). Given that AD-related neurological changes begin years before symptom onset, ERPs in asymptomatic elders with AD risk may characterize early changes. ERPs are seldom studied in this population. Yet, healthy carriers of apolipoprotein-E (APOE) ε4 have evidenced delayed P300 latencies, while P300 amplitude differences are seldom found. However, despite its frequent study, the specific cognitive processes reflected by P300 remain unclear. We propose that these challenges are due to the relatively long P300 …

Personalities Of Victims: A Look Into What Makes The Human Mind More Susceptible To Social Engineering, Matthew Ulloa

Electronic Theses, Projects, and Dissertations

Social engineering is a frequent attack used to steal information from victims. This attack has plagued businesses worldwide for many years and continues to get worse every year as it deals with the human aspect of cyber security, something often ignored in cyberspace. Humans have been deemed as the weakest link in cyber security. Previous researchers have taken it upon themselves to discover links between the human mind and social engineering. This graduate research paper was conducted on the foundation of these research papers, based on the Five Factor Model of Personalities (FFM) and susceptibility to social engineering. This research …

Intrinsic Motivation In A Virtual Reality Mock Crime Affects Participants’ Willingness To Invest More Effort In Deceptive Interviews, Isabella S. Branson, Craig P. Speelman, Shane L. Rogers

Research outputs 2022 to 2026

In studies of investigative interviewing, it is not well understood how participant experience of mock-crime activities might affect participants’ desire to perform (well) in subsequent interviews. In this study, we utilized two immersive virtual reality mock-crimes to examine if participants’ intrinsic motivation (i.e., competence, autonomy, relatedness) while committing the virtual mock-crime affects their desire to perform well in interviews. We also examined if the self-reported feeling of presence during the virtual reality mock-crime is associated with participants’ intrinsic motivation. We found significant positive associations between presence and all intrinsic motivation variables in both truth and lie conditions. We also found …

Emotional And Behavioural Difficulties Among Children And Adolescents Attending “Art Teen Clubs” In Mzuzu City In Northern Malawi: A Cross-Sectional Study, Paul U. Kaseka, Maggie Zgambo, Balwani C. Mbakaya, Mathews Lazarus, Obed Nkhata, Fatch W. Kalembo

Research outputs 2022 to 2026

Background: While triple anti-retroviral therapy (ART) has improved HIV-infected children surviving into adolescence and adulthood, these children remain vulnerable to HIV-related psychological disturbance due to both the direct HIV infection effects on the brain and indirect effects related to coping with a range of medical, psychological and social stresses associated with HIV, which makes it vital to identify their mental health needs. This study assessed the emotional and behavioural challenges of HIV perinatally infected children and adolescents with a completed disclosure process attending “ART teen club” in Malawi. Methods: A cross-sectional descriptive study design was conducted to obtain quantitative descriptive …

Investment By Maternal Grandmother Buffers Children Against The Impacts Of Adverse Early Life Experiences, Samuli Helle, Antti O. Tanskanen, David A. Coall, Gretchen Perry, Martin Daly, Mirkka Danielsbacka

Research outputs 2022 to 2026

Exogenous shocks during sensitive periods of development can have long-lasting effects on adult phenotypes including behavior, survival and reproduction. Cooperative breeding, such as grandparental care in humans and some other mammal species, is believed to have evolved partly in order to cope with challenging environments. Nevertheless, studies addressing whether grandparental investment can buffer the development of grandchildren from multiple adversities early in life are few and have provided mixed results, perhaps owing to difficulties drawing causal inferences from non-experimental data. Using population-based data of English and Welsh adolescents (sample size ranging from 817 to 1197), we examined whether grandparental investment …

Experimental Evidence That Activewear Retail Imagery Elicits Physiological, Attentional And Self-Reported Markers Of Body Image Threat In Women, Ross C. Hollett, Muna Bhusal, Syed Zulqarnain Gilani, Craig Harms, Scott Griffiths

Research outputs 2022 to 2026

Online apparel retail imagery is a prominent threat to women's body image, particularly segments such as activewear which emphasize the value of women's bodies. In a within-subjects experiment, we exposed women (N = 128) to imagery randomly selected from activewear, casualwear and homewares websites and measured their gaze behavior, physiological arousal, as well as subjective emotional states and body image ratings. Exposure to activewear retail imagery elicited significantly lower body image ratings, a higher negative emotional state, and a lower positive emotional state compared to the other website imagery conditions. Physiological arousal was significantly higher for both apparel imagery conditions …

Influence Of Officers’ Race, Suspects’ Characteristics, And Arrest Contexts On Police Homicide Victim Risk Factors, Dominique Damon Block

Walden Dissertations and Doctoral Studies

Media attention on the fatal use of force by law enforcement personnel has worsened the divide amongst the police and minority communities, intensifying the lack of confidence between groups. Further research is called for to understand how the fatal use of force by law enforcement is influenced by officer race, suspect race, and characteristics of the alleged crime. Implicit bias theory and procedural justice theory were used as theoretical and conceptual frameworks. The three research questions examined the extent to which characteristics of the officer, characteristics of the alleged perpetrator, and circumstances of the homicide predicted (a) perpetrator mental illness, …
