Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore

Theses and Dissertations--Psychology

Rhythms are central to nearly every core physiological and psychological process and have profound influences on overall health and well-being, particularly in the context of mood disorders. This dissertation emphasizes a rhythm-centered framework for understanding transdiagnostic psychopathology, proposing that the temporal organization of psychosocial stress, sleep, and mood provides crucial information for the development and treatment of mood disorder symptomology. Current literature relies primarily on mean symptom levels, overlooking day-to-day patterns in psychosocial experiences. To address this key methodological gap, three studies are examined. Study 1 develops and validates the Psychosocial Stress Regularity Measure (PSRM), a brief single-item measure of …

Robust Linking Estimation In Item Response Theory Using Quantile Regression: Applications To The Graded Response And Generalized Partial Credit Models, Ibrahim Almansour

Graduate Studies Theses and Dissertations 2026

This dissertation investigates robust estimation of linking coefficients in Item Response Theory (IRT) using quantile regression and its extensions. Linking procedures are essential for placing item and ability parameters from different test forms onto a common scale, thereby ensuring comparability of examinee scores across administrations. Traditional approaches such as moment methods, characteristic curve methods, and mean-based regression procedures like Ordinary Least Squares (OLS) and Generalized Least Squares (GLS) perform adequately under ideal conditions but tend to lose accuracy when ability distributions deviate from normality or include outliers.

To address these limitations, this research proposes a quantile-based regression framework that estimates …

Behavioral Economic Factors Implicated In Young Adult Drinking In The Natural Environment: An Ema Study, Tatiana Magri

Graduate Studies Theses and Dissertations 2026

Background: Young adult (YA) alcohol use remains a prominent public health concern. Despite research efforts aimed at mitigating harms related to drinking, rates of alcohol use and adverse outcomes related to use, remain high among YAs. Previous research has identified alcohol demand, craving, and delay discounting as risk factors for problematic drinking among YAs. However, few studies have concurrently examined these constructs using methodologies that maximize ecological and contextual validity. Method: YA individuals (N=104) completed an ecological momentary assessment (EMA) protocol assessing three demand indices (i.e., intensity, Omax, and breakpoint), delay discounting, craving, and alcohol use and problems. Participants received …

I Think, Therefore I Can: Self-Efficacy, Self-Regulation, And Sense Of Belonging In Introductory Physics, Danielle Christine Maldonado

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cognitive and affective beliefs in physics classrooms are important indicators of student success beyond traditional measurements of academic performance. This body of work explores major beliefs and processes, including self-efficacy, self-regulation, and sense of belonging, as they relate to academic achievement among introductory undergraduate physics students. First, this dissertation explores the development of physics self-efficacy and physics sense of belonging, two highly correlated variables. This work identifies unique sources of physics self-efficacy and sense of belonging development from current and prior academic experiences, personality factors, and demographic variables. Then, relationships between early- semester self-efficacy and sense of belonging, mid-semester …

Tl;Dr (Too Long; Didn't Read): Examining The Assessment And Causes Of Careless Responding Within Experimental Vignette Studies, David L. Sexton Jr.

Graduate Studies Theses and Dissertations 2026

Careless responding occurs when participants answer survey items without considering their content and poses a serious threat to data quality. However, while past research has examined its deleterious effects on both survey and low-stakes cognitive ability measures, little research has focused on careless responding in experimental vignette methodology (EVM) research. EVM studies require participants to attend to one or more experimental vignettes, which are carefully crafted written scenarios designed to manipulate a focal variable across conditions. However, if participants are careless in attending to study vignettes, they may not be exposed to the researchers’ intended experimental manipulations, thereby precluding them …

Resources And Coping Strategies In Adverse Work Situations: A Person-Centered Approach, Chad Yagey

Graduate Studies Theses and Dissertations 2026

The resilience process model highlights an approach to how people mobilize their resources to cope and positively adapt in the face of adversity. Leveraging Conservation of Resources (COR) theory and the Work Home Resources Model (WHRM), I aim to uncover the extent to which resilience capacity (resources) and resilience enactment (coping) influence outcomes of resilience, offering one of the first empirical tests of the resilience process model. Specifically, COR theory posits that the more psychological resources someone has, the more successful they are in coping. I challenge this notion by examining whether specific profiles of the combination of resources available …

Examination Of The Effects Aesthetic Enrichment And Music Have On Well-Being And Task Performance In A Workplace Simulation, Emily Budik

Theses and Dissertations

Workplace environments are often designed with a focus on efficiency, yet emerging research suggests that environmental features such as aesthetic enrichment and music may influence employee well-being and performance. The present study examined whether visual aesthetic enrichment and auditory stimulation through music could improve well-being, reduce stress, and enhance task performance within a simulated workplace task. Participants completed a 30-minute in-basket task under one of four conditions: a control environment, music only, aesthetic enrichment only, or a combined aesthetic enrichment and music condition. Measures of stress, well-being, and task performance were collected following task completion. Results indicated that neither aesthetic …

It is hypothesized that women who have experienced intimate partner violence within a religious context will score …

Exploring The Impact Of Inpatient Mental Health Care On Adolescents, Alexandria M. Mckahan

2025 Fall Honors Capstones Projects - Archive

Adolescent psychiatric hospitalizations continue to rise, yet there is limited research on which daily practices inside inpatient units genuinely support engagement and recovery. This project examined how structure, staff tone, and therapeutic programming influence adolescents’ participation and emotional stability within a real inpatient setting. The study focused on three questions: how structured routines affect recovery, what challenges staff face when supporting adolescents with complex needs, and how adolescents’ engagement patterns reflect their perception of care. Using a mixed-methods case study at Mesa Springs Behavioral Health Hospital, I conducted approximately twenty field observations, semi-structured staff interviews, and descriptive engagement tracking across …

Treatments Of Ordinal Scales In Latent Profile Analyses: A Comparison With Monte Carlo Simulations, Chongming Yang, Joseph Olsen, Caleb Carlyle

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

Person-centered approaches to analysis/modeling provide certain advantages and methodological possibilities. Ordinal psychological scales have been used differently in latent profile analysis (LPA), including sums, means, standardized scores, and factor/latent scores, meanwhile it was uncertain to what extent these treatments would yield equivalent class proportions and univariate differences. This study simulated LPA of different treatments of ordinal scales (unweighted and weighted means, sums, standardized sums, and latent factor scores) with different response options (2, 3, 5, and 7) at different sample sizes (N = 240/300 or 600) under maximum likelihood (ML) and Bayesian estimations. Compared to other treatments of ordinal …

From P-Values To Practical Relevance: An Introduction To Effect Sizes Through A Legal Psychological Example, Paul Riesthuis, Henry Otgaar, Tery Setiawan, Nathanael Sumampouw, Charlotte Bücken

Psychological Research on Urban Society

Null-hypothesis significance testing and p-values are frequently criticized for their focus on detecting non-zero differences and their inability to provide evidence for the null hypothesis. In this article, we highlight how effect sizes, when meaningfully interpreted, can address these issues. Specifically, we argue that researchers should consider the smallest effect size of interest (SESOI) - the smallest effect size that yields practical or theoretical relevance. We propose several methods for estimating the SESOI and present a consensus study among Indonesian professionals which can be used to estimate the SESOI for child eyewitness testimony research. Results suggest that most Indonesian professionals …

Association Between Decisional Conflict And Quality Of Life Among Parents With A Child Undergoing Hospital-Based Treatment For A Recent Cancer Diagnosis, Augustine Provencio

Doctoral Dissertations

Having a child with a chronic illness, such as cancer, can cause families significant distress. Parents of these children must make frequent decisions relating to their child’s care. Depending on factors such as health literacy and support from medical staff, parents may have varying levels of decisional conflict (DC) throughout the decision-making process. Compounding stress throughout their child’s illness can often contribute to lower levels of health-related quality of life (HRQoL) while their child is receiving hospital-based treatment. Parents with a non-English language preference (NELP) often have greater challenges navigating healthcare systems due to a lack of resources and limited …

Supervisee Barriers To Disclosure And The Supervisory Working Alliance, Rachel G. Hughitt

Electronic Theses and Dissertations

This study investigated barriers influencing supervisees’ willingness to disclose clinical errors in mental health training contexts, with a focus on the supervisory working alliance (SWA) as a potential moderating factor. Participants read two vignettes – one describing a clinical error and the other a client concern – and were asked to indicate which case they would discuss with their supervisor. They also completed the Brief Supervisory Working Alliance Inventory–Trainee Form (BSWAI-T) and the Supervisee Disclosure in Supervision Scale (SDSS), which assessed the quality of the supervisory alliance and perceived barriers to disclosure, including fear of negative evaluation, lack of confidence, …

Re-Engaging Driver Attention Using Chatgpt: A Multimodal Study On Stress Impact And Driving Performance, Alaa Zaki Elfiqi

Theses and Dissertations

Driving is considered a complex task that requires continuous focus and attention from the driver. Driving performance can also be impacted by changes in the driver’s stress level. However, limited research explores methods to address this challenge. With the current advances in Large Language Models (LLMs) and their ability to engage in human-like interaction, this study investigates the potential of using ChatGPT, designed to speak Egyptian Arabic, in re-engaging driver attention under different driving scenarios for low-stress and high-stress conditions within a virtual reality (VR) environment driving simulator. Drivers were asked to follow a leading car into two scenarios with …

Polymathy: The Foundational Source Of Creativity And Innovation., Michael Araki

Electronic Theses and Dissertations

In an era of mounting complexity and a growing need to transcend siloed thinking, this dissertation advances polymathy as a critical yet underexplored construct in the management and behavioral sciences. Polymathy is framed as an expansive approach to the pursuit, development, and application of knowledge, marked by the conjunction of breadth, depth, and integration. Building on a thought lineage that stretches from Ancient Greece through the Renaissance to the present day, this work shows that polymathy is neither a relic of the past nor an achievement reserved for a few—but a mode of being, thinking, and acting in the world …

Makara Human Behavior Studies in Asia

This study aimed to translate, adapt, and validate the modified version of the Player Experience of Need Satisfaction (PENS) for Malaysian Multiplayer Online Battle Arena (MOBA) players. The translation and adaptation process involved a rigorous procedure with nine mental health and linguistic experts. A non-probability sampling method was applied by recruiting 491 participants from the MOBA Facebook groups. The parallel analysis indicated a two-factor structure (autonomy and competence as one factor and relatedness as another factor). Confirmatory factor analysis demonstrated a better model fit for the translated version compared with the original English version, with satisfactory psychometric properties. Future studies …
