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 …

Investigating The Relationship Between Noun Classes And Plant Folk Taxonomy In Chasu Language Of Kilimanjaro Region In Tanzania, Peter Rabson Mziray

Journal of Humanities and Social Sciences

The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

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 …

Body Acceptance, Body Dysmorphia Symptoms, And Selfie Behavior: Unpacking Their Relationships Among Filipinos, Marc Eric S. Reyes, Alyssa Ashley O. Ang Tong, Sherry Lyn H. Cada, Raymond Nathan A. Lopez, Jv Louise D. Natividad

Makara Human Behavior Studies in Asia

The emergence and proliferation of social media gave rise to “selfitis,” an obsession-compulsive engagement in photo selfie-related activities. This phenomenon raises a problem, especially for people experiencing body acceptance concerns and body dysmorphia symptoms, as both of these variables may be linked with photo selfie-taking behavior. With the Philippines having the second-highest average daily social media usage globally, this study explored the association between body acceptance, body dysmorphia symptoms, and selfie behavior. We utilized a cross-sectional explanatory design and investigated the possible mediating and moderating role of body dysmorphia symptoms in the relationship between body acceptance and selfies among 506 …

Translation, Adaptation, And Validation Of Player Experience Of Need Satisfaction Scale (Pens) Modified Version In Malaysian Multiplayer Online Battle Arena (Moba) Players, Soo Ting T'Ng Dr, Khee Hoong Ho, Wen Sam Leong, Poh Chua Siah, Nurul Iman Binti Abdul Jalil, Kee Pau

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 …

Straddling The Boundary Of Misleading Information Group: Exploring The Association Between Network Brokerage And Morality Expressions, Yiqi Li, Marina Mitiaeva, Ximeng Deng, Una Joh, Yafei Zhang

iSchool - All Scholarship

Existing misleading information studies mostly focus on either the message content or social network structures, overlooking the association between the content and structural factors. This research examines the role of brokers, the key network actors straddling between misleading and true/regular information groups. Content-wise, morality expressions are examined, which signal social media users’ expressions toward what is right and wrong. This research provides insights into the understudied relationship between network brokerage and moral expressions and identifies connections between moral foundation and network brokerage theories. Findings suggest that binding morality (i.e., authority and loyalty) is dominant among network brokers. Practical strategies are …

Investigating The Impact Of Cross-Loadings On Model Fit And Mediation Inferences In The Latent Mediator Model, Qiulin Lu

Theses and Dissertations

Cross-loadings are a common phenomenon in psychological research. Extant studies have focused primarily on measurement models, like confirmatory factor analysis (CFA), and have shown that omitted cross-loadings can bias the inter-factor correlation. These results suggest that omitted cross-loadings might likewise bias structural paths in other structural equation models (SEMs), but this area remains under-investigated. Such an effect could impact the evaluation of third variable effects, like mediation, when estimated in a SEM framework.

This study addresses this gap by examining the effects of cross-loadings in single, latent mediator model in a simulation study. The performances of conventional SEM and Bayesian …

Natural Language Processing Pipeline For Assessment Data: An R-Based Tutorial, Constanza Mardones-Segovia, Shiyu Wang, Allan S. Cohen

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

Natural language processing (NLP) has become an increasingly popular approach for analyzing textual responses in educational assessments. An important part of NLP involves cleaning and structuring examinees' written responses to create input data that conserves the syntax, semantics, and pragmatics of the words, thereby enabling the extraction of these features. This paper provides foundational knowledge on the steps needed for using NLP in educational measurement tasks, guiding researchers and practitioners through text preprocessing, feature extraction, and analyzing textual data from constructed response items. Additionally, an R-based example using Latent Dirichlet Allocation is provided, illustrating each step in the pipeline.

Minority Stressors And Internalizing Symptoms In Sexual And Gender Minority Adolescents: A Systematic Review And Meta-Analysis, Anni R. Subar

Electronic Theses and Dissertations

Sexual and gender minority (SGM) adolescents are at elevated risk for internalizing symptoms, such as anxiety and depression, due in part to chronic exposure to minority stress. To provide a comprehensive synthesis of this literature, we conducted a meta-analysis of 32 studies, yielding 162 effect sizes from 41,360 participants aged 8– 22. All included studies examined the association between minority stress, defined as stigma-related stressors such as discrimination, victimization, and internalized stigma, and internalizing outcomes in SGM youth. The random-effects meta-analysis revealed a small but significant association (r = .25) between minority stress and internalizing symptoms, consistent across stressor …

Young Adults’ Metaperceptions Of Their Childhood Caregivers’ Appraisals And Young Adulthood Mental Health, Cassandra Svelnys

Electronic Theses and Dissertations

Early experiences and relationships have enduring impacts on the development of self and later mental health and wellbeing. In social relationships and interactions, the developing individual is continuously assessing how they view themself, how they view the other person, and how they believe the other person views them. Metaperceptions represent the latter construct: how an individual thinks another person perceives them. Childhood self-esteem, parent-child attachment, and metaperceptions are foundational constructs for the developing individual, yet metaperceptions have not previously been tested as a predictor for adulthood mental health while also accounting for childhood self-esteem and parent-child attachment. This study introduced …

Schwartz Values Of Active-Duty U.S. Soldiers: A Confirmatory Factor Analysis Of Refined Values, Kelcey Sihanourath

Walden Dissertations and Doctoral Studies

The U.S. Army is currently facing recruitment challenges due to a decrease in the number of qualified youths. When recruitment is low, reducing attrition becomes even more critical to maintaining force readiness. Research indicates attrition patterns may be influenced by interactions between personal characteristics and the unique culture of each military branch. One characteristic is personal values; however, the most widely used personal values framework, Schwartz’s values theory, has not been validated for the U.S. Army population. This study aimed to address this gap by empirically assessing Schwartz’s values using a nonexperimental cross-sectional quantitative design, collecting data from 273 active-duty …
