From Review To Synthesis: A Step-By-Step Methodological Guide To Systematic Reviews And Multilevel Meta-Analyses, Meilan Hu, Paye Shin Koh, Xun Ci Soh, Andree Hartanto, Nadyanna M. Majeed

Research Collection School of Social Sciences

We provide a step-by-step guide on conducting a quantitative systematic review (i.e., meta-analysis) using the open-source programming language R, as well as conducting a multilevel meta-analysis, in contexts where effect sizes are non-independent (e.g., multiple studies from the same lab). Quantitative systematic reviews offer researchers a method for synthesizing large bodies of literature, helping clarify inconsistent findings, identify research gaps, and refine theoretical models. However, existing tutorials often assume prior knowledge and/or experience, often overlooking foundational concepts. To address this gap, a comprehensive walkthrough of the systematic review process is presented, covering pre-registration, literature search and retrieval, screening, risk of …

Daily Problematic Smartphone Use Predicts Decreases In Self-Control Capacity: Evidence From Random-Intercept Cross-Lagged Panel Model, Adalia Yin Hui Goh, Andree Hartanto

Research Collection School of Social Sciences

Amidst the widespread increase in global smartphone screen time and the phenomenon of ‘The Great Exhaustion’, where multiple surveys indicate pervasive tiredness and feelings of being drained, there is growing concern about the link between problematic smartphone use and the capacity for self-control. While numerous studies have investigated the relationship between problematic smartphone use and self-control capacity, they are mostly cross-sectional. Thus, it is unclear whether the lack of capacity for self-control is an antecedent or consequence of problematic smartphone use. Addressing the research gap, we conducted a 7-day diary study to investigate the bidirectional relationship between problematic smartphone use …

Unlocking The Power Of Cultural Humility In Political Institutions As Workplaces: Authentic Leadership As A Pathway To Psychological Well-Being Among U.S. State Legislators, Kristine M. Reeves

Industrial-Organizational Psychology Dissertations

Political institutions, particularly U.S. state legislatures, function not only as sites of governance but also as complex workplaces characterized by high public scrutiny, identity salience, and multidirectional power dynamics. Despite these conditions, limited research has examined how leadership processes influence the psychological well-being of those who serve within them. This research draws on humility theory, authentic leadership theory, social identity theory, and positive organizational behavior to examine the role of cultural humility in fostering authentic leadership and psychological capital (PsyCap) among U.S. state legislators. Using a cross-sectional survey design, data was collected from 160 U.S. state legislators. Cultural humility was …

All-Inclusive List of Electronic Theses and Dissertations

This study set out to explore what can be done to improve outcomes for students in Indiana public schools and beyond by exploring ways in which educational leaders might be able to increase levels of teacher self-efficacy in their existing staff. It looked specifically at intellectual play, defined as the behaviors associated with metacognition, play, and innovation, and analyzed its relationship with teacher self-efficacy. Student achievement and overall success in school is critically important to them as individuals and to our society as a whole. If there are innovative ways to improve those outcomes for students, they should be explored. …

Well-Being Of University Students In Singapore, Tina Li Yi Ng, Andree Hartanto, William Tov

Research Collection School of Social Sciences

Singapore provides an insightful case study for university student well-being due to its national culture of competitiveness. Amid a meritocratic society that valorizes academic success as the path to securing one’s future (Ho et al., 1998), educational attainment is central to Singaporean university students’ well-being (Inter-University Network, 2022). In response to Singapore’s increasing incidence of mental health challenges among young adults (Ministry of Health Singapore, 2022), the government and higher education institutes have sought to destigmatize mental health and improve accessibility to related resources. In this chapter, we review the literature on the well-being of Singaporean university students. We situate …

The Emerging Roles Of Ai In Self-Directed Stress Management: Systematic Review, Mary Kamillah Grace Reyes, Shauna Sha Min Teo, Andree Hartanto

Research Collection School of Social Sciences

Background: Stress is widespread and carries substantial mental health, social, and economic burdens. Yet, access to clinician-led stress management remains constrained by service capacity, cost, and stigma. In response, artificial intelligence (AI)–enabled tools have rapidly proliferated as scalable, self-directed options. However, evidence on how these systems support stress management outside formal clinical settings remains fragmented. Objective: This systematic review aimed to synthesize empirical evidence on how AI-enabled technologies are used for self-directed stress management. We mapped the emerging functions of these tools, the psychological frameworks informing their design, the populations and settings studied, and the outcomes reported. Methods: We conducted …

Ai Fatigue In Human–Ai Interaction: Conceptual Framework, Scale Development And Validation, And Associations With Ai Engagement, Gabriel R. Lau, K. T. A. Sandeeshwara Kasturiratna, Adalia Y. H. Goh, Eddie M. W. Tong, Andree Hartanto

Research Collection School of Social Sciences

Emerging from the accelerating pace of AI development, user fatigue arising from prolonged human–AI interaction has become an increasing concern in public discourse. This growing attention underscores the need to clarify why sustained engagement with AI systems can generate psychophysiological strain and how such exhaustion manifests in users. The present research develops a conceptual framework for AI fatigue and introduces the 15-item AI Fatigue Scale as a validated tool for examining its correlates. Across four studies with 717 participants, we generated and content-validated an item pool, identified and confirmed a four-factor (cognitive, emotional, physical, behavioural) higher-order model. The scale demonstrated …

Durable Benefits Of Learning-By-Teaching For Research Question Generation Performance: A Field Experiment, Stephen Wee Hun Lim, Sarah Shi Hui Wong, Piyawan Visessuvanapoom

Research Collection School of Social Sciences

Generating good questions is central to scientific inquiry. How can we improve this skill in classrooms? This field experiment showed that teaching others enhances students’ ability to generate higher-order research questions that create new knowledge. Whereas learning-by-teaching often involves delivering face-to-face or video-recorded lectures, we tested its efficient implementation via writing a verbatim (i.e., word-for-word) teaching script, exactly as how one would orate a lecture. In a research and statistical methods course, 199 undergraduates studied statistical concepts by writing verbatim teaching scripts or study notes. One month later, students’ long-term learning was assessed on a high-stakes test, whereby they explained …

Understanding Adolescents’ Attitudes Toward Disabilitiesto Improve Out-Of-School Programs, Vanessa Spero, David C. Diehl, John M. Diaz, Serap Gorucu

Journal of Youth Development

This study explores adolescents’ attitudes and perceptions toward individuals with disabilities in out-of-school time (OST) settings. Gaining insight into these attitudes can help inform future initiatives and interventions to develop programs that foster inclusion and greater participation of people with disabilities in OST programs. This study employed quantitative methods using the Brief Questionnaire for Adolescents on Attitudes Toward Persons with a Disability (CBAD-12A), developed by Álvarez-Delgado et al. (2020), to survey adolescents about their attitudes and perceptions toward individuals with disabilities. The results of the study revealed no statistically significant differences in attitudes toward individuals with disabilities based on whether …

The Heart Of Camp: Belonging, Relationships, And Growth Of Character And Skills, Alecia Moser, Nila Rosen, Maurice Elias, Sarah R. Sprayberry, Andrea Vest Ettekal

Journal of Youth Development

This study examined how campers’ experiences of belonging, counselor support, and new close friendships relate to life skill and character development in North American Jewish youth. Residential summer camps are relational settings that promote positive youth development. Although belonging and supportive relationships are theorized to drive such development, few studies have tested these camp features in current camper populations, and less is known about how friendship formation and perceptions of counselors distinctly interact with belonging to shape development. In this study, end-of-summer surveys were administered to middle- and high-school-aged campers at five Jewish residential summer camps. Measures included assessing belonging, …

4‑H Efforts Toward Demographic Representation, 1980–2025: A State‑Of‑The‑Art Review (Part 1), Jeremy Elliott-Engel, Jeff Wayne Howard

Journal of Youth Development

This state-of-the-art review synthesizes 45 years of scholarship (1980–2025) to assess how effectively the 4-H program has worked to serve a demographically representative youth population. Drawing on academic and gray literature (n=99) sources, the review traces 4-H’s evolution from its segregated land grant origins to contemporary efforts focused on access, equity, inclusion, and belonging. It documents progress in culturally responsive programming and national diversity, equity, inclusion (DEI) initiatives while highlighting persistent disparities in participation and benefit distribution. The review identifies effective strategies, enduring structural barriers, and areas where research and practice remain limited, offering a comprehensive foundation for understanding 4-H’s …

Psychological Science Faculty Research & Creative Works

Introduction We conducted a prospective imaging clinical trial to evaluate rapid cone-beam computed tomography (CBCT) imaging on a C-arm linear accelerator. As part of this trial, we evaluated patient-reported anxiety and distress before and after imaging sessions to evaluate the impact of increased gantry rotation speed on patient experience. Materials and methods Forty patients undergoing radiotherapy (RT) as part of standard clinical care were separately imaged using CBCT imaging on a C-arm linear accelerator with faster gantry rotation (1.5 rpm versus standard 1.0 rpm speed used clinically) as part of an imaging clinical trial. Patient anxiety and distress were evaluated …

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …

The Impact Of Religious Behaviors, Islamophobia, Gender Roles, Language Proficiency, And Education Levels On Mental Illness Stigma And Help-Seeking Behaviors Among Arab Women In The U.S., Rima Muhsen

Dissertations

The official U.S. census does not provide data on the number of Arab Americans in the United States, which hinders studies that focus on this population group to explore their needs and improve access to mental health services. Arab women in America represent a subgroup that has received insufficient attention from researchers, particularly regarding culturally sensitive topics such as mental health problems and their associated stigma. The influence of cultural, social, and religious factors on self-stigma associated with mental illness has not been adequately studied among this marginalized group. While previous research has suggested a relationship between self-stigma, social stigma …

Well-Being, Resilience, And Trauma During Migration: A Mixed Methods Study Of Venezuelan Migrants In Transit, Margaret S. Port

Dissertations

A substantial body of research has examined the psychological impact of experiences preceding and following migration, yet comparatively little attention has been given to the psychological toll of the migration journey itself. Moreover, due to the relative novelty of the Venezuelan migrant crisis and the community’s arrival in the United States, the psychological impact of Venezuelan migrants’ unique migration experience has been underexamined. This study utilized an explanatory sequential mixed methods design to investigate the relationships between well-being, resilience, and trauma among Venezuelan migrants in Chicago, Illinois, while also exploring their lived experiences of the migration journey. Study participants (n …

Specifically, the review explores the mental health concerns experienced by athletes engaged in high-level sport. It examines whether cognitive behavioral therapy and mindfulness-based interventions are effective approaches for improving psychological outcomes in this population. A systematic review of peer-reviewed research was conducted, and findings were synthesized to evaluate the effectiveness of cognitive behavioral therapy and mindfulness-based interventions. The review included randomized controlled trials, quasi-experimental studies, and meta-analyses examining psychological interventions in athletic populations. Findings across the literature indicate that both cognitive behavioral …

Diverse Families Navigating Mental Health At The Pediatrician’S Office: A Mixed Methods Exploration Of The Interplay Of Stress, Culture, And Child Mental Health In The Primary Care Setting, Sara B. Budowsky

Dissertations

Low-income and ethnic minority youth experience high psychiatric need but persistently low participation in traditional mental health care. General pediatricians are often the first and only healthcare providers with whom many families engage around their child’s emotional and behavioral development. Using both quantitative analysis of retrospective secondary data and Interpretative Phenomenological Analysis (IPA) of in-depth interviews with diverse caregivers, this project explored influencers of child mental health and family utilization of pediatric primary-care-based mental health services in the context of a uniquely multicultural clinic serving a predominantly Medicaid population. Three key findings include: 1) Caregiver Stress was a highly significant, …

Exercise Therapy For Mood Disorders In Retiring/Former Athletes, Christian Antos

Dissertations

This dissertation examined the potential integration of exercise therapy and psychotherapy as a treatment approach for mood-related difficulties experienced by former elite athletes during the transition out of competitive sport. Retirement from athletics is often associated with significant biopsychosocial challenges, including disruptions in identity, healthy routines, social support, and emotional well-being. Existing literature suggests that exercise may serve as an effective adjunctive intervention for improving mood and overall psychological functioning, though limited research has explored its application among retiring athletes within psychotherapeutic contexts. This literature review synthesized current research related to athletic retirement, neurobiological mechanisms associated with physical activity, and …

The Effects Of Virtual Feedback Delivery Methods On Performance For A Remote Work Task, Megan J. Ireland

Masters Theses

Due to its multifunctional nature and wide array of possible applications, feedback has been, and continues to be, a popular topic within scientific research focused on workplace performance improvement. To ensure that feedback is implemented correctly for the desired behavior change, and the context in which it is being delivered, the variables that make up feedback have been a primary focus of more recent research. Previous research has investigated a variety of variables including the effects of delivering different types of feedback and the effects of different feedback delivery modalities on performance for work-related tasks. The present study will be …

An Inferential Analysis Of Lexical Networks, Christopher D. Gravelle

Dissertations, Theses, and Capstone Projects

Lexical networks are graphs where words are treated as nodes, and relations between words are treated as edges. The adoption of lexical networks in psycholinguistics is impeded by a lack of readily available inferential methods, which limits work to purely descriptive analyses with little ability to make inferences about what variables account for lexical network structure. The current research explores the use of latent space network models as a method for analyzing lexical networks. Latent space network models are latent variable regression models, which model the presence or strength of edges by estimating pairwise distances between nodes in a latent …

A Simulation To Compare Models For A Longitudinal Ordinal Response With A Multilevel Cross-Classified Data Structure, Rachel S. Perlin

Dissertations, Theses, and Capstone Projects

This is a simulation study that compares four models for analyzing three-level longitudinal cross-classified data with an ordinal outcome, treatment effect and a category-specific effect. The models include the cumulative model, the sequential model, the adjacent category model, and a metric model. Data were generated for each of the first three models with 27,000 generated datasets each, totaling 81,000. The datasets vary along three continuous variables: the number of level-3 units, the ratio of treatment groups to control groups, and the treatment effect size. The outcome has four ordinal response categories. Each model had two predictor variables: treatment and time. …

Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad

Dissertations, Theses, and Capstone Projects

Breast cancer survivors (BCS) often report noticeable cognitive difficulties despite showing limited impairment on standardized neuropsychological tests. Some have theorized that this is simply an insensitivity of standardized testing to subtle cognitive changes (test-insensitivity hypothesis), whereas others have suggested there are early neural changes that are detected by patients but precede detection by these tests (early signal hypothesis) or that when they achieve normal performance, it is through saliently effortful compensatory processes (compensation hypothesis). The present study tested these theories by assessing metamemory and recognition memory retrieval in BCS and non-cancer controls (NCC) using both behavioral and event-related potential (ERP) …

Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames

Dissertations, Theses, and Capstone Projects

Hearing aid stigma remains a significant barrier to treatment uptake, with device visibility frequently identified as a contributing factor. Although prior research has examined visibility in relation to hearing aid size and style, the role of color as a distinct aesthetic dimension has not been systematically investigated. The present study assessed whether hearing aid color affects implicit and explicit attitudes toward hearing aids and whether such evaluations differ across contexts. Twenty-six adults who were not current hearing aid users participated in an online quantitative multi-method study consisting of an Implicit Association Test (IAT) and self-report questionnaires. The IAT measured implicit …

Reducing The Complexity Of The Experimental Design Attenuates Trait-Level Effects In Threat Safety Discrimination Learning, Justin M. Lazzarino

Dissertations, Theses, and Capstone Projects

Trait measures of negative emotionality have sometimes been shown to play a role in shaping threat learning, but findings are mixed. For example, Johnson et al (2023) showed that the inhibitory and prospective subscales of the Intolerance for Uncertainty Scale (IUS) were associated with diminished and enhanced threat-safety discrimination, respectively, during the acquisition phase of a Pavlovian fear conditioning task. This finding was subsequently replicated in an independent sample (Kinney-Petrucha, 2024, unpublished). However, these findings and other trait-level fear acquisition effects have not been consistently observed in the broader fear learning literature. Variation in the complexity of or uncertainty inherent …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

An Ecological Approach To School Climate, Safety, And Space: Accounts From Educators, Architects, And Guidelines, Mahnaz Izadi

Dissertations, Theses, and Capstone Projects

This dissertation explores how the spatial and social contexts of schools interact to influence how school safety and climate are perceived and enacted. Using ecological psychology theories, I examined the perspectives of teachers, counselors, and architects, school stakeholders involved in school planning and operation at different times, with varying levels of control and involvement in the daily life of schools. The study investigates how these stakeholders think about school climate and safety, the strategies they employ to improve it, and the challenges they face in doing so.

This qualitative study employs semi-structured interviews with 11 teachers and 4 counselors from …

Exploring Minor Feelings: Asian And Asian American’S Racialized Emotions, Identity, And Mental Health Amidst Covid-19, Kristina Mirasol Arevalo

Dissertations, Theses, and Capstone Projects

The COVID-19 pandemic highlighted the central role of racialized emotions in shaping how Asians/Asian Americans (A/AA) experience, interpret, and respond to racism, yet these emotional processes remain underexamined in psychological research. Rather than treating emotions as outcomes of discrimination, this dissertation conceptualizes racialized emotions as dynamic processes through which structural racism is experienced, interpreted, and embodied in everyday life. This framework positions racialized emotions as a key mechanism linking racialized social contexts to identity development and mental health. Across three studies using qualitative and quantitative methods, I examine how racialized emotions shape racial meaning-making, ethnic-racial identity, and psychological well-being among …

Temporal Integration In Music And Aesthetic Judgments: Assessing Musical Taste Through A Transformer-Based Approach, Sophia M. Senderak

Dissertations, Theses, and Capstone Projects

Music unfolds over time, requiring listeners to integrate information moment by moment to make aesthetic judgments. Although we know that music is likely processed on multiple timescales, it is not known which musical features contribute to short versus long timeframes. This study examined whether a computational measure of temporal integration could help explain aesthetic responses to music. Participants (N = 28) listened to 32 sixty-second clips of classical and electronic music, and continuously rated their enjoyment with a dial. After listening, they then gave an overall liking judgment for each clip. To quantify temporal integration, we derived an integration measure …

Healing Historical-Intergenerational Trauma And Colonial Soul Wounds With Ancestral Healing Practices And Psychosocial Limpias: An Ofrenda For The Salvadoran Community, Joanna D. Beltrán Girón

Dissertations, Theses, and Capstone Projects

In 1992, the United States-backed Salvadoran military and the leftist guerrillas signed the Chapultepec Peace Accords, which put an end to a 12-year war in El Salvador that resulted in 75,000 deaths, 12,000 forced disappearances, and half a million internal displacements. Around 85% of the reports made by survivors of the war attributed the violence to state agents, paramilitary groups, and death squads.While taking into account this history of state violence, this dissertation is interested in the psychosocial aftermath of the war and in how survivors integrate healing practices in their lives in response to the painful memories their bodies …
