Online Act Guide For Sub-Clinical And Clinical Insomnia Among College Students, Guadalupe "Gabe" San Miguel

All Graduate Theses and Dissertations, Fall 2023 to Present

College students are shown to have more sleep difficulties, specifically insomnia. These sleep difficulties compared to the general public due to the college environment (for example increase screen time, sedentary time, or alcohol use). Students with reported sleep difficulties have ties to lower GPA and lower odds of graduation. That is why this dissertation conducted a comparison between an online version of Acceptance and Commitment Therapy (intervention) to a placebo condition among college students with insomnia to help determine if the intervention had better outcomes over time. Each condition (intervention = 39; placebo = 40) completed questionnaires at the start …

The Effect Of A 14-Day Digital Nudge-Based Sleep Hygiene Intervention On Behavioural, Cognitive, And Emotional Well-Being In College Students: An Experimental Approach, Tracy X. Chen, Chi-Ying Cheng, Michelle Koay, Chin Boon Soh, Andree Hartanto

Research Collection School of Social Sciences

Sleep is essential for one's cognitive, psychological, and physical health. Yet, college students often face sleep deprivation due to academic demands, social obligations, and extracurricular commitments. This study implemented a 14-day Digital Nudge-Based Sleep Hygiene Intervention, delivered via a digital platform, to encourage healthier sleep practices among college students. Grounded in nudge theory, the digital intervention used subtle behavioural prompts to improve participants' sleep hygiene without imposing restrictions, demonstrating high adherence and scalability. Participants were guided through daily tasks to enhance autonomy and motivation, such as creating calming bedtime routines. The digital intervention led to positive outcomes across four domains: …

Expanding Links Between Work Values And Occupations: Development Of The Occupational Values Inventory (Ovi), Nicholas F. Heimpel, Kevin Hoff, Zihan Liu, Federick L. Oswald, James Rounds

Research Collection Lee Kong Chian School Of Business

This research developed the Occupational Values Inventory (OVI), a 30-item measure that expands the content coverage of work values by linking into a broad range of O*NET occupational descriptors, including Work Activities and Work Contexts, along with salary data from the Bureau of Labor Statistics. The OVI assesses 11 work values—Interpersonal, Outdoor, Physical, Leadership, Salary, Prestige, Variety, Interest, Work Hours, Knowledge Utilization, and Autonomy—providing an updated and refined coverage of work values relevant to people and occupations in the modern labor market. Study 1 (N = 768) developed and refined the OVI’s scales using conceptual and psychometric criteria, also reporting …

Brief Virtual Reality And Mixed Reality Mindfulness Breathing Exercise For Emotional Well-Being And Cognitive Functions In University Students: Within-Subjects Experimental Design Study, Zoey Khai Yee Eun, Charmaine Jiali Koh, Hwajin Yang, Adalia Yin Hui Goh, Meilan Hu, K Tennakoon Appuhamillage Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

Background: Mindfulness has been shown to enhance emotional well-being and cognitive performance, yet much of this evidence stems from interventions requiring prolonged practice, making them time-consuming and less accessible. Recent studies suggest that brief mindfulness sessions may also yield positive outcomes, but the effectiveness of such interventions in virtual reality (VR) and mixed reality (MR) remains underexplored. Objective: This study investigates the effects of brief mindfulness breathing exercises delivered through VR and MR on attentional and emotional restoration and self-control capacity. Methods: Using a within-subjects experimental design, 102 undergraduate participants (n=83, 81.4% female; mean age 20.87, SD 1.89) completed a …

Understanding Critical Thinking In Generative Artificial Intelligence Use: Development, Validation, And Correlates Of The Critical Thinking In Ai Use Scale, Gabriel R. Lau, Wei Yan Low, Louis Tay, Ysabel Thereze Ang Guevarra, Dragon Gašević, Andree Hartanto

Research Collection School of Social Sciences

Generative AI tools are increasingly embedded in everyday work and learning, yet their fluency, opacity, and propensity to hallucinate mean that users must critically evaluate AI outputs rather than accept them at face value. The present research conceptualises critical thinking in AI use as a dispositional tendency to verify the source and content of AI-generated information, to understand how models work and where they fail, and to reflect on the broader implications of relying on AI. Across six studies ( N = 1341), we developed and validated the 13-item critical thinking in AI use scale and mapped its nomological network. …

Log Off To Level Up: The Effect Of Social Media Hiatus On Goal Pursuit, Nekysha L. Y. Jalil, Yong Han Tan, Andree Hartanto, Eddie M. W. Tong

Research Collection School of Social Sciences

Concerns are growing that social media, with its constant notifications and attention-grabbing content, may distract individuals and hinder progress toward important goals. Despite its pervasive presence in our lives, the impact of social media on goal achievement has not been thoroughly studied. This within-subject experimental study aims to investigate the effects of social media hiatus (SMH), a short abstinence from social media usage, on goal pursuit processes. Participants (N= 107) completed daily diaries over three consecutive days of SMH and three days of regular social media use. SMH was manipulated by blocking participants’ access to multiple social media platforms. The …

The Restorative Effects Of Nature Exposure Via Virtual Reality On Well-Being, Self-Control, And Working Memory, Zoey K. Y. Eun, Hwajin Yang, Nicole R. Y. Chen, Andree Hartanto

Research Collection School of Social Sciences

The psychological benefits of nature exposure are vital for well-being in an increasingly urbanised world. While previous research has consistently demonstrated the restorative effects of natural environments on both physical and psychological health, findings on virtual nature simulations remain mixed, possibly due to the limited immersive quality of conventional displays. Virtual reality (VR), however, provides immersive visual and auditory engagement, making it a promising alternative for delivering nature-based experiences when direct exposure to real nature environments is unavailable. The present study examined the effects of VR-simulated nature on attentional and emotional restoration and self-control capacity, using a preregistered, within-subjects experimental …

A Scalable Model For Resident And Faculty Well-Being: Applying Self-Determination Theory And The Job Demands-Resources Framework In Graduate Medical Education, Gregory Guldner, Adam Neufeld

HCA Healthcare Journal of Medicine

Despite growing attention to burnout in graduate medical education (GME), many institutional efforts remain fragmented and lack theoretical coherence. In response, HCA Healthcare developed a system-wide initiative grounded in Self-Determination Theory (SDT) and the Job Demands-Resources (JD-R) framework to guide leadership development, learning climate improvement, and resident and faculty well-being. What began as a single-program effort evolved into a multi-year, system-wide initiative involving more than 5800 residents across 366 programs at 85 hospitals. In collaboration with workplace psychologists from Claremont Graduate University and Immersyve Health, the initiative integrated theory-informed leadership workshops, validated assessment platforms, and continuous quality-improvement processes to help …

Psychological Research on Urban Society

Emotions in Urban Society: A Call for Papers for Psychological Research on Urban Society (PRoUSt)

Hemispheric Processing Of Words And Unfamiliar Symbol Strings, Karoline Curlo

Celebrating Scholarship and Creativity Day (2018-)

This study investigates the role of each cerebral hemisphere in processing word forms to better understand how the brain decodes letter strings. Participants completed a same-different judgment task for four-character word and symbol (Orkhon) pairs presented unilaterally. On different trials, a single character was substituted at the first, second, third, or fourth position in the string. Results showed a sameness advantage in the left hemisphere (LH) and a difference advantage in the right hemisphere (RH) - effects only observed with word stimuli. Performance was best when the substituted character occurred at the beginning or end of words and symbols, rather …

What Makes Leaders In Human Services Effective? A Pilot Study Linking Systems Thinking, Perspective-Taking, And Leadership Success, Ryan Witterschein

Journal of Nonprofit Innovation

Leadership effectiveness is a persistent challenge in human services nonprofits, where organizations serving individuals with disabilities and complex needs have grown dramatically but lack validated tools for assessing the cognitive competencies that distinguish effective leaders. This quantitative pilot study introduces the ABA Leadership Assessment Tool version 2.0 (ABLA 2.0), a 48-item instrument integrating transformational and transactional leadership frameworks with three constructs from Relational Frame Theory—perspective-taking, temporal reasoning, and systems thinking. Eight Board Certified Behavior Analysts in organizational leadership roles completed the assessment, yielding 100% completion and strong preliminary reliability across all subscales (α = .71–.94). Leaders who demonstrated stronger cognitive …

Narratives From Law Enforcement Officers Who Leave Policing, Hector Rene Matascastillo

Walden Dissertations and Doctoral Studies

Beginning in May 2020, a national exodus of law enforcement officers (LEOs) from the profession occurred. There has been speculation about the causes, including social unrest and trauma, while some claim that there has always been this level of attrition. The purpose of this study was to capture the narratives of LEOs regarding what motivated them to leave the profession after May 2020 and before achieving their retirement goals. The theoretical lens of general strain theory guided this study, as it posits that people under great strain resort to options that they would not usually consider, such as leaving the …

Cultural Perspectives On Work-Life Balance: A Literature Review Of Cultural Differences Relating To Work-Family Conflict And Occupational Well-Being, Emma Rosengartner

Honors Theses

The focus of this review is to explore four different cultural views on work-life balance (WLB) and work-family conflict (WFC). The terms WLB and WFC have become increasingly popular in the business world as people struggle to separate their home life and work life due to technology blurring the lines and women becoming an equal force in the workplace. When individuals experience high levels of WFC or do not have stable WLB, well-being is often negatively affected and work performance declines. This review explores literature on WLB and WFC in Japan, Mexico, Sweden, and the United States to make connections …

Personal Tendencies And Traveler Preferences: A Study On Personality-Driven Travel Marketing, Evelyn Filleman

Honors Theses

This study examines the influence of personality typing (as outlined by the International Personality Item Pool test structure) on travel decision-making as it relates to marketing matrix strategies. Understanding the relationship between personality type and travel is crucial, as individuals will have different need hierarchies and place decision-making factors on different levels of priority. This study uses the theoretical frameworks of Clifford Geertz and Michael Pacanowsky (Cultural Approach to Organizational Communication) and Judee Burgoon (Expectancy Violations Theory) to inform, direct, and explain the results of the completed research. A total of 261 participants were asked to take a survey outlining …

The Hollywood Rap And Trap Culture Industry And Its Portrayal Of Crime, Youth Socialization, And Anti-Social Behavioral Norms, Ishika Sen

Honors Theses

This thesis synthesizes and reflects on media effects and hip-hop studies to examine how the Hollywood rap/trap industry participates in the influence of normalization of crime and anti-social behaviors, substance use, and the sexualization of women among youth (ages 13–21). I integrate analytic evidence on media violence with lyric/content analyses of rap and critiques of the criminal justice system in hip-hop. Specific subtopics from my outline include: theoretical frameworks (media-violence, social learning, cultivation, cultural criminology); corporate marketing and social-media amplification; youth vulnerability; and three patterned domains which include substance abuse, gun violence, and the sexualization of women, often leading to …

Therapists’ Perspectives On Female Patients’ Recovery From Sexual Violent Trauma Committed By Familiar Offenders, Lauren S. Doran

Walden Dissertations and Doctoral Studies

A mental health therapist is a licensed professional who is trained to identify any barriers or regression during the recovery process with their female patients’ psychological experiences from sexual violent trauma (SVT) perpetrated by a degree of familiar offenders. In this study, the therapists’ perceptions identified the impact of the SVT committed by a familiar offender toward the female victim’s recovery process. The theoretical foundation included betrayal trauma theory, moral injury, and victimology. The research question addressed how therapists described the psychological recovery of female patients who experienced sexual violence by a familiar offender. The research design was data collection …

Health-Related Quality Of Life Of Women With Polycystic Ovary Syndrome In Malaysia, Stephanie Yang

Walden Dissertations and Doctoral Studies

Polycystic ovarian syndrome (PCOS) is the most prevalent endocrine condition among women of reproductive age. PCOS is known to be a chronic disease that presents significant physical and body image issues, which in turn are associated with lowered emotional and health-related quality of life. Previous studies point to widespread dissatisfaction and delays with the diagnosis of PCOS and a lack of information provided by doctors. This phenomenological study was guided by Wilson and Cleary’s model of health-related quality of life to explore the health-related quality of life in Malaysian women with PCOS. Seven Malaysian women aged 29 to 50 years …

The Sacrificial Vs. The Luzhinian Figure: Comparing Sacrificial Love In Crime And Punishment, Pride And Prejudice, And A Tale Of Two Cities, Natalie Rose Kubala

Masters Theses

Many works of art and literature exploring the theme of love focus on trying to define what love is; in contrast, this thesis dives deeper into defining what love is not, specifically focusing on the relationship between love and sacrifice. This thesis argues that love is not the same as sacrifice because a true sacrifice requires that love is already present prior to the sacrifice being made. This thesis will compare those who perform true sacrifices to those who perform sacrifices for their own personal gain by exploring grandiose narcissistic characters who perform (or attempt to perform) sacrifices without love …

Positive Factors Of Resilience In Marginalized Families, Amanda K. Rigsby

Doctoral Dissertations and Projects

The current study examined underexplored factors of resilience that help individuals overcome trauma. The study gathered insights from individuals in marginalized communities through semi-structured interviews and collected qualitative data for thematic analysis from 15 participants. The study identified polyvictimized individuals’ perspectives on (a) resilience, (b) regulation, (c) sense of purpose, and (d) mindfulness. Exploring the relationship between these areas could broaden our understanding and, in turn, inform targeted interventions through further studies. This study collected qualitative data through semi-structured interviews with individuals in the Appalachian region. The Resilience Portfolio Model has been used in research to identify mindfulness, regulation, sense …

The Role Of Emotional Intelligence And Defense Mechanisms In Processing Childhood Experiences And Their Impact On Adulthood, Lauren M. Williams

Doctoral Dissertations and Projects

Early childhood relationships significantly influence developmental and relational functioning across the lifespan. Emotional intelligence has been associated with healthier relational outcomes through increased awareness of self and others. Variability in childhood experiences may contribute to the development of defense mechanisms that shape how individuals process relational memories and regulate emotional distress in adulthood. Limited research has examined how emotional intelligence and defense mechanisms interact to influence adults’ retrospective processing of childhood experiences, including attachment, rumination, and motivation. The present quantitative correlation study examined the relationships among emotional intelligence, defense mechanisms, childhood attachment experience, rumination, and motivation in a sample of …

Bridging The Intention-Behavior Gap: A Quasi-Experimental Study Of A Hapa-Based Approach To Reducing Sedentary Behavior And Improving Productivity In Remote Employees, Laurel Lb Long

Doctoral Dissertations and Projects

The rise of remote work has increased sedentary behavior (SB), which is associated with negative health and organizational outcomes. Physical activity (PA) can mitigate these risks. Therefore, this quantitative quasi-experimental study examined changes in PA, SB, and productivity associated with a 6-week Health Action Process Approach (HAPA)-based intervention, informed by Self-Determination Theory (SDT) and Nudge Theory, among remote employees. The intervention was delivered asynchronously and targeted both motivational and volitional components of behavior change. A one-group pretest-posttest design required participants to complete the Occupational Sitting and Physical Activity Questionnaire (OSPAQ; N = 21) and the Health and Work Performance Questionnaire …

Mindful Tea Drinking As A Low-Cost Sensory Intervention For Reducing Stress In College Students, David Gabel

Honors Projects

The proposed study would investigate the effects of a tea-based sensory mindfulness exercise on stress in college aged participants. Participants would listen to a mindful tea exercise and a non-mindful tea exercise after a mild stress-inducing Stroop test. For both conditions, the participants would report their current state of distress on the Subjective Units of Distress Scale (SUDS) before and after each tea exercise and their heart rate variability (HRV) would be measured during each segment of the experiment.

Descriptive statistics and a paired samples t-test would be used to compare the mindful tea condition with the non-mindful condition following …

Psychological Contract And Perma Well-Being, Ryan T. Roddey

Doctoral Dissertations and Projects

The PERMA model, a five-factor framework- positive emotion (P), engagement (E), relationship (R), meaning and purpose (M), and accomplishment (A)- was developed to assess the building blocks of well-being (Seligman & Csikszentmihalyi, 2000). In the workplace setting, organizations perceive how positive organizational psychology shapes employee well-being through exchange relationships (Donaldson et al., 2022). Previous research confirms the effect of the psychological contract on well-being when the contract is violated in the workplace. Yet, limited studies examine the association between overall well-being and employee exchange agreements, such as the psychological contract. This study explored the differences between relational and transactional psychological …

Age Of First Smartphone Ownership With Social Media Access And Its Impact On Mental Health Outcomes, Derrick W. Swandol

Doctoral Dissertations and Projects

The purpose of this quantitative study was to examine the relationship between the age of smartphone ownership with social media access (ASO) and self-esteem and depression symptoms, as well as to determine if the results could be moderated by adverse childhood experiences (ACEs) as an individual transitions from adolescence to adulthood. The study was conducted with n=54 (72% female), of whom 83% first owned a smartphone with social media access ≥ 12 years-of-age. This study was unable to obtain the minimum sample size for a statistically significant study and is considered underpowered due to needing a minimum sample size of …
