Workplace Loneliness And The Impact Of Social Connections In Distributed Teams, Belkys Stallings

Walden Dissertations and Doctoral Studies

Workplace loneliness is a growing organizational challenge as the rise of distributed teams reshapes opportunities for social connection and engagement. Business leaders need to understand this challenge because it is associated with reduced belonging, lower job satisfaction, diminished productivity, and increased turnover intentions. The purpose of this quantitative correlational study was to examine the extent to which distributed team environments (remote, hybrid, or flexible) impacted workplace loneliness and whether social connectedness moderated this relationship. Social exchange theory, self-determination theory, and Weiss’s concept of loneliness grounded this study. The participants comprised 84 adults working full-time in distributed team environments across the …

Cbd's Impact On Learning, Memory, And Anxiety: A Dose Response, Audrey Camacho

Psychology ETDs

Cannabidiol (CBD) is widely utilized for its therapeutic properties, yet its impact on an unmanipulated model at baseline behavior remains poorly understood. This study investigates CBD’s dose-dependent behavioral profile on spatial learning, memory, and anxiety using Long-Evans rats. Subjects received a vehicle, 20 mg/kg, or 40 mg/kg CBD dose prior to assessment in the Morris Water Task (MWT) and Elevated Plus Maze (EPM). MWT results indicated consistent Day 1 learning, but the 40 mg/kg dose induced a temporary disruption 24 hours post-treatment. Performance returned to baseline by day 6. On the EPM, traditional anxiety markers remained unchanged. While CBD did …

Assessment And Classification Of Idiosyncratic Behavioral Sequences In Rodent Navigation, Max G. Segal

Psychology ETDs

The Morris Water Task (MWT) has been the gold standard assessment of place learning and memory for over four decades, yet the processes that contribute to successful navigation are not completely understood. It is generally posited that rats learn to navigate directly to a place; however, navigation is not perfectly direct but contains variation in swim speed and trajectory resulting in efficient, yet suboptimal paths. Gonçalves-Garcia et al. (2024) demonstrated that path topography is quantitatively similar across trials within individual rats for a given start location, and dissimilar between rats and different start locations within rat. This suggests rats may …

Peer Attachment And Popularity Among Adolescents: The Mediating Role Of Relational Aggression, Katherine S. Fosco, Bailee Hill, Yan Li, Michelle F. Wright

DePaul Discoveries

Popularity during adolescence may pose a challenging social barrier, involving the desire for exclusivity and the need for broader peer connections. This study investigated the longitudinal effects of peer attachment on popularity among adolescents and the mediation process of relational aggression, expecting that peer attachment would be linked to reduced relational aggression, in turn relating to lower popularity at a later time point. The research participants (N = 569) included adolescents between the ages of 11 and 15 in the United States with data collection occurring at three time points. The path from Time 1 peer attachment to Time 2 …

Mothers’ Childhood Maltreatment And Developmentally Appropriate Attributions Of 12-Month-Old Infants, Katelyn M. Lamberton

Undergraduate Theses, Capstones, and Recitals

This study examined associations between developmentally appropriate attributions (DAAs), an understudied construct, with maternal history of childhood maltreatment and maternal reflective functioning (RF) with their 12-month-old infants. The study examined if 1) DAAs at 12 months were concurrently associated with parental RF at 12 months for construct validity, and 2) higher levels of maternal childhood maltreatment were associated with lower DAAs for predictive validity. Participants were 156 mothers (40.0% White, 25.5% Latinx, 14.9% Black, 5.5% Asian, 2.1% Native-American, 12.0% biracial/multiracial) and their 12- to 15-month infants. Childhood maltreatment and RF were assessed by parental self-report at three-months and 12-months postpartum …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Testing The Christian University Belonging Scale: Revision From Target Population Feedback., Jasmine Bowles

Honors Projects

This study explored whether feedback from a scale’s target population can improve its psychometric qualities. We developed a psychological scale of Christian university belonging, defined as feelings of being accepted, valued, engaged and connected in direct association with the faith-integration at a Christian university. Three studies were executed. First, we collected and analyzed quantitative data (n=55) on the 14-item scale and reduced the number of items to six. Second, we collected and analyzed qualitative data from students attending a Christian university in the Pacific Northwestern United States (n=7) on the 6-item version to revise the scale. After revision, the scale …

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. …

Examining The Glat As A Measure Of Ai Literacy, Hunter R. Castleton

Masters Theses, 2020-current

The current study examined the Generative AI Literacy Assessment Test (GLAT) as a promising test of AI literacy due to its content, which is grounded in relevant AI literacy theory, and its design as a cognitive measure of AI literacy. To examine the GLAT, data were collected from a sample of 543 graduating seniors at James Madison University (JMU) who took the GLAT as part of a longer series of tests. Their responses were first analyzed to assess the test’s item characteristics and internal structure. Following this initial analysis, a final item set was established to ensure that low-quality items …

The Impact Of Free Vs. Fixed Factor Correlations On Parameter Recovery In Multidimensional Irt Models, Stephanie Leroy

Dissertations, 2020-current

This dissertation investigated how cross-loading specification and factor-correlation treatment influence parameter recovery in multidimensional item response theory (MIRT) models. Two simulation studies extended Hosseinzadeh and Cole (2024) by examining whether freely estimating factor correlations improves recovery of item parameters, factor correlations, and latent traits. Study 1 used a compensatory multidimensional two-parameter logistic (M2PL) model with two correlated dimensions and 20 dichotomous items. Manipulated conditions included cross-loading specification (correctly specified vs. ignored), proportion of cross-loaded items, magnitude of cross-loadings, true factor correlation, and factor-correlation treatment during estimation (freely estimated vs. fixed to zero). Study 2 extended the design to a multidimensional …

Latent Transition Analysis: A Statistical Method For Identifying Underlying Subgroups Over Time, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers working in early childhood research are often interested in assessing change over time in multiple variables. In addition, they may wish to ascertain whether there exist subgroups in the data with respect to these variables, and whether/how membership in these groups is related. Latent transition analysis (LTA) provides such researchers with a useful tool for investigating questions around such groups, including their composition, frequency, and the likelihood of moving from one to another at different points in time. The purpose of this manuscript is to provide a full demonstrate of LTA and show how it can be used to …

Comparison Of Multidimensional Models For Extreme Response Styles, Holmes Finch, Brian French

Perspectives on Early Childhood Psychology and Education

Self-administered scales are ubiquitous throughout the social sciences. Therefore, it is crucial that they properly reflect the measured latent trait(s), and are not influenced by other factors. One potential threat to validity is the response style favored by an individual completing the items. In particular, a tendency to engage in extreme responding (ERS) can result in a tendency to provide responses in the outer range of the response scale, independent of the actual level of the response to the item. The purposes of this study was to demonstrate how these models can be used to account for ERS in practice, …

A Tutorial For Identifying And Comparing Change Points In Developmental Trajectories, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers in a variety of social science fields work with sequential data, such as measurements made over time. In some instances, one or more of the moments (e.g., mean, variance) of the series may change abruptly at some point in the sequence, yielding what is known as a change point. There is a broad literature describing methods for changepoint detection. Researchers working with multiple sequential series containing change points may be interested in comparing the locations of these changes. The purpose of this manuscript is to demonstrate how a researcher can detect changepoints and compare changepoints between two or more …

Using Multilevel Modeling To Understand Nested Data, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers in the social sciences often work with nested data, in which individuals are collected in higher level clusters. For example, educational research often involves working with samples in which students are nested within schools. Standard data analyses, such as regression and analysis of variance (ANOVA), yield statistically biased results when this nested structure is ignored. One widely used and effective approach for handling such nested data is multilevel modeling. The purpose of this manuscript is to review the basics of multilevel modeling and to provide the reader with a fully worked example in which the analytic approach and results …

Using Effect Sizes, Confidence Intervals, And The Bayes Factor To Better Understand The T-Test, Analysis Of Variance, And Regression Results, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Null hypothesis testing is a widely used paradigm for assessing research hypotheses across the social sciences. Despite their ubiquity, researchers have discussed a number of problems and limitations to hypothesis testing and have suggested alternatives that might provide greater depth and explanation of research results. The purpose of this paper is to describe the use of several such alternatives and to show how they can be integrated with one another and with null hypothesis testing in order to provide a more holistic view of research hypotheses.

Theses and Dissertations

This study examined psychological vulnerability and fear of crime in 538 adults from Trinidad and Tobago. Perceived risk was the strongest predictor of fear, while prospective intolerance of uncertainty predicted fear directly. Mediation was supported among Afro-Trinidadians but not Indo-Trinidadians, suggesting sociocultural differences in cognitive pathways linking vulnerability to fear.

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …

The current study examined the relationship between stress and sleep in preschool-aged children and sought to evaluate associations between children’s stress and sleep, as well as parental psychopathology (i.e., anxiety and depression). Participants included N = 609 parents and their children ages three to five at Time 1. 368 of whom participated again when children were ages six to eight years old at Time 2. Participants completed study questionnaires, and children’s hair samples were taken to assess cortisol …

Understanding Human Arm Stiffness Modulation In Overground Phri: The Roles Of Kinematics, Perturbation, And Trunk Sway, Mohsen Mohammadi Beirami, Sambad Regmi, Devin Michael Burns, Yun Seong Song

Psychological Science Faculty Research & Creative Works

This study examines human arm kinematics during overground physical human-robot interaction (pHRI). Previous work showed humans adjust arm stiffness with changing trajectory uncertainty, but the roles of arm kinematics and muscle activation remained unclear. Building on a preliminary study, we analyzed arm movements with more participants (10 individuals) to achieve more reliable findings and examined two potential influences that arose in the preliminary study: the robot's perturbation effect (a brief hand push) and left-to-right trunk sway. Using a linear mixed-effects model, we evaluated the effects of participant, block, and trajectory condition on arm angles. Results showed minimal kinematic contribution to …

Pro-Environmental Behavior: Its Moderating Role On The Relationship Between Environmental Identity And Climate Change Anxiety Among Gen Z Filipinos, Marc Eric S. Reyes, Alvin Joseph D. Mapoy, Victoria Ann Louis N. Aranzanso, Francheska Ysabel A. Avera, Beatrice O. Martinez, Mariah Michaela T. Ramos, Ryan Francis O. Cayubit

Makara Human Behavior Studies in Asia

Environmental identity refers to an individual’s understanding of how their environment shapes their identity and relationships. This connection may cause climate change anxiety and motivate pro-environmental behavior. Using an explanatory, cross-sectional design, we examined whether environmental identity (EI) predicts climate change anxiety (CCA) and whether pro-environmental behavior (PEB) moderates their relationship. Seven hundred sixty-one Filipinos aged 18–25 completed the Revised Environmental Identity Scale, Climate Change Anxiety Scale, and Pro-Environmental Behavior Scale. Our findings revealed a significant positive relationship between environmental identity and anxiety about climate change. However, moderation analysis indicated that environmental identity is only associated with climate change anxiety …
