Class Enumeration and Parameter Bias in Growth Mixture Models with Misspecified Time-Varying Covariates: A Monte Carlo Simulation Study

Description: Growth mixture modeling (GMM) is a useful tool for examining both between- and within-persons change over time and uncovering unobserved heterogeneity in growth trajectories. Importantly, the correct extraction of latent classes and parameter recovery can be dependent upon the type of covariates used. Time-varying covariates (TVCs) can influence class membership but are scarcely included in GMMs as predictors. Other times, TVCs are incorrectly modeled as time-invariant covariates (TICs). Additi… more

Institutional Pluralism and the Organization's Response: A Case Study of Chinese Women's Ice Hockey

Description: In recent years, the sport of women's ice hockey is growing fast worldwide. Upon winning the bid to host the 2022 Winter Olympics, women's ice hockey in China started to develop rapidly. However, the development of women's ice hockey in China has encountered numerous challenges. These challenges include addressing traditional Chinese culture, gender norms, and the process of sport reform. This study used a qualitative case study methodology to examine the perspectives of Chinese women ice hocke… more

Comparing Raw Score Difference, Multilevel Modeling, and Structural Equation Modeling Methods for Estimating Discrepancy in Dyads

Description: The current study focused on dyadic discrepancy, the difference between two individuals. A Monte Carlo simulation was used to compare three dyadic discrepancy estimation methods across a variety of potential research conditions, including variations on intraclass correlation, cluster number, reliability, effect size, and effect size variance. The methods compared were: raw score difference (RSD); empirical Bayes estimate of slope in multilevel modeling (EBD); and structural equation modeling es… more

Measurement Invariance of a Posttraumatic Stress Disorder Symptoms Measure (PCL-5) in College Student and Amazon's Mechanical Turk Samples

Description: College student and Amazon's Mechanical TURK (MTURK) samples are regularly utilized in trauma research. Recent literature, however, has criticized these samples for not being generalizable to the general U.S. population. Measurement invariance (MI) using confirmatory factor analyses (CFA), is rarely utilized in trauma research, even though the analysis can determine whether groups are invariant across factor structure, factor loadings, item intercepts, and residual error variances on a given me… more

Teachers' Perceptions of Professional Development: A Mixed Methods Study

Description: Research has identified job context, specific attributes of professional development (PD), and perceived teacher input as factors that contribute to teachers' attitudes. This sequential mixed methods study tested those findings together and further investigated teachers' beliefs and attitudes about their own professional learning. The first phase of data collection included a 5-item attitude survey, demographic information, and two short-answer questions. Multiple regression analysis of the sam… more

Coaching Athletes with Post-Traumatic Stress: Exploring Trauma-Related Competencies and Coaching Efficacy

Description: The purpose of this study was twofold: (a) assess cycling coaches' trauma-related competencies, as measured by trauma knowledge (i.e., trauma-specific education, familiarity with post-traumatic stress [PTS]), stigma of persons with PTS (i.e., fear/dangerousness, help/interact, forcing treatment, negative emotions), and interpersonal skills (i.e., self-reported emotional intelligence, perceived quality of coach-athlete relationships); and (b) examine the influence that trauma knowledge and stigm… more

Relationship between the Big Five and Creative Self-Beliefs in Undergraduates in Terms of College Enrollment and Major

Description: Supporting creativity in undergraduate education is important for the future development of society. To do this, an understanding of undergraduate characteristics is needed. A systematic literature review of the relationship between the Big Five personality factors and little-c creativity in undergraduates identified 19 studies. The creativity assessments within these investigations represented several conceptions of the construct with domain-general, self-reported measures of Person as most… more

Mixed Development and Validation of an Authentic Assessment for Middle School Mathematics

Description: In response to concerns about using only standardized multiple-choice assessments, some school districts have moved to using alternative ratings of student achievement with authentic assessments. However, such assessments are often limited in terms of the psychometric validity data supporting their use. The present study mixed quantitative and qualitative methods to examine the validity, development, and refinement of an authentic rating approach currently in use in middle school mathematics c… more

Mothers' Parenting Stress in Chinese Immigrant Families: The Role of Fathers' Involvement and Social Support

Description: This study investigated the association between Chinese immigrant mothers' reports of parenting stress and two sources of parenting support: fathers' support and social support. Five independent-samples t-tests were first computed to examine whether there were discrepancies between Chinese immigrant mothers' and fathers' perceptions of fathers' involvement across five domains of fathers' involvement in early child care: (1) fathers' warmth and attunement; (2) control and process responsibility;… more

Self-Reported Feelings of Shame and Fear of Failure among High Ability Undergraduates

Description: Understanding how emotions influence motivation among students is critical to the talent development process. Research shows that certain emotions elicit an approach motive while other emotions elicit an avoidance motive. This study explored emotional disposition and fear of failure among undergraduates enrolled in honors college (n = 63) compared to undergraduates enrolled in regular college courses (n = 296). Results suggest that dispositional shame is positively correlated with fear of failu… more

A Mixed-Method Sequential Explanatory Study of Fundamental Motor Skills Competence of Underserved Preschool Children

Description: This dissertation investigated the roles of early childhood fundamental motor skills (FMS) competence on physical, cognitive, and psychosocial health outcomes among underserved preschoolers in Head Start, and examined parental influence on their children's FMS competence. An explanatory sequential mixed methodology was used to examine the predictive strength of FMS competence on physical, cognitive, and psychosocial health outcomes among 216 underserved preschoolers from six Head Start centers … more

Caregiver Knowledge of Risk Factors Associated with Complex Congenital Heart Disease and Quality of Life Outcomes

Description: Congenital heart disease is the most common birth defect globally, affecting both children and their families. Twenty –five percent of children experiencing a CHD birth defect are diagnosed with complex CHD (cCHD), signifying critical heart dysfunction requiring one or more open-heart surgeries during the first year of life. With medical advances, cCHD survival rates have almost tripled in the last three decades. This has resulted in an increase in the number of morbidities associated with cCHD… more

Factor Retention Strategies with Ordinal Variables in Exploratory Factor Analysis: A Simulation

Description: Previous research has individually assessed parallel analysis and minimum average partial for factor retention in exploratory factor analysis using ordinal variables. The current study is a comprehensive simulation study including the manipulation of eight conditions (type of correlation matrix, sample size, number of variables per factor, number of factors, factor correlation, skewness, factor loadings, and number of response categories), and three types of retention methods (minimum average p… more
