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

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). Additionally, problematic results can occur with the use of maximum likelihood (ML) estimation in GMMs, including convergence issues and sub-optimal maxima. In such cases, Bayesian estimation may prove to be a useful solution. The present Monte Carlo simulation study aimed to assess class enumeration accuracy and parameter recovery of GMMs with a TVC, particularly when a TVC has been incorrectly specified as a TIC. Both ML estimation and Bayesian estimation were examined. Results indicated that class enumeration indices perform less favorably in the case of TVC misspecification, particularly absolute class enumeration indices. Additionally, in the case of TVC misspecification, parameter bias was found to be greater than the generally accepted cutoff of 10%, particularly for variance estimates. It is recommended that researchers continue to use a variety of class enumeration indices during …

Using Kidpower® Social Narratives to Teach Individuals with Autism about Bullying

Individuals with autism spectrum disorder (ASD) are at an increased risk to be victims of bullying due to the core characteristics of the disorder. Prior research has focused on understanding bullying from the perspectives of individuals with ASD, parents, and practitioners through interviews and questionnaires. However, limited evidence exists using interventions to teach individuals with ASD about how to identify and respond to bullying. This study employed Kidpower® bullying narratives to teach individuals with ASD how to identify and respond to various bullying scenarios. Kidpower was selected to provide practitioners with a pre-established curriculum to utilize, rather than creating materials for each student. A multiple probe design across three participants was utilized to (a) teach individuals with ASD how to identify and respond to bullying drawings on Kidpower narratives, and (b) add an experimental study to the limited literature base pertaining to strategies for teaching about bullying to individuals with ASD. A fourth participant was also included as a case study. Progress for all participants was measured using the percentage of correct responses to 10 questions. Three out of four participants reached the mastery criterion of 90% over two consecutive sessions. Sessions for the fourth participant concluded after seven intervention …

Reading and Mathematics Growth Patterns of High-Achieving Students: An Investigation of School-Year and Summer Trends (open access)

Reading and Mathematics Growth Patterns of High-Achieving Students: An Investigation of School-Year and Summer Trends

Rambo-Hernandez and McCoach's analysis into the longitudinal growth of high-achieving students offered two conclusions about the reading growth of high achieving students: high-achieving students lose less ground in reading during the summer, but they exhibit less growth over the school year. This study will seek to replicate the reading results of the Rambo-Hernandez and McCoach's study and include an analysis of mathematics growth with initially high-achieving, third grade students in both the school and summer months. Through a three-level hierarchical linear model covering 1541 third graders, this study analyzes the differences between the school year and summer growth rates of the high-achieving students against other students that scored above the mean on MAP assessments. Students identified as being in the top 10% nationally at the start of the third grade grew less over the course of the school year compared to their peers in both mathematics and reading but showed signs of accelerated growth at the end of the study.

Measuring Creativity in Academic Writing

The demand for a creative workforce has never been higher, yet schools struggle to teach and assess creativity among students predictably and efficiently. Compositions are an effective way to incorporate creativity across the curriculum; however, essays are time consuming for teachers to score for objective quality or subjective creativity. In this study, I explored a) if high creativity scores are related to high quality and sophistication in academic writing, and b) if extant text-mining tools effectively identify quality, sophistication, and creativity in academic essays. I collected 230 essays written by Grade 11 students. Four human-raters analyzed these essays for quality, sophistication, and creativity, and I used text-mining tools designed to assess creativity to analyze the same. Using correlations - including the variables semantic distance (measured against the GloVe corpus), entropy (measured with Shannon's Entropy Index), and idea density (measured with CPIDR5.1) - I assessed both human-raters' and text-mining tools' proficiency at identifying quality, sophistication, and creativity in academic essays. Quality, sophistication, and creativity were also regressed on these same text-mining variables to assess which method - human or computer – and which of the text-mining tools - best predicts these dependent variables. Human-raters' creativity scores correlated with human-raters' quality scores …

Did the COVID-19 Pandemic Make Better Parents? A Qualitative Exploration of Parents' Experiences during an Historic Period (open access)

Did the COVID-19 Pandemic Make Better Parents? A Qualitative Exploration of Parents' Experiences during an Historic Period

Predicated on the literature, parenting practices are subject to change following high-impact events. This understandably applies to the COVID-19 pandemic, a calamity of sheer magnitude. Despite the presence of maladaptive parenting behaviors in the pandemic, upsides (e.g., compassionate parenting practices, strengthened child-parent bond) did transpire as well. The present study is focused on whether and how parental betterment occurred and unfolded during the pandemic. The explicit research goal is to elucidate what positive parental responses and changes were and what drove those responses and changes. The study employed the phenomenological study to make a fine-grained inquiry into the researched phenomenon. Fourteen parents of varying demographic characteristics constituted the sample. One-on-one semi-structured interviews were conducted over Zoom for data collection. Thematic analysis was performed to code the data. I eventually constructed four themes: (1) targeted parental responses and changes, (2) refined parenting skills and practices, (3) heightened understanding of children and parenting, and (4) unsettled parenting styles. Each theme reflects a critical facet of the parenting experiences during the pandemic. In the discussion, effort is invested in parsing out what could elevate the quality of parental responses and what may contribute to the positive parental changes, as well as in pointing …

The Relationship between Racial Colorblindness and the Self-Reported Implementation of Multicultural Teaching Practices among Teachers of Gifted Students (open access)

The Relationship between Racial Colorblindness and the Self-Reported Implementation of Multicultural Teaching Practices among Teachers of Gifted Students

Culturally responsive instruction is recommended as a tool to help mitigate disparities in the recruitment and retention of culturally diverse students in gifted programs. However, the endorsement of colorblind racial ideology has been associated with lower multicultural teaching competency and the adoption of deficit perspectives among teachers. In addition to informing teachers' perceptions of students' abilities and potential, endorsing colorblind racial ideology may make it more difficult for teachers to recognize disparities that adversely impact students from traditionally minoritized and underrepresented groups. The current study examines the relationship between colorblind racial attitudes and multicultural teaching competency among teachers of students who have been identified as gifted and talented. In a large sample of Texas teachers, multiple regression analysis was used to examine the relationship between colorblind racial ideology, multicultural teaching knowledge, and the implementation of culturally responsive teaching practices when teaching gifted and talented students. Results indicate that racial colorblindness, sex, and multicultural teaching knowledge are all significant predictors of the self-reported implementation of culturally responsive instruction, while gifted-specific training and the proportion of students of color had no effects. Implications relate to the necessity of addressing teachers' racial beliefs and ensuring that gifted-specific professional development equips teachers with the …

Influence of Quiet Eye Self-Training on Internal Processes and Performance Outcomes (open access)

Influence of Quiet Eye Self-Training on Internal Processes and Performance Outcomes

Use and effectiveness of the quiet eye (QE) technique has been a topic of interest in sport, exercise, and performance psychology. The primary purpose of this study was to investigate the influence of QE self-training on college students' internal processes associated with performing a novel task. Specifically, college students' internal processes were examined to understand how QE self-training influenced performance on a novel aiming task. College students (N = 106; M = 21.84 ± 1.79) voluntarily participated in QE self-training intervention. Participants' self-efficacy, self-regulation, and mindfulness was examined before and after QE self-training intervention over a 7-week period, with performance being measured weekly. Following intervention, interviews and follow-up survey were used to gather information about perceptions of using QE self-training instruction. Results indicated outcome performance improved from pre- to post-intervention. Additionally, participants mindfulness acting with awareness and non-judging of inner experiences was influenced by QET self-training. Findings from this study may help sport coaches and performance psychology professionals provide attentional focus training instruction to individuals with diverse levels of skills while also providing future directions for applied practice and research.

A Mixed-Method Sequential Explanatory Study of Fundamental Motor Skills Competence of Underserved Preschool Children (open access)

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

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 (Mage = 4.32, SD = 0.63; girls 56.5%). This methodology allowed for a follow-up qualitative aspect to explore the influence of parents' perceptions and behaviors on their child's FMS competence and health outcomes in a subsample of eight parent–child dyads who demonstrate high or low FMS competence in the quantitative data. The results of this dissertation suggest that preschoolers' FMS competence, especially locomotor skills, were associated with and predicted various health outcomes in sedentary behavior (β = -0.21), light physical activity (β = 0.23), executive function (β = -0.21), and perceived motor competence (β = 0.34). No significant influences of FMS competence on moderate-to-vigorous, body fatness, HRQoL were found (p > 0.05). We also found that positive parental influences (role modeling, support, and facilitation) were observed more often among preschoolers in the high FMS …

Caregiver Knowledge of Risk Factors Associated with Complex Congenital Heart Disease and Quality of Life Outcomes (open access)

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

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, which is drastically impacting the need to support quality of life outcomes for a child with cCHD and their family. The two most prevalent unaddressed risks for quality of life outcomes in the cCHD population are child and caregiver mental health and child's neurodevelopmental disabilities.

The Role of Maternal Health Literacy within Mother-Preterm Infant Attachment: A Meta-Analysis of Maternal Sensitivity Interventions

The present study systematically reviewed and statistically summarized the current body of literature on the relationship between maternal health literacy and maternal sensitivity, and the effect of these two variables on mothers' care and decision making on distal attachment outcomes. In so doing, a systematic review of the extant peer-reviewed, published literature examining the effectiveness of interventions in effort to improve health literacy and maternal sensitivity, with a focus on increasing the quality of mother-preterm infant attachment outcomes, was undergone. This was followed by four multilevel random effects meta-analyses. Results indicated that mothers who participated in health literacy (maternal sensitivity) interventions had, on average, higher attachment quality, in comparison to those who did not participate. Additionally, maternal age was found to be a statistically significant predictor of the overall average effect size. This suggests that maternal health literacy may be a yet unexplored correlate of mother-preterm infant attachment outcomes.

Predictors of Academic Success in an Early College Entrance Program (open access)

Predictors of Academic Success in an Early College Entrance Program

Early college entrance programs have existed in the United States since the 1950s, but in-depth research on academic success in these programs is lacking. Every year, early college entrance programs utilize a variety of data-gathering and candidate-screening techniques to select hundreds of students for admission into these accelerated programs. However, only a smattering of research articles has discussed the factors that predict academic success in these programs. This exploratory study investigated commonly-relied-upon admissions data points—such as high school GPA and ACT scores—and demographic information—such as sex, ethnicity, and locality—to see if any of these factors predicted academic success: namely, graduation and early college entrance program GPA. Secondary data from nearly 800 students admitted over an 11-year period to a state-supported, residential early college entrance program located at a large Southern university in the United States were utilized for this study. Logistic regression failed to yield a model that could accurately predict whether or not a student would graduate from the program. Multiple regression models showed that high school GPA and ACT scores were predictive of performance, and that factors like locality and ethnicity can have predictive power as well. However, the low variance in performance explained by the variables included …

Exploring the Association of Language Brokering and Parent-Child Relationship in Korean Immigrant Families (open access)

Exploring the Association of Language Brokering and Parent-Child Relationship in Korean Immigrant Families

This study focuses on investigating the dynamics of language brokering as Korean immigrant families experience environmental challenges associated with immigration. This study was conducted with qualitative research design with purposive sampling of Korean immigrant families. Six parent-child dyads were recruited and participating children were between 12 to 16 years old. Semi-structured interviews were conducted separately with parents and children in either English or Korean. Thematic analysis was employed for analyzing the transcribed interviews. The Dedoose software program was applied to assist the coding process. 12 subthemes were revealed under four main themes, which were aligned to the study's research questions. The twelve subthemes included parents' dependence on children, vulnerability and resilience of Korean immigrant families, children's socioemotional development through language brokering, and the role of first-born daughter in the family. Parent and child responses indicated how language brokering affects can be a risk in relation to children's development (i.e., with responsibility of language brokering leading the child to experience stress or experience the responsibility of translation as a burden. Positively, respondents indicated that the parent and child experienced a greater sense of empathy for each other's roles. The results derived from this study were aligned with the results of previous …
