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

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

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 measure of PTSD symptom severity. The purpose of this study was to determine whether college student (n = 255) and MTURK (n = 316) samples are invariant on the PCL-5. Model fit indices indicated the 7-factor Hybrid model was the best fitting model, but the 6-factor anhedonia model was the most parsimonious model. Both models demonstrated equivalence in factor structures (configural invariance), factor loadings (metric invariance), intercepts (scalar invariance), and residuals (strict invariance), indicating MTURK and college student samples are similar in regards to PTSD symptom severity. These findings provide evidence that these groups can be combined in future studies to increase sample size for trauma research. Only the Anhedonia factor exhibited mean differences between groups, which may be related to true differences between college students and MTURK survey-takers. Thus, there is …

Coaching Athletes with Post-Traumatic Stress: Exploring Trauma-Related Competencies and Coaching Efficacy (open access)

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

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 stigma of persons with PTS has on coaching efficacy specific to coaching trauma-impacted athletes (i.e., trauma-informed coaching efficacy), after controlling for general coaching experience. Descriptive statistics indicated the majority of coaches had no trauma-specific education, a high degree of familiarity with PTS, and a low level of stigma via four attribution variables. Moreover, participants highly appraised their own emotional intelligence, the quality of their coach-athlete relationships, and their trauma-informed coaching efficacy. A hierarchical regression analyses indicated that familiarity with PTS helped to explain additional variance in trauma-informed coaching efficacy over and above demographic and general coach experience variables. The study establishes trauma-informed coaching as a distinct area of research and highlights the need for improved continuing education opportunities for coaches related to psychological trauma and PTS.

Mixed Development and Validation of an Authentic Assessment for Middle School Mathematics (open access)

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

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 classes from a large suburban school district in the Southwest United States. A sample of teachers (n = 14), rated students (n = 110) using a pilot rubric of 187 items. Analyses resulted in a 32-item rubric with 20 themes and 9 factors. Results from a G-study revealed the facet that best explained variance in student scores was the interaction between raters and assessment units, as well as students and assessment units. As part of the development of the assessment, a content validity exercise revealed 18% of the rubric items as below average quality. Findings highlight the need to enhance contextualization of rubrics, use a strategy of assessment that includes contextualized and decontextualized assessment, and to investigate the role of utilization deficiency in explaining low student scores.

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

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

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; (3) emotional involvement; (4) indirect care; and (5) positive engagement. Then regression analyses were conducted to understand how and to what extent the five domains of father involvement reported by mothers and mothers' perceived social support influenced Chinese immigrant mothers' parenting stress. In addition, an indirect effects of mothers' self-efficacy on the relation between fathers' involvement and mothers' parenting stress was also tested. The results showed that Chinese mothers reported significantly greater level of fathers' emotional involvement than the same type of involvement reported by Chinese immigrant fathers. This study also found that fathers' emotional involvement reported by Chinese immigrant mothers was a significant predictor of Chinese immigrant mothers' parenting stress. However, mothers' perceived social support was a stronger predictor, accounting for more variance in their parenting stress than their reports of fathers' involvement …

Evaluating Program Diversity and the Probability of Gifted Identification Using the Torrance Test of Creative Thinking (open access)

Evaluating Program Diversity and the Probability of Gifted Identification Using the Torrance Test of Creative Thinking

Multiple criteria systems are recommended as best practice to identify culturally, linguistically, economically diverse students for gifted services, in which schools often incorporate measures of creativity. However, the role of creativity in identification systems and its recruitment of diverse student populations is unclear. The Torrance Test of Creative Thinking (TTCT) is the most widely used norm-referenced creativity test in gifted identification. Although commonly used for identifying talent, little is known on the variability in composite scores on the TTCT-Figural and student demographics (i.e., race/ethnicity, sex, socioeconomic status, English language learning status). This study evaluated student demographic subgroup differences that exist after the initial phase of an identification process (i.e., universal screening, referrals) and examined the relationship among student demographics (i.e., race/ethnicity, free/reduced lunch status, English language learning status, sex), cognitive ability, academic achievement, and creativity, as measured by the TTCT-Figural Form A or B, to the probability of being identified for gifted programs. In a midsized school district in the state of Texas, findings indicate several demographic differences for students who were referred or universally screened across the measures of cognitive ability, academic achievement, and creativity. However, there were lower differences when using the TTCT-Figural. Results of a hierarchical generalized …

Lived Experiences of Families of University Students Amid a Pandemic Response (open access)

Lived Experiences of Families of University Students Amid a Pandemic Response

This study explores students' and their families' experiences during the pandemic response to COVID-19 by the higher education community. Using the hermeneutic phenomenological approach, we employed two open-ended surveys and semi-structured interviews of 16 parent-college student dyads (N = 34). The study draws on students' and parents' retrospective accounts beginning Spring 2020 through the Fall 2020 semesters. Families experienced a disruptive event initialized by the ebb and flow of information. Students' experiences varied based on their expectations and academic classification. The most consistent family challenges were the displacement of students and parents from their physical education and work locations while having to maintain student and occupation responsibilities. The educational experience was inconsistent and dependent on each professors' capacity to engage the students in the online environment. Students expressed feelings of loss of their student and educational experiences, but most students felt the spring courses prepared them to continue their education. Assignments due at random times and poor communication about expectations inhibit students from having dedicated time to interact and make memories. Most families adapted to the new normal by supporting the family members' identities as students and employees and ensuring everyone had the resource needed to succeed. Families experienced monotony …

Flipping Scripts: Mentoring for Secondary Readers (open access)

Flipping Scripts: Mentoring for Secondary Readers

Researchers have reported that a variety of socio-cultural interventions can be used to increase positive attitudes toward reading for secondary students. A socially constructed reading intervention could add learning growth for a reluctant reading population. This study examines whether secondary students experience a measurable increase in positive attitudes toward reading after engaging in modeling and mentoring sessions with a much younger student and whether there is a perceivable difference in the secondary students' attitude following this mentoring activity. A variation of the one-way ANOVA, the Mann-Whitney U test, was completed to determine whether there was a statistically significant difference between these groups of students after participating in the reading intervention plan. It was determined that a small increase was found in one of the domains. The measurement survey is divided into four measured components that align with Albert Bandura's model for self- efficacy. The results from this study indicated growth in only one of the measures, however, some of the outcomes in the other measures suggested potential growth in attitudes with a relaxation of these necessary experimental strictures. A limitation of this research was the change from face-to-face tutoring completed by the secondary student with elementary students in an afterschool …

"All things at once":  A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals (open access)

"All things at once": A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals

The purpose of this phenomenological study was to explore how individuals from different multiracial/multiethnic groups experience and process the phenomenon of parental racial ethnic socialization (RES). Critical multiracial race theory, critical race theory, and bioecological systems theory offered a conceptual framework to how RES is often presented and processed. This study was guided by two research questions: (1) What are the experiences of RES among multiracial individuals? and (2) How do multiracial individuals process the parental racial ethnic socialization they were offered? Nine qualitative, one-on-one, semistructured interviews were conducted with individuals from three different multiracial/multiethnic groups. Results revealed that experiences of RES varied along with how participants processed RES. Three subthemes and one theme emerged related to the RES experiences of participants. For some participants lack of conversations were evident in their RES, which meant that conversations surrounding multiraciality and other racialized topics were not present. Other participants disclosed the subtheme of preparedness as part of their RES experience, while others mentioned the importance of environment to their RES experience. Additionally, the theme of changes over time arose, demonstrating how different life events can impact RES experiences. As for how multiracial/multiethnic individuals process RES experiences, the main theme of identity …

Factor Retention Strategies with Ordinal Variables in Exploratory Factor Analysis: A Simulation (open access)

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

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 partial, parallel analysis, and empirical Kaiser criterion) resulting in a 2 × 2 × 2 × 2 × 2 × 3 × 3 × 4 × 5 design that totals to 5,760 condition combinations tested over 1,000 replications each. Results show that each retention method performed worse when utilizing polychoric correlation matrices. Moreover, minimum average partials are quite sensitive to factor loadings and overall perform poorly compared to parallel analysis and empirical Kaiser criterion. Empirical Kaiser criterion performed almost identical to parallel analysis in normally distributed data; however, performed much worse under highly skewed conditions. Based on these findings, it is recommended to use parallel analysis utilizing principal components analysis with a Pearson correlation matrix to determine the number of factors to retain when dealing with ordinal data.

Bringing Them Back: Using Latent Class Analysis to Re-Engage College Stop-Outs

Half of the students who begin college do not complete a degree or certificate. The odds of completing a degree are decreased if a student has a low socio-economic status (SES), is the first in a family to attend college (first-generation), attends multiple institutions, stops out multiple times, reduces credit loads over time, performs poorly in major-specific coursework, has competing family obligations, and experiences financial difficulties. Stopping out of college does not always indicate that a student is no longer interested in pursuing an education; it can be an indication of a barrier or several barriers faced. Institutions can benefit themselves and students by utilizing person-centered statistical methods to re-engage students they have lost, particularly those near the end of their degree plan. Using demographic, academic, and financial variables, this study applied latent class analysis (LCA) to explore subgroups of seniors who have stopped out of a public four-year Tier One research intuition before graduating with a four-year degree. The findings indicated a six-class model was the best fitting model. Similar to previous research, academic and financial variables were key determinants of the latent classes. This paper demonstrates how the results of an LCA can assist institutions in the decisions …

Using a Slopes Difference Test to Probe Longitudinal Multilevel Interactions in an Aptitude-Treatment or Skill-by-Treatment Context: A Simulation

In order to determine which interventions work best for which students, precision education researchers have examined aptitude-treatment interactions (ATI) or skill-by-treatment interactions (STI) by using multiple regression analysis. In recent years, technological innovation and greater accessibility to more advanced statistical techniques have allowed researchers to examine ATI or STI using longitudinal mixed modeling. Probing techniques for interaction effects like slopes difference tests fit well with an ATI or STI framework, but the power of using a slopes difference test in longitudinal mixed models is unknown. The current study used the simulation method to determine which factors influence the power of a slopes difference test in a longitudinal mixed model. Specifically, the study examined design conditions such as number of waves, number of clusters and participants per cluster, effect size, intraclass correlation, variances and covariance of the random effects, and proportion of treatment to non-treatment participants. These were examined in order to help ATI and STI researchers understand whether the slopes difference test in a longitudinal mixed model is sufficiently powered for their sample and study. Effect size, number of waves, number of clusters, and participants per cluster were found to be strong determinants of power and significantly impacted model convergence …
