Simple matrix sampling planned missing (SMS PD) design, introduce missing data patterns that lead to covariances between variables that are not jointly observed, and create difficulties for analyses other than mean and variance estimations. Based on prior research, we adopted a new multigroup confirmatory factor analysis (CFA) approach to handle…

Bullying is a form of school violence that has recently received the attention of school psychologists. One of these problems that exists in almost all schools is the phenomenon of school bullying. The aim of this study is to examine the psychometric reliability and validity of the Participant Role Scale in bullying in Persian and compare the…

A recent review found that 11% of published factor models are hierarchical models with second-order factors. However, dedicated recommendations for evaluating hierarchical model fit have yet to emerge. Traditional benchmarks like RMSEA <0.06 or CFI >0.95 are often consulted, but they were never intended to generalize to hierarchical models.…

This dissertation compares the performance of equivalence test (EQT) and null hypothesis test (NHT) procedures for identifying invariant and noninvariant factor loadings under a range of experimental manipulations. EQT is the statistically appropriate approach when the research goal is to find evidence of group similarity rather than group…

Research in human development often relies on composites, that is, composed variables such as indices. Their composite nature renders these variables inaccessible to conventional factor-centric psychometric validation techniques such as confirmatory factor analysis (CFA). In the context of human development research, there is currently no…

Scholars study representative international surveys to understand cross-cultural differences in mentality patterns, which are measured via complex multi-item constructs. Methodologists in this field insist with increasing vigor that detecting "non-invariance" in how a construct's items associate with each other in different national…

The discussion of social responsibility has expanded from ethical conduct of research to include a broader range of topics including participating in the policy-making process, engaging in public discourse related to science, and promoting projects serving societal common goods. Although such an expanded framework on social responsibility is…

Fresh PhD recipients are experiencing restricted career opportunities yet the enrolment of PhD Scholars is increasing rapidly. Perhaps, doctoral students lack conscious educational decision-making. Building on such a perspective of doctoral students' unconscious educational choices, we explored their educational choices throughout their life…

This research seeks to understand the determinants of student dropout in the courses offered at the Open University of Brazil system at the Federal University of Santa Maria. The research used the following methods: survival function, factorial analysis, and logistic function. Results indicated that male students, with higher levels of income, who…

Creativity has long been emphasized as an essential skill identified and developed in classrooms by eminent psychologists. A high level of creativity is required to adapt to the changing world of innovation. University-level students are privileged as they get multiple opportunities to learn creative skills. They are facilitated with autonomy and…

The most common effect size when using a multiple-group confirmatory factor analysis approach to measurement invariance is [delta]CFI and [delta]TLI with a cutoff value of 0.01. However, this recommended cutoff value may not be ubiquitously appropriate and may be of limited application for some tests (e.g., measures using dichotomous items or…

In conducting confirmatory factor analysis with ordered response items, the literature suggests that when the number of responses is five and item skewness (IS) is approximately normal, researchers can employ maximum likelihood with robust standard errors (MLR). However, MLR can yield biased factor loadings (FL) and FL standard errors (FLSE) when…

The consistency of psychometric properties across waves of data collection provides valuable evidence that scores can be interpreted consistently. Evidence supporting the consistency of psychometric properties can come from using a longitudinal extension of item factor analysis to account for the lack of independence of observation when evaluating…

In this paper, a problem set activity focused on understanding and applying unsupervised and supervised chemometric methods for the analysis of biodiesel-diesel blended fuels is described. This problem set was utilized in two upper-level analytical elective courses aimed for junior and senior level students. The data set consists of peak areas…

In this study, an instrument was developed to measure an instructor's value and incorporation of intersectionality theory in the classroom. Through a Delphi study, a list of items was devised, and then a pilot study was conducted to collect responses from 161 participants. The result is the development of the Intersectionality Pedagogy Scale, a…
