Bayesian methods to infer model dimensionality in factor analysis generally assume a lower triangular structure for the factor loadings matrix. Consequently, the ordering of the outcomes influences the results. Therefore, we propose a method to infer model dimensionality without imposing any prior restriction on the loadings matrix. Our approach…

This paper reports on the development and validation of the classroom assessment (CA) for self-regulated learning (SRL) Questionnaire (CASRLQ), a questionnaire intended to measure to what extent CA practices are SRL supportive. The original CASRLQ, consisting of 32 items to represent five SRL-supportive CA dimensions, was constructed and…

Although item response theory (IRT) models such as the bifactor, two-tier, and between-item-dimensionality IRT models have been devised to confirm complex dimensional structures in educational and psychological data, they can be challenging to use in practice. The reason is that these models are multidimensional IRT (MIRT) models and thus are…

The factor structure and psychometric properties of the Identity Style Inventory-5 were evaluated with 579 college students of color. Exploratory and confirmatory factor analyses suggested a modified four-factor model with 18 items. Configural, metric, and scalar invariance of the modified model was supported across three racial/ethnic minority…

This manuscript details the development and exploratory factor analysis of a United States' version of the "International Survey of School Counselors' Activities" (ISSCA-US), a 42-item instrument that identifies activities of school counselors. Responses were collected from 390 US school counselors. Separate EFAs were conducted for two…

Researchers and practitioners sometimes presume that using a previously "validated" instrument will produce "valid" scores; however, contemporary views of validity suggest that there are many reasons this assumption can be faulty. In order to demonstrate just some of the problems with this view, and to support comparisons of…

Locus of Control (LOC) is a general term used in social and educational psychology to refer to the perceived source of control for behavioural outcomes. Since the 1980s, various instruments have been developed to measure this construct in relation to pro-environmental behaviours and action. In this article, we revisit the value of this construct…

The Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V; Wechsler 2014a) "Technical and Interpretation Manual" (Wechsler 2014b) dedicated only a single page to discussing the 10-subtest WISC-V primary battery across the entire 6 to 16 age range. Users are left to extrapolate the structure of the 10-subtest battery from the…

This article is a commentary on McGill et al.'s (2020) article "Use of Translated and Adapted Versions of the WISC-V: Caveat Emptor." McGill et al. use caveat emptor in their title to indicate that the buyer of an assessment must be careful about the product being purchased, presumably because the seller of the assessment is not being…

The Cattell-Horn-Carroll (CHC) taxonomy of cognitive abilities married John Horn and Raymond Cattell's Extended Gf-Gc theory with John Carroll's Three-Stratum Theory. While there are some similarities in arrangements or classifications of tasks (observed variables) within similar broad or narrow dimensions, other salient theoretical features and…

Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS™) is a tested strategy for improving communication and climate in hospitals. It is a promising but untested tool among school-based mental health teams. We examined the psychometric properties of the TeamSTEPPS Teamwork Perceptions Questionnaire (T-TPQ) and Teamwork…

Short forms of psychometric scales have been commonly used in educational and psychological research to reduce the burden of test administration. However, it is challenging to select items for a short form that preserve the validity and reliability of the scores of the original scale. This paper presents and evaluates multiple automated methods…

The State of Washington requires school districts to file court petitions on students with excessive unexcused absences. The "Washington Assessment of Risks and Needs of Students" (WARNS), a self-report screening instrument developed for use by high school and juvenile court personnel in such situations, purports to measure six facets of…

The aim of this article was to independently test the factor structure of the Early Childhood Environment Rating Scale, 3rd Edition (ECERS-3). Using a sample of 148 independent observations, Standard and Satorra--Bentler confirmatory factor analysis were used to determine if the ECERS-3 conformed to the structure published in its manual using a…

The Short Sensory Profile (SSP) is one of the most commonly used measures of sensory features in children with autism spectrum disorder (ASD), but psychometric studies in this population are limited. Using confirmatory factor analysis, we evaluated the structural validity of the SSP subscales in ASD children. Confirmatory factor models exhibited…
