Many test developers try to ensure the content validity of their tests by having external experts review the items, e.g. in terms of relevance, difficulty, or clarity. Although this approach is widely accepted, a closer look reveals several pitfalls need to be avoided if experts' advice is to be truly helpful. The purpose of this paper is to…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…

The aim of the study is to examine the influence of students' psychotypes on their learning using digital educational technologies within the Metaverse. In the course of the longitudinal experimental study, the results of the initial testing of 79 students during their undergraduate studies and the re-testing of 75 of these students during their…

Existing educational assessments have typically been developed without appropriate attention to the intended and unintended consequences of measure implementation and interpretation. We are developing the Expanding Screening to Support Youth (ESSY) Whole Child Screener using a mixed methods approach that attends to the intended and unintended…

Studies have used psychological games testing to measure children's bioaffinity (a child's love of/for or connection to nature) as a result of time spent in nature enriching children's well-being. Discrepancies found between two studies in different countries (Sweden and Canada) informed this research. Both studies used the same bioaffinity…

Often, important decisions regarding accountability and placement of students in performance categories are made on the basis of test scores generated from tests, therefore, it is important to evaluate the validity of the inferences derived from test results. One of the threats to the validity of such inferences is aberrant responding. Several…

The purpose of this systematic review was to characterize the implementation of reliability generalization meta-analytic (RGM) practices within mathematics education-related empirical research. RGM studies are used to investigate and generalize the reliability of a measure across various studies. An exhaustive literature search was conducted to…

Across the country, school districts are increasingly seeking out privately contracted psychologists to conduct psychological evaluations. As such, it is increasingly important that psychological reports adhere to best practices and are written to ensure comprehension by both parents and teachers. This study explored the potential differences…

Determining eligibility for the special education category Emotional Disturbance (ED) is a challenging task. The difficulty in identifying students with ED is due, in part, to problematic federal criteria (Olympia et al., 2004; Skiba, Grizzle, & Minke, 1994). Unchanges since 1975, these criteria have created an environment in which…

Recent research in multidimensional item response theory has introduced within-item interaction effects between latent dimensions in the prediction of item responses. The objective of this study was to extend this research to bifactor models to include an interaction effect between the general and specific latent variables measured by an item.…

In his focus article, "Rethinking Traditional Methods of Survey Validation," published in this issue of "Measurement: Interdisciplinary Research and Perspectives," Andrew Maul introduces and discusses several foundational issues and concludes that self-report measures may be particularly difficult to validate and may fall short…

Response-time models are of increasing interest in educational and psychological testing. This article focuses on the lognormal model for response times, which is one of the most popular response-time models, and suggests a simple person-fit statistic for the model. The distribution of the statistic under the null hypothesis of no misfit is proved…

Response-time models are of increasing interest in educational and psychological testing. This paper focuses on the lognormal model for response times (van der Linden, 2006), which is one of the most popular response-time models, and suggests a simple person-fit statistic for the model. The distribution of the statistic under the null hypothesis…

This study presents new models for item response functions (IRFs) in the framework of the D-scoring method (DSM) that is gaining attention in the field of educational and psychological measurement and largescale assessments. In a previous work on DSM, the IRFs of binary items were estimated using a logistic regression model (LRM). However, the LRM…
