The article “Rejoinder to McNeish and Mislevy: What Does Psychological Measurement Require?” by Klaas Sijtsma, Jules L. Ellis, and Denny Borsboom provides a detailed response to criticisms and discussions raised by McNeish and Mislevy regarding the role and application of the sum score in psychometric practices. The authors address core …
Understanding differential item functioning (DIF) is critical for ensuring fairness in assessments across diverse groups. A recent study by Li et al. introduces a method to enhance the interpretability of DIF items by incorporating response process data. This approach aims to improve equity in measurement by examining how participants engage …
Lawrence T. DeCarlo’s recent article introduces a psychological framework for mixed-format exams, combining signal detection theory (SDT) for multiple-choice items and item response theory (IRT) for open-ended items. This fusion allows for a unified model that captures the nuances of each item type while providing insights into the underlying cognitive …
Nguyen and Waller’s (2024) study provides an in-depth analysis of factor-rotation local solutions (LS) within multidimensional, two-parameter logistic (M2PL) item response models. Through an extensive Monte Carlo simulation, the research evaluates how different factors influence rotation algorithms’ performance, contributing to a deeper understanding of multidimensional psychometric models. Background The study …
Item Response Theory (IRT) is a widely adopted framework in psychological and educational assessments, used to model the relationship between latent traits and observed responses. This recent work introduces an innovative approach that incorporates group-theoretic symmetry constraints, offering a refined methodology for estimating IRT parameters with greater precision and efficiency. …
This article discusses a Bayesian hierarchical framework for the Two-Parameter Logistic (2PL) Item Response Theory (IRT) model. By introducing hierarchical priors for both respondent abilities and item parameters, this method offers a detailed perspective on latent traits. Additionally, the use of Automatic Differentiation Variational Inference (ADVI) makes the approach scalable …
Leifeng Xiao and Kit-Tai Hau’s article, “Performance of Coefficient Alpha and Its Alternatives: Effects of Different Types of Non-Normality,” examines how coefficient alpha and other reliability indices perform under varying conditions of non-normality. The study offers critical insights into how these measures behave across different data structures, providing useful recommendations …
Jari Metsämuuronen’s (2022) article introduces a significant advancement in how reliability is estimated within psychological assessments. The study critiques traditional methods for their tendency to yield deflated results and proposes new attenuation-corrected estimators to address these limitations. This review examines the article’s contributions and its implications for improving measurement precision. …
Liang’s (2020) study on Bayesian Structural Equation Modeling (BSEM) focuses on the use of small-variance normal distribution priors (BSEM-N) for analyzing sparse factor loading structures. This research provides insights into how different priors affect model performance, offering valuable guidance for researchers employing BSEM in their work. Background Bayesian Structural Equation …
The study by Xiao and Bulut (2020) evaluates how different methods for handling missing data perform when estimating ability parameters from sparse datasets. Using two Monte Carlo simulations, the research highlights the strengths and limitations of four approaches, providing valuable insights for researchers and practitioners in educational and psychological measurement. …
