Refining effect size measures and classification for differential item functioning: Toward unified guidelines across methods

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Differential Item Functioning (DIF) analysis is used to identify potentially biased items in multi‐item measurements. In addition to testing the statistical significance, it is essential to evaluate the practical significance of DIF through effect size measures.

Multidimensional unipolar IRT and applications to the measurement of print exposure

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Item response theory (IRT) has been a prominent modelling framework in educational and psychological measurement. Traditional IRT models are bipolar, commonly assuming symmetric measurement link functions and symmetric trait distributions over a latent continuum unbounded at both ends. However, many measured constructs, such as print exposure,

The 18 Household Food Security Survey items provide valid food security classifications for adults and children in the Caribbean

BMC Public Health, 2006
Background We tested the properties of the 18 Household Food Security Survey (HFSS) items, and the validity of the resulting food security classifications, in an English-speaking middle-income country.

A Comparison of Linking Methods for Longitudinal Designs with the 2PL Model Under Item Parameter Drift

Applied Measurement in Education
This study investigates the longitudinal linking of dichotomous item responses at three time points, focusing on the performance of Haberman linking, Haebara linking, Stocking-Lord linking, and concurrent calibration in the presence of item parameter drift (IPD). Two general linking approaches, joint and chain linking, are examined.

On the asymmetry, complexity and predicted data patterns of nontraditional item response theory models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Traditional item response theory (IRT) models involve symmetric response probability functions, but a developing area of research has focused on asymmetric alternatives. To date, these studies have focused primarily on introducing new asymmetric models, detailing their mathematical formulations, explaining how to interpret their item ...

Integrating Global Citizenship Into Mathematics Education: Development and Validation of a Scenario‐Based Assessment

School Science and Mathematics, EarlyView.
ABSTRACT This study develops and validates a scenario‐based assessment for global citizenship within mathematics contexts. It addresses the need for students to engage thoughtfully with global challenges by linking civic education and mathematics. The assessment tool captures competencies essential for global citizenship, including presenting opinions ...

SIMEX-Based and Analytical Bias Corrections in Stocking–Lord Linking

Analytics
Stocking–Lord (SL) linking is a popular linking method for group comparisons based on dichotomous item responses. This article proposes a bias correction technique based on the simulation extrapolation (SIMEX) method for SL linking in the 2PL model in ...

Modeling Item Responses to Understand Change over Time and Diagnostic Needs in Tandem

Journal of Educational Measurement, Volume 63, Issue 3, Fall 2026.
Abstract Achievement tests are often designed to measure student growth over time using vertical scales while also providing diagnostic information on mastery of specific skill areas. However, traditional assessments rarely integrate psychometric models appropriate for both purposes.

Tutorial on Analyzing Patient‐Reported Outcome Measures in Clinical Development

Clinical and Translational Science, Volume 19, Issue 8, August 2026.
ABSTRACT Patient‐reported outcomes (PROs) are now considered essential components of clinical development and regulatory assessment. Despite their widespread collection, PRO data remain under‐utilized, with analyses often limited to descriptive summaries or single time‐point comparisons that fail to capture the richness, longitudinal structure, and ...
