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.

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 ...

Bias-Corrected Root Mean Square Deviation Estimators

Foundations
The root mean square deviation (RMSD) is a widely used item fit statistic in item response models. However, the sample RMSD is known to exhibit positive bias in small samples. To address this, seven alternative bias-corrected RMSD estimators are proposed

The Journey from Likert to Forced-Choice Questionnaires: Evidence of the Invariance of Item Parameters

Journal of Work and Organizational Psychology, 2019
Multidimensional forced-choice questionnaires are widely regarded in the personnel selection literature for their ability to control response biases. Recently developed IRT models usually rely on the assumption that item parameters remain invariant when ...

Implementation Aspects in Simulation Extrapolation-Based Stocking–Lord Linking

Applied Sciences
Stocking–Lord (SL) linking is commonly used for group comparisons based on dichotomous item responses. Recently, the simulation extrapolation (SIMEX) method for SL linking has been introduced within the two-parameter logistic (2PL) model to reduce the ...

Comparing Weighted RMSD, Weighted MD, Infit, and Outfit Item Fit Statistics Under Uniform Differential Item Functioning

Mathematics
In educational large-scale assessment studies, uniform differential item functioning (DIF) across countries often challenges the application of a common item response model, such as the two-parameter logistic (2PL) model, to all participating countries ...
