AN ELEMENTARY TEST OF THE NORMAL 2PL MODEL AGAINST THE NORMAL 3PL ALTERNATIVE [PDF]

ETS Research Report Series, 2006
ABSTRACTA simple score test of the normal two‐parameter logistic (2PL) model is presented that examines the potential attraction of the normal three‐parameter logistic (3PL) model for use with a particular item. Application is made to data from a test from the Praxis™ series.

Psychometric validation of the informed consent assessment scale using item response theory and factor analysis [PDF]

Frontiers in Medicine
ObjectivesInformed consent is a central ethical and legal practice in medicine, yet communication skills specific to this task are under-assessed in undergraduate medical education. This study aimed to develop and validate the informed consent assessment

Comparing Robust Linking and Regularized Estimation for Linking Two Groups in the 1PL and 2PL Models in the Presence of Sparse Uniform Differential Item Functioning

Stats, 2023
In the social sciences, the performance of two groups is frequently compared based on a cognitive test involving binary items. Item response models are often utilized for comparing the two groups. However, the presence of differential item functioning (DIF) can impact group comparisons.

The Rank-2PL IRT Models for Forced-Choice Questionnaires: Maximum Marginal Likelihood Estimation with an EM Algorithm

Journal of Educational and Behavioral Statistics
The rank two-parameter logistic (Rank-2PL) item response theory models refer to a set of models applying the 2PL model in a sequential ranking process that occurs in forced-choice questionnaires. The multi-unidimensional pairwise preference with 2PL model (MUPP-2PL) is a Rank-2PL model for items with two statements.

An investigation of enhancement of ability evaluation by using a nested logit model for multiple-choice items [PDF]

Anales de Psicologia, 2017
Multiple-choice items are wildly used in psychological and educational test. The present study investigated that if a multiple-choice item have an advantage over a dichotomous item on ability or latent trait evaluation.

Item and Test Characteristic Curves of Rank-2PL Models for Multidimensional Forced-Choice Questionnaires

Applied Measurement in Education
A process is proposed to create the one-dimensional expected item characteristic curve (ICC) and test characteristic curve (TCC) for each trait in multidimensional forced-choice questionnaires based on the Rank-2PL (two-parameter logistic) item response theory models for forced-choice items with two or three statements.

Asymptotic standard errors for reliability coefficients in item response theory. [PDF]

Br J Math Stat Psychol
Abstract In a recent review, Liu et al. (Psychological Methods, 2025b) classified reliability coefficients into two types: classical test theory (CTT) reliability and proportional reduction in mean squared error (PRMSE). This article focuses on quantifying the sampling variability of these coefficients under item response theory (IRT) models.

Information Functions of Rank‐2PL Models for Forced‐Choice Questionnaires

Journal of Educational Measurement, 2023
AbstractThis paper presents the item and test information functions of the Rank two‐parameter logistic models (Rank‐2PLM) for items with two (pair) and three (triplet) statements in forced‐choice questionnaires. The Rank‐2PLM model for pairs is the MUPP‐2PLM (Multi‐Unidimensional Pairwise Preference) and, for triplets, is the Triplet‐2PLM.

Investigating Measurement Invariance by Means of Parameter Instability Tests for 2PL and 3PL Models [PDF]

Educational and Psychological Measurement, 2018
M-fluctuation tests are a recently proposed method for detecting differential item functioning in Rasch models. This article discusses a generalization of this method to two additional item response theory models: the two-parametric logistic model and the three-parametric logistic model with a common guessing parameter.
