Item and Test Characteristic Curves of Rank-2PL Models for Multidimensional Forced-Choice Questionnaires
Applied Measurement in Education, v37 n3 p272-288 2024
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. Some examples of ICC and TCC plots from a real pair form and triplet form are provided, and they appear to help identify misfit trait scores at the item and test levels. TCC plots with negative statements changed to positive ones are also proposed.
