Modeling Effects of Differential Item Functioning in Polytomous Items.
Wang, Wen-Chung
Journal of Applied Measurement, v1 n1 p63-82 2000
Extended conventional two-group differential item function (DIF) analysis for dichotomous items to factorial DIF analysis for polytomous items where multiple grouping factors with multiple groups in each are analyzed jointly. Simulation studies and analysis of a real data set with 1,924 subjects show the parameters of the proposed modeling can be recovered in a satisfactory way. (SLD)
