Detection of Differential Item Functioning in Multidimensional Testing Using IRT-Residual DIF Framework

• In Event: Electronic Board Session II

Abstract

We explore the IRT-residual based DIF (RDIF) detection method in multidimensional testing contexts. Given its promising performance in the preliminary simulation, along with appealing features like computational simplicity and no need for separate item calibration, the RDIF framework can be an effective methodology for assessing DIF within multidimensional testing environments.
