Evaluation of Linking Methods for Multidimensional IRT Calibrations
Min, Kyung-Seok
Asia Pacific Education Review, v8 n1 p41-55 Apr 2007
Most researchers agree that psychological/educational tests are sensitive to multiple traits, implying the need for a multidimensional item response theory (MIRT). One limitation of applying a MIRT in practice is the difficulty in establishing equivalent scales of multiple traits. In this study, a new MIRT linking method was proposed and evaluated by comparison with two existing methods. The results showed that the new method was more acceptable in transforming item parameters and maintaining dimensional structures. Limitations and cautions in using multidimensional linking techniques were also discussed. (Contains 8 figures and 3 tables.)
