| Abstract | A modification of the SIBTEST procedure to assess differential item functioning (DIF) for two-dimensional test data (i.e., data for tests where two intended abilities are tapped by test items) is described. A small simulation study is carried out to assess the performance of the modified SIBTEST to detect DIF in such two-dimensional data. The simulation study results indicate that the modified SIBTEST has exhibited good adherence to the nominal level of significance for cases where there are two intended abilities with no DIF present, while exhibiting high power for cases where there are two intended abilities with DIF present. The results are discussed with implications for future research. (Contains 2 tables and 17 references.) (Author/SLD) |
