Abstract
Comparison of the Mantel-Haenszel procedure versus the Loglinear models for detecting differential item functioning. A simulation study was carried out to compare the Mantel-Haenszel and the Loglinear procedures for detecting differentially functioning ítems. The procedures were applied in one single step and iteratively. The two main conclusions are: First, the Mantel-Haenszel procedure has higher power than the Loglinear procedures. Second, the iterative application of the procedures substantially improves detection rates and Type I error compared to single-step applications.
