Abstract

The Mantel-Haenszel (MH) procedure is sensitive to only one type of differential item functioning (DIF). It is not designed to detect DIF that has a nonuniform effect across trait levels. By generalizing the model underlying the MH procedure, a more general DIF detection procedure has been developed (Swaminathan & Rogers, 1990). This study compared the performance of this procedure-the logistic regression (LR) procedure-to that of the MH procedure in the detection of uniform and nonuniform DIF in a simulation study which examined the distributional properties of the LR and MH test statistics and the relative power of the two procedures. For both the LR and MH test statistics, the expected distributions were obtained under nearly all conditions. The LR test statistic did not have the expected distribution for very difficult and highly discriminating items. The LR procedure was found to be more powerful than the MH procedure for detecting nonuniform DIF and as powerful in detecting uniform DIF. Index terms: differential item functioning, logistic regression, Mantel-Haenszel statistic, nonuniform DIF, uniform DIF.
