In this article we present a new methodology for detecting Di erential Item Functioning (DIF). We introduce a DIF model, called the Random Item Mixture (RIM), that is based on a Rasch model with random item difficulties (besides the common random person abilities). In addition, a mixture model is assumed for the item difficulties such that the items may belong to one of two classes: a DIF or a non-DIF class. The crucial di fference between the DIF class and the non-DIF class is that the item difficulties in the DIF class may di ffer according to the observed person groups while they are equal across the person groups for the items from the non-DIF class. Statistical inference for the RIM is carried out in a Bayesian framework. The performance of the RIM is evaluated using a simulation study in which it is compared with traditional procedures, like the Likelihood Ratio test, the Mantel-Haenszel procedure and the standardized p-DIF procedure. In this comparison, the RIM performs better than the other methods. Finally, the usefulness of the model is also demonstrated on a real life dataset. [less ▲]

Differential item functioning (DIF) is an important issue of interest in psychometrics and educational measurement. Several methods have been proposed in the last decades to identify items that function differently between two (or more) groups of examinees. Starting from a framework for classifying DIF detection methods and from a comparative overview of the most traditional methods, an R package for nine methods, called difR, is presented. The commands and options are briefly described, and the package is illustrated through the analysis of a data set on verbal aggression. [less ▲]
