Differential Item Functioning (DIF): Current Problems and Future Directions
Karami, Hossein; Salmani Nodoushan, Mohammad Ali
Online Submission, International Journal of Language Studies (IJLS) v5 n3 p133-142 2011
With the rising concerns over the fairness of language tests, Differential Item Functioning (DIF) has been increasingly applied in bias analysis. Despite its widespread use in psychometric circles, DIF is facing a number of serious problems. This paper is an attempt to shed light on a number of the issues involved in DIF analysis. Specifically, the paper is focused on four problems: (a) the inter-method indeterminacy, (b) the intra-method indeterminacy, (c) the ad hoc interpretations, and (d) the impact of DIF on validity. In order to orient the reader, the paper also provides a brief introduction to the fundamental concepts in DIF analysis.
