Imogene: These articles might help a bit - they are concerned with the inevitable appearance of artificial DIF in most methods of detecting DIF.

Subject: [Rasch] Plain language articles about DIF interpretation issues?
I am looking for some plain language articles about the complexity around identifying (true) DIF . I've been reading (Everett?) Smith's chapter in "Introduction to Rasch Measurement " edited by same and I have a bare grasp of the issues presented. I was hoping someone could recommend a few review articles or chapters that could clarify and expand on the issues he raises and conclusions made, especially with respect to the argument that sometimes items that appear neutral after a DIF analysis may actually be biased. I don't have a degree in mathematics..am much better with words ;-) , so am trying to look for articles that have a smattering rather than a littering of formulae to make the point.
