Differential Item Functioning: its Multidimensional Model and Resulting Sibtest Detection Procedure
Behaviormetrika, 1996 A multidimensional model of differential item functioning (DIF) developed by Shealy and Stout is presented. It explains how individual items combine to produce differential test functioning (DTF) at the test level. Recent developments based on this approach, including development of the DIF/DTF detection procedure SIBTEST, are surveyed.
