A Model-Based Standardization Approach that Separates True Bias/DIF from Group Ability Differences and Detects Test Bias/DTF as Well as Item Bias/DIF.
Shealy, Robin; Stout, William
Psychometrika, v58 n2 p159-94 Jun 1993
A model-based modification of the standardization index based on a multidimensional item response theory bias modeling approach is presented that detects and estimates differential item functioning (DIF) (item bias) simultaneously for several items as well as differential test functioning (DTF). This SIBTEST procedure is tested through a computer simulation. (SLD)
