Improving IRT Item Bias Detection with Iterative Linking and Ability Scale Purification.

Park, Dong-Gun; Lautenschlager, Gary J.

Applied Psychological Measurement, v14 n2 p163-73 Jun 1990

The effectiveness of two iterative methods of item response theory (IRT) item bias detection was examined in a simulation study. A modified form of the iterative item parameter linking method of F. Drasgow and an adaptation of the test purification procedure of F. M. Lord were compared. (SLD)
