Measuring Item Influence for Diagnostic Classification Models

Posted: | Daniel P. Jurich, Matthew J. Madison

Educational Assessment

 

This study proposes four indices to quantify item influence and distinguishes them from other available item and test measures. We use simulation methods to evaluate and provide guidelines for interpreting each index, followed by a real data application to illustrate their use in practice. We discuss theoretical considerations regarding when influence presents a psychometric concern and other practical concerns such as how the indices function when reducing influence imbalance.
