Multidimensional CAT Item Selection Methods for Domain Scores and Composite Scores: Theory and Applications
Peer reviewed Peer reviewed
Direct linkDirect link
Yao, Lihua – Psychometrika, 2012
Multidimensional computer adaptive testing (MCAT) can provide higher precision and reliability or reduce test length when compared with unidimensional CAT or with the paper-and-pencil test. This study compared five item selection procedures in the MCAT framework for both domain scores and overall scores through simulation by varying the structure…
