Correlates of Communalities as Matching Variables in Differential Item Functioning Analyses

Multivariate matching in Differential Item Functioning (DIF) analyses may contribute to understand the sources of DIF. In this context, detecting appropriate additional matching variables is a crucial issue. This present article argues that the variables which are correlated with communalities in item difficulties can be used as an additional matching variable in DIF analyses. To examine this claim, mathematics data from the Program for International Student Assessment (PISA) was analyzed. Out of school time students spent for learning was detected as an additional matching variable. Multivariate DIF results showed that this variable might be related to the source of DIF in some items. (Contains 1 figure and 2 tables.)
