Abstract

We will discuss how MIMIC (multiple indicators multiple cause) models for studying uniform and non-uniform differential item functioning (DIF) can be conceptualized as mediation and moderated mediation models. Conceptualizing DIF within the context of a moderated mediation model helps us to examine the potential causal process through which DIF occurs. In addition, this allows us to apply useful concepts and ideas from the moderated mediation literature, e.g., for (1) improving our understanding of uniform and non-uniform DIF as direct effects and indirect effects, and (2) clarifying an interpretation the uniform DIF parameter in the presence of non-uniform DIF. By conceptulizing DIF in this way, researchers can develop more exact hypotheses about DIF and interpret the parameters more clearly.
