Interpretation of Spurious Differential Item Functioning

, 2021
This article provides a causal graphical discussion that helps to fill the gap between statistical analysis of differential item functioning (DIF) and the substantive judgment of item fairness. Presented causal graphical representations that describe how the data were generated in a causal sense and the accompanying graphical explanation show a ...

An Investigation of Item Position Effects by Means of IRT-Based Differential Item Functioning Methods

International Journal of Assessment Tools in Education, 2021
In this study, whether item position effects lead to DIF in the condition where different test booklets are used was investigated. To do this the methods of Lord’s chi-square and Raju’s unsigned area with the 3PL model under with and without item ...

Simplifying the Assessment of Measurement Invariance over Multiple Background Variables: Using Regularized Moderated Nonlinear Factor Analysis to Detect Differential Item Functioning

Structural equation modeling : a multidisciplinary journal, 2019
Determining whether measures are equally valid for all individuals is a core component of psychometric analysis. Traditionally, the evaluation of measurement invariance (MI) involves comparing independent groups defined by a single categorical covariate (

DIFFERENTIAL ITEM FUNCTIONING: ITS CONSEQUENCES [PDF]

ETS Research Report Series, 2010
ABSTRACTThis report examines the consequences of differential item functioning (DIF) using simulated data. Its impact on total score, item response theory (IRT) ability estimate, and test reliability was evaluated in various testing scenarios created by manipulating the following four factors: test length, percentage of DIF items per form, sample sizes
