WebIn brief, differential item functioning (DIF) occurs when groups (such as defined by gender, ethnicity, age, or education) have different probabilities of endorsing a given item on a multi-item scale after controlling for overall scale scores. WebWe evaluate the item response theory with covariates (IRT-C) procedure for assessing differential item functioning (DIF) without preknowledge of anchor items (Tay, Newman, & Vermunt, 2011). This procedure begins with a fully constrained baseline model, and candidate items are tested for uniform and/or nonuniform DIF using the Wald statistic.
