WebMay 1, 2024 · The IRT-based method appeared to recover the true threshold values effectively, although the precision deteriorated slightly when the prevalence was very small (< 0.05) or very large (> 0.95). WebItem response theory (IRT) is another widely used method for assessing DIF. IRT allows for a critical examination of responses to particular items from a test or measure. As noted earlier, DIF examines the probability of correctly responding to or endorsing an item conditioned on the latent trait or ability.
