Differential item functioning in the figure classification test
The elimination of unfair discrimination and cultural bias of any kind, is a contentious workplace issue in contemporary South Africa. To ensure fairness in testing, psychometric instruments are subjected to empirical investigations for the detection of ...

Evaluating the Magnitude of Differential Item Functioning in Polytomous Items [PDF]
Several recent studies have investigated the application of statistical inference procedures to the analysis of differential item functioning (DIF) in polytomous test items that are scored on an ordinal scale. Mantel’s extension of the Mantel-Haenszel test is one of several hypothesis-testing methods for this purpose.

O funcionamento diferencial dos itens Differential item functioning
A dificuldade de um item deveria ser uma propriedade independentemente de uma população em particular, da mesma forma que a habilidade de uma pessoa deveria ser uma característica sem referência a qualquer conjunto particular de itens.

An Analysis of Differential Bundle Functioning in Multidimensional Tests Using the SIBTEST Procedure
This study aims to analyze the differential bundle functioning in multi-dimensional tests with a specific purpose to detect this effect through differentiating the location of the item with DIF in the test, the correlation between the dimensions, the ...

Real and Artificial Differential Item Functioning in Polytomous Items [PDF]
Differential item functioning (DIF) for an item between two groups is present if, for the same person location on a variable, persons from different groups have different expected values for their responses. Applying only to dichotomously scored items in the popular Mantel–Haenszel (MH) method for detecting DIF in which persons are classified by their ...

Multilevel Generalized Mantel-Haenszel for Differential Item Functioning Detection
Research has demonstrated that when data are collected in a multilevel framework, standard single level differential item functioning (DIF) analyses can yield incorrect results, particularly inflated Type I error rates.

A new method for detecting differential item functioning in the Rasch model [PDF]
Differential item functioning (DIF) can lead to an unfair advantage or disadvantage for certain subgroups in educational and psychological testing. Therefore, a variety of statistical methods has been suggested for detecting DIF in the Rasch model.
