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 ...

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 ...

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.

Investigating the existence of items with differential item functioning (DIF) may provide more accurate comparisons of group differences in studies that aim to compare scores obtained in a test by groups with different characteristics.

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.

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 ...

Anchor selection strategies for DIF analysis: Review, assessment, and new approaches [PDF]
Differential item functioning (DIF) indicates the violation of the invariance assumption for instance in models based on item response theory (IRT). For item-wise DIF analysis using IRT, a common metric for the item parameters of the groups that are to ...

Anchor methods for DIF detection: A comparison of the iterative forward, backward, constant and all-other anchor class [PDF]
In the analysis of differential item functioning (DIF) using item response theory (IRT), a common metric is necessary to compare item parameters between groups of test-takers.
