Recent advances in analysis of differential item functioning in health research using the Rasch model
BACKGROUND Rasch analysis with a focus on Differential Item Functioning (DIF) is increasingly used for examination of psychometric properties of health outcome measures. To take account of DIF in order to retain precision of measurement, split of DIF-items into separate sample specific items has become a frequently used technique. The purpose of the paper is to present and summarise recent adva...
متن کاملRasch Trees: A New Method for Detecting Differential Item Functioning in the Rasch Model.
A variety of statistical methods have been suggested for detecting differential item functioning (DIF) in the Rasch model. Most of these methods are designed for the comparison of pre-specified focal and reference groups, such as males and females. Latent class approaches, on the other hand, allow the detection of previously unknown groups exhibiting DIF. However, this approach provides no stra...
متن کاملA penalty approach to differential item functioning in Rasch models.
A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the membership to a subpopulation. We propose an explicit model for differential item functioning that includes a set of variables, containing metric as wel...
متن کاملUsing the raschtree function for detecting differential item functioning in the Rasch model
The psychotree package contains the function raschtree, that can be used to detect differential item functioning (DIF) in the Rasch model. The DIF detection method implemented in raschtree is based on the model-based recursive partitioning framework of Zeileis, Hothorn, and Hornik (2008) and employs generalized M-fluctuation tests (Zeileis and Hornik 2007) for detecting differences in the item ...
متن کاملA New Method for Detecting Differential Item Functioning in the Rasch Model
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. Most of these methods are designed for the comparison of pre-specified focal and reference groups, such as males and females. Latent class approache...
