Exploring differential item functioning in the SF-36 by demographic, clinical, psychological and social factors in an osteoarthritis population [PDF]
The SF-36 is a very commonly used generic measure of health outcome in osteoarthritis (OA). An important, but frequently overlooked, aspect of validating health outcome measures is to establish if items work in the same way across subgroup of a ...

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.

Detecting Differential Item and Step Functioning with Rating Scale and Partial Credit Trees [PDF]
Several statistical procedures have been suggested for detecting differential item functioning (DIF) and differential step functioning (DSF) in polytomous items.

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.

A Penalty Approach to Differential Item Functioning in Rasch Models [PDF]
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 ...

Does multidimensionality cause DIF? [PDF]
The differential item functioning (DIF) of an item that initially assumed unidimensional is frequently attributed to the assumption of multidimensionality.

Many Prolog programs are unnecessarily impure because of inadequate means to express syntactic inequality. While the frequently provided built-in `dif/2` is able to correctly describe expected answers, its direct use in programs often leads to overly complex and inefficient definitions --- mainly due to the lack of adequate indexing mechanisms.

Developments in Defining dif [PDF]
The Gram-negative soil bacterium Myxococcus xanthus has a complex life cycle that involves vegetative growth and, when nutrients are limiting, formation of spore-containing fruiting bodies. The progression of the developmental cycle depends in part upon the ability of M.
