DIFSIB: A SIBTEST Package [PDF]
The R package DIFSIB provides a direct translated version of the SIBTEST, Crossing- SIBTEST, and POLYSIBTEST procedures that were last updated and released in 2005. Having these functions directly written from Fortran into R code will allow researchers and practitioners to easily access the most recent versions of these procedures when they are ...

The Power of Crossing SIBTEST [PDF]
Crossing SIBTEST or CSIB is designed to detect crossing differential item functioning (DIF) as well as unidirectional DIF. A theoretical formula for the power of CSIB is derived based on the asymptotic distribution of the test statistic under the null and alternative hypotheses.

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 ...

Reevaluating the SIBTEST Classification Heuristics for Dichotomous Differential Item Functioning [PDF]
A simulation study was conducted to investigate the heuristics of the SIBTEST procedure and how it compares with ETS classification guidelines used with the Mantel–Haenszel procedure. Prior heuristics have been used for nearly 25 years, but they are based on a simulation study that was restricted due to computer limitations and that modeled item ...

Examination of Gender-Related Differential Item Functioning Through Poly-BW Indices [PDF]
The existing differential item functioning (DIF) detection approaches relying on item difficulty or item discrimination are limited for understanding the associates of DIF items, and consequently, DIF items were conventionally either deleted or ignored ...

DETECTING DIF FOR POLYTOMOUSLY SCORED ITEMS: AN ADAPTATION OF THE SIBTEST PROCEDURE [PDF]
ABSTRACTRecently, Shealy and Stout (1993) proposed a DIF detecting procedure SIBTEST, which is 1) IRT model based, 2) non‐parametric, 3) does not require IRF estimation, 4) provides a test of significance, and 5) estimates the amount of DIF. Current versions of SIBTEST can only be used for dichotomously scored items. However, in this paper an extension

Determination of differantial item functioning (DIF) according to SIBTEST, Lord’s χ2 , Raju’s area measurement and Breslow-Day methods [PDF]
The aim of this study is to examine whether the items in the mathematics subtest of the Centralized High School Entrance Placement Test [HSEPT] administered in 2012 by the Ministry of National Education in Turkey show DIF according to gender and type of ...

DEVELOPMENT OF A SIBTEST BUNDLE METHODOLOGY FOR IMPROVING TEST EQUITY, WITH APPLICATIONS FOR GRE TEST DEVELOPMENT [PDF]
ABSTRACTThe purpose of this study was to develop a differential‐item‐functioning (DIF)/impact methodology capable of accurately isolating underlying, conceptually‐based causes of DIF (differing item performances across examinee groups that are matched on ability) and impact (differing item performances across examinee groups that are not matched on ...

Differential Item Functioning: its Multidimensional Model and Resulting Sibtest Detection Procedure
A multidimensional model of differential item functioning (DIF) developed by Shealy and Stout is presented. It explains how individual items combine to produce differential test functioning (DTF) at the test level. Recent developments based on this approach, including development of the DIF/DTF detection procedure SIBTEST, are surveyed.
