A bibliometric study of differential item functioning
Scientometrics, 2005This study presents a bibliometric analysis of scientific output in the area of Differential Item Functioning (DIF), the aim being to offer an overview of research activity in this field and characterise its most important aspects and their evolution over the last quarter of the 20th century, thus providing data regarding the basis on which this ...

Investigating Item Bias in a CS1 Exam with Differential Item Functioning
Proceedings of the 52nd ACM Technical Symposium on Computer Science Education, 2021Reliable and valid exams are a crucial part of both sound research design and trustworthy assessment of student knowledge. Assessing and addressing item bias is a crucial step in building a validity argument for any assessment instrument. Despite calls for valid assessment tools in CS, item bias is rarely investigated.

International Journal of Testing, 2015
Raju, van der Linden, and Fleer (1995) introduced a framework for differential functioning of items and tests (DFIT) for unidimensional dichotomous models. Since then, DFIT has been shown to be a quite versatile framework as it can handle polytomous as well as multidimensional models both at the item and test levels.

A Statistical Test for Differential Item Pair Functioning
Psychometrika, 2015This paper presents an IRT-based statistical test for differential item functioning (DIF). The test is developed for items conforming to the Rasch (Probabilistic models for some intelligence and attainment tests, The Danish Institute of Educational Research, Copenhagen, 1960) model but we will outline its extension to more complex IRT models.

Schizotypy, marijuana, and differential item functioning
Human Psychopharmacology: Clinical and Experimental, 2006AbstractAt least five studies report elevated schizotypy scores in cannabis users. The current research confirms higher schizotypy scores in regular cannabis users. Nevertheless, further analyses reveal that select items on the brief version of the Schizotypal Personality Questionnaire do not function comparably in current and former users.

Differential Item Functioning in Attitude Assessment
Evaluation Practice, 1997Differential item functioning (DIF) is not often seen in the literature on attitude assessment. A brief discussion of DIF and methods of implementation is followed by an illustrative example from a program evaluation, using an attitude-towards-science scale with 1550 children in grades one through six. An item exhibiting substantial DIF with respect to

5 Differential Item Functioning and Item Bias
2006Publisher Summary This chapter presents a description of many of the commonly employed methods in the detection of item bias. Because much of the statistical detection of item bias makes the use of differential item functioning (DIF) procedures, the majority of this chapter focuses on the description of statistical methods for the analysis of DIF ...

Screening Test Items for Differential Item Functioning
Journal of Educational and Behavioral Statistics, 2014A method for medical screening is adapted to differential item functioning (DIF). Its essential elements are explicit declarations of the level of DIF that is acceptable and of the loss function that quantifies the consequences of the two kinds of inappropriate classification of an item.
