Applied Psychological Measurement, 2009
Douglas, Roussos, and Stout introduced the concept of differential bundle functioning (DBF) for identifying the underlying causes of differential item functioning (DIF). In this study, reference group was simulated to have higher mean ability than the focal group on a nuisance dimension, resulting in DIF for each of the multidimensional items that ...

A Synthesis of the Peer‐Reviewed Differential Bundle Functioning Research
Educational Measurement: Issues and Practice, 2013The purpose of this article was to present a synthesis of the peer‐reviewed differential bundle functioning (DBF) research that has been conducted to date. A total of 16 studies were synthesized according to the following characteristics: tests used and learner groups, organizing principles used for developing bundles, DBF detection methods used, and ...

Increasingly, tests are being translated and adapted into different languages. Differential item functioning (DIF) analyses are often used to identify non‐equivalent items across language groups. However, few studies have focused on understanding why some translated items produce DIF.

International Journal of Testing, 2012
Understanding adolescent self-concept is of great concern for educators, mental health professionals, and parents, as research consistently demonstrates that low self-concept is related to a number of problem behaviors and poor outcomes. Thus, accurate measurements of self-concept are key, and the validity of such measurements, including the popular ...

Journal of Educational Measurement, 1996
This article proposes two multidimensional IRT model‐based methods of selecting item bundles (clusters of not necessarily adjacent items chosen according to some organizational principle) suspected of displaying DIF amplification. The approach embodied in these two methods is inspired by Shealy and Stout's (1993a, 1993b) multidimensional model for DIF.

Current Alzheimer Research, 2015
Previous studies have demonstrated that Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI) exhibited anatomical and functional abnormalities in the anterior cingulate cortex (ACC) and accumulating evidence supported the hypothesis that changes in the ACC predict the progression from aMCI to AD. In this study, we aimed to explore how

Educational Measurement: Issues and Practice, 2001
What is differential bundle functioning and how is this different from differential item functioning? Can test specifications be used to identify and aid in the interpretation of differential bundle functioning? How can differential bundle functioning lead to an improved understanding of why groups perform differently on achievement tests?

The Impact of Multidimensionality on the Detection of Differential Bundle Functioning Using SIBTEST.
2008In response to public concern over fairness in testing, conducting a differential item functioning (DIF) analysis is now standard practice for many large-scale testing programs (e.g., Scholastic Aptitude Test, intelligence tests, licensing exams). As highlighted by the Standards for Educational and Psychological Testing manual, the legal and ethical ...
