| Abstract: | The 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 types of bundles that indicated statistically significant DBF in the hypothesized direction on multiple occasions. The article concludes with a list of suggestions to individuals who conduct DBF research. For example, effect size guidelines should be established for interpreting the amount of DBF in bundles of items assessed with simultaneous item bias test (SIBTEST), given that it is the most commonly used DBF procedure. This would reduce our reliance on statistical significance testing. General effect size guidelines are needed as well as guidelines for special circumstances like small sample cases. Other useful suggestions are offered as well. [ABSTRACT FROM AUTHOR] |
