Illustrating the Use of Nonparametric Regression to Assess Differential Item and Bundle Functioning Among Multiple Groups

, 2001
The purpose of this article is to illustrate the use of nonparametric regression with kernel smoothing (Ramsay, 1991), as implemented with the computer program TESTGRAF (Ramsay, 2000), to investigate differential item or bundle functioning among multiple

The MIMIC Model as a Tool for Differential Bundle Functioning Detection

, 2012
Increasingly, researchers interested in identifying potentially biased test items are encouraged to use a confirmatory, rather than exploratory, approach.

Differential Bundle Functioning Analysis of the Self-Description Questionnaire Self-Concept Scale for Kenyan Female and Male Students Using the MIMIC Model

, 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.

Exploration of the Validity of Gender Differences in Mathematics Assessment Using Differential Bundle Functioning

, 2011
The aims of this study are (a) to examine the sources of differential functioning by gender via differential bundle functioning (DBF) in mathematics assessment and (b) to use DBF to explore whether the differential functioning displayed is construct ...

Illustrating the Utility of Differential Bundle Functioning Analyses To Identify and Interpret Group Differences on Achievement Tests.

, 2005
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?

The Impact of Multidimensionality on the Detection of Differential Bundle Functioning Using Simultaneous Item Bias Test

, 2009
Douglas, Roussos, and Stout introduced the concept of differential bundle functioning (DBF) for identifying the underlying causes of differential item functioning (DIF).

Differential Bundle Functioning Using the DFIT Framework: Procedures for Identifying Possible Sources of Differential Functioning

, 1998
A general framework for assessing differential functioning of items and tests (DFIT) was recently proposed. Both unidimensional and multidimensional tests with either dichotomous or polytomous scoring can be handled within this framework.

Determination of Differential Bundle Functioning (DBF) of Numeracy and Literacy Tests Administered to Grade 3 Learners in South Africa

, 2010
The study is based on data gathered for the Assessment Modelling Initiative (AMI), part of the District Development Support Programme (DDSP) project conducted by the Human Sciences Research Council (HSRC) in 2002, in conjunction with the Department of ...

Identifying Possible Sources of Differential Functioning Using Differential Bundle Functioning With Polytomously Scored Data

, 2007
Oshima, Raju, Flowers, and Slinde (1998) described procedures for identifying sources of differential functioning for dichotomous data using differential bundle functioning (DBF) derived from the differential functioning of items and test (DFIT ...

Identifying Sources of Differential Item and Bundle Functioning on Translated Achievement Tests: A Confirmatory Analysis

, 2001
Increasingly, tests are being translated and adapted into different languages. Differential item functioning (DIF) analyses are often used to identify nonequivalent items across language groups. However, few studies have focused on understanding why some
