The Effects Of Differential Item Functioning On Predictive Bias
… the relation between measurement bias at the item level (differential item functioning, dif) and predictive bias at the test score level. Dif was defined as a difference in the probability of getting a test item correct for examinees with the same ability but from different subgroups. …

Differential item functioning on the Myers-Briggs type indicator
Differential item functioning on the Myers-Briggs Type Indicator (MBTI) was examined in regard to gender. The Myers-Briggs has a differential scoring system for males and females on its thinking/feeling subscale. This scoring system preserves the 60 % thinking male and 30 % thinking female …

Differential Item Functioning Analysis of the Herrmann Brain Dominance Instrument
Differential item functioning (DIF) is present when examinees who have the same level of a trait have a different probability of correctly answering a test item intended to measure that trait (Shepard & Averill, 1981). The following study is a DIF analysis of the Herrmann Brain Dominance Instrument …

Differential Item Functioning on the Armed Services Vocational Aptitude Battery
Utilizing Item Response Theory (IRT) methodologies, the Armed Services Vocational Aptitude Battery (ASVAB) was examined for differential item functioning (DIF) on the basis of crossed gender and ethnicity variables. Both the Mantel-Haenszel procedure and an IRT area-based technique were utilized to …

Differential Item Functioning Analysis of Physical Activity Disparities in the U.S
… PA disparities. However, it is unknown if the items used in these questionnaires are biased against a subgroup in the population. It is also not clear to what degree the disparities in PA are affected by the biased items if there are any. In addition, the elimination of PA disparities should …

Differential Item Functioning on the International Personality Item Pool's Neuroticism Scale
… of the public-domain International Personality Item Pool (IPIP) scales has grown significantly over the past decade (Goldberg, Johnson, Eber, Hogan, Ashton, Cloninger, & Gough, 2006) research on the psychometric properties of the items and scales have become increasingly important. This research …

Investigating Stereotype Threat as a Source of Black/White Differential Item Functioning
… stereotype threat is a potential source of differential item functioning (DIF). Additionally, this study examines cognitive engagement and emotionality patterns on mathematics achievement tests. An experiment designed to investigate the impact of stereotype threat on test performance when …

Using differential item functioning analysis to determine differential interpretations of survey questions
The application of Differential Item Functioning (DIF) analysis to noncognitive areas such as psychological and attitudinal measurement is a natural extension of the current research and is the focus of this study. This study uses DIF analyses to examine differential item functioning of Likert …

A Differential Item Functioning Analysis of The New Mexico English Language Proficiency Assessment
… step is overlooked, the assessment may include items that unfairly position one group of home language scores over another group. An omission of home languages was the case for the New Mexico English Language Proficiency Assessment (NMELPA) (Harcourt Assessment, Inc., 2006, 2007). For this …

Gender and Ethnicity-Based Differential Item Functioning on the Myers-Briggs Type Indicator
Item Response Theory (IRT) methodologies were employed in order to examine the Myers-Briggs Type Indicator (MBTI) for differential item functioning (DIF) on the basis of crossed gender and ethnicity variables. White males were the reference group, and the focal groups were: black females, black …

HIGH-STAKES TESTS FOR STUDENTS WITH SPECIFIC LEARNING DISABILITIES: DISABILITY-BASED DIFFERENTIAL ITEM FUNCTIONING
… this study was to investigate disability-based differential item functioning (DIF) on a statewide high-stakes mathematics test administered in the Spring of 2003 to all students seeking a high-school diploma in one state in the eastern part of the U.S. Overall performance scores for all students …

Differential Item Functioning and Opportunity to Learn: Adjusting the Mantel-Haenszel Chi-Square Procedure
… not being treated exactly like everyone else. Differential item functioning (DIF) refers to a test item that does not perform the same way for two groups of examinees after controlling for ability.

An Examination of the Improved Wald Test for Differential Item Functioning Detection with Multiple Groups
Methods for identifying items that function differentially (DIF) across groups have over time become increasingly essential for establishing validity in psychometric testing. There is a vital need for simultaneously comparing multiple groups, evidenced by the widespread proliferation of …

Selecting an Optimal Measurement Model and Detecting Differential Item Functioning Using Bayesian Confirmatory Factor Analysis
… constrained parameter estimates in detecting differential item functioning (DIF). I assessed the relative efficiency of WAIC compared to DIC, evaluated analytical WAIC SEs by calculating relative bias, and reported how often WAIC and DIC indicated a preference for each invariance model. I …

Using Differential Item Functioning (Dif) Procedures for Investigating the Cross -Cultural Equivalence of Personality Tests
… it had the same number of factors and the same items on each factor. According to the DIF results, the choice of matching variables based on a combination of internal and external measures appeared to have little effect and the iterative purification method was unsuccessful. The DIF results were …

Methods of Detecting Differential Item Functioning: A Comparison of Item Response Theory and Confirmatory Factor Analysis
<p>Differential item functioning (DIF) occurs when an item performs statistically differently for a reference group than for a focal group. DIF is a threat to the validity of a test, and it can lead to illegal usage of a test in situations such as employee selection. Thus, DIF has important …
