Item bias and item response theory

International Journal of Educational Research, 1989
Abstract In this chapter the definition, detection, and explanation of item bias is discussed. Item bias is generally defined as conditional dependence; within the framework of item response theory the general definition implies that the item characteristic curves of two groups do not coincide.

AN ITERATIVE ITEM BIAS DETECTION METHOD

Journal of Educational Measurement, 1984
Two strategies for assessing item bias are discussed: methods that compare (transformed) item difficulties unconditional on ability level and methods that compare the probabilities of correct response conditional on ability level. In the present study, the logit model was used to compare the probabilities of correct response to an item by members of ...

5 Differential Item Functioning and Item Bias

2006
Publisher 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 ...

The Regression BIAS Method: A Unified Approach for Detecting Item BIAS and Selection BIAS

Educational and Psychological Measurement, 1985
Although several different procedures are available for detecting item bias and selection bias, there does not appear to be a single procedure for detecting both types of bias. It is proposed that the Regression Model, which is popular in selection bias research, be adopted for item bias detection, thereby providing a common framework for studying ...

Explaining Item Bias

1986
In this paper some methodological aspects of item bias research are discussed. First, the definitions of item bias are given; it is emphasised that the conditional definition, with related conditional item bias detection methods must be preferred. Second, the conditional definition is used for designing models for simulating item bias; the results of ...

EMPIRICAL COMPARISON OF SELECTED ITEM BIAS DETECTION PROCEDURES WITH BIAS MANIPULATION

Journal of Educational Measurement, 1984
Biased test items were intentionally imbedded within a set of test items, and the resulting instrument was administered to large samples of blacks and whites. Three popular item bias detection procedures were then applied to the data: (1) the three‐parameter item characteristic curve procedure, (2) the chi‐square method, and (3) the transformed item ...

Procedures for Extending Item Bias Detection Techniques to Polytomously Scored Items

Applied Measurement in Education, 1993
The recent increased emphasis on various types of performance assessments raises the question of what is the effect of such assessments on various population subgroups. This study was designed to suggest methodology for several statistical procedures to detect performance assessment items that function differently for two subgroups of examinees.

Effects of Item Wording on Sex Bias

Journal of Educational Measurement, 1989
This study examined the effects of gender‐related item‐wording changes on the performance of male and female examinees. Mathematics word problems and English language items were created in neuter, male, and female versions. Items were administered to randomly equivalent samples of about 300 high school juniors and seniors.

Simulation Studies of Item Bias Estimation Accuracy

2021
The item-parameter invariance assumption of Cognitive Diagnostic Models (CDMs) states that item parameters are not functionally dependent upon the characteristics of an examinee with respect to a specific examinee population. Violations of this assumption for a test item indicate the presence of item-bias for that item.
