Item bias studies investigate whether different ethnic, racial or cultural groups show different response behaviour to test items. Reviews of item bias methods have been given by Jensen (1980, chap. 9), Petersen (1977), and Rudner, Getson and Knight (1980). A distinction will be made between unconditional and conditional methods.

Item Bias and Test Multidimensionality
1988In recent decades the question whether tests are equally “fair” for members of several (cultural) groups has received considerable attention. Often only the item responses of one single test measuring the construct of interest are available, which means the researcher does not have a criterion at his disposal by which the “fairness” of the total scores

The Journal of Experimental Education, 1985
AbstractThis brief note suggests a new method of measuring item bias. A test for item bias is also suggested that is based on standard asymptotic results.

Detecting Item BIAS in Affective Scales
Educational and Psychological Measurement, 1987The purpose of the study was to demonstrate the use of confirmatory factor analysis to investigate the existence of item bias in an affective scale measuring self-concept. The data were collected from three ethnic groups (Black, Hispanic, and White) in grade eight (N = 1264). The factor structure and item uniqueness were simultaneously compared across

Item Bias and Individual Differences
1991To date the study of item bias has been almost exclusively statistical and methodological. Bias is defined in terms of a statistical technique, the procedure is applied and items with deviant values are assumed to be biased. That is, largely unexamined assumptions are made about the probable effects of bias, if it exists, and procedures are then ...

Conceptual Implications of Item Bias
1991Any comparison presupposes a tertium comparationis, i.e. an invariant standard or measurement scale in terms of which the comparison can be made. In the natural sciences scale identity can be formally defined in terms of measurement procedures. In psychology where interactions occur between the measurement instruments and the objects of measurement ...

A Procedure to Detect Item Bias Present Simultaneously in Several Items
1991Abstract : This paper presents a statistical procedure (denoted by SIB) designed to test for undirectional test bias existing simultaneously in several items of an ability test. It was argued in Shealy and Stout (1991) that in order to model such bias with an IRT model, a multidimensional model is necessary.

Contingency Table Models for Assessing Item Bias
Journal of Educational Statistics, 1982Two strategies for assessing item bias are discussed: Methods based on Item x Group interaction and methods that compare the probabilities of a correct response for different groups conditional on ability level. In latent trait models, correct response probabilties are compared conditional on latent ability; in Scheuneman’s (1979) method these ...

Detecting Gender Bias Through Test Item Analysis
The Physics Teacher, 2009Many physical science and physics instructors might not be trained in pedagogically appropriate test construction methods. This could lead to test items that do not measure what they are intended to measure. A subgroup of these items might show bias against some groups of students.
