AN ITERATIVE ITEM BIAS DETECTION METHOD
Journal of Educational Measurement, 1984Two 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 ...

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.

1983
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 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 ...

The Reliability of Six Item Bias Indices
Applied Psychological Measurement, 1984The reliabilities of six item bias indices were inves tigated for each of the eleven tests of the Iowa Tests of Basic Skills, using random samples of fifth-grade students. The reliability of an index was defined as its stability from one randomly equivalent group to an other. Both racial and sexual bias were considered.

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 ...

Reducing Item-Specific Nonresponse Bias
The Journal of Experimental Education, 1978This article describes a method of dealing with partially-responded-to questionnaires in survey research which utilizes nonparametric Bayesian discriminant analysis to predict missing responses based on “profiles” of the partial and the “complete” respondents. Some background of nonresponse bias in survey research is discussed, and two other methods of

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

A METHOD OF ASSESSING BIAS IN TEST ITEMS
Journal of Educational Measurement, 1979In the past few years, the issue of test bias with its far-reaching political and social implications has been the subject of much controversy. The majority of the research on bias has been concerned with the fair use of testing instruments in decision-making situations such as employment and college admissions. In general, the models employed in these

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).
