Methodology for making cross-national comparisons is an area of increasing interest in social and public health related research. When studying socio-economic differences in health outcomes cross-nationally, there are several methodological issues of concern, especially when data is derived from self-reported questionnaires. Health Behaviour in…

This article argues that given its structural conditions, development aid bears a particularly heavy burden of learning and accountability. Unfortunately, however, the organization of evaluation guarantees that evaluations will be inconsistent and it creates incentives for positive bias. This article presents evidence from organizational studies…

A reply to an article by Hunter and Schmidt criticizing the author's earlier work on test bias. (MP)

The article argues with Darlington's assertion that the rational approach can reconcile differing viewpoints. (MP)

This article applies the Breslow-Day test of trend in odds ratio heterogeneity (BD) to the detection of nonuniform DIF. A simulation study was conducted to assess the power and Type I error rate of BD, as well as a combined decision rule (CDR), whereby a decision of the existence of DIF was based on a combination of the decisions made using BD and…

The purpose of the present study is to examine the language characteristics of a few states' large-scale assessments of mathematics and science and investigate whether the language demands of the items are associated with the degree of differential item functioning (DIF) for English language learner (ELL) students. A total of 542 items from 11…

Two unresolved implementation issues with logistic regression (LR) for differential item functioning (DIF) detection include ability purification and effect size use. Purification is suggested to control inaccuracies in DIF detection as a result of DIF items in the ability estimate. Additionally, effect size use may be beneficial in controlling…

This study examines the differential item functioning (DIF) of the English version and the Japanese-translated version of the Multiple Affect Adjective Check List--Revised (MAACL-R) using the logistic regression (LR) procedure. The results of the LR are supplemented by multiple group confirmatory factor analysis (MGCFA). A total of five items are…

Asa Hilliard has left his mark, and his name belongs in the pantheon of esteemed African American scholars, educational researchers, teachers, and activists. Although his work has served as a clarion call for an Afrocentric orientation in psychology and education to address the needs of African American students, his contributions to the field's…

Phrenologists believed that specific brain regions corresponded to certain character traits. In addition, the size of each brain region was believed to determine the strength of the respective trait. Phrenology originated in Austria with Franz Josef Gall and was popularized and commercialized in America at the end of the 19th century by Orson…

As part of the ongoing education reform initiated by the Hong Kong Education Bureau (EDB), Liberal Studies will become a compulsory subject in senior secondary schools in 2009. It will be one of the core subjects all students must take, besides English, Chinese and Mathematics. Some of the objectives of the subject include cultivating critical…

Sources of test bias are discussed and steps to prevent or reduce bias in tests are listed. Test bias can occur because of the way test materials are written, the conditions of administration, and the interpretations given the results. Steps to prevent or reduce bias arising in the test development process include: (1) using heterogeneous sets of…

Previous arguments against the use of Analysis of Variance (ANOVA) to determine test bias are extended. Explains why ANOVA may obscure test bias when it exists and also create a false impression of bias when it does not exist. (RB)

Investigated racial differences in the Minnesota Multiphasic Personality Inventory by comparing samples of Black and White men charged with murder (N=160). Results indicated Black murderers tend to deny symptoms of pathology and are more socially outgoing. The confounding effects of intelligence suggested separate Black and White norms are…
