This meta-analysis examined the validity of an alternative to traditional assessments called the Wonderlic which is a brief measure of general mental ability. Our results showed significant, positive correlations between Wonderlic scores and academic performance in general ([r-bar] = 0.26), between Wonderlic scores and undergraduate GPA in…

The present research compares the operation of situational judgement and biodata measures between Chinese and U.S. respondents. We describe the development and past research on both measures, followed by hypothesized differences across the two groups of respondents. We base hypotheses on the nature of the Chinese and U.S. educational systems and…

Many medical schools have adopted multiple mini-interviews (MMI) as an advanced selection tool. MMIs are expensive and used to test only a few dozen candidates per day, making it infeasible to develop a different test version for each test administration. Therefore, some items are reused both within and across years. This study investigated the…

Given the prevalence of low-stakes testing internationally (e.g., NAEP, TIMSS, PIRLS), it is crucial to try to better understand examinee motivation in these contexts. In the current study, mixture modeling results supported three different profiles of test-taking effort over the course of five tests. Classes 1 and 2 had varying levels of effort…

When power tests include a time limit, it is important to assess the possibility of speededness for examinees. Past research on differential speededness has examined gender and ethnic subgroups in the United States on paper and pencil tests. When considering the needs of a global audience, research regarding different native language speakers is…

We present an extension of the logistic regression procedure to identify dichotomous differential item functioning (DIF) in the presence of more than two groups of respondents. Starting from the usual framework of a single focal group, we propose a general approach to estimate the item response functions in each group and to test for the presence…

The equal ability distribution assumption associated with the equivalent groups equating design was investigated in the context of a selection test for admission to higher education. The purpose was to assess the consequences for the test-takers in terms of receiving improperly high or low scores compared to their peers, and to find strong…

A critical assumption in cross-cultural comparative research is that the instrument measures the same construct(s) in exactly the same way across all groups (i.e., the instrument is measurement and structurally equivalent). Structural equation modeling (SEM) procedures are commonly used in testing these assumptions of multigroup equivalence.…

The study of measurement models in psychometrics by means of dimensionality reduction techniques such as Principal Components Analysis (PCA) is a very common practice. In recent times, an upsurge of interest in the study of artificial neural networks apt to computing a principal component extraction has been observed. Despite this interest, the…
