Accounting for Intraindividual Profiles in the Wechsler Intelligence Scales Improves the Prediction of School Performance
IQ scores are often used to predict school performance. However, for children with learning disabilities, the predictive validity of IQ scores appears to be low. In the fourth and fifth versions of the Wechsler Intelligence Scales for Children (WISC), new ancillary indices were introduced. The General Ability Index ( GAI ) is a broad measure of fluid reasoning with verbal, visual-spatial, and figural test items. By contrast, the Cognitive Profici…
Improvement of Norm Score Quality via Regression-Based Continuous Norming
The interpretation of psychometric test results is usually based on norm scores. We compared semiparametric continuous norming (SPCN) with conventional norming methods by simulating results for test scales with different item numbers and difficulties via an item response theory approach. Subsequently, we modeled the norm scores based on random samples with varying sizes either with a conventional ranking procedure or SPCN. The norms were then cro…
Equivalence of Screen Versus Print Reading Comprehension Depends on Task Complexity and Proficiency
As reading and reading assessment become increasingly implemented on electronic devices, the question arises whether reading on screen is comparable with reading on paper. To examine potential differences, we studied reading processes on different proficiency and complexity levels. Specifically, we used data from the standardization sample of the German reading comprehension test ELFE II (n = 2,807), which assesses reading at word, sentence, and …
