Dombrowski, Stefan C.; Beaujean, A. Alexander; McGill, Ryan J.; Benson, Nicholas F. – Journal of Psychoeducational Assessment, 2019
The Woodcock-Johnson Tests of Achievement, Fourth Edition (WJ IV ACH) is purported to align with Cattell-Horn-Carroll (CHC) theory and offers upward of 20 scores within its interpretive and scoring system. The Technical Manual does not furnish validity evidence for the scores reported by the scoring system, suggesting that evidentiary support may…

Benson, Nicholas F.; Beaujean, A. Alexander; Donohue, Ashley; Ward, Emily – Journal of Psychoeducational Assessment, 2018
W scores are used in a number of commercially available tests. Due to their complex nature, it can be hard for applied researchers and practitioners to understand them or even acquire information about them beyond what is provided in technical manuals. In this article, we provide information regarding the background and derivation of W scores that…

Beaujean, A. Alexander – Journal of Psychoeducational Assessment, 2018
Simulation studies use computer-generated data to examine questions of interest that have traditionally been used to study properties of statistics and estimating algorithms. With the recent advent of powerful processing capabilities in affordable computers along with readily usable software, it is now feasible to use a simulation study to aid in…

Parkin, Jason R.; Beaujean, A. Alexander; Firmin, Michael W.; Qiu, Xiao; Firmin, Ruth L. – Journal of Psychoeducational Assessment, 2018
In this study, we examined the factor structure, reliability, and external validity of scores from the Comprehensive Test of Nonverbal Intelligence-Second Edition (CTONI-2) using an independent sample of young adults currently enrolled in a postsecondary institution. Although the subtests appear to be measuring general intelligence, the aggregate…

Beaujean, A. Alexander; Hull, Darrell M.; Sheng, Yanyan; Worrell, Frank C.; Bolen, Judy; Verdisco, Aimee E. – Journal of Psychoeducational Assessment, 2017
We examined the structure of the new "Block Patterns" (BP) test from the Shipley Institute of Living Scale-Second Edition in a sample of Jamaican young adults. To date, very little has been published on the properties of this subtest's items and scores. The BP test is similar in design to the Block Design subtest found in many cognitive…

Beaujean, A. Alexander – Journal of Psychoeducational Assessment, 2016
One of the ways to increase the reproducibility of research is for authors to provide a sufficient description of the data analytic procedures so that others can replicate the results. The publishers of the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V) do not follow these guidelines when reporting their confirmatory factor…

Richerson, Lindsay P.; Watkins, Marley W.; Beaujean, A. Alexander – Journal of Psychoeducational Assessment, 2014
Measurement invariance of the Wechsler Intelligence Scale for Children--Fourth Edition (WISC-IV) was investigated with a group of 352 students eligible for psychoeducational evaluations tested, on average, 2.8 years apart. Configural, metric, and scalar invariance were found. However, the error variance of the Coding subtest was not constant…
