Abstract

Attention Deficit Hyperactivity Disorder (ADHD) can be assessed using variety of measures including clinical interviews, behavioural observations, respondent checklists, cognitive ability scores, and/or computerized performance tests. The use of cognitive ability tests to help diagnose ADHD has recently gained popularity (Frazier, et al., 2004); the Woodcock-Johnson III Tests of Cognitive Abilities and Tests of Achievement (WJ III) is one such test. However, research on the relationship between the WJ III and ADHD is speculative. The present investigation sought to determine whether the WJ III has an attention factor by factor analyzing WJ III scores and an ADHD measure, the IVA+Plus«. The software application could not converge on a proper solution for the IVA data, thus, the analyses were modified to correlation and regression. Mild support was found for past research on the relationship between the WJ III and ADHD. Although the statistical results of the current investigation were unremarkable, several key areas of research in need of further study were illuminated - the most important of which detected a potential major flaw in a popular commercially-sold ADHD measure.
