A psychometric examination of the knowledge of ADHD scale

Saskatchewan-based pre-service and in-service teachers knowledge of ADHD was assessed and data was collected to accumulate psychometric evidence for the modified K-ADHD (Jerome, Gordon, & Hustler, 1994) scale. Using results from a questionnaire administered to pre-service (n = 100) and in-service (n = 66) teachers, the current study did find a significant difference on the K-ADHD (Jerome et al., 1994) scale between groups. Divergent and convergent validity evidence was found for the K-ADHD (Jerome et al., 1994) for both groups. However, reliability estimates were questionable between in-service (á = .66) and pre-service (á = .82) teachers, possibly due to asymmetric outlier contamination. The evidence found for the K-ADHD (Jerome et al., 1994) scale suggests problems with the psychometrics of the instrument. Future implications and research are discussed.
