What Is the "g" That the K-ABC Measures?
Keith, Timothy Z.; Novak, Christine G.
The K-ABC purports to be a fresh alternative to standardized measures of intellectual functioning, by virtue of separating measurement of acquired factual knowledge from measurement of the ability to solve novel problems. Some researchers have questioned this claim to the capability of distinguishing aptitude and achievement. By analyzing the "g" factor underlying the K-ABC, the present study attempts to determine whether the "g" factor is best conceived as an achievement or intellectual ability factor. Hierarchical confirmatory factor analysis was used to compare the "g" factor underlying the K-ABC subtests with the "g" factor underlying the Wechsler Intelligence Scale for Children-Revised (WISC-R). Results indicate that the "g" factor from the subtests of both instruments can distinguish intelligence from achievement. Another interesting finding was that the WISC-R third factor, normally labeled Freedom from Distractibility or Memory, appeared to have a strong quantitative component. While these results do not refute the K-ABC model, they add to a growing body of evidence supporting an alternative interpretation of the achievement subtests as measures of verbal reasoning and general intelligence.
