A 1982 study by Kellerman, and his associates, reported in this Journal, attempted to replicate a 1981 study be Stehbens, also published in this Journal. The Stehbens paper reported results from intelectual evaluations of pediatric cancer patients completed shortly after diagnosis at the University of Iowa, Kellerman's study failed to find an increased incidence of significant (15 points or more) discrepancies between Verbal and Performance IQ measures. Kellerman then criticizes the Stehbens paper on several methodological grounds. This reply defends the Stehbens paper by refuting Kellerman's criticisms, and concludes that both studies are consistent in finding lower Verbal than Performance IQ scores in newly diagnosed children with acute lymphoblastic leukemia, and that the difference amounts to approximately 8 to 10 IQ points in both studies.
