The Stanford-Binet, Fourth Edition: a small study of concurrent validity

To date most studies of construct and concurrent validity of the Stanford-Binet Intelligence Scale, Fourth Edition, have employed an established measure of ability as the criterion. Here achievement, assessed by the Wide Range Achievement Test-Revised and the Peabody Individual Achievement Test, was the criterion for establishing concurrent validity. The sample consisted of a naturally occurring group of 21 children referred for learning difficulties. The results provided partial support for the theoretical model of the Stanford-Binet IV. Intercorrelations among individual Stanford-Binet IV and achievement subtest scores were examined to generate explanatory hypotheses for those predictions which were not empirically supported. Finally, correlations between the WISC-R and the achievement measures were compared with those between the Stanford-Binet IV and the achievement measures. Examination shows that the correlations of the Stanford-Binet IV with achievement are as strong as and sometimes stronger than those between the WISC-R and achievement.
