Stability of the Stanford-Binet Fourth Edition and K-ABC for Young Black and White Children from low Income Families

Abstract

The stability of the Stanford-Binet: Fourth Edition and Kaufman Assessment Battery for Children was investigated by administering the tests to a sample of 71 low SES children at age 4 and again at age 6. Data were analyzed by comparing group mean scores, computing correlation coefficients, and determining individual change scores from time one to time two. The SB:FE mean composite scores for the group were very similar at both ages, correlation coefficients between the two sets of scores were high, and the difference scores were within acceptable limits. However, the area scores of the SB:FE were somewhat less stable. The correlation coefficients for the K-ABC Global scales were also high, but mean scores for this test increased significantly. Difference scores for the K-ABC scales also were within acceptable limits. Thus, both the SB:FE and K-ABC were highly stable from ages 4 to 6 for this sample of children from low income families. No significant differences were found between the Black and White subgroups, and the tests were found to be equally stable for both groups.
