Stability of the SB:FE and K-ABC for Young Children From Low-Income Families:: A 5-Year Longitudinal Study

Abstract

The stability of the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE) and the Kaufman Assessment Battery for Children (K-ABC) was investigated by testing a sample of 65 African American and White children from low socioeconomic status (SES) families. Both tests were administered at ages 4, 6, and 9. Data were analyzed by comparing mean scores, computing correlation coefficients, and determining individual change scores among the 3 test times. In general, both tests were found to be quite stable during the 5-year period. Mean scores for the group were roughly equivalent, correlation coefficients were high, and change scores for the majority of the children were small. Racial differences were negligible.
