Stability of the Kaufman Assessment Battery for Children for a sample of Mexican-American children

Test-retest stability of the Kaufman Assessment Battery for Children (K-ABC) was investigated over a 5$\text{1}\text{2}$-month interval for 42 Mexican-American preschool/kindergarten children. The results indicated that the stability coefficients for K-ABC Global scales and subtests were generally of adequate magnitudes (e.g., .70s and .80s), providing some evidence that the K-ABC is a relatively stable instrument for the sample. The results are discussed in the context of a test-retest study reported in the K-ABC Manual. Global scale stability coefficients were found to range from .76 to .90, and for the subtests the coefficients ranged from .26 to .89. The patterns of gain scores were very similar to the patterns reported in the stability investigation in the K-ABC Manual.
