The Developmental Neuropsychological Assessment (NEPSY; Korkman, Kirk, & Kemp, 1998) was used to assess neuropsychological functioning in five domains: Attention/Executive functioning, Language, Visuospatial, Sensorimotor, and Memory. The NEPSY was used as a measure of neuropsychological functioning because at the time this study was initiated, it was the only broad-based standardized test battery of neuropsychological functioning that would allow for continuity of measurement between preschool and school-age. In addition, it provides age- and gender-specific norms that enable comparison to other samples of children. Test-retest reliability for the domains ranged from .70 to .91 (Korkman et al., 1998). In the present sample, Cronbach’s alphas of the five domains at BL, F1, F2, and F3 were .72, .78, .75, and .73, respectively.
