The English or Spanish version of the caregiver interview form of the Vineland Adaptive Behavior Scales, Second Edition (Vineland II; Sparrow et al., 2005 ) was administered to measure child adaptive functioning skills. The Vineland II is a standardized test of adaptive functioning for individuals from birth to age 90 years. This parent report measure yields an adaptive behavior composite score and domain scores for communication, daily living, socialization, and motor development and has good test-retest reliability (.88-.92).
