The Vineland Social Maturity Scale, the Peabody Picture Vocabulary Test (PPVT), the Adaptive Behavior Scale (ABS), and the Behavior Development Survey, an abbreviated five-domain version of the ABS, were administered to a stratified random sample of 111 mentally retarded individuals. The network of correlations obtained among these measures indicated that the Behavior Development Survey is a concurrently valid method of assessing adaptive behavior and demonstrates a pattern of correlations with the Vineland and the PPVT similar to that demonstrated by the more extensive ABS.
