Abstract
The purpose of this study was to examine adaptive behaviour profiles in children with autism and moderate to severe developmental delay. Previous research has found that children with autism present a characteristic pattern of adaptive behaviour, as measured by the Vineland Adaptive Behavior Scales (VABS) (deficit in the domain of socialization, relative deficit in the domain of communication and relative strength in the domain of daily living). In this study VABS were administered (as part of a comprehensive evaluation of abilities) to a sample of 50 children with moderate to severe developmental delay (23 children with autism and 27 chronological and developmental age matched non-autistic children). Contrary to initial predictions, the sample presented fairly homogeneous adaptive behaviour profiles. Results are discussed with respect to the effectiveness of adaptive behaviour profiles in the detection of autism and the importance of employing limited chronological and developmental age ranges in the study of autism in infancy.
