Concurrent validity of the WISC-IV and DAS-II in children with autism spectrum disorder. WebDifferential Ability Scales (DAS-II) The Differential Ability Scales (DAS-II) were developed as an evaluation tool for the cognitive ability and achievement of children. Composites combine to form a Full Scale Intelligence Quotient (FSIQ) which is an overall measure of intellectual ability. Colin Elliott and the other developers of the DAS used the most current statistical procedures in an attempt to create a test that is psychometrically sound. WebWe evaluated the correspondence of contemporaneous MSEL and the DAS-II scores in a mixed sample of children aged 2-10 years with autism spectrum disorder (ASD), non-ASD developmental delays, and typically developing children across the An open-label study evaluating the safety, behavioral, and electrophysiological outcomes of low-dose ketamine in children with ADNP syndrome.
