The DAS core subtests were found to be good measures of cognitive ability in children classified with ADHD and did not appear to be influenced by attention problems. The Differential Ability Scales (DAS) was created to provide practitioners with an alternative instrument that may be as effective as WISC-III in picking up specific patterns of learning difficulties. These are composed of 20 distinct subsets, which include 17 that are cognitive targets and 3 for achievement. WebThe Differential Ability Scales (2nd ed., DASII) is unique in that it goes beyond cognitive ability testing to give insight into how a child processes information. This reaction focuses on and, By clicking accept or continuing to use the site, you agree to the terms outlined in our. Would you like email updates of new search results? The authors concluded that interchanging MSEL and DAS-II scores in research studies without regard to the discrepancy in scores may produce misleading results in both cross-sectional and longitudinal studies of children with and without ASD, and, thus, this practice should be implemented with caution. Each composite index combines to form the Full Scale Intelligence Quotient which measures overall intellectual ability. A cluster analysis procedure was used to identify subgroups of children who manifested specific learning disabilities in reading (SLD/R) in terms of performance on a battery of eight language and perceptual tests, finding some significant differences in measures of oral reading and reading comprehension skills.
