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. The NEPSY-II is a comprehensive, standardized neuropsychological assessment tool used to evaluate several domains of cognitive abilities. It can be administered to children aged 3 years to 16 years and 11 months and provides norm-based scores in the areas of executive functioning (mental skills are used to complete tasks), attention, language, memory, learning, sensorimotor abilities, visual-spatial processing (mentally moving objects around), and social perception (forming impressions of and make inferences about others). However, curve estimation revealed large mean differences in scores that varied as a function of the child's cognitive ability level. This study was an effort to subtype adolescents' learning disabilities using scores on the Woodcock-Johnson Psycho-Educational BatteryRevised to characterize subtypes, suggesting that these students had two specific types of learning disorders. The purpose of this study was to determine whether distinct subgroups of children with learning disabilities could be identified using a single, recently developed instrumentthe Differential Ability Scales (DAS). We 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 full spectrum of cognitive ability.

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. 4.

The Differential Ability Scales, Second Edition (DAS-II; Elliott 2007) is an individually administered test designed to measure distinct cognitive abilities for children and adolescents ages 2 years, 6 months to 17 years, 11 months. The DAT was first published in 1947 and has multiple forms and levels. WebIntellectual ability tests measure the abilities of an individual child relative to the abilities of children in the general population. One current intelligence measure, the Differential Ability Scales, Second Edition (DAS-II), is a test with growing popularity. -Marit Korkman, PhD, Ursula Kirk, PhD, and Sally Kemp, PhD. Notably, the core battery for ages 2:6-3:5 contains only four subtests and may be more useful as a screening instrument for children of this age.

Roid, Lucy J. Miller, Mark Pomplun, and Chris Koch. This test provides an overall measure of cognitive abilities, referred to as a Full Scale Battery. This measure allows a comparison of language development even in a child who is one to two years old. Useful features and differences in the administration strategy of DAS are reviewed. WebThis cognitive assessment tool can be administered to children from aged 2 years and 6 months to 6 years and 11 months in the Lower Battery and an Upper Batter that can be Front Psychol. Scores on the DAS-II and MSEL were highly correlated, suggesting that they measure a similar construct. In addition to an overall composite , the General Conceptual Ability (GCA) score, this instrument also yields a Special Nonverbal Composite (SNC) score for children who may have difficulty with oral language. This is individually adiministered measure of cognitive ability for those aged 6 to 16 years. Subjects. We conclude that interchanging MSEL and DAS-II scores 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.

The difference between overall scores is suggested to be attributable to a relative weakness in processing speed, which is assessed on the WISC-IV but not the DAS-II.
