Epub 2022 Nov 13. Archives of clinical neuropsychology : the official journal of the National Academy of Neuropsychologists, The discriminant validity of the Upper Preschool Level of the Differential Ability Scales (DAS) was studied using 32 at-risk preschoolers (females = 14, males = 18) with a mean age of 57.28 months, The Differential Ability Scales (DAS; Elliott, 1990c) is a comprehensive battery of cognitive and achievement tests that are designed for children and adolescents between the ages of 2 1/2 and 17. Regression line reflects age (in months; centered at grand mean of 63.67) entered as a covariate for Verbal; age not significant in Nonverbal equation. Individually administered intelligence measures are commonly used in diagnostic work, but there is a continuing need for research investigating possible test bias among these measures. Method of Administration: Individually administered, norm-referenced measure of cognitive abilities; aligned to the Cattell-Horn-Carroll (CHC) model two overlapping batteries: Early Years (2:6-6:11) and School-Aged (7:0-17:11) The scores help in deciding how Useful features and differences in the administration strategy of DAS are reviewed. 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. Front Psychol. Excellent standardization. (For well-normed tests intended for children in the United States, this means that the group of children used to norm the assessment was matched to the U.S. census proportions in terms of Differential Ability Scales.

These cluster scores consist of six core subtests (or four, for children 2:6-3:5) that are designed to measure verbal, nonverbal, and spatial reasoning. Concerns about the ability-achievement discrepancy method for specific learning disability (SLD) determination led to alternative research-based methods, such as failure to respond to intervention.

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. However, NVIQ was generally stable for the majority of individuals with ASD whose cognitive ability was in the average range. It provides specific information about several areas of a childs cognitive abilities, including verbal skills, nonverbal problem-solving, and spatial awareness. A historical, Over a decade ago, Pasamanick and Knobloch (1958) demonstrated that disadvantaged populations manifest severe visual perceptual deficits. Unauthorized use of these marks is strictly prohibited. S. Elliott. Autistic symptomatology was not associated with cognitive scores, while adaptive behavior was positively associated. 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.
