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.

WebThe Differential Ability Scales Second Edition (DAS-II; Elliott, 2007) is an individually administered, norm-referenced instrument that assesses the cognitive abilities of children and adolescents ages 2 years, 6 months through 17 years, 11 months. 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).

The Differential Ability Scales Second Edition (DAS-II; Elliott, 2007) is an individually administered, norm-referenced instrument that assesses the cognitive abilities of children and adolescents ages 2 years, 6 months through 17 years, 11 months. Investigating the written language abilities of two individuals with Williams syndrome found that, despite the strong similarity between the two individuals in terms of their verbal and non-verbal cognitive abilities and their phonological abilities, their reading and spelling abilities differed by more than 5 grade levels. 2022 Aug 27;3(4):100138. doi: 10.1016/j.xhgg.2022.100138. 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. However, curve estimation revealed large mean differences that varied as a function of the child's cognitive ability level.
