Expressive language sampling is a useful tool for measuring Communication Development in youth with down syndrome. The study, co-led by Angela Thurman and Leonard Abbeduto from the UC Davis Mind Institute and the Department of Psychiatry and Behavioral Sciences, focused on language as an outcome measure to detect meaningful changes in communication skills.
Interventions leading to improvements in the language would have great impacts on the quality of life of individuals with Down syndrome. To develop and evaluate such interventions, we need a validated measurement tool and ELS provides that.” said Leonard Abbeduto, Director, UC Davis MIND Institute, Professor of Psychiatry and Behavioral Sciences, and Study Senior Author.
The ELS procedure covers two types of natural interactions from the participants: conversation and narration. In conversation, trained examiners engage participants on a variety of topics in a sequence and standardized manner. On the other hand, in narration, the participants independently construct and tell the story in a wordless picture book. The process intensity matters the most as the repetitive mistakes are calculated. Following that the mistakes are eliminated with continuous lessons which help to solve the intellectual disabilities of youths with down syndrome.
