Combined symptoms of social communication impairments: promising signs for early screening of autism

Objectives: It's difficult to discover autism as early as possible for early intervention because no generally accepted effective signs could be used for early detection. This article aims to investigate high-frequency traits of autism and identify predictive signs for early screening. Methods: A comprehensive observation scale was completed by parents. The common traits of 228 cases of children who were diagnosed as typical autism were collected and analysed with SPSS24.0. Results: Impairments in "social communication" and "language development" are the most serious during the four aspects (P<0.01), whose mean response rate are 74.55% and 76.16% respectively. In "social communication", high- frequency traits with single response rate >= 90% has a significant difference than the single response rate<90% at the abnormal behavior appeared age of <= 18 months (P<0.01), and once they appeared it will be persistent and don't disappear with age (P>0.05). Conclusions: The results suggest that high- frequency combined traits in "social communication" could be used as early signs for screening and detection of autism.
