Erxin Scales

This book, drawing from internationally renowned scales like Bayley and Gesell, develops a child developmental assessment scale based on research data from Chinese children. It stands as a meticulous creation of the Capital Institute of Pediatrics, a national-level institution for children?s development research in China. The scale demonstrates good reliability and validity, meeting psychometric standards in various statistical aspects. In the revised scale, developmental quotients are classified into six levels, distributions of percentiles for developmental quotients are provided, and screening indices for autism spectrum disorders are added. In doing so, the revised scale can not only identify developmental delays but also concurrently screen for autism spectrum disorder risks, providing a foundational reference for tracking children?s developmental status in follow-up studies. The book holds vital value and significance in fostering communication among scholars from universities and research institutions, as well as pediatricians, neurologists, and rehabilitation specialists in hospitals.
