A total of 4137 children with normal development and 448 children with abnormal development aged from 2 to 6 years old will be selected from 11 hospitals in China by multi-center, stratified, unequal proportion random sampling and face-to-face survey. Children's speech and language development was assessed by the Speech and Language Development Scale for children aged 2 to 6, compiled by the Linguistics and Language Research Centre of the Education University of Hong Kong.

The speech and Language Development Scale for children aged 2 to 6 was developed by the Linguistics and Language Research Center of the Education University of Hong Kong. It was divided into three parts: phonological assessment (word pronunciation), vocabulary assessment (comprehension and expression) and grammar assessment (comprehension). Color hand-painted pictures were used for the evaluation of the three types of items, and words were named by pictures, and words were selected by listening and listening, so as to ensure the practicality and conciseness of the scale, as well as the simplicity of operation and implementation. Finally, the total score of each subject was calculated and relevant developmental status conclusions were drawn.
