Study Description

Brief Summary

The purpose of this study is to establish a new Chinese children's speech and language norm by obtaining the latest data of speech and language development of children aged 2 ~ 6 from different regions in China. At the same time, the overall development level and group differences of speech and language in Chinese children aged 2 to 6 years, and the influencing factors of speech and language development in Chinese children aged 2 to 6 years were also discussed.

Condition or Disease	Intervention/Treatment	Phase
Mental Retardation Autism Spectrum Disorder Attention Deficit Hyperactivity Disorder	Other: establish a new Chinese children's speech and language norm

Detailed Description

To establish the norm of speech and language development in Chinese children aged 2 to 6 1063 normally developing children and 96 abnormally developing children will be retrospectively enrolled from the medical records of stratified, randomly selected centers. 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.
To investigate and analyze the present situation of speech and language development of children aged 2-6 in China The present situation of children's speech and language development was analyzed, and the differences of gender, age, birth and other influencing factors were statistically analyzed.

Outcome Measures

Primary Outcome Measures

Chinese children's speech and language norm [2021.11.1-2023.5.1]
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.
