At present, there is no research scale designed for the quality of life of children with chronic cough in China, most of them use the cough scale designed for adults to evaluate the quality of life of children. In China, more and more attention has been paid to evaluate and improve the quality of life of children with chronic cough, but cough specific quality of life measurement tools for adults and parents are mostly used, and the Chinese translation version of CQLQ and LCQ is still the main method. There is still no cough specific quality of life measurement tool for children with chronic cough in China. Cc-qol, a specific scale for chronic cough in children, has not been promoted, and no relevant verification of the applicability, validity and reliability of the Chinese version has been found. Therefore, this study aims to verify and compare the applicability, reliability and validity of CC-QOL Chinese version in China through questionnaire survey and follow-up of children with chronic cough.
