Analysis of the Reliability and Validity of the Chinese Version of CC-QoL

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
Descriptive Score: CC-QOL, CET,VAS, Peds-QOL,SCAS and Verbal category Score (VCD); descriptive score: DESCRIPTIVE score; descriptive score: DESCRIPTIVE score; descriptive score: DESCRIPTIVE score; To evaluate the reliability and validity of Cc-QOL in evaluating children's quality of life in China, Compare and analyze Leicester cough questionnaire(LCQ) and child chronic cough-specific quality of life measure Cc-qol was used to evaluate the quality of life in children with chronic cough.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Validity | Validity mainly evaluates the accuracy, validity and correctness of the scale, that is, the deviation between the measured value and the true target value.Validity is meant to reflect whether a measuring tool can effectively measure what it is intended to measure, that is, the extent to which the actual measured results agree with the expected results. | At first visit, before medication, 2 weeks and 6 weeks after treatment initiation | 
| Reliability | Reliability refers to the reliability, stability and consistency of the survey results, that is, accuracy.It is generally believed that reliability reflects the variation degree caused by measurement error or observation error, that is, random error.Common indicators: Common indicators: It is generally believed that Cronbach's alpha should be above 0.7. Retest reliability: the same questionnaire is used to measure the same group of respondents repeatedly at different times, and the consistency between the two results is retest reliability. | At first visit, before medication, 2 weeks and 6 weeks after treatment initiation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensitivity | To evaluate the sensitivity of the questionnaire to measurements before and after treatment | At first visit, before medication, 2 weeks and 6 weeks after treatment initiation |
