Abstract
Asthma prevalence are increasing worldwide causing many socioeconomic troubles which leads to the development of many questionnaires worldwide to measure the Validity and reliability of asthma prevalence. The first widely used questionnaire in respiratory epidemiology was the questionnaire from the Medical Research Council (MRC) of Great Britain. In the first version, from 1960, there were only a few questions about wheezing, but in later editions, more questions about asthma and asthma like symptoms were added. The MRC questionnaire initiated the development of other questionnaires such as the
European Community for Coal and Steel (ECSC) questionnaire of respiratory symptoms and the questionnaire from the American Thoracic Society and the Division of Lung Diseases (ATS-DLD-78).
