Standardized respiratory questionnaires: comparison of the old with the new.
Two standardized respiratory questionnaires were administered to 946 white male participants in a long-term study of respiratory symptoms in Washington County, Md. One half of the men were given the 1960 respiratory questionnaire developed by the British Medical Research Council (MRC) at the start of the interview and a new questionnaire developed by the American Thoracic Society and the Division of Lung Diseases (ATS-DLD) at the end. The order was reversed for the other half of the subjects. No important differences were found in the responses. To obtain a minimal basic history for evaluation of chronic obstructive pulmonary disease, either the MRC questionnaire or the corresponding questions from the ATS-DLD questionnaire may be used. More detailed information on a wider variety of historical items may be obtained by using the ATS-DLD questionnaire.
