Abstract: Objective　The aim of this paper was to investigate the reliability and validity of the Chronic respiratory disease questionnaire (CRQ) in China. Method　Sixty-eight patients with chronic respiratory disease who were in hospital from January to November, 1999 were surveyed with CRQ. Eighteen patients were investigated repeatly with CRQ in one week to test the reliability; before and the 10th day after treatment, 50 patients were surveyed twice with CRQ and the peakflow of these patients were also detected. The same doctor explained questionnaires and tested peakflow. Results　The correlated analysis of reliability was positive (r=0.732, P<0.01). The correlatied analysis between the difference of twice-questionnaire scores and the difference of twice-peakflow value was also positive (r=0.565, P<0.01).Conclusion　CRQ can be used by the clinical doctors of China.
