ABSTRACT
Cough is one of the three major symptoms reported by chronic obstructive pulmonary disease (COPD) patients. The Leicester Cough Questionnaire (LCQ) is a questionnaire exploring the impact of cough, but it does not exist in French. The aim of this study was to develop a French version of LCQ and to assess its psychometrics properties. A forward-backward translation process was used to develop the French version of the LCQ. COPD patients completed LCQ and Cough and Sputum Assessment Questionnaire (CASA-Q) to determine concurrent validity, content validity and internal consistency. Two weeks later, the LCQ was repeated to evaluate the reproducibility. Seventy-four COPD patients were recruited. The concurrent validity showed highly significant correlations between all scores of LCQ and CASA-Q (p < 0.001). The content validity was good with domain total scores correlations ranging from 0.918 to 0.953. The LCQ domains and total scores showed a very good internal consistency with Cronbach's α coefficients ranging between 0.802 and 0.917. The test-retest reliability was high in COPD patients with no change in cough. In conclusion, The French version of the LCQ is a valid and reliable instrument to measure health status in COPD patients.
