Back translation was adopted to ensure accuracy of the translation. A total of 155 COPD patients were recruited to test the reliability and validity of the D\u201012\u2010C scale. Internal reliability and test\u2010retest reliability were measured with Cronbach's alpha coefficient and intra\u2010class correlation coefficient, respectively. Construct validity was assessed through exploratory factor analysis (EFA). Concurrent validity was assessed by the correlation of D\u201012\u2010C total score and sub\u2010scores and the Chinese version of Saint George's Respiratory Questionnaire (SGRQ), 36\u2010Item Short Form Health Survey (SF\u201036), COPD Assessment Test (CAT) and Hospital Anxiety and Depression Scale (HADS) total score and sub\u2010scores.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The two\u2010factor structure of D\u201012\u2010C was confirmed by EFA.
