Abstract

Background: The object of this study was to assess the validity and reliability of the Korean versions of chronic obstructive pulmonary disease assessment test (CAT) and Dyspnea-12 Questionnaire for patients with chronic pulmonary obstructive disease (COPD). Methods: For the 127 COPD patients, we obtained the Korean versions of the 3 questionnaires being tested: St George’s Respiratory Questionnaire (SGRQ), CAT, and Dyspnea-12 with spirometric measurements. To assess the validity of CAT and Dyspnea-12, their correlation with SGRQ was evaluated. To assess the reliability of CAT and Dyspnea-12, Cronbach’s alpha coefficient was evaluated. Results: The mean age of patient participants was 68.6±7.5 years; 97.6% were male. The SGRQ score was correlated with the scores of the Korean version of CAT (r=0.71, p＜0.0001) and Dyspnea-12 (r=0.73, p＜0.0001). The Cronbach’s alpha coefficient for the CAT and Dyspnea-12 were 0.77 and 0.78, respectively. Conclusion: The Korean versions of CAT and Dyspnea-12 were shown to be valid and reliable for the Korean COPD patients.
