Objective: To translate the English version of the London Chest Activity of Daily Living scale (LCADL) intoa Korean version and to determine the reliability and validity of the Korean version in patients with chronicobstructive pulmonary disease (COPD).
Methods: The English version of LCADL was translated into Korean and back-translated into English.Subsequently, the back-translated version was reviewed and compared with the original, and thus the finalK-LCADL was obtained. To evaluate the validation of the K-LCADL, patients simultaneously completed apulmonary function test, a 6-Minute Walk Test (6MWT), and questionnaires, including the modified MedicalResearch Council (mMRC) dyspnea scale, the Korean version of the St. George’s Respiratory Questionnaire(K-SGRQ), the Korean version of the COPD Assessment Test (K-CAT), and the Korean version of the EuroQoL-5Dimensions (K-EQ-5D). To assess test-retest reliability, the K-LCADL was again administered to the same patientswithin 2 weeks from initial assessment.
Results: A total of 94 patients participated in the present study. The total K-LCADL score was positively correlatedwith the K-SGRQ (r=0.802, p<0.001), the mMRC dyspnea scale (r=0.603, p<0.001), and the K-CAT score (r=0.714,p<0.001), and negatively correlated with the K-EQ-5D (r=-0.764, p<0.001), 6MWT (r=-0.635, p<0.001), forcedexpiratory volume in one second 1 (r=-0.416, p=0.002), and forced vital capacity (r=-0.397, p=0.023). Intraclasscorrelation coefficient of the K-LCADL was 0.951 (p<0.001).
Conclusion: The K-LCADL is a reliable and valid questionnaire for evaluating limitation of activities of daily livingin patients with COPD.
