Abstract

OBJECTIVE
To translate the English version of the London Chest Activity of Daily Living scale (LCADL) into a Korean version and to determine the reliability and validity of the Korean version in patients with chronic obstructive 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 final K-LCADL was obtained. To evaluate the validation of the K-LCADL, patients simultaneously completed a pulmonary function test, a 6-Minute Walk Test (6MWT), and questionnaires, including the modified Medical Research 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-5 Dimensions (K-EQ-5D). To assess test-retest reliability, the K-LCADL was again administered to the same patients within 2 weeks from initial assessment.
RESULTS
A total of 94 patients participated in the present study. The total K-LCADL score was positively correlated with 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), forced expiratory volume in one second 1 (r=−0.416, p=0.002), and forced vital capacity (r=−0.397, p=0.023). Intraclass correlation 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 living in patients with COPD.
