Abstract:
Objective:To translate the Understanding COPD (UCOPD) into Chinese, culturally adjust it and test its reliability and validity.Methods:According to the translation principle of Brislin questionnaire, the English version of UCOPD was translated, back-translated and culturally adjusted and pre-tested to form the Chinese version of UCOPD. From December 2020 to April 2021, a total of 101 COPD patients admitted to Tianjin Medical University General Hospital were enrolled using the convenient sampling method. The reliability and validity of the scale were tested.Results:The Chinese version of UCOPD included section A and B. Section A included 3 dimensions, such as "about COPD" "managing symptoms of COPD" "accessing help and support", with a total of 18 items. The results of exploratory factor analysis showed that the cumulative variance contribution rate of the three common factors was 59.35%. The Cronbach's α coefficient of section A was 0.893, and the Cronbach's α coefficient of each dimension was 0.756-0.864. The test-retest reliability of section A was 0.954, and the test-retest reliability of each dimension was 0.779-0.887. Section B included 6 items, which were used to measure the satisfaction of pulmonary rehabilitation courses in COPD patients. However there were big individual differences, so the reliability and validity test of section B were not evaluated.Conclusions:Section A of the Chinese version of UCOPD questionnaire has good reliability and validity. It can be used to evaluate self management ability of patients with good knowledge of COPD but less confidence in symptom control and health maintenance, so as to guide clinical medical staff to formulate accurate intervention measures to improve patients' self management.
