Abstract：
UNASSIGNED: To translate a disease-specific anxiety questionnaire on chronic obstructive pulmonary disease (COPD) and test its reliability and validity in China.
UNASSIGNED: The German version of the revised COPD Anxiety Questionnaire (CAF-R) was initially validated using step-by-step translation, back-translation, and cross-cultural adaptation. The reliability and validity of the Chinese version of the CAF-R (CAF-R-CN) were tested among 448 patients with COPD (mean age =71.42±9.33 years, 17.2% female) from four medical institutions in Suzhou, Jiangsu Province, using convenience sampling, from April 2022 to June 2023.
UNASSIGNED: The CAF-R-CN included six dimensions with a total of 25 items. The item-level content validity index was 0.860-1.000; the scale-level content validity index was 0.920. The structural validity χ2/df was 2.326, the root mean square error of approximation was 0.077, the comparative fit index was 0.924, and the Tucker-Lewis index was 0.912. The six-dimensional internal consistency index Cronbach\'s α coefficient was 0.696-0.910, and the test-retest reliability was 0.949. An optimal cut-off score of 50.5 was selected with a sensitivity of 0.786 and specificity of 0.870.
UNASSIGNED: The CAF-R-CN had satisfactory reliability and validity and can be used to identify and assess anxiety in COPD patients with a Chinese cultural background.

摘要：
■翻译针对慢性阻塞性肺疾病（COPD）的疾病特异性焦虑问卷，并检验其在中国的信度和效度。
■修订后的COPD焦虑问卷（CAF-R）的德语版最初使用逐步翻译进行验证，回译,和跨文化适应。在448例COPD患者中测试了中文版CAF-R（CAF-R-CN）的信度和效度（平均年龄=71.42±9.33岁，17.2%女性)来自苏州四家医疗机构，江苏省,使用方便采样，从2022年4月到2023年6月。
■CAF-R-CN包括六个维度，总共25个项目。项目级内容效度指数为0.860~1.000;量表级内容效度指数为0.920。结构效度χ2/df为2.326,近似均方根误差为0.077,比较拟合指数为0.924,Tucker-Lewis指数为0.912。六维内部一致性指数Cronbach'sα系数为0.696-0.910，重测信度为0.949。选择50.5的最佳截止评分,灵敏度为0.786,特异性为0.870。
■CAF-R-CN具有令人满意的信度和效度，可用于识别和评估具有中国文化背景的COPD患者的焦虑。
