Commonly applied measures of symptoms of anxiety are not sensitive to disease-specific anxiety in patients with chronic obstructive pulmonary disease (COPD). There is a need for validated instruments measuring COPD-specific anxiety. Therefore, we translated the COPD-Anxiety Questionnaire (CAF) into Danish (CAF-R-DK) and performed an initial validation of the psychometric properties in a sample of patients with COPD.
Translation procedures followed the World Health Organization guidelines. Participants with COPD completed questionnaires measuring COPD-specific anxiety (CAF-R-DK), general psychological distress (Hospital Anxiety and Depression Scale) as well as variables related to COPD (COPD Assessment Test; modified Medical Research Council dyspnea scale), quality of life (the 12-item Short Form survey, SF12), and socio-demography.
A total of 260 patients with COPD (mean age: 65.0, 69% female) completed questionnaires. The Danish version of CAF-R-DK demonstrated acceptable Cronbach's α values that were comparable with those of the original CAF. As expected, the CAF-R-DK showed positive correlations with convergent constructs (CAT; HADS) and negative correlations with discriminant constructs (SF-12). However, the results for specific subdomains of the CAF-R-DK indicated inconsistency in the underlying concept of disease-specific anxiety, which was also suggested based on the subsequent confirmatory and exploratory factor analyzes.
The CAF could serve as an important supplement to generic psychological distress screening of patients with COPD in somatic health care settings, and the questionnaire is now available in Danish. Translation into other languages is needed with the purpose of obtaining data for further testing the psychometric properties of the questionnaire.
常用的焦虑症状测量方法对慢性阻塞性肺疾病（COPD）患者的疾病特异性焦虑不敏感。需要经过验证的测量COPD特异性焦虑的工具。因此，我们将COPD焦虑问卷（CAF）翻译成丹麦语（CAF-R-DK），并在一组COPD患者样本中对其心理测量特性进行了初步验证。
翻译程序遵循世界卫生组织的指南。COPD患者完成了测量COPD特异性焦虑（CAF-R-DK）、一般心理困扰（医院焦虑抑郁量表）以及与COPD相关变量（COPD评估测试；改良医学研究理事会呼吸困难量表）、生活质量（12项简短问卷调查，SF12）和社会人口统计学的问卷。
共有260名COPD患者（平均年龄：65.0岁，69%为女性）完成了问卷。丹麦版的CAF-R-DK显示出可接受的克朗巴赫α值，与原始CAF相当。正如预期的那样，CAF-R-DK与收敛性构念（CAT；HADS）呈正相关，与区分性构念（SF-12）呈负相关。然而，CAF-R-DK特定子领域的结果表明，疾病特异性焦虑的潜在概念存在不一致性，后续的验证性和探索性因素分析也表明了这一点。
CAF可作为躯体医疗环境中COPD患者一般心理困扰筛查的重要补充，该问卷现已提供丹麦语版本。需要翻译成其他语言，以便获得数据进一步测试该问卷的心理测量特性。
