Dyspnea is a distressing symptom experienced by people with chronic obstructive pulmonary disease (COPD). The dyspnea-12 (D-12) questionnaire comprises of 12 items and assesses the quality of this symptom, its severity and the emotional response. The original (English) version of the D-12 is reliable and valid for the measurement of dyspnea in pulmonary diseases.
To translate the D-12 into Arabic and determine whether this version is reliable and valid in Saudi nationals with COPD.
The D-12 was translated into Arabic version and reviewed by an expert panel before being back-translated into English. The Arabic version was administered to five patients with COPD to test whether it was easily understood after which a final Arabic version was produced. Thereafter, 40 patients with COPD (aged 63 9 years; 33 [82.5%] males; forced expiratory volume in one second (FEV 1) 47 16% predicted) completed the D-12, the COPD Assessment Test (CAT) and the Chronic Respiratory Disease Questionnaire (CRDQ). Lung function and 6-minute walk distance were also measured. The D-12 was re-administered two weeks later.
The Arabic version of the D-12 demonstrated good reliability over the two administration (intraclass correlation coefficient = 0.94, P = 0.01). Strong associations were demonstrated between the (1) total score for the D-12 and the CAT, (2) quality sub-score of the D-12 and the CAT and (3) emotional response sub-score of the D-12 and emotional function domain of the CRDQ (r ≥ 0.6, all P < 0.01).
The Arabic version of the D-12 is a reliable and valid instrument in Saudi nationals with COPD.
呼吸困难是慢性阻塞性肺疾病（COPD）患者经历的一种痛苦症状。呼吸困难-12（D-12）问卷由12个项目组成，评估该症状的性质、严重程度和情绪反应。D-12的原始（英文）版本在测量肺部疾病的呼吸困难方面具有可靠性和有效性。
将D-12翻译成阿拉伯语，并确定该版本在沙特阿拉伯COPD患者中是否可靠且有效。
将D-12翻译成阿拉伯语版本，并在回译成英语之前由专家小组进行审核。将阿拉伯语版本应用于5例COPD患者以测试其是否易于理解，之后生成最终的阿拉伯语版本。此后，40例COPD患者（年龄63±9岁；33例[82.5%]为男性；一秒用力呼气容积（FEV1）为预测值的47±16%）完成了D-12、COPD评估测试（CAT）和慢性呼吸道疾病问卷（CRDQ）。还测量了肺功能和6分钟步行距离。两周后再次进行D-12测试。
D-12的阿拉伯语版本在两次测试中显示出良好的可靠性（组内相关系数=0.94，P=0.01）。在以下方面显示出强相关性：（1）D-12总分与CAT；（2）D-12性质子分数与CAT；（3）D-12情绪反应子分数与CRDQ的情绪功能领域（r≥0.6，所有P<0.01）。
D-12的阿拉伯语版本在沙特阿拉伯COPD患者中是一种可靠且有效的工具。
