Dyspnoea-12 assesses dyspnea based on the physical and affective components of the symptom. The aim of this study was to translate the Dyspnoea-12 into Portuguese, and to obtain validation data regarding the use of this tool in patients with chronic obstructive lung disease (COPD).
The English version of the scale Dyspnoea-12 underwent a formal translation process into Portuguese as spoken in Brazil with the final version being called Dyspnoea-12-Pt. The latter was applied to 51 Portuguese-speaking patients with COPD (33 men; age: 66.4 ± 8.1 years; FEV : 48.7% ± 17.2% pred). Participants also completed the Medical Research Council dyspnea scale (MRC), the Baseline Dyspnea Index (BDI), the Hospital Anxiety and Depression scale, the Saint George's Respiratory Questionnaire (SGRQ) and performed spirometry and the Six-Minute Walk Test (6 MWT). Forty-five volunteers in stable clinical conditions also completed the Dyspnoea-12-Pt scale approximately 2 weeks after the first evaluation.
Dyspnoea-12-Pt showed significant correlations with the scales MRC (r = 0.494), BDI (r = -0.511), SGRQ (r = 0.806), Anxiety (r = 0.471), Depression (0.414) and walked distance in the 6 MWT (r = 0.329). Cronbach's alpha of Dyspnoea-12-Pt total was 0.921 and the intraclass correlation coefficient between sequential measures was 0.829.
The scale Dyspnoea-12-Pt exhibits acceptable psychometric properties and may be used as an evaluation tool of dyspnea in Portuguese speaking COPD patients.
呼吸困难-12量表基于症状的身体和情感成分来评估呼吸困难。本研究的目的是将呼吸困难-12量表翻译成葡萄牙语，并获取关于该工具在慢性阻塞性肺疾病（COPD）患者中使用的验证数据。
将英文版的呼吸困难-12量表按照巴西葡萄牙语进行正式翻译，最终版本称为呼吸困难-12-Pt。该量表应用于51名讲葡萄牙语的COPD患者（33名男性；年龄：66.4±8.1岁；第一秒用力呼气容积：占预计值的48.7%±17.2%）。参与者还完成了医学研究委员会呼吸困难量表（MRC）、基线呼吸困难指数（BDI）、医院焦虑抑郁量表、圣乔治呼吸问卷（SGRQ），并进行了肺功能测定和六分钟步行试验（6MWT）。45名临床状况稳定的志愿者在首次评估约2周后也完成了呼吸困难-12-Pt量表。
呼吸困难-12-Pt量表与MRC量表（r = 0.494）、BDI量表（r = -0.511）、SGRQ量表（r = 0.806）、焦虑量表（r = 0.471）、抑郁量表（0.414）以及6MWT中的步行距离（r = 0.329）显示出显著相关性。呼吸困难-12-Pt总量表的Cronbach's α系数为0.921，连续测量之间的组内相关系数为0.829。
呼吸困难-12-Pt量表具有可接受的心理测量学特性，可作为评估讲葡萄牙语的COPD患者呼吸困难的工具。
