To describe the intra-rater and inter-rater reliability of the Brazilian Portuguese version of the fatigue severity scale (FSS) in patients with COPD and to identify the presence of its association with parameters of pulmonary function, dyspnea, and functional capacity.
This was an observational cross-sectional study involving 50 patients with COPD, who completed the FSS in interviews with two researchers in two visits. The FSS scores were correlated with those of the Medical Research Council (MRC) scale, as well as with FEV1, FVC, and six-minute walk distance (6MWD).
The mean age of the patients was 69.4 ± 8.23 years, whereas the mean FEV1 was 46.5 ± 20.4% of the predicted value. The scale was reliable, with an intraclass correlation coefficient of 0.90 (95% CI, 0.81-0.94; p < 0.01). The FSS scores showed significant correlations with those of MRC scale (r = 0.70; p < 0.01), as well as with 6MWD (r = -0.77; p < 0.01), FEV1 (r = -0.38; p < 0.01), FVC (r = -0.35; p < 0.01), and stage of the disease in accordance with the Global Initiative for Chronic Obstructive Lung Disease criteria (r = 0.37; p < 0.01).
The Brazilian Portuguese version of the FSS proved reliable for use in COPD patients in Brazil and showed significant correlations with sensation of dyspnea, functional capacity, pulmonary function, and stage of the disease.
描述巴西葡萄牙语版疲劳严重程度量表（FSS）在 COPD 患者中的内部和外部信度，并确定其与肺功能、呼吸困难和功能能力参数的关联。
这是一项观察性的横断面研究，涉及 50 名 COPD 患者，他们在两次就诊时通过两名研究人员的访谈完成了 FSS 调查。FSS 评分与 MRC 量表的评分以及 FEV1、FVC 和 6 分钟步行距离（6MWD）相关。
患者的平均年龄为 69.4 ± 8.23 岁，平均 FEV1 为预计值的 46.5 ± 20.4%。该量表具有可靠性，组内相关系数为 0.90（95%CI，0.81-0.94；p<0.01）。FSS 评分与 MRC 量表评分（r=0.70；p<0.01）、6MWD（r=-0.77；p<0.01）、FEV1（r=-0.38；p<0.01）、FVC（r=-0.35；p<0.01）和与全球倡议慢性阻塞性肺疾病标准相符的疾病阶段（r=0.37；p<0.01）均呈显著相关性。
巴西葡萄牙语版 FSS 对巴西 COPD 患者是可靠的，并且与呼吸困难的感觉、功能能力、肺功能和疾病阶段有显著相关性。
