摘 要:目的评价中文版肺功能状态和呼吸困难问卷(PFSDQ)修订版用于COPD患者的信度和效度。方法于2009年4—9月在北京市2家医院呼吸科门诊选取COPD稳定期患者61例,其中男52例,女9例;年龄51~80岁,平均(66±7)岁。用PFSDQ修订版和修订的英国医学委员会呼吸困难量表(MMRC量表)评估其呼吸困难及功能情况,并于同日或1周内进行检测肺功能和6min步行试验。PFSDQ修订版包括活动受限程度、活动后呼吸困难和活动后疲乏3个维度。结果PFSDQ修订版中活动受限、活动后呼吸困难和活动后疲乏3个维度的克龙巴赫仪系数分别为0.84、0.85和0.89,与6min步行距离、FEVl、FEV。/FVC、FEV.占预计值%、MMRC测评的呼吸困难程度和BODE指数均有显著相关性(,值为-0.27~0.66,均P〈0.01)。上述3个维度在病情严重程度不同的患者中进行两两比较,差异均有统计学意义()f。值为7.35~15.21,P〈0.05和P〈0.01)。结论中文版PFSDQ修订版在61例COPD患者中使用具有良好的信度和效度,适用于我国COPD患者。Objective To determine the reliability and validity of the modified pulmonary functional status and dyspnea questionnaire (PFSDQ-M) Chinese version in patients with chronic obstructive pulmonary disease (COPD) at 2 hospitals in Beijing, China. Methods PFSDQ-M has three domains, i.e. , change experienced by patient with activities or activity restriction ( CA), dyspnea with activities (DA) and fatigue with activities ( FA ). Sixty-one patients with COPD in stable condition were assessed by interview with PFSDQ-M Chinese version, modified Medical Research Council dyspnea scale (MMRC), respectively, and underwent pulmonary function test (PFT) and 6-minute walking test (6MWT) on the same day or within one week before interview. Results Cronbach' s alpha was 0. 84, 0. 85 and O. 89 for domains of CA, DA and FA of the PFSDQ-M, respectively. Scores of change in activities, dyspnea and fatigue with activities in patients of COPD correlated to their 6-minute walking distance ( r = - 0. 39 to - 0. 50), FEV1( r = - O. 28 to -0. 36), FEV1/FVC (r = -0.27 to -0. 37), FEV1% of predicted (r = -0.27 to -0.37), dyspnea score in MMRC ( r = 0. 59 to 0. 66) and BODE index ( r = 0. 40 to 0. 51 ), respectively ( all P 〈 0. 01 ). Degrees of restriction of activity, dyspnea and fatigue with activities varied significantly in patients with different severity of COPD ( X2 = 7.35 to 15.21, P 〈 O. 05, P 〈 0. 01, respectively). Conclusions Results of 61 patients with COPD interviewed with PFSDQ-M Chinese version suggest its good reliability and validity in discriminating patients with COPD of varied severity and stages.
