摘　　要：目的评价中文版明尼苏达心功能不全生命质量(MLHFQ)量表在慢型克山病患者中应用的信度和效度。方法选择2018年8月至2020年4月甘肃省克山病病区确诊的慢型克山病患者作为调查对象, 分析中文版MLHFQ量表用于慢型克山病患者生存质量评价的信度和效度。采用克伦巴赫(Cronbach′s)α系数, 评价该量表信度, Cronbach′s α系数> 0.8表示量表一致性信度良好。采用Kaider-Meyer-Olkin(KMO)统计量、巴特利特(Barlett′s)球形检验, 评价该量表是否适用于因子分析(KMO值> 0.6且Barlett′s球形检验P < 0.05为适用)。采用探索性因子分析方法的主成分分析法和最大方差法旋转提取公因子, 评价该量表结构效度。通过美国纽约心脏病协会(NYHA)心功能分级, 采用方差分析, 评价该量表区分效度。采用Pearson相关分析法, 评价该量表内容效度。结果共收集333份调查问卷, 合格问卷329份。调查对象中男性180人、女性149人, 年龄为(59.52 ± 9.26)岁。中文版MLHFQ量表的Cronbach′s α系数为0.95( > 0.8)。其中身体领域、情绪领域、其他领域Cronbach′s α系数分别为0.93、0.91、0.86(均> 0.8)。中文版MLHFQ量表KMO值为0.95( > 0.6), Barlett′s球形检验拒绝假设(χ^(2) = 5 222.01, P < 0.05)。主成分分析及最大方差法旋转提取得到3个公因子, 分别命名为生活动能、身体状况、情绪状况, 主成分累积贡献率为66.22%( > 50%)。NYHA心功能分级Ⅱ级患者与Ⅲ、Ⅳ级患者相比, 在身体领域、其他领域及总分方面, 差异均有统计学意义(P均< 0.001)。身体领域、情绪领域、其他领域与其所属条目之间的Pearson相关系数范围分别为0.74 ~ 0.88、0.78 ~ 0.90、0.56 ~ 0.80, 均> 0.5(P均< 0.001)。结论中文版MLHFQ量表在甘肃省慢型克山病患者中应用的信度和效度良好, 可用于对慢型克山病患者进行生存质量评价。Objective To evaluate the reliability and validity of Chinese version of Minnesota Living with Heart Failure Questionnaire(MLHFQ)scale among patients with chronic Keshan disease.Methods The patients with chronic Keshan disease diagnosed in Keshan disease area of Gansu Province from August 2018 to April 2020 were selected as the survey subjects to analyze the reliability and validity of the Chinese version of MLHFQ scale in evaluating the quality of life of patients with chronic Keshan disease.To evaluate the reliability of MLHFQ scale,the Cronbach'sαcoefficient was used,and when the Cronbach'sαcoefficient>0.8 indicated that the consistency reliability of the scale was good.Kaider-Meyer-Olkin(KMO)statistic and Barlett's sphericity test were used to evaluate whether the scale was suitable for factor analysis(applicable when KMO>0.6 and Barlett's sphericity test P<0.05).The principal component analysis and maximum variance method of exploratory factor analysis were used to extract common factors,and the structural validity of the scale was evaluated.The discrimination validity of the scale was evaluated by New York Heart Association(NYHA)cardiac function classification and analysis of variance.Pearson correlation analysis was used to evaluate the content validity of the scale.Results A total of 333 questionnaires were collected,of which 329 were valid.There were 180 males and 149 females,aged(59.52±9.26)years.The Cronbach'sαcoefficient of the Chinese version of MLHFQ scale was 0.95(>0.8).Among them,the Cronbach'sαcoefficients in the physical domain,emotional domain and other domains were 0.93,0.91 and 0.86,respectively(>0.8).The KMO value of the Chinese version of MLHFQ scale was 0.95(>0.6),and Barlett's sphericity test rejected the hypothesis(χ^(2)=5222.01,P<0.05).Principal component analysis and maximum variance method were used to extract 3 common factors,which were named kinetic energy of life,physical condition and emotional condition,respectively.The cumulative contribution rate of principal components w
