心律失常患者健康相关生活质量量表的汉化及信效度研究

Chinese Translation of Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia Health-Related Quality of Life and Its Reliability and Validity Test

目的对心律失常患者健康相关生活质量(ASTA‑HRQoL)量表进行汉化翻译并验证其在快速性心律失常患者中的信度和效度。方法对ASTA‑HRQoL量表进行翻译及跨文化调适,并于2019年10月至2020年10月采用便利抽样法对沈阳市某三级甲等医院的192例快速性心律失常患者进行调查,评定量表的信度和效度。结果中文版ASTA‑HRQoL量表的Cronbach’sα系数为0.887,折半信度为0.866;量表水平的内容效度指数和条目水平的内容效度指数均为1.0。验证性因子分析显示,量表所有条目的因子载荷均在0.5以上,模型拟合指标中卡方/自由度为1.926,近似误差均方根为0.078,拟合优度指数为0.891,比较拟合指数为0.927,递增拟合指数为0.928,Tucker‑Lewis指数为0.911。量表2个维度的组合信度分别为0.872和0.842,平均方差抽取量分别为0.495和0.472;2个维度之间具有显著相关性(P<0.01),相关性系数绝对值小于0.5且均小于对应的平均方差抽取量的平方根。结论中文版ASTA‑HRQoL量表信效度良好,适用于评估我国快速性心律失常患者的健康相关生活质量。

Objective To translate the Arrhythmia‑Specific Questionnaire in Tachycardia and Arrhythmia Health‑Related Quality of Life(ASTA‑HRQoL)into Chinese and test its reliability and validity in patients with tachyarrhythmia.Methods The ASTA‑HRQoL scale was translated and crossculturally adapted into Chinese.From October 2019 to October 2020,192 patients with tachyarrhythmia in a GradeⅢ‑A hospital in Shenyang were selected by convenience sampling to test the reliability and validity of the scale.Results For the Chinese version of ASTA‑HRQoL,the Cronbach's alpha was 0.887,the split‑half reliability was 0.866,and both the scale‑level content validity index and item‑level content validity index were 1.0.Confirmatory factor analysis showed that the factor loading was above 0.5 for all items,the chi‑square for model fit/degree of freedom was 1.926,the root mean square error of approximation was 0.078,the goodness‑of‑fit index was 0.891,the comparative fit index was 0.927,the incremental fit index was 0.928,and the Tucker‑Lewis index was 0.911.For the two dimensions of the scale,the composite reliability was 0.872 and 0.842,respectively,and the average variance extracted was 0.495 and 0.472,respectively;there was a significant correlation between the two dimensions(P<0.01),with the absolute value of the correlation coefficient less than 0.5 and also less than the square root of the corresponding average variance extracted.Conclusion With good reliability and validity,the Chinese version of ASTA‑HRQoL is suitable for assessing the health‑related quality of life in patients with tachyarrhythmia in China.
