中文版急性冠脉综合征反应指数量表信度及效度研究

Reliability and validity of Chinese version of Acute Coronary Syndrome Response Index

目的:评价中文版急性冠脉综合征反应指数量表(C-ACSRI)的信度及效度。方法:采用翻译并修订的C-ACSRI对224例冠心病患者进行调查,并对结果进行信度、效度分析。结果:以Cronbach’sα系数检验总量表及态度、信念分量表的信度,Kuder-Rechardson 20(K-R20)系数检验知识分量表的信度,结果分别为0.81(总量表)、0.79(知识)、0.87(态度)、0.71(信念)。总量表的内容效度指数为0.93;分量表与总量表得分之间的相关系数为0.58～0.82,P<0.01;主成分分析经方差最大正交旋转后,知识分量表抽取2个因子共解释总方差的31.6%,态度、信念分量表抽取3个因子共解释总方差的61.0%。结论:中文版急性冠脉综合征反应指数量表具有良好的信度及效度,可作为临床医务人员和研究人员进行筛查、测量的工具。

Objective： To evaluate the reliability and validity of Chinese version of Acute Coronary Syndrome Response Index （C-ACSRI）. Methods： Acute Coronary Syndrome Response Index was translated and adapted according to Chinese culture. The reliability and validity of C-ACSRI was examined in 224 patients with coronary heart disease （CHD）. Results： The Cronbach＇s ct of the whole index was 0.81. The content validity was 0.93. The correlations between scores of each scale were low and it was high between each scale and the whole set of index. Principal component analysis with Varimax rotation was conducted for the knowledge subscale and attitudes and beliefs subscale in a separate analysis. Two factors extracted in the knowledge subscale which explained 31.6% of the variance. Three factors extracted in the attitudes and beliefs subscales which explained 61.0% of the variance. Conclusion： C-ACSRI is a reliable and valid measurement instrument, and can be used in the research and clinical setting to assess patients＇ knowledge, attitudes and beliefs towards acute coronary syndrome. It is helpful in predicting and decreasing the pre-hospital delay time in CHD patients in the onset of ACS attack.
