心脏康复阻碍因素量表的汉化及信效度检验

Reliability and validity of Chinese version of Cardiac Rehabilitation Barriers Scale

  • 摘要: 目的 对心脏康复阻碍量表(Cardiac Rehabilitation Barriers Scale,CRBS)进行汉化,探索适合中国冠心病患者的心脏康复阻碍因素评估工具。 方法 经加拿大约克大学Grace教授同意后,对英文版心脏康复阻碍因素量表进行翻译与回译、文化调试及可用性评价后形成中文版心脏康复阻碍因素量表(Chinese version of Cardiac Rehabilitation Barriers Scale,CRBS-C)。2018年3 - 7月,对本院心血管内科住院的具有心脏康复指征的冠心病患者进行问卷调查,评估量表信效度。 结果 本研究共发放问卷126份,回收有效问卷121份,完成率为96.03%。经过文化调试,删除原量表条目19,修改条目8语言表达,项目分析时删除原量表条目20。经探索性因子分析,提取特征值> 1的主因子5个,量表修订为5维度,命名上予以调整。修订后的量表各条目因子负荷均> 0.4,总量表Cronbach'sα系数为0.89,折半系数为0.86,各维度Cronbach'sα系数为0.73~0.91,折半系数为0.73~0.87。 结论 中文版CRBS包含5个维度共19条目,量表可用性、内容效度及内在一致性均较好,适合用于我国冠心病患者心脏康复的阻碍因素评估。

     

    Abstract: Objective To develop a Chinese version of Cardiac Rehabilitation Barriers Scale (CRBS) by translation, cultural adaption, item analysis, and test its reliability and validity, so as to provide an appropriate assessment tool for identifying the barriers that will prevent patients with coronary heart disease (CHD) from attending cardiac rehabilitation (CR). Methods After translating, cultural adaption and availability evaluation, we formed a Chinese version of CRBS (CRBS-C). From March to July in 2018, CHD patients with indication of CR who were hospitalized in cardiovascular department of Chinese PLA General Hospital were investigated by CRBS-C for testing its reliability and validity. Results A total of 126 patients were investigated and 121 of them responsively answered the questionnaire with a completion rate of 96.03%. During cultural adaption, we deleted item 19 and revised the expression of item 8. After item analysis, we deleted item 20. In exploratory factor analysis, 5 main factors with eigenvalue> 1 were extracted. So we revised its dimensions into 5 and renamed them. The factor loading of each revised item was above 0.40, the Cronbach's α and split-half reliability coefficient was 0.89 and 0.86 for the scale, ranged from 0.73 to 0.91 and 0.73 to 0.87 for each dimension. Conclusion The Chinese version of CRBS consists of 5 dimensions with 19 items, with good psychometric properties, which is appropriate to be used to assess the barriers of cardiac rehabilitation in Chinese patients with CHD.
