Abstract:

Objective To translate the European Heart Failure Self-care Behaviour Scale for Caregivers （EHFScBS-C） into Chinese,and to test its reliability and validity. Methods The English version of EHFScBS-C was translated into Chinese and back translated according to the Brislin model. The Chinese version of the scale was determined after cross-cultural adaptation and pre-experiment. A convenience sample of 336 caregivers of patients with chronic heart failure in outpatient settings of 3 tertiary hospitals in Shandong Province were investigated. The test-retest data of 34 caregivers were collected by the follow-up of telephone or Wechat. The reliability and validity of the scale were evaluated. Results The Chinese version of EHFScBS-C contained 9 items. Exploratory factor analysis showed that a total of 2 factors were extracted explaining 67.453% of the total variance,namely caregiver’s contributions to self-care related to medical issues and caregiver’s contributions to self-care related to lifestyle. Confirmatory factor analysis supported the hypothesis of first-order two-factor model,and all fitting indexes were at acceptable level. The item-level content validity index of the Chinese version of EHFScBS-C was 0.83~1.00,and the scale-level content validity index was 0.97. The Cronbach’s α coefficient of the total scale was 0.873,and the test-retest reliability of the total scale was 0.858. Conclusion The Chinese version of EHFScBS-C has good reliability and validity,and it can be used as a reliable tool to evaluate caregiver contributions to heart failure self-care.

摘要：

目的 汉化欧洲心力衰竭患者照顾者自我护理贡献量表（the European Heart Failure Self-care Behaviour Scale for Caregivers,EHFScBS-C）,并检验其信效度。 方法 依照Brislin模型对原量表进行翻译和回译,经文化调适和预测试后,形成中文版EHFScBS-C。采用便利抽样法,2021年8月—11月对山东省3所三级甲等医院心力衰竭门诊就诊的336例慢性心力衰竭患者照顾者进行调查,并随机抽取34名照顾者于调查2周后通过电话或微信随访收集重测问卷资料,以评价该量表的信效度。 结果 中文版EHFScBS-C共9个条目,经探索性因子分析共提取2个公因子,分别命名为对医疗问题相关自我护理的贡献、对生活方式相关自我护理的贡献,累计方差贡献率为67.453%。验证性因子分析支持一阶二因子模型假设,各项拟合指标均在可接受水平。中文版EHFScBS-C条目的内容效度指数为0.83~1.00,量表的内容效度指数为0.97。量表总体的Cronbach’s α系数为0.873,重测信度为0.858。 结论 中文版EHFScBS-C具有良好的信效度,可作为评估照顾者对慢性心力衰竭患者自我护理贡献度的可靠工具。
