Abstract:

Objective To translate the English version of Thirst Distress Scale with Heart Failure（TDS-HF） into Chinese and test the reliability and validity of the Chinese version of TDS-HF.Methods The English version of TDS-HF was translated into Chinese and back translated and modified for cultural adaptation according to the guidelines. A convenience sample of 268 heart failure patients at one tertiary hospital in Tianjin was investigated using the Chinese version of TDS-HF to test its reliability and validity.Results The Cronbach’s α of the Chinese version of TDS-HF was 0.925. Both the scale-level content validity index and the item-level content validity index were 1. Factor analysis showed a single factor explaining 65.56% of the total variance. The score of TDS-HF was significantly associated with the thirst intensity score（r=0.601,P<0.001）.Conclusion The Chinese version of TDS-HF has been proved to be reliable and valid. It can be used for measuring thirst distress in patients with heart failure.

摘要：

目的 翻译英文版心力衰竭患者口渴困扰量表（Thirst Distress Scale for Patients with Heart Failure,TDS-HF）,并对中文版TDS-HF进行信效度检验。方法 严格遵循量表引进原则,对量表进行翻译、回译和跨文化调试。便利选取在天津市某三级甲等医院心脏中心住院治疗的268例心力衰竭患者进行调查,采用SPSS 17.0进行统计学分析,计算中文版TDS-HF的信效度。结果 中文版TDS-HF的Cronbach’s α系数为0.925;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,共提取1个公因子,方差贡献率为65.56%;量表总分与口渴强度数字评分呈正相关（r=0.601,P<0.001）。结论 中文版TDS-HF具有良好的信度和效度,可用于评价国内心力衰竭患者的口渴困扰程度。
