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.
