Objective To translate the English version of the Uremic Pruritus in Dialysis Patients Scale (UP-Dial) into Chinese, and to test its reliability and validity. Methods According to the Brislin’s translation model, the English version of UP-Dial was subjected to translation, back-translation and cultural adjustment to form the Chinese version of UP-Dial. Reliability and validity of the Chinese UP-Dial were evaluated through investigation among 132 patients in Peking University People’s Hospital. Results The Chinese UP-Dial contained 11 items. The exploratory factor analysis extracted 3 common factors, and the cumulative variance contribution rate was 69.981%. The content validity index of the total scale was 0.93. The Chinese UP-Dial and numerical rating scale were highly correlated (r=0.687, P＜0.001). The Cronbach's α coefficient of the total scale was 0.931, and the rest-retest reliability of the total scale was 0.875. Conclusion The Chinese version of UP-Dial has better reliability and validity. It can be used to evaluate pruritus in dialysis patients.
