Translation and validation of the Chinese version of Pressure Ulcer Quality of Life Questionnaire / 中国实用护理杂志

ABSTRACT

Objective:To translate the Pressure Ulcer Quality of Life Questionnaire (PU-QOL) into Chinese and test its reliability and validity.Methods:The PU-QOL was translated, back translated, cross-cultural debugged and pre-investigated to form the Chinese version of PU-QOL. From August 2020 to November 2021, 405 patients with PU in wound clinics of two third-class hospitals in north and south regions of China were conveniently selected as the research objects.Results:The Chinese version of PU-QOL had 74 items. The content validity of the items was 0.80 to 1.00 and the content validity of the scale level was 0.95. Exploratory factor analysis extracted 7 common factors and the cumulative variance contribution rate was 60.79%. Each problem area is moderately correlated with the 12-Item Short Form Survey (SF-12), and the correlation coefficient between each dimension (0.13-0.28) was less than the correlation coefficient between each dimension and the total score of the scale and the difference was statistically significant( P<0.01). The Cronbach′s α coefficient was 0.84 and the retest reliability was 0.92. Conclusions:The Chinese version of PU-QOL questionnaire was proved to be a good instrument with acceptable reliability and validity, which can be used as a tool for evaluating quality of life of patients with PU in China.
