ABSTRACT
Objective To translate The Pressure Ulcer Risk Primary or Secondary Evaluation Tool (PURPOSE-T) into Chinese,and assess its reliability and validity in Chinese hospitalized patients. Methods The original PURPOSE-T was translated into Chinese and back translated and modified for cultural adaptation according to guidelines.The reliability and validity of the Chinese version of PURPOSE-T were tested in 230 hospitalized patients. Results The Chinese version of PURPOSE-T consists of three parts and contains 25 entries. The inter-rater consistency Kappa coefficient was 0.798, the weighted Kappa coefficient was 0.843. The evaluation results were compared with binary variables with a Kappa coefficient of 0.745. The test-retest reliability Kappa coefficient and the weighted Kappa coefficient were 0.863 and 0.892. Two classified assessment Kappa coefficient was 0.857. The item content validity index ranged from 0.83 to 1.00, and the scale content validity index was 0.98. The phi correlation coefficient of PURPOSE-T and Braden scale was 0.781; the phi correlation coefficient of Waterlow Scale evaluation result was 0.777. The correlation coefficient between Chinese PURPOSE-T items and Braden scale items ranged from 0.605 to 0.877 (P<0.01), and the Waterlow Scale items ranged from 0.599 to 0.887 (P<0.01). Conclusions The Chinese version of PURPOSE-T appears to possess adequate validity, test-retest reliability and internal consistency. The newly translated Chinese version of PURPOSE-T may be used to assess the risk of pressure injury in inpatients in China.
