Development, reliability and validity of pediatric pressure ulcer trigger tool / 中国实用护理杂志

ABSTRACT

Objective To develop the Pressure Ulcer trigger tool, and to test the reliability and validity of the tool. Methods The tool was developed based on the conceptual schema of pressure ulcer, literature analysis and nursing practices, the Pressure Ulcer trigger tool was developed totally 274 records from 193 children were used to test the reliability and validity of the Pressure Ulcer trigger tool. Results The Pressure Ulcer trigger tool consisted of 3 items. The Cronbach's α coefficient for the total scale was 0.826, and Cronbach's α coefficient of each factor ranged from 0.743 to 0.819. The intra-class correlation coefficient was 0.941. The content validity index was 0.945, the correlation coefficients among each item ranged from 0.434 to 0.524, and the coefficient between each item score and total score ranged from 0.703 to 0.870. Concurrent validity was indicated by high sensitivity (100%) and specificity (96.40%). Parallel validity test Kappa value was 0.819. Conclusion The Pressure Ulcer trigger tool showed excellent preliminary psychometric performance when used to assess risk of pressure ulcer in pediatric patients, while further researches are merited.
