Abstract: Objective: To assess the validity and reliability of the Chinese version of the Incontinence-Associated Dermatitis and its Severity Instrument (IADS) among the Incontinence-Associated Dermatitis patients. Methods: The IADS was translated into Chinese and adapted to Chinese culture. Totally 100 Incontinence-Associated Dermatitis patients were investigated by the Chinese version of IADS and we tested the reliability and validity of the Chinese version of IADS. Results: The Chinese version of IADS consisted of 14 items and the content validity index was 0.930. Four factors were extracted by factor analysis and could explain 88.389% of the total variance. The criterion validity with Skin Assessment Tool (SAT) was 0.826. The Cronbach's α coefficient was 0.875 for the overall scale and 0.901~0.931 for the four factors. Conclusion: The Chinese version of IADS has acceptable reliability and validity. It can be used to measure the incontinence-associated skin damage of IAD patients in clinic.
