Validity and reliability of the Chinese version of the Ostomy Leak Impact Tool

Purpose To translatethe ostomy leak impact tool and test its reliabilityand validity for providing an effective tool for brief and rapid clinical assessment of dietary behavior in ostomy patients. Methods The Chinese version of the ostomy leak impact tool was developed by Brislin's translation model for translation，back translation，cultural adaptation，and pilot investigation. Using convenience sampling method，133 ostomy patients who were admitted to the inpatient ward or ostomy clinic of a tertiary hospital in Changzhou from January to September 2024 were selected as the research participants to test thereliability and validity of the Chinese version of ostomy leak impact tool. Results The Chinese version of ostomy leak impact tool includes 3 dimensions, with a total of 22 items. The Cronbach's α coefficient of the scale is 0.934; the Cronbach's α coefficients of the dimensions are 0.899～0.951. The test-retest reliability was 0.884, the content validity index at the scale level was 0.960, and the content validity index at the item level ranged from 0.875 to 1.000. Totally 3 common factors were extracted through exploratory factor analysis, with a cumulative variance of 72.097% . Conclusions The Chinese version ofostomy leak impact tool has good reliability and validity，and it can be used as a tool to evaluate theostomy patients.
