Aims:
To assess the validity and reliability of the stoma self-efficacy scale for Turkish-speaking individuals with stoma.
Background:
Self-efficacy in stoma care is one of the most important variables requiring compliance for an increase in the quality of life and well-being of individuals with stoma.
Design:
A methodological study.
Methods:
This study used translation and back translation for the scale's language equivalence and expert opinion for the content validity. An expert panel and 10 individuals with stoma evaluated the scale for face validity. The scale's reliability was assessed by internal consistency, Pearson correlation, and test-retest reliability in a sample of 174 individuals with stomas. The scale's construct validity was tested with confirmatory factor analysis and exploratory factor analysis.
Results:
The content validity index was .96, and Cronbach's alpha was .95. In the test-retest analysis, the intraclass correlation coefficients were high. In the factor analysis, two factors emerged from the scale, and after the confirmatory factor analysis and scale modification, the fit indices of the model were found to provide a good level of validity.
Conclusion:
The Turkish version of the stoma self-efficacy scale is a valid and reliable tool to determine the levels of self-efficacy in individuals with stoma.

Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
