Abstract

Aim: The purpose of this study was to translate the Stoma-quality of life into Chinese and evaluate its psychometric properties in Chinese patients.

Background: Quality of life is an important issue for patients with colostomy, and its appropriate and precise measurement is beneficial to promoting better care. The Stoma-quality of life questionnaire has been widely used; however, the validity and reliability of its Chinese version has not been determined.

Design: A cross-sectional validation study was conducted.

Methods: We translated the Stoma-quality of life into Chinese using standardized methods. Then it was psychometrically tested on a convenience sample of 513 patients with colostomy. Construct validity was evaluated via exploratory factor analysis and confirmatory factor analysis. Reliability was measured with Cronbach's alpha and the split-half Spearman-Brown coefficient.

Results: The content validity, the Cronbach's α coefficient and the Spearman-Brown split-half reliability coefficient indicated adequate validity and reliability. The exploratory factor analysis yielded four common factors, and the cumulative variance contribution rate was 67.5%. Moreover, the confirmatory factor analysis showed a good model fit.

Conclusion: This study confirmed that the Chinese version of Stoma-quality of life is an effective and reliable measurement for evaluating the quality of life of patients with colostomy.

Keywords: colorectal neoplasms; nursing; quality of life; reliability and validity; surgical stomas.
