    BackgroundSelf-efficacy is a crucial variable that is related to quality of life. Patients who have high self-efficacy will exert sufficient effort and have better health outcomes and improved quality of life. Appropriate and precise measurement of self-efficacy can help promote better care. The Breast Cancer Survivor Self-efficacy Scale (BCSES) is designed to measure the perceived confidence of breast cancer patients in managing the tasks for self-management. Originally developed in America, it has not been used in China.ObjectivesThe aims of this study were to translate BCSES into Chinese and assess its psychometric properties among Chinese patients.MethodsIn phase 1, the translation of BCSES closely followed the Principles of Good Practices. In phase 2, data on reliability and validity were evaluated in terms of internal consistency, item-total correlations, test-retest reliability, criterion validity, and construct validity. A total sample of 630 native Chinese-speaking patients from 5 hospitals in China participated, including a pilot sample of 182 and a validation sample of 448.ResultsMinor modifications in 5 items were recommended after translation. Both exploratory and confirmatory factor analyses suggested a 2-factor structure was more ideal than the original 1-factor model. Cronbach's α coefficient for the Chinese version of BCSES was .82, intraclass correlation coefficient was 0.97, and item-total correlations were from 0.61 to 0.76.ConclusionsThe Chinese version of BCSES appears to be culturally appropriate, reliable, and valid for assessing self-efficacy among patients with breast cancer in China.Implication For PracticeThe Chinese version of BCSES could help measure the breast cancer patients' self-efficacy and provide evidence to develop culturally sensitive interventions for Chinese patients.
