Objective To translate Bariatric Surgery Self-management Questionnaire（BSSQ） into Chinese，and to test its reliability and validity. Methods After obtaining the authorization of the author of the original questionnaire，the original questionnaire was first forward translated，synthesized and translated back，and then the Chinese version of the BSSQ was formed after the cultural adjustment（2 rounds of expert consultations and the pre-test）. From May to August 2022，a convenience sample of 227 patients undergoing metabolic bariatric surgery who were followed up in the outpatient department of metabolic bariatric surgery of a tertiary A general hospital in Shenyang as the study subjects were investigated，and 30 patients were conveniently selected for retest after 14 days to evaluate the reliability and validity of the questionnaire. Results The Chinese version of BSSQ includes 9 dimensions with a total of 32 items. The content validity index of each item is between 0.833 and 1，and the content validity index of the total scale is 0.970. Exploratory factor analysis resulted in a 9-factor structure，explaining 60.314% of the total variance. The score of Chinese version of BSSQ was positively correlated with GSES score（r=0.329，P<0.001） and negatively correlated with PHQ-9 score（r=-0.141，P=0.034）. The Cronbach’s α coefficient for the total BSSQ score was 0.867，and 0.420~0.813 for each factor. The retest reliability for the total BSSQ score was 0.885，and 0.766~0.982 for each factor. Conclusion The Chinese version of BSSQ has good reliability and validity，and it can be used as a tool to evaluate self-management ability of patients undergoing metabolic bariatric surgery in China.
