Objectives The purpose of this study is to verify the validity and reliability of the Korean version of Weight Efficacy Life-Style Questionnaire (K-WEL), which has been cross-culturally translated and face validated. Methods In this study, 375 obesity patients who visited a Korean medicine clinic in Seoul participated and we examined the validity and reliability of the questionnaire via exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and internal reliability. Results The 20 questions on the K-WEL questionnaire were classified into 4 factors of 15 questions based on the results of EFA, and its root mean error of approximation, goodness of fit index, and comparative fit index was 0.06, 0.92, and 0.93, respectively, so the model fit met the criteria. As a result of CFA, K-WEL15 has low correlations between questions on the sub-factors and low independence between sub-factors, thus the construct validity was found to be low. In the reliability test, the Cronbach s α ranged from 0.71 to 0.83 for each factor, showed a reliable level. Conclusions K-WEL was found to be inappropriate for measuring eating self-efficacy. In future studies, it is necessary to further develop a questionnaire with high validity to be used for the treatment and management of obesity in Korea, by considering the socio-cultural background of Korean and the construction of self-efficacy.
