Development of the Maladaptive Eating Behavior Questionnaire after Bariatric Metabolic Surgery and test of its reliability and validity
摘要
Abstract
Objective To develop a scientifically sound and standardized Maladaptive Eating Behavior Questionnaire after Bariatric Metabolic Surgery(MEBQBS),and to test its reliability and validity,providing a reference for early identification of maladaptive eating behaviors in post-bariatric patients.Methods Guided by the conceptual model of maladaptive eating behaviors after bariatric-metabolic surgery,the dimensions and item pool for the scale were initially constructed through literature review,focus group discussions,and a pilot survey.Item analysis was used to select the scale items.A convenience sample of 324 patients after bariatric surgery who attended follow-up visits at Jiangsu Province Hospital from January to October 2024 was surveyed to verify the reliability and validity of the scale.Results The MEBQBS consisted of 53 items,covering four measurement domains and eight sub-domains,namely emotional eating(negative emotional eating and positive emotional eating sub-domains),grazing(unplanned,repeated small food intakes),food cravings(positive outcome expectations,emotional cravings,and food addiction sub-domains)and loss of control eating(emotional experience and behavior sub-domains).Exploratory factor analysis identified eight common factors,with a cumulative variance contribution rate of 69.54%.The overall Cronbach's α coefficient for the scale was 0.97,with a split-half reliability of 0.79.Confirmatory factor analysis showed a goodness-of-fit chi-square test of 1.87,a goodness-of-fit index(GFI)of 0.80,a normed fit index(NFI)of 0.88,an incremental fit index(IFI)of 0.94,a non-normed fit index(NNFI)of 0.93,a comparative fit index(CFI)of 0.94,and a root mean square error of approximation(RMSEA)of 0.05.The total score and domain scores of the MEBQBS were positively correlated with total score of the Three-Factor Eating Questionnaire(TFEQ)-R21(all P<0.01).Conclusion The MEBQBS demonstrates good reliability and validity and can provide a scientific tool for evaluating unhealthy eating behaviors in Chinese patients after bariatric surgery.关键词
