BMI was lower in patients with major depressive disorder (44.9 ± 7.89) than in subjects without mood disorders (46.75 ± 7.99, p  = 0.017). Bariatric patients show high rates of psychiatric disorders, especially binge eating and mood disorders. Longitudinal studies are needed to explore the possible influence of such comorbidities on the long-term outcome after bariatric surgery. V, cross sectional descriptive study. V, cross sectional descriptive study. The aim of this study was to provide preliminary psychometric evidence for the Chinese version of the Inflexible Eating Questionnaire (C-IEQ) among a large sample of Chinese adolescents. For testing the psychometric properties of the C-IEQ, a total of 2241 (M  = 13.91years; 46.4% boys) adolescents from mainland China responded to the survey. Confirmatory factor analysis (CFA) was used to examine the factor structure of the C-IEQ. Measurement invariance by gender was examined by both multi-group CFA and differential item functioning (DIF). Convergentvalidity of the C-IEQ was assessed via examining the correlations between the C-IEQ scores and theoretically related constructs (e.g., orthorexia nervosa symptomatology, eating disorder symptomatology, and body image inflexibility). The unidimensional structure with correlated errors of the C-IEQ showed good model fit (χ  = 1674.05, df = 44, p < 0.001; CFI = 0.93; TLI = 0.91; RMSEA = 0.13; SRMR = 0.06). The C-IEQ had an adequate internal consistency (α = 0.89) and demonstrated strong measurement invariance across genders. Moreover, the scores of the C-IEQ showed significant correlations with theoretically correlated constructs orthorexia nervosa symptomatology (girls; r = 0.53 p < 0.001, boys; r = 0.45 p < 0.001), eating disorder symptomatology (girls; r = 0.32 p < 0.001, boys; r = 0
