The aim of the study was to evaluate the psychometric properties of the Three Factor Eating Questionnaire (TFEQ-R18) in Mexican patients with obesity. Methods: 292 Mexican adults (194 women, 98 men) who entered a multidisciplinary treatment program for obesity at a third level hospital in Mexico, completed the TFEQ-R18 to obtain the psychometric properties. Results: The TFEQ-R18 has a good internal consistency showing a global Cronbach´s a= 0.88, and McDonald’s w=0.88, and maintained the original three factors (cognitive restraint, uncontrolled eating and emotional eating); CFA showed adequate goodness-of-fit indices, except for the X2 (X2 = 274.5, df = 142, p <.001; RMSEA = .061, CI [.051, .071]; CFI = .93; TLI = .92; SRMR = .071). There is a significant positive correlation with the diagnosis of eating disorder and emotional eating with uncontrolled eating and emotional eating factors. Conclusions: The TFEQ-R18 allows an adequate evaluation of the three eating factors in Mexican patients with obesity and allows a differentiation between cases with or without eating disorders.
