OBJECTIVE: To evaluate the psychometric properties of the Mexican version of the Eating Attitudes Test (EAT-40) in clinical and control populations in Mexico City. METHOD: 276 female patients with eating disorders [52 with anorexia nervosa (AN), 102 with bulimia nervosa (BN) and 122 with eating disorders not otherwise specified (EDNOS)] and a comparison group of 280 normal control female subjects completed the EAT. RESULTS: The EAT had an adequate level of internal consistency in the clinical sample (Cronbach's alpha=0.90). Total score was significantly correlated with criterion group membership (r=0.77, p< or =0.0001), suggesting a high level of concurrent validity. There was a small overlap in the frequency distribution of the 2 groups (eating disorders and control) and only 6% of the normal controls scored as high as lowest anorexic and bulimic patients. The factorial analysis yielded five factors accounting for 46.6% of total variance: 1) Dietary restraint, 2) Bulimia, 3) Drive of thinness, 4) Food preoccupation and 5) Perceived social pressure. CONCLUSIONS: This study provides evidence that the Mexican version of the EAT is an economical, reliable and potentially useful instrument for research in this field.
