The aim of this study was to validate the instrument Body Shape Questionnaire (BSQ) in female Mexican population, created to assess body dissatisfaction. 472 women participated, 256 were students and formed the control group (x‾ = 15.9, DE = 3.2) and 216 patients with Eating Disorders (ED) (x‾ = 20.5, DE = 3.9) with an age range of 13 to 30 years. The results showed excellent internal consistency (a = .98) and a 2-factor structure that explained 63.8% of the total variance. These were: 1) normative body uncomfort (α=.95), and 2) pathological body uncomfort (α=.94). Regarding the discriminant and predictive validity, the BSQ showed good ability to classify individuals with eating disorders, depending on body dissatisfaction, noting that such capacity is greater when discriminating between Anorexia, Bulimia and control (λ de Wilks = .485, χ²(gl=1)= 278.830, p≤ .001). Finally we explored 6 different cut off points, of which the 110-was proved to be the most appropriate according to their values of sensitivity (84.3%) and specificity (84.4%). In conclusion, the BSQ is a useful questionnaire to detect body dissatisfaction in Mexican women.
