Part of the research on eating disorders (ED) has focused on experimental presentation of thin ideal, with different stimuli (Groesz, et al., 2002); however, these rarely have been subjected to validation processes. Therefore, this study has aimed the content validity of an image catalog of thin, average weight and obese women. Participated 8 women who were called "Expert Judges" on ED and 30 female students aged 19 to 25 who were called "Non Expert Judges". We performed a search online of free images of women in three weight categories: thin, average weight and obesity. Of this search resulted 150 images which were edited. Subsequently images were randomized in slides to be categorized by judges in thin, average weight and obesity. We calculated the kappa index to find agreement among Expert Judges, this revealed adequate level of agreement (kappa = 0.7 to 0.76, p < 0.05). Then it was performed an analysis of agreement between Expert and Non Expert Judges, we obtained 32 Thinness, 38 Obesity and 12 Average weight images with an agreement percentage of 70 to 100%. The content validity of this catalog is an approach of the experimental presentation of stimuli that represents the thin ideal.
