Objetive: to establish validity and reproductibility of eating disorders autoreport screening questionnaire (EDQ) in universitary students. Methods: Elaboration and testing of an diagnostic EDQ in patients and universitary students; it was validated by structured interview for eating disorders (E.D). Results: the EDQ scored 3 23 in patiensts with E.D. The 31 questions were significatively correlated (Cronbach a) to global score with and without each Ítem in the sample and subsamples (n=482). Test-Retestfiability correlation in global score was good (n=159, r=0.91) without differences by sex. A 90.5% to 94.5% and 74.5% a 80% sensibility and specificity respectively were observed for subsamples and total sample; predictive positive valué was between 91% and 94%. Conclusions: The EDQ is an screening autoreport for E.D with internal and external validity; its reproductibility and utility is good and probably can cand be used for E.D diagnoses.
