Zusammenfassung:This research examines the internal consistency, convergent validity, and sensitivity, specificity, and positive and negative predictive value of the Spanish version of the Eating Disorder Examination-Self-Report Questionnaire (S-EDE-Q), as a screening questionnaire for eating disorders (ED) in a community sample. Participants were 1543 male and female Spanish-speaking students (age range: 12-21 years), who volunteered to complete the S-EDE-Q and the EAT-40. The Spanish version of the Eating Disorders Examination (S-EDE) interview, 12th edition, was administered to 602 of the students. Acceptable internal consistency for the four subscales of the S-EDE-Q was obtained (α ≥ .74). Corrected pointbiserial correlation performed with the 22 items included in the S-EDE-Q subscales showed acceptable values for all the items. The EAT-40 Dieting subscale correlated highly and positively with the four S-EDE-Q subscales (r ≥ .70). Acceptable results in sensitivity, specificity, and positive and negative predictive value when compared with the EDE were found. Correlation between S-EDE and S-EDE-Q diagnoses was positive and significant. Overall, results support the psychometric adequacy of the S-EDE-Q as a screening questionnaire for ED in community samples. Este estudio examina la consistencia interna, validez convergente, y la sensibilidad, especificidad y valor predictivo positivo y negativo de la versión española del Eating Disorder Examination-Self-Report Questionnaire (EDE-Q), como cuestionario de screening de los trastornos de la conducta alimentaria (TCA) en una muestra comunitaria. Un total de 1543 estudiantes hispano-hablantes de 12 a 21 años de ambos géneros completaron la versión española del EDE-Q y el cuestionario EAT-40. La versión española de la edición 12 de la entrevista Eating Disorders Examination (EDE) fue administrada a 602 estudiantes. Se obtuvo aceptable consistencia interna para las cuatro subescalas de la versión española del EDE-Q (α ≥ .74). Correlación biserial puntual corregida realizada con los 22 ítems incluidos en las subescalas de la versión española del EDE-Q mostró valores aceptables para todos los ítems. La subescala Dieta del EAT-40 correlacionó positiva y significativamente con las cuatro subescalas de la versión española del EDE-Q (r ≥ .70). Resultados aceptables en sensibilidad, especificidad y valor predictivo positivo y negativo fueron hallados en comparación con la entrevista EDE. La correlación entre los diagnósticos obtenidos
