Validation of Eating Disorder Examination Questionnaire (EDE-Q) -Spanish Version- for Screening Eating Disorders

Article excerpt

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 SEDE- 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-EDEQ diagnoses was positive and significant. Overall, results support the psychometric adequacy of the SEDE- 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 EDEQ (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 por las versiones españolas de la EDE y del EDE-Q fue positiva and significativa. Los resultados demuestran la adecuidad de la versión española del EDE-Q como cuestionario de screening de TCA en muestras comunitarias.

It is generally recognized that the administration of a structured or semistructured interview by clinicians or trained interviewers is the "gold standard" for the assessment of the specific psychopathology of eating-disordered behavior (Crowther & Sherwood, 1997; Fairburn & Beglin, 1994; Garner, 2002; Wilson & Smith, 1989). Frequently, however, clinicians and researchers need a more costeffective means of screening individuals. Because of the low prevalence of ED, it is usually not possible to conduct interview assessments with the total sample in ED epidemiological studies. Therefore, the use of a two-phase design, in which interview assessment is conducted only with probable cases identified on the basis of a self-report measure, is the most commonly used strategy in ED epidemiological studies (Dunn, Pickles, Tansella, & Vazquez-Barquero, 1999).

Among self-report measures of eating-disordered behavior, the Eating Attitudes Test (EAT; Garner & Garfinkel, 1979) has been widely employed as a screening questionnaire in ED epidemiological studies (Mond, Hay, Rodgers, Owen, & Beumont, 2004). …
