Abstract
Los pocos estudios realizados sobre las propiedades psicométricas del EATQR, todavía más escasos en la versión larga, señalan una estructura diferente de la original. El objetivo de este estudio es traducir y adaptar al catalán la versión larga del EATQ-R, estudiar su consistencia interna y validez factorial y analizar las diferencias de género y edad en el EATQ-R. Para ello se han administrado el EATQ-R a una muestra de 1481 alumnos de Enseñanza Secundaria Obligatoria de edades comprendidas entre 12 y 17 años. Una vez eliminados un total de 40 ítems, de los 86 que componen el EATQ-R, se ha obtenido un modelo corregido, con unos índices de ajuste aceptables, formado por 8 de los 11 factores originales.This journal is registered under a Creative Commons Attribution 4.0 International Public License.
