TENORIO, Juliana Maria Vieira et al. Adaptation and validation of the Eating Disorder Inventory for the Brazilian context. Aval. psicol. [online]. 2021, vol.20, n.3, pp. 263-273. ISSN 1677-0471.  http://dx.doi.org/10.15689/ap.2021.2003.19890.01.

The aim of this study was to adapt and validate the Eating Disorder Inventory (EDI-3) for the Brazilian context. The EDI-3 contains 91 items and 12 subscales. A group of 664 people aged of 14 to 51 years (M=22.33; SD=5.63) participated in the study, 71 high school students and 512 university students and a clinical sample of 81 participants. Confirmatory factor analysis indicated that the Eating Disorder Risk Composite (EDRC) showed a three-factor structure with good fit indicators, while the General Psychological Maladjustment Composite (GPMC) showed better indicators in the four-factor model. Internal consistency was adequate for most subscales. Group comparisons showed complementary evidence of instrument reliability. The results indicate that this measure may be suitable for use in research and in the clinical evaluation scenario.
