OBJECTIVE: The Eating Disorder Inventory-C (EDI-C) is a multidimensional self-report questionnaire for children and adolescents used to characterize differences in the symptoms of eating disorders. It is based on the EDI-2 questionnaire, which is designed for adults. Although the psychometric properties of the EDI and EDI-2 have been well characterized, no studies exist on the EDI-C. Thus, we aimed to establish the factor structure of the EDI-C questionnaire among children. METHOD: A nonclinical sample of 898 children aged 9-16 years completed the EDI-C questionnaire at school. RESULTS: Instead of the original 11-factor structure of the EDI-2, 5 factors with high reliability were extracted when 27 items with low communality were removed from analysis. DISCUSSION: When the EDI-C is used, the reliability of the original 11 factors may be low. A modified subscale structure with five factors is proposed. Copyright 2005 by Wiley Periodicals, Inc
