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. © 2005 by Wiley Periodicals, Inc.
