Although eating disorders often occur during or after puberty, it is likely that critical antecedent conditions can be established before adolescence. The Eating Disorder Examination has been adapted for children and is described by Bryant - Waugh, Cooper, Taylor and Lask (1996). The EDE is considered the gold standard of measures of eating disorder psychopathology (Wilson, 1993), and this adaptation, which allows its use with a younger age group, is a potentially important addition to the assessment of eating disorders in children. The latest version of EDE, the l7th edition, has now surpassed its predecessors.

The aim of the study is to evaluate the psychometric properties of the Child vers ion EDE (chEDE) translated into Italian, in a sample of patients with eating disorder
