Eating Disorder Inventory (EDI-2): Normative data among 10 to 20 year old German girls and boys

The Eating Disorder Inventory-2 (EDI-2; Paul & Thiel, 2005) is a multidimensional psychometric self-report instrument for assessing disordered eating behavior and associated psychological characteristics among patients with anorexia (AN) and bulimia nervosa (BN). To enhance the clinical and research utility of the EDI-2 for children and adolescents, we report normative data among 1,754 German participants aged 10 to 20 years (Mean age = 15.8, SD = 1.7). Additionally preliminary results of 66 patients with AN (Mean age = 16.2, SD = 1.7) and 22 patients with BN (Mean age = 16.8, SD = 1.5) are presented. Results indicate that female patients with AN display higher scores on most of the EDI-2 subscales (except bulimia, maturity fears, and impulse regulation) and on the EDI-2 total score than female healthy controls. The presented normative data of children and adolescents aged 10 to 20 years and the psychometric analysis we reported elsewhere (Salbach-Andrae et al., 2010) allow international gender-specific and age-specific (for female samples) comparisons.
