title: Validating the EDI-2 in three Swedish female samples: eating disorders patients, psychiatric outpatients and normal controls.
abstract: The aim of the current study was to validate the Eating Disorders Inventory 2 (EDI-2) in a Swedish population by investigating how it discriminates between three female samples aged 18 to 50 years: patients with eating disorders (n = 978), psychiatric outpatients (n = 106) and normal controls (n = 602), as well as between different eating disorder diagnoses. The internal consistency of the EDI-2 was above 0.70 for most subscales. The EDI-2 discriminated well between patients with eating disorders and normal controls on all subscales. On the symptom-related subscales, eating disorder patients scored highest followed by psychiatric controls and normals. All subscales except Perfectionism, Interoceptive awareness and Asceticism discriminated eating disorder patients and psychiatric controls. Bulimia patients scored higher than anorexics on the symptom subscales. It is concluded that the EDI-2 discriminates well between eating disorder patients and both psychiatric and normal controls.
