Eating Disorder Inventory-3 (EDI-3)
David M. Garner, Ph.D.
• Purpose: Assess a broad range of features common in eating disorders
• For females ages 13-53 years
• Administration for individual or group
• Time = 20 minutes
The revised EDI-3 is one of the most widely used self-report measures of psychological traits or constructs shown to be clinically relevant in individuals with eating disorders. This new version is a standardized and easily administered measure yielding objective scores and profiles that are useful in case conceptualization and treatment planning for individuals with a confirmed or suspected eating disorder. It is also a valuable research tool for assessing areas of psychopathology and treatment outcome.
The EDI-3 has been significantly enhanced to provide scales and composites for measuring constructs that are most consistent with the psychological domains identified as relevant to eating disorders by modern theories. The item set from the original EDI and EDI-2 revision have been carefully preserved so that clinicians and researchers can continue to compare data collected previously.
The EDI-3 consists of 91 items organized onto 12 primary scales, consisting of 3 eating-disorder-specific scales and 9 general psychological scales that are highly relevant to, but not specific to, eating disorders. It yields six composites: Eating Disorder Risk, Ineffectiveness, Interpersonal Problems, Affective Problems, Overcontrol, General Psychological Maladjustment.
EDI-3 Symptom Checklist (EDI-3 SC)
The EDI-3 SC is an independent and stuctured self-report form. This form is easy to complete and provides data regarding frequency of symptoms (i.e., binge-eating; self-induced vomiting; exercise patterns; use of laxatives, diet pills, and diuretics). Detailed information regarding the symptom areas assessed by the EDI-3 SC is necessary for determining whether patients meet the formal diagnostic criteria for an eating disorder.
New! EDI-3 Referral Form (EDI-3 RF)
The EDI-3 RF is an abbreviated form of the EDI-3 and includes the three scales that compose the Eating Disorder Risk Composite (i.e., Drive for Thinness, Bulimia, Body Dissatisfaction). In addition to the 25 EDI-3 questions, this brief self-report form includes behavioral symptom questions to identify individuals with potential eating disorders or pathology.
Administration / Scoring
The EDI-3 uses a 0-4 point scoring system that improves the reliabilities of some scales and yields a wider range of scores. The new, easy-to-use T-Score and Percentile Forms include critical item sets that allow for the development of a more meaningful clinical picture.
