EDI™-3

Reliability, Validity, & Norms

• Includes normative data for both adolescents and adults: U.S. adult clinical (N = 983) and international adult clinical (N = 662) groups consist of adults ages 18 years and older.
• U.S. adolescent clinical (N = 335) group includes adolescents ages 11 to 17 years.
• Features excellent reliability and validity.

Test structure

• The easy-to-use Percentile/T-Score Profile Forms include critical item sets that allow for the development of a more meaningful clinical picture.
• An independent and structured self-report form, the EDI-3 SC 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) necessary for determining whether patients meet DSM-IV-TR diagnostic criteria.
• The EDI-3 Referral Form (RF) is an abbreviated form for allied health professionals.
• Administration and scoring are available 24/7 on PARiConnect, our online assessment platform.
• The EDI-3 consists of 91 items organized into 12 primary scales: Drive for Thinness, Bulimia, Body Dissatisfaction, Low Self-Esteem, Personal Alienation, Interpersonal Insecurity, Interpersonal Alienation, Interoceptive Deficits, Emotional Dysregulation, Perfectionism, Asceticism, and Maturity Fears.
• Yields six composites: one that is eating-disorder specific (i.e., Eating Disorder Risk) and five that are general integrative psychological constructs (i.e., Ineffectiveness, Interpersonal Problems, Affective Problems, Overcontrol, General Psychological Maladjustment).
• The item set from the original EDI, as well as items from the 1991 revision (EDI-2), has been carefully preserved so that clinicians and researchers can compare data collected previously with data from the EDI-3.
