Purpose The goal of the Eating Disorder Inventory-3 (EDI-3) is to provide a comprehensive measure for assessing individuals with a confirmed or suspected eating disorder. In addition, the EDI-3 is useful in evaluating areas of behavioral and psychological dysfunction as well as assessing treatment outcomes. David M.

This test can be administered to a group or individually and has an administration time of 20 minutes with an additional 20 minute scoring
