Synthesis of the Eating Disorder Inventory‐Third Edition (EDI‐3) psychometric characteristics: Implications for counseling practice and research

Abstract

AbstractAuthors reviewed 129 studies published between 2004 and 2020 using the Eating Disorder Inventory‐Third Edition (EDI‐3). Internal consistency (α) for the total score was 0.888 and 0.693–0.947 across all subscales. Convergent validity yielded robust, mostly large correlations for the three main scales, spanning five eating disorder instruments. Structural validity studies supported important EDI‐3 components for White women, but not for racial/ethnic minorities. Only one diagnostic validity study was located, and given that the EDI‐3 is used to help screen for and identify eating disorders, more diagnostic validity studies are needed. Implications for client outcome assessment, screening, and treatment planning were discussed.
