Identifying duration criteria for eating‐disorder remission and recovery through intensive modeling of longitudinal data

Abstract

We recommend that 6 months be used for remission definitions applied to binge eating, purging, and BN symptom composite measures, whereas no duration criteria be used for low weight and AN symptom composites. We further recommend that 6 months be used for recovery definitions applied to BN symptom composites and AN symptom composites, whereas 18 months be used for individual symptoms of binge eating, purging, and low weight. The adoption of these duration criteria into comprehensive definitions of remission and recovery will increase their predictive validity, which in turn, maximizes their utility.
