Assessing implementation fidelity in the First Episode Rapid Early Intervention for Eating Disorders service model

Background The First Episode Rapid Early Intervention for Eating Disorders (FREED) service model is associated with significant reductions in wait times and improved clinical outcomes for emerging adults with recent-onset eating disorders.
