Clinical cutoff scores for self-report measures provide a means of evaluating clinically significant pathology during and after treatment. A cutoff of 2.8 on the Eating Disorder Examination-Questionnaire (EDE-Q) has been recommended to screen for eating disorders (ED). We used this cutoff to assess ED symptoms in adolescents ( n  = 444) and adults ( n  = 592) through ED treatment and follow-up. Most patients scored above 2.8 at intake (adolescents 67%, M  = 3.21; adults 78%, M  = 4.20) and below 2.8 at discharge (adolescents 65%, M  = 1.87; adults 66%, M  = 2.67), with gains often maintained through follow-up (40% of adolescents and 35% of adults at 12-month follow-up). EDE-Q scores were higher in adults than adolescents and in patients with binge/purge disorders. Results suggest a cutoff of 2.8 on the EDE-Q effectively tracks ED symptom improvement through treatment and discharge. This supports the need for the development of culture-specific and empirically developed clinical cutoffs and their widespread use to evaluate program effectiveness.
