Objective This study aimed to evaluate the psychometrics of the Rating of Eating Disorder Severity Interview for Children (REDS‐C) and compare it with the Eating Disorder Inventory‐2 symptom index. Methods The psychometrics of the REDS‐C were analyzed utilizing data from 336 patients, of ages 8 to 18 years. Receiver operator curve analyses were performed to evaluate the ability of the REDS‐C and the Eating Disorder Inventory‐2 symptom index to discriminate severity of eating disorder symptoms in relationship to an objective standard, defined as hospitalisation for medical stabilisation beyond 1 week. Results Three factors were identified using 14 of the 16 original REDS‐C items. Resulting subscales demonstrated acceptable reliability and validity. The receiver operator curve results demonstrated the usefulness of the 14‐item version of the REDS‐C in predicting hospitalisation greater than 7 days as an indicator of symptom severity. Discussion The 14‐item REDS‐C is a reliable tool to assist clinicians in evaluating the severity of eating disorder symptoms in children and adolescents.
