Normative data for measures of eating disorder (ED) psychopathology provide a fundamental description of a presentation and a means to establish clinically significant change following an intervention. Clinical norms for the ED population are lacking and out of date following the publication of Diagnostic and Statistical Manual of Mental Health Disorders (DSM) 5. This study aimed to show that scores from the Eating Disorder Examination Questionnaire (EDE-q) and the Eating Disorder Inventory (EDI) differ across ED diagnosis groups and provide norm data for DSM-5 ED diagnoses. Patients (n=932) presenting to an out-patient service over 5years were retrospectively re-diagnosed based on DSM-5 criteria. Statistical analysis showed a significant difference on most subscale scores of the EDE-q and the EDI across diagnosis. Means, standard deviations and percentile ranks are presented by diagnosis. The norms detailed contribute to improving the accuracy with which scores are interpreted when using DSM-5 and aid with the assessment of clinically significant change following treatment.
