Objective The interrater reliability of the modified version of the widely used Morgan‐Russell Assessment Schedule was assessed. Method: Sixty‐six female patients presenting for treatment for the first time in a general hospital and a community health center were assessed by a treating clinician and a researcher during sequential interviews. Two extra items were added to the Schedule to allow for the assessment of bulimic behaviors. Ratings were analyzed using the Cohen's weighted kappa. Results: Poor to very poor levels of agreement were found between rater pairs assessing the 66 separate patients. Discussion: The necessity for a specific, standardized format in using the Morgan‐Russell Schedule is discussed. In its current, unstandardized format the Schedule may not be suitable for comparing outcome in eating disorders across different centers.
