Carer burden in eating disorders is considerable, but to date no research has examined carer burden from the perspective of the person with an eating disorder. The current brief report assessed carer burden with a short questionnaire, as perceived by 20 matched pairs of sufferers and their carers. Those with an eating disorder significantly underestimated the overall burden experienced by their carer, particularly in relation to nutritional difficulties and conflict within the family. Domains where carers and sufferers had high agreement may be useful in facilitating collaborative involvement between sufferers and carers in treatment, such as multi-family therapy.
