International comparison of physicians' attitudes toward refusal of treatment by patients with anorexia nervosa: a case-based vignette study.

Physicians in all three countries tended to choose compulsory treatment irrespective of disease duration or whether the patient's family requested treatment or not. This may indicate that medical practitioners value the ethical obligation of beneficence, giving priority to the protection of life. Attitudes toward refusal of treatment during a life crisis tend to vary among medical professionals, particularly if the patient's family does not request treatment.
