I don't know exactly how to go about determining it, but the facility must recognize that the eating disorder and its accompanying behaviors are a method of coping and the person's best attempt at dealing with life's stresses. Their goal in treatment should be to help the person identify their feelings and to help them develop alternative methods of coping that do not adversely affect their physical health and well-being. Any professional center will approach your friend's situation from this angle. The trick is to pick the center that's professional. Like I said, I don't know exactly how to go about doing that. Asking way too many questions is a great start.
