The University of North Carolina at Chapel Hill is conducting a trial focusing on UCAN--Uniting Couples in the Treatment of Anorexia Nervosa. More information can be found at the link. I think this could be very beneficial as many times spouses, partners, significant others, etc. do not know how to help their loved one with an eating disorder. I think this could especially be helpful for the older eating disorder individual.
The one thing that boggles me about this is why this hasn't really been implemented sooner, or maybe it has just through family therapy? In any case, I hope it will just be another tool in the process of recovery.
The study is still open, so go to the link if you're interested.
