Forty years of progress in the treatment of the eating disorders.

This paper reviews progress in the treatment of the eating disorders between 1968 and 2008. In 1968, no evidence-based treatments were available for any of the eating disorders, and binge eating disorder had not yet been described. In 2008, there are still no evidence-based treatments for anorexia nervosa, although a specific form of family therapy (based on the Maudsley model) appears promising. Both psychotherapeutic and psychopharmacological evidence-based treatments are now available for bulimia nervosa and binge eating disorder. Therapist-assisted self-help is a promising approach to treatment because it may reduce the costs of treatment, allow for more adequate dissemination to areas lacking specialty resources and also provide a basis for algorithm-driven approaches to treatment.
