According to the National Center for Excellence in Eating Disorders (NCEED):
CBT-E is one of the leading evidence-based treatments for eating disorders, including anorexia nervosa, bulimia nervosa, binge-eating disorder, and other similar states.
CBT-E was originally developed as an outpatient treatment for adults. A version of the treatment is available for younger people, and it is also available as an intensive form for day patients and inpatients. It is a highly individualized treatment that focuses on the factors that maintain the disorder, with the therapist creating a version of CBT-E to match the eating problems of the person receiving treatment.
