This is the official practice guideline for the treatment of patients with Eating Disorders developed and endorsed by the American Psychiatric Association. The guideline provides recommendations on assessment, monitoring, and implementation of a treatment plan. The guidelines are widely used internationally to assist psychiatrists, psychologists, and allied health professional's care for individuals with Eating Disorders. The guideline uses a level of evidence scheme based upon the degree of clinical confidence assigned to recommendations, and was constructed by a work group of psychiatrists with experience in the field of Eating Disorders with invited input from key stakeholders.
