Participants in this open-label study will be assigned to receive either treatment-as-usual (TAU) or NOE. Participants admitted to the study in the first 8 months of the trial will receive TAU. Those admitted after the first 8 months will take part in the NOE program. Participants may begin receiving treatment as soon as they enter the study and will continue receiving their assigned treatments for 6 weeks. All participants in the NOE group will be required to report to the study site three evenings a week. They will receive individual therapy, as well as take part in group and family therapy sessions. In addition, they will be supervised while eating a meal. Body weight, results of the Eating Disorders Examination and the Structured Clinical Interview for DSM-IV Axis I disorders, and self-report measures will be assessed post-treatment and at the Month 6 follow-up visit.
