This chapter outlines the rationale, structure, and procedures of intensive outpatient CBT-E, a treatment developed for adolescents who require a more structured intervention than standard outpatient CBT-E but whose clinical condition does not warrant day-hospital or inpatient care. The program was specifically designed to address challenges that often hinder progress in standard outpatient CBT-E, while allowing patients to remain within their home environment and continue working with their outpatient team, thus avoiding the disruption commonly associated with day-hospital or inpatient treatment. Once these challenges have been resolved, patients can transition back to conventional outpatient CBT-E. The program is delivered in an outpatient-adapted clinical setting that, in addition to standard therapy rooms, includes practical facilities such as a kitchen, a dining area for assisted meals, a recreation space, and study areas to accommodate schoolwork. The treatment retains the core principles of CBT-E while incorporating additional strategies to address barriers such as persistent undereating, difficulty achieving weight restoration, and ongoing binge–purge behaviours. Delivered by a dedicated multidisciplinary team—including a psychologist, dietitian, and physician—trained in CBT-E, the program integrates individual CBT-E sessions, dietary consultations, medical monitoring, and assisted eating to address disordered eating in real time. Parents participate through structured sessions designed to support meals at home and foster a balanced home environment. Additional procedures focus on relapse prevention by maintaining progress outside the unit, reducing the risk of relapse associated with abrupt hospital discharge, and ensuring continuity of care.
