Multifamily therapy (MFT) for adolescent eating disorders (ED) is anchored in systemic theory and family therapy, but two conceptual and practical paths have emerged from this common framework. The first one, called ED‐focused MFT, is centered on behavioral change and weight gain in the early stages of treatment, while the second, known as relationship‐focused MFT, is less directly focused on symptom improvement and more on family changes. Compared to ED‐focused MFT, validation of more relationship‐focused MFT models has been lagging behind although they are frequently implemented and practiced in Europe. The purpose of this article is to give more visibility to existing relationship‐focused MFT models by presenting an integrative, yet predominantly family‐oriented MFT program developed for adolescent anorexia nervosa (AN) (12 to 18 years) on the ED unit of a large pediatric hospital in France. After presenting the history and development of this relationship‐focused MFT program, including the challenges it encountered and its evaluation, we describe its rationale and objectives, then outline its course and content, giving illustrations of techniques and activities for each of the five phases of the program. Finally, we review the current status of this model, its advantages and limitations, and provide a critical appraisal of existing evidence and recommended future research directions.
