The authors, continuing to write about multifamily therapy (MFT), present the multifamily approach to the treatment of patients with eating disorders. This method of therapy, with simultaneous participation of several family systems that struggle with a disordered child, has been practiced since the 1980s but its intensive development occurred mostly in the last twenty years. The authors, drawing from several reports, point to the benefits of multifamily therapy as a method of treatment of anorexic teenagers. They present models of therapy that have been utilized by different clinical teams and present the results of clinical studies. Multi-family therapy for teenagers with anorexia seems to be as effective as traditional family therapy. Its advantage is that it actively uses resources of the participants and creates the context for rapid growth in families. Due to insufficient data, the discussed method of work requires further research on its effectiveness. The authors recommend incorporating this approach to eating disorder treatment programs that are already existing in Poland.
