RESUMO
Background Anorexia nervosa (AN) is a severe psychiatric disorder. Family based therapy is the most appropriate treatment. In recent decades, a particular form multi-family therapy (MFT) has been used. Aim To provide an overview of the scientific evidence regarding MFT in adolescents with AN. Method Literature search using PubMed, PsycInfo and Web of Knowledge. Literature was searched about the treatment of AN in adolescents through multi-family therapy in day therapy setting. Seven studies were included: one RCT with a strong methodology, two smaller controlled studies and four case series. Results After completing MFT, clear significant improvement is reported in terms of weight or BMI and eating disorder symptoms. Two studies suggest MFT is more effective in accelerating weight gain and achieving weight recovery. Depressive features, individual and family factors also improve. The low drop-out rate is remarkable. Conclusion MFT as an additional treatment for adolescents with AN is promising. Based on the available evidence, a good and at least equivalent outcome in comparison with family therapy is expected. In addition, it offers several unique benefits.
