Multi-family therapy for bulimia nervosa: a qualitative pilot study of adolescent and family members' experiences.

Background: Multi-family therapy (MFT-BN) is a new treatment for adolescent bulimia nervosa with emerging empirical support. It extends the bulimia nervosa focussed family therapy model, by offering treatment in a group setting. Up to nine families work together with a team of clinicians over the course of 20 weeks.
