This a pseudo-randomized clinical trial that examines if a specific group therapy for BN is effective in improving its symptomatology, and what variables mediate such improvements. To do so a sample of 100 patients with BN will be pseudorandomized in a Group Therapy for BN or in a control waiting list group. Patients will be assessed at baseline, at the end of the group therapy and at 2 year follow up.
