*Research Study using MRI to examine Bulimia Nervosa in Adolescent Girls - Participants Needed!

Researchers at Columbia University Medical Center are conducting an NIMH-funded study aimed at understanding brain development in adolescents with Bulimia Nervosa. We are looking for girls, 12-18 years old, who binge-eat and purge. Participation involves completing interviews, games and puzzles, and an MRI scan. Treatment, free of charge will be provided to girls in need. Compensation (up to $400) will also be provided for participation. The study takes place at the New York State Psychiatric Institute, 1051 Riverside Drive in Manhattan.
