Research suggests that Cognitive Behavioral Theraphy (CBT) provides the best immediate and long-term outcomes in the treatment of bulimia nervosa. It is a type of psychotherapy that is based on the scientific method and enjoys wide acceptance among professionals. It is a way of understanding how someone thinks about themselves, other people and about the world around them, and how what they do affects their thoughts and feelings. CBT can help them change the way they think ("cognitive") and how they act ("behavioral") and these changes can help them feel better. Unlike some of the other "spoken therapies," CBT focuses on problems and difficulties of the "here and now". Instead of focusing on the causes of distress or symptoms in the past, look for ways to improve their mood now.
