Antisuicide Therapy May Help Bulimics Cope With Disease.


WebMD Health News

"Dialectical behavior therapy, or DBT, says that binge eating is a way of dealing with unbearable feelings," lead researcher Debra L. Safer, MD, tells WebMD. "It's a way of distracting oneself, it's a behavior that regulates [mood]. According to this therapy, an inability to self-soothe is at the core of bulimia."

DBT has been used increasingly for treating 'parasuicidal' behaviors like cutting or overdosing on sleeping pills, says Safer, a staff psychiatrist in the department of psychiatry and behavioral sciences at Stanford University School of Medicine. "These people hurt themselves to feel better, and there seems to be a direct analogy between those behaviors and binge eating. Bulimics are using food to avoid painful emotional states."

In fact, many bulimics report entering a detached, trancelike state while binging and purging. "But you can't progress through life if you blunt all your feelings," says Safer.

Her team assigned 31 bulimic women either to 20 weekly 50-minute dialectical behavior therapy sessions or to a 20-week "waiting period." All the women had had at least one binge/purge episode per week -- out-of-control eating followed by self-induced vomiting or laxative use -- during the previous 3 months. None were emaciated, severely depressed, undergoing another type of therapy, taking antidepressants, or actively abusing drugs or alcohol.

"In DBT, patients are not told that their feelings are wrong, but rather that they need to find a more positive way to manage them," says Safer. "They learn mindfulness -- stepping back and being conscious of the moment without judging it as good or bad -- and other emotion-regulating skills, so that their feelings have less influence on their behavior."

They also learn distress tolerance -- coping with situations as they are -- and methods of self-soothing and distraction, and they practice these skills until they replace the automatic binge/purge response.

After 20 weeks, four women in the DBT group had stopped binging and purging completely, while several others reported significant reductions in the frequency of binge/purse episodes. There was no improvement in the waiting group.

Other types of therapy for bulimia tend to focus on dieting and distorted body image. But in DBT, "emotions are primary," says Safer. "We don't even talk about food. For some reason, whether biological or environmental, [bulimics] don't have skills for dealing with their emotions. Food is used to create walls because they don't have a way to let what's going on outside be outside, while remaining calm inside.
