Psychotherapy for bulimia: a controlled study.

A psychotherapy study for bulimia is described. The preliminary results of a random allocation control trial comparing cognitive behaviour therapy, behaviour therapy and group psychotherapy with a waiting list control are presented. The results of the first 60 subjects in active treatment are shown. They indicate that all three treatments are effective in dramatically reducing the behavioural symptoms of the bulimia syndrome. There is evidence that cognitive therapy has a greater effect on symptoms of depression and self-esteem. No evidence is yet available on the longterm outcome of the three treatments.
