title: Efficacy of a brief group psychoeducational intervention for bulimia nervosa.
abstract: This study compared a brief group treatment that was designed to be purely educational (ED) with a longer course of individual cognitive-behavioural (CB) therapy intended to represent more standard clinical care. Participants were 65 women who sought treatment at Toronto General Hospital, met DSM-III criteria for bulimia nervosa at a normal weight and reported vomiting at least twice weekly. Results indicated that the CB treatment, as expected, was generally more effective than the ED intervention, but on several important outcome indices both treatments appeared to be equally effective for the healthiest 25-45% of the sample. The more intensive individual CB treatment was associated with greater improvement in patients who were more severely symptomatic. However, the ED intervention proved significantly more cost-effective and it was suggested that a sequential treatment program might achieve the superior benefits associated with the longer individual CB treatment at a reduced cost.
