BackgroundThere is great potential demand for treatment of bulimia nervosa and binge eating disorder. Skilled therapists are in short supply. Self-help and guided self-help based upon books have shown some promise as an economical alternative to full therapy in some cases.AimsTo investigate the efficacy and effectiveness of self-help with and without guidance in a specialist secondary service.MethodA randomised controlled trial comparing three forms of self-help over 4 months with a waiting-list comparison group and measurement of service consumption over the subsequent 8 months.ResultsSelf-help delivered with four sessions of face-to-face guidance led to improved outcome over 4 months. There is also some evidence to support the use of telephone guidance. A minority of participants achieved lasting remission of their disorder in relation to self-help, but there was no significant difference in final outcome between the groups after they had progressed through the stepped care programme. Patients initially offered guided self-help had a lower long-term drop-out rate.ConclusionsGuided self-help is a worthwhile initial response to bulimia nervosa and binge eating disorder. It is a treatment that could be delivered in primary care and in other non-specialist settings.
