Study Overview
Brief Summary
Guided self-help (GSH) is a recommended first-step treatment for bulimia nervosa, binge eating disorder, and atypical variants of these disorders. The current study proposes to investigate the effectiveness of providing GSH either face-to-face or via e-mail, also using a delayed treatment control condition. Symptom outcomes will be assessed, and an estimate of cost-effectiveness made. Results are proposed to be disseminated locally and internationally (through submission to conferences and peer-reviewed journals), and will hopefully inform local service provision.
Please note that we are only able to offer the intervention to individuals who are currently registered with a General Practitioner that is covered by Oxford Health NHS Foundation Trust - this is typically restricted to practices in Oxfordshire, Buckinghamshire, and parts of Wiltshire.

Outcomes
Primary Outcomes
EDE-Q
Time Frame: Change in symptoms between Assessment, Start-of-treatment (approx. 3 months later), End-of-treatment (approx. 12 weeks after start of treatment), and 6-month follow-up
The EDE-Q is given as a measure of eating disorder symptoms in a standardised pack of measures, all given at Assessment, Start-of-treatment, End-of-treatment, and 6-month follow-up. "Assessment" concerns the patient's first contact with the Eating Disorders Service. Start-of-treatment will proceed as soon as possible; at present, the waiting list is around 3 months. Treatment lasts 12 weeks, so End-of-treatment measures will be given approximately 12 weeks after start of treatment. There is a 6-month follow-up. Binge eating is the primary outcome measure, with other eating disorder symptoms as secondary measures. Change in these symptoms will be assessed over the course of treatment.
