Guided Self-help for Binge Eating

March 31, 2017 updated by: Oxford Health NHS Foundation Trust

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.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Self-help
In this condition, participants complete a self-help intervention with the support of a therapist. This lasts 12 weeks.
Participants in this arm will receive face-to-face self-help; that is, self-help with the support of a therapist, attending the clinic in person.
Participants in this arm will receive e-mail self-help; that is, self-help with the support of a therapist, provided via e-mail.
Other: Waiting List
One third of participants will be allocated to a treatment waiting list, after which they will be randomised to one of the other two arms.
Waiting list condition - participants assigned to a waiting list (no intervention) condition

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.

Secondary Outcome Measures

Measure Description
Time Frame
CORE-OM
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 CORE-OM is given as a measure of psychological distress 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.

RSES
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 RSES is given as a measure of self-esteem 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.

CIA
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 CIA is given as a measure of psychological functioning (quality of life) 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.

HAq-II
Time Frame: End of Session 3 of treatment (3 weeks into treatment)
The Helping Alliance Questionnaire is given as a measure of therapeutic alliance after Session 3 of treatment (after 3 weeks from start of treatment) and again at end-of-treatment.
End of Session 3 of treatment (3 weeks into treatment)
Healthcare Use
Time Frame: Change in healthcare use between Start-of-treatment (approx. 3 months later), End-of-treatment (approx. 12 weeks after start of treatment), and 6-month follow-up
A measure of healthcare use was developed for the study and is given at Start-of-treatment, End-of-treatment, and 6-month follow-up. Start-of-treatment will proceed as soon as possible after assessment; 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.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Therapist Time
Time Frame: After every contact with the patient (approx. weekly), including weekly sessions during treatment (12 weeks)
Therapists are asked to indicate (to the nearest 5 minutes) how much time they spend doing clinical / administrative tasks for each patient (patient name not included). Although there are no formal guidelines for how therapists report their time, it should accurately record all contact with patients, and thus is suggested to be completed approximately weekly.
