Background and study aims
Eating disorders are a group of common conditions which are defined by an abnormal attitude towards food. Anyone can develop and eating disorder although they are far more common in women, particularly those who are in early adulthood. Bulimia nervosa is a serious mental health condition in which a person excessively overeats (binging) and then takes action to remove the food from the body quickly, such as by vomiting or using laxatives (purging). Binge eating disorder also involves binging but lacks the purging element, making it a very different disorder. It can take time for patients affected by these disorders to receive therapy, and so self-help programs could help to bridge this time gap. Self-help programs might be used as first step of treatment or to bridge waiting time for face-to-face outpatient treatment. It is unclear however, how this type of treatment could affect later outpatient therapy and whether it leads to a faster reduction of bulimic symptoms. The everyBody-Plus program is a treatment based on cognitive behavioural therapy (a type of therapy that aims to change the way people think and behave). It involves education about different aspects of eating disorders as well as self-monitoring, a personal journal and behavioural exercises. The aim of this study is to find out whether the everyBody-Plus program can help to reduce eating disorder symptoms and stop sufferers from binging and purging while they await outpatient therapy.

Who can participate?
Women who are seeking treatment for bulimia, binge eating disorder or other specified feeding or eating disorder (OSFED).

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive the everyBody-Plus program. This consists of eight weekly sessions that cover topics relating to eating and exercise patterns, coping with stress, improving body image and binge eating/purging. The participants are also asked to keep a journal and monitor their eating disorder symptoms, which they will receive weekly, personal feedback on. Those in the second group do not take part in any additional treatment during the wait for outpatient therapy, however they are also asked to monitor their eating disorder symptoms and keep a journal. At the start of the study, after the program ends and then six and 12 months later, participants in both groups complete a number of questionnaires in order to assess their eating disorder symptoms. The amount of time from the start of the study until patients show a clinical improvement (i.e. not binging/purging for at least four weeks and having a healthy weight) is also recorded for all participants.

What are the possible benefits and risks of participating?
Participants will benefit from being awarded points for each completed assessment which they are able to redeem for rewards. There are no direct risks to participants taking part in this study.

Where is the study run from?
1. Technical University Dresden (Germany)

Scientific titleUsing Internet-based self-help to bridge waiting time for face-to-face outpatient treatment for Bulimia Nervosa, Binge Eating Disorder and Other Specified Feeding and Eating Disorders (OSFED)
Study objectiveseveryBody-Plus will be associated with both a more rapid reduction of core eating disorder symptoms and higher abstinence rates compared with the waiting list group.

InterventionParticipants are randomly allocated to one of two groups.

Intervention group: Participants will receive everyBody Plus, based on eating disorder-specific cognitive-behavioural therapy. It consists of 8 weekly sessions and includes reading assignments, self-monitoring, a personal journal and behavioural exercises. Topics covered are healthy eating and exercise patterns, dealing with “forbidden foods” and binge eating/purging, improving body image, coping with stress and negative emotions, and self-esteem. Patients will receive weekly personal feedback based on their self-monitoring and journal entries. The program is supplemented by a moderated asynchronous discussion board to exchange experiences and thoughts with other patients. Trained clinical psychologists supervised by the study PIs will provide personal feedback and moderate the online discussion board. Further assessments will take place at post-intervention, 6- and 12-month follow-up. The Internet-based and therefore site-independent intervention will be guided by staff at TU Dresden (German version) and King’s College London (English version).

Control group: Participants will only be prompted to complete the weekly self-monitoring of core ED symptoms as well as the post- and follow-up assessments.
Intervention typeBehavioural
Primary outcome measureNumber of weeks after randomisation until a patient achieves a clinical relevant improvement* in core symptoms for the first time will be measured using a weekly symptom monitoring that includes questions about the number of binge eating and compensatory behaviours (vomiting, fasting, excessive exercise, use of laxatives, diuretics or appetite suppressants) and the current body weight of the participant.

*Clinically relevant improvement is defined as abstinence from binge eating and compensatory behaviours (vomiting, fasting, excessive exercise, use of laxatives, diuretics or appetite suppressants) and a BMI of over 18.5, over a period of at least four weeks. Weekly symptom monitoring continues until 12 months post randomisation.
Secondary outcome measures1. Number of therapy sessions after randomisation until a participant achieves a clinical relevant improvement for the first time. To obtain this information, cooperating therapists will be asked to provide information about the number of therapy session utilized by the participant once per quarter.
2. Frequencies of core eating disorder symptoms (i.e., binge eating, compensatory behaviours) in the previous month will be measured by self-report at baseline, post-intervention, 6 and 12 months follow up
3. Eating disorder psychopathology will be measured using the Eating Disorder Examination Questionnaire (EDE-Q) at baseline, post intervention, 6 and 12 months follow up
4. Body image concerns will be measured using the Weight Concerns Scale (WCS) at baseline, post intervention, 6 and 12 months follow up
5. Intuitive Eating will be measured using the Intuitive Eating Scale (IES) at baseline, post intervention, 6 and 12 months follow up
6. Fruit- and vegetable consumption will be measures by self-report at baseline, post-intervention, 6 and 12 months follow up
7. Depression will be measured using the PHQ-9 at baseline, post intervention, 6 and 12 months follow up
8. Anxiety will be measured using the GAD-7 at baseline, post intervention, 6 and 12 months follow up
9. Alcohol consumption will be measures using the The Alcohol Use Disorders Identification Test (AUDIT-C) at baseline, post intervention, 6 and 12 months follow up
10. Quality of life will be measured by the Assessment of Quality of Life-8D (AQoL-8D) questionnaire at baseline, post intervention, 6 and 12 months follow up
11. Self-Esteem will be measured using the Rosenberg Self-Esteem Scale (RSE) at baseline, post intervention, 6 and 12 months follow up
12. Self-regulation skills will be measures using the Short Self-Regulation Questionnaire (SSRQ) at baseline, post intervention, 6 and 12 months follow up

The following additional outcomes will be measured at start of trial, half-way through and at end of the trial:
1. Participating therapists' confidence in treating eating disorders (self-report on relevant therapeutic skills and emotions while treating patients with Eating Disorders)
2. Therapists' perceived benefits of everyBody Plus for patients (STEP, modified for online interventions)

For health-economic analyses, the Client Service Receipt Inventory (CSRI) will be administered at baseline, post intervention and at the 6 and 12 month follow ups.
