Abstract

Background: We describe the theoretical rationale and protocol for Self-Help And Recovery guide for Eating Disorders (SHARED), a trial investigating whether a guided self-care intervention (Recovery MANTRA) is a useful addition to treatment as usual for individuals with anorexia nervosa. Recovery MANTRA, a 6-week self-care intervention supplemented by peer mentorship, is a module extension of the Maudsley Model of Treatment for Adults with Anorexia Nervosa and targets the maintenance factors identified by the cognitive-interpersonal model of the illness.

Methods: Patients accessing outpatient services for anorexia nervosa are randomized to either treatment as usual or treatment as usual plus Recovery MANTRA. Outcome variables include change in body weight at the end of the intervention (primary) and changes in body weight and eating disorder symptoms at immediate and extended follow-up (6-months; secondary). Change is also assessed for the domains identified by the theoretical model, including motivation, hope, confidence to change, positive mood, cognitive flexibility, therapeutic alliance and social adjustment. Feedback from peer mentors is gathered to understand the impact on their own well-being of providing guidance.

Discussion: Results from this exploratory investigation will determine whether a larger clinical trial is justifiable and feasible for this affordable intervention, which has potential for high reach and scalability.

Trial registration: ClinicalTrials.gov NCT02336841 .
