Evaluating and Implementing a Smartphone Application Treatment Program for Bulimia Nervosa and Binge Eating Disorder

Summary

Bulimia nervosa and binge eating disorder pose a public health concern due to their high co-occurrence with other psychiatric disorders and poor physical health outcomes. It is therefore concerning that less than half of these patients seek treatment for their condition. People may be reluctant to seek treatment due to not wanting to disclose symptoms to family members. Even for those who do wish to seek help, treatment is often inaccessible due to the geographic centralization of eating disorder specialists and a low ratio of specialists to patients. Therefore, the aim of this study is to test a potential solution to these problems and make eating disorder care more private and accessible.

One possible way to improve the accessibility of treatment is through smartphone applications (or "apps"). We are testing an app called Recovery Record, which is primarily a tool used to self-monitor eating habits, where patients record their meals and related thoughts, feelings, emotions, and behaviours (e.g., binge eating/purging). The app also offers additional features such as discrete reminders to log meals, positive reinforcement, social support, coping strategy suggestions, and linking users with clinicians for real-time feedback and suggestions. The application is scientifically supported and has been tested with positive results.

Recently, app developers have created a computer-automated 8-week treatment program that uses the patient's data to provide a tailored and individualized treatment program. This program aims to mimic the process of therapy by checking in with users, reminding them of their reasons for wanting to recover, and working towards goals. We will be testing this automated app treatment program, comparing it both with and without input from a trained coach providing individualized feedback to users.

Interventions

BEHAVIORAL

Adaptive Recovery Record App

Participants will use the Recovery Record smartphone app, which is a meal monitoring tool, that incorporates discrete reminders, motivational tools, social support, summative feedback, and coping skill suggestions. Participants will also receive tailored, algorithm-generated content in a structured manner that mimics the progression of psychotherapy (e.g., checking in with users, reminding them of their reasons for wanting to recover, and working towards goals) over the course of 8 weeks.

BEHAVIORAL

Standardized Coaching

Coaches (dietitians or mental health clinicians) will review patients' logs daily and participants will receive one communication of standardized feedback each day through the app based on their food records. A standardized feedback manual to be used by coaches has been developed by co-investigators (two PhD psychologists and one psychiatrist), and all feedback will be monitored for consistency and quality by co-investigators.
