This study aims to utilize emerging mobile application technology, as a tool for increasing the potency, accessibility, and efficacy of a guided self-help version of cognitive-behavioral therapy (CBT-GSH) for binge eating. The feasibility and efficacy of the adapted smartphone application created by Noom Inc., Noom Monitor, will be examined through a randomized control trial comparing CBT-GSH + APP with CBT-GSH conducted at the Mount Sinai School of Medicine's Eating and Weight Disorders Program. The investigators hypothesize that CBT-GSH with the addition of the Noom Monitor, will be significantly more acceptable, have greater uptake of self-monitoring, greater adherence to treatment, and greater reduction in objective binge episodes (OBEs) than standard CBT-GSH.

Bulimia nervosa (BN) and Binge Eating Disorder (BED) are both characterized by the primary symptoms of binge eating and by significant levels of impairment and psychiatric co-morbidity, affecting approximately 3-5% of the US population. Guided self-help cognitive behavioral (CBT-GSH) therapy has been shown to be an efficacious treatment to reduce binge eating, performing comparatively to full-scale psychotherapy interventions and is a cost-effective empirically supported treatment that has been demonstrated to reduce total health care costs when delivered by trained professionals in primary care settings. Despite the evidence that CBT-GSH offers an effective and financially advantageous treatment for BN and BED, there is evidence of limited uptake for CBT-GSH among both clients and therapists as evidenced by high dropout rates and perceived impediments to therapeutic change. The primary intervention in the CBT-GSH is self-monitoring, which is uniquely effective at reducing binge eating episodes and is packaged with other behavioral strategies including regular eating, using alternatives to binges or purging, problem solving, eliminating rigid dietary practices, and regular weighing. Self-monitoring in CBT-GSH is both time-intensive and cumbersome in its traditional paper format and behavioral strategies require a high degree of engagement outside of session. These burdens lead to reduced therapeutic adherence, which is essential to the efficacy of CBT-GSH. Initial evidence with text messaging interventions suggest increased treatment and self-monitoring adherence for BN. A yet unexplored advantage of mobile application technology is the ability to synthesize real-time data to provide feedback on patient progress. Providing therapists with direct feedback about patient progress has a well-documented effect on treatment outcome and adherence. Thus, mobile application technology offers an innovative opportunity to increase client and therapist uptake of CBT-GSH by (1) reducing the burden of self-monitoring and de-stigmatizing the act of real-time meal recording, (2) offering between-session application of CBT-GSH principles , (3) facilitating feedback to therapists about patient progress. This study proposes to develop a commercial product, the Noom Monitor, to capitalize on emerging mobile application technology thus enhancing the acceptability and efficacy of CBT-GSH. This will be accomplished by adapting Noom Inc.'s current commercial mobile product, Noom, into a therapy transfer application for individuals with BN. The acceptability, treatment adherence, and preliminary efficacy of the adapted application will be examined through a randomized control trial comparing CBT-GSH + Noom Monitor with traditional CBT-GSH conducted at the Mount Sinai School of Medicine's Eating and Weight Disorders Program. The innovative utilization of technology to assist in mental health interventions has widespread implications outside of this proposal, which will be used to strategize the further development and commercialization of this product.
