Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The current study will use a 2 x 2 full factorial design in which 76 individuals with bulimia nervosa (BN) or binge eating disorders (BED) are assigned to one of four treatment conditions, i.e., representing each permutation of Advanced DDS with Coaches (Advanced DDS with Coaches ON vs. Advanced DDS with Coaches OFF) and JITAIs (JITAIs ON vs. JITAIs OFF) as an augmentation to self-help CBT program. Self-help CBT will deliver an evidence-based program based on Dr. Chris Fairburn's Overcoming Binge Eating self-help book via a smartphone app without clinician involvement. This app will constitute 12 treatment modules and an electronic self-monitoring form to record eating and eating disorder behaviors for use over 12 weeks without clinician involvement. The primary aims of the study will be to (1) Test target engagement, i.e., that each factor including Advanced DDS with Coach and JITAIs produces greater improvements in treatment adherence and skills utilization, (2) Test the feasibility and acceptability of two intervention factors as adjuncts to self-guided CBT program for binge eating; (3) Test the initial efficacy, i.e., that each factor including Advanced DDS with Coach and JITAIs will produce greater improvements in binge eating frequency at post-treatment, and 3 months follow-up; and (4) Test target validation, i.e., that improvements in treatment adherence and skills utilization will be associated with reductions in binge eating. The exploratory aim will be to quantify the intervention factors' interaction effects, which may be partially additive (because intervention factors overlap and/or there is diminishing return), fully additive, or synergistic (in that intervention factors may partially depend on each other).

Base self-help CBT program plus Advanced Digital Data Sharing (ADDS) with Coaches
When Advanced DDS with Coaches is turned ON, coaches having a bachelor's degree in health-related fields will have access to a secure web portal called the clinical portal. The portal will also mimic four key behavior change techniques typically employed by an expert clinician including 1) gather data on target behaviors from the base self-help app (i.e., uptake of weekly module, self-monitoring compliance, and skills use), 2) synthesize participants' behavioral data on treatment targets, 3) flag data to indicate behaviors needing improvement and 4) use sophisticated algorithms to generate recommendations for intervening on identified data patterns. Using this information, the coaches will send one weekly email to facilitate improvement in treatment targets over 12 weeks. When Advanced DDS with Coaches is turned OFF, participants' will not have their data shared and will not receive emails from the coaches.
Base self-help CBT program
The self-help app will deliver 12 modules that will be based on Chris Fairburn's "Overcoming Binge Eating" self-help book, the most widely used self-help resource for binge eating over 12 weeks. Treatment modules will aim to 1) provide psychoeducation on maintenance factors for binge eating, 2) teach CBT skills designed to interrupt these maintenance factors, and 3) coach participant to set personalized goals each week. Modules will be completed in succession over the course of 12-weeks and a new module will be made open each week. In addition, participants will track their eating and eating disorder behaviors using the self-help app.

Base self-help CBT program plus Just-in-time, adaptive interventions (JITAIs)
When JITAIs are turned ON, the base self-help app will be used to deliver targeted, personalized and automated interventions during algorithm-identified moments when participants could benefit from receiving an intervention for improving two key areas including 1) treatment adherence, and 2) skills utilization based on responses (or lack thereof) in self-help app. When JITAIs are turned OFF, participants will not receive interventions in real-time on the base self-help app.
