While many approaches to reducing relapse after hospital care have been tried, there is little information about which treatment elements confer benefit. This trial, Relapse Prevention and Changing Habits (REACH+), targets the habitual control of maladaptive behavior to support patients with AN in the 6 months after acute treatment, a time of high vulnerability to relapse. Each component of REACH+ addresses a question that is critical to answer in order to identify and optimize a relapse prevention treatment package that balances efficacy and burden. We will test the acceptability and feasibility of 5 components that together target habits: 1) Behavioral, 2) Cognitive, 3)Motivation, 4) Food Monitoring, and 5) Skill Consolidation. In the Preparation Phase, 10 participants were enrolled, and accessibility and feasibility of the treatment package was examined. The current Optimization Phase includes a finalized treatment manual (including an online platform) and will test each component's contribution to weight maintenance after acute treatment.
This study aims to optimize a treatment package for the relapse prevention treatment of AN. In the Preparation Phase, we examined accessibility and feasibility of the treatment package.~In the current Optimization Phase, we will identify which components of treatment contribute to positive outcomes after acute hospitalization. We will carefully evaluate maintenance of remission, measured by rate of weight loss and end-of-trial status.
