Interventions

  • MI-Coach: ED Mobile App — COMBINATION_PRODUCT
    The MI-Coach: ED mobile app is a self-guided intervention designed to enhance motivation and readiness for treatment in adults with eating disorders. The app includes seven sequential modules based on motivational interviewing (MI) principles, addressing ambivalence, self-acceptance, compassionate motivation, behavior change goals, sustain and change talk, commitment language, and relapse prevention. Each module incorporates interactive content, including educational videos, articles, and exercises, tailored to support motivation across a range of eating disorder diagnoses. The app is designed to be user-friendly and scalable, providing an accessible, cost-effective solution for individuals on waitlists for formal eating disorder treatment.

Study Details

The goal of this randomized controlled trial is to evaluate whether a mobile app-based motivational interviewing intervention (MI-Coach: ED) can improve motivation and readiness for treatment in adults with eating disorders who are currently on waitlists for provincially funded eating disorder services in British Columbia. The main questions it aims to answer are: * Does the use of MI-Coach: ED improve overall motivation, confidence, and readiness for treatment compared to treatment-as-usual (waitlist with no intervention)? * Does the app help mitigate declines in motivation over time among waitlisted individuals? Researchers will compare participants using the MI-Coach: ED app to a delayed treatment control group to assess differences in motivation, readiness for treatment, and associated clinical outcomes. Participants will: * Treatment group: Use the MI-Coach: ED app for four weeks, completing interactive modules focused on motivation and readiness for change, while also completing weekly brief assessments of motivation. * Delayed treatment group: Remain on the waitlist with no intervention for four weeks while completing weekly brief assessments of motivation. After this period, they will receive access to the MI-Coach: ED app and be integrated into the treatment group. * Complete pre-test and post-test questionnaires at 0, 4, 8, and 12 weeks assessing motivation, eating pathology, anxiety, and depressive symptoms. This study aims to inform evidence-based practices for reducing the adverse effects of long waitlist durations on individuals with eating disorders.

Arms

  • Experimental: Immediate Treatment Group (MI-Coach: ED Users)
    Participants randomized to the immediate treatment group will begin using the MI-Coach: ED app immediately for a four-week intervention period. During this time, participants will complete interactive modules designed to enhance motivation and readiness for treatment, focusing on topics such as ambivalence, self-acceptance, compassionate motivation, and behavior change strategies. Weekly brief assessments of motivation and readiness for change will be completed throughout the initial four-week period.
  • No Intervention: Delayed Treatment Group (Waitlist Control)
    Participants randomized to the delayed treatment group will remain on the waitlist without access to the MI-Coach: ED app for the first four weeks. During this period, participants will complete weekly brief assessments of motivation and readiness for change to evaluate changes while waiting for access to the intervention. No additional interventions or activities will be provided during this initial four-week period.
  • Experimental: Combined Treatment Group
    This arm includes all participants who engage with the MI-Coach: ED app during the eight weeks following the initial four-week period. Participants from the immediate treatment group (Arm 1) will continue to use the app for the full 12 weeks of the study, including an eight-week extended intervention period and follow-up assessments at 8 and 12 weeks to evaluate the app's sustained effects. Participants transitioning from the delayed treatment group (Arm 2) will also use the app for an eight-week intervention period after their initial four-week waitlist phase, ensuring both groups have the same opportunity to complete the full intervention. Weekly assessments of motivation and readiness for change will continue for all participants during their respective intervention periods, along with follow-up assessments to compare immediate and delayed access effects, as well as the app's long-term impact on motivation and clinical outcomes.
