Adherence
Adding complex goal-setting (Achieve) and nutrition (Nourish) modules to a basic weight loss program significantly reduces user engagement and retention compared to the basic program alone.
Keep digital weight loss programs simple. Adding too many modules or complex goal-setting features can overwhelm users and reduce engagement. A basic, focused program often yields better adherence than a complex, multi-module one.
GoodRefutesHIGH confidence
All of the significant treatment effects and interactions with treatment indicated that the basic Balance intervention produced substantially higher initial engagement rates than the others... substantially fewer participants met criteria for engagement in the other interventions.
Why this rating
RCT with clear engagement metrics, though engagement was defined dichotomously.
