Studies suggest virtual check-ins boost participant adherence—how have these tools affected your studies?
In our 6‑month device study, ‘virtual check-ins’ only boosted adherence after we let participants pick SMS or app at consent and set a 10‑minute evening window for RPM prompts. If you try one change, make channel and time preference part of onboarding; it cut mid‑study dropouts about 18% for us, though anything over three nudges a week felt intrusive.
