ESM Power & Design Planner
A free, browser-based sample-size and design planner for triggered ESM/EMA studies.
Most power tools assume a fixed number of observations per person. In event- and location-triggered ESM, that number is random — so the usual formulas do not apply. This planner simulates power, precision, and convergence for triggered and fixed designs across the full multilevel model class, answering instantly from a precomputed grid or running the model live in your browser. Open a study in SMAAT and it prefills your design.
Runs in your browser · no install·Anyone planning or reviewing an ESM/EMA study·Free · open source
A fillable working document for designing an ESM/EMA study.
Goes from research question through item set, schedule, power analysis, compliance monitoring, and pre-registration in one structured template. Includes a notification-schedule worksheet and a compliance-monitoring checklist. IRB-ready.
