What Is EMA in Spica

EMA is a scientifically validated method for capturing patient-reported symptoms, behaviors, and contextual information in real time. By collecting data in the moment and in natural environments, EMA provides accurate, reliable, and ecologically valid insights that go beyond traditional memory-based recall.
