Ecological Momentary Assessment

Ecological Momentary Assessment (EMA) is a powerful tool that captures participants’ experiences in the present moment, within their living environment. With EMA, notifications can be displayed, questionnaires can be sent, GPS data can be captured, and native mobile device sensors can be used without the need to install an application. Capture participants’ lived experience with EMA*.
