Ecological Momentary Assessment

Definition

Ecological Momentary Assessment (EMA) is a research and clinical method that uses smartphones or other devices to collect real-time information about your thoughts, feelings, and behaviours as you go about your daily life. Instead of trying to remember how you felt weeks ago during a therapy session, EMA captures your experiences in the moment, providing more accurate and detailed information about your mental health patterns. This approach helps you and your healthcare provider understand your symptoms better and make more informed treatment decisions.
