Also written as: EMA — Ecological Momentary Assessment
Real-time data collection method capturing participants' experiences and behaviors in their natural environment.
Full Definition
Ecological momentary assessment (EMA) is a research methodology that involves repeated sampling of participants' current behaviors, experiences, and mood states in real-world settings using electronic devices such as smartphones or tablets. EMA minimizes recall bias by capturing data close to the time of experience and provides insights into symptom variability and environmental triggers. This approach is particularly valuable in psychiatric research for understanding mood fluctuations, medication adherence, and daily functioning patterns outside clinical settings.
Usage
Usage note: Often abbreviated as EMA after first mention; emphasizes real-time, naturalistic data collection.
