From Markers to Interventions: The Case of Just-in-Time Stress Intervention

The use of sensor-based assessment of stress to trigger the delivery of just-in-time intervention has the potential to help people manage daily stress as it occurs in the person’s natural environment. The challenge is to mine the continuous stream of sensor data and identify those few opportune moments for triggering an intervention—when there is sufficient confidence in the accuracy of the sensor-based stress markers, in order to limit interruptions to the daily lives. In this chapter, we describe the process of developing a real-time method to identify stress episodes, from a time series of stress markers, to inform the triggering of just-in-time stress-management interventions.
