Description:

Just-in-time adaptive interventions (JITAI) are an intervention design aiming to provide the right type/amount of support, at the right time, by adapting to an individual's changing internal and contextual state. The availability of increasingly powerful mobile and sensing technologies underpins the use of JITAIs to support healthy behaviors such as adherence to medications, increasing physical activity, managing stress and so on.  JITAI decision rules input an individual's current internal and contextual state, such as their location, recent adherence and current stress and output behavioral support, such as a tip for how to be active in their current location or recommendations to practice a stress management strategy. Personalizing JITAIs (pJITAIs) deploy an AI algorithm to update and improve the JITAI decision rules as individuals experience the intervention.    In this talk we discuss how we are using AI algorithms to personalize JITAIs.
