Videos: Introduction to Just-in-Time Adaptive Interventions

March 13, 2017

Susan MurphyIn our latest video releases, Methodology Center Investigator Susan Murphy introduces some innovative tools for building adaptive health interventions that can be delivered through a smartphone or other mobile device. In the first video, she introduces the just-in-time adaptive intervention (JITAI), a type of intervention that uses real-time data to deliver interventions as needed via mobile devices. In the second video, she introduces the microrandomized trial, an innovative trial design for building JITAIs. In the third video, Susan discusses data analysis to inform the development of a JITAI.
