JITAIs are a special type of adaptive intervention where—thanks to mobile technology like activity sensors and smartphones—an intervention can be delivered when and where it is needed. MRTs are a new trial design for addressing scientific questions concerning the construction of highly effective JITAIs. In this workshop, we will introduce JITAIs and provide examples of key scientific questions that can be answered using MRTs. Useful primary aim data analysis methods for MRTs will also be discussed.
Day 1 and part of Day 2 of this workshop will focus on JITAI and MRT design considerations and applications. Much of Day 2 will be allotted to understanding primary aims in an MRT and conducting associated primary aim analyses.
