The just-in-time adaptive intervention (JITAI) is an intervention design for supporting health behavior changes of an individual especially via mobile technologies. In this position paper we discuss JITAIs as a multi-level modeling problem focusing on the structure of multi-level JITAI models. JITAIs are designed on a generic level, configured for studies, personalized for participants, and evaluated at particular points in time. In this paper we model the multi-level structure of JITAI studies using composition and association classes. We sketch how to transform such models to multi-level models aligned with the multi-level theory. Finally, we discuss challenges and requirements for JITAI systems related to multi-level modeling.
