Just-In-Time Adaptive Interventions (JITAI) and the Need for Computational Dynamic Modeling

Riley, William

The advent of mobile technologies has allowed behavior change interventions to tailor interventions not only at baseline but also to adapt and adjust interventions throughout the change process. These frequently adapting interventions, termed "Just-in-Time Adaptive Interventions" or JITAI have intuitive appeal, but developers of JITAI lack an adequate conceptual or empirical basis for making these adaptations. Computational dynamic modeling approaches provide a robust approach to identifying points of adaptation and testing these adaptations. This paper describes JITAI and how computational models can be applied to this form of behavioral intervention.
