The Right Support at the Right Time: Just-in-Time Adaptive Interventions (JITAIs) for Substance Use with Dr. Kristina Phillips

December 4, 2025 10 am – 11 am PT

Just-in-time adaptive interventions (JITAIs) represent a cutting-edge approach to promoting healthier behaviors, including the reduction of substance use. By delivering personalized, real-time support precisely when individuals need it most, JITAIs have the potential to transform the landscape of mobile health (mHealth). In this seminar, Dr. Kristina Phillips will introduce the conceptual and methodological foundations of JITAIs, including a focus on intensive longitudinal data collection. Key challenges related to privacy and sustained engagement will be addressed, alongside a review of experimental designs commonly employed to optimize JITAIs. The talk will conclude with an example from an ongoing clinical trial evaluating the preliminary efficacy of a novel JITAI targeting young adults who co-use cannabis and alcohol, illustrating the practical application of these methods.
