Abstract

Mobile health applications have the potential for addressing chronic health conditions, but challenges exist in adherence, or the extent to which a patient conducts the activities defined in a clinical protocol. High levels of adherence should lead to greater effects of the intervention; the greater fidelity to the protocol, the more benefit one should receive from the protocol. Further, this delivery mechanism supports just-in-time 'micro' interventions, or smaller yet more frequent dosages of skill practice. mHealth has limitations in these areas; the ability of patients to sustainably adhere to a protocol, and to drive intervention effect sizes. This research considers personalized just-in-time adaptive micro-interventions as a potential remedy to these limitations. Specifically, in the context of a pediatric anxiety protocol, we introduce an approach to drive greater levels of adherence and effect sizes by incorporating per-patient information. This approach has been implemented within an mHealth app for middle school that was successfully pilot-tested in the Phoenix area. The number of users is small (n=3) so a case-by-case analysis of app usage is presented. Simulated user behaviors based on models of adherence and effect sizes over time are presented as a means to demonstrate the potential impact of personalized deployments on a larger scale.
