Assessing Moderated Effects of Mobile Health Interventions on Behavior

Abstract

A critical question in the development of mobile health interventions is, when and in which contexts, is it most useful to push intervention content to the user. This question concerns time-varying dynamic moderation by the context on the effectiveness of intervention pushes. In this talk we discuss the micro-randomized trial design and associated data analyses for use in assessing moderation. We illustrate this approach with mobile health intervention data.
