Micro-randomized Trials and Moderated Effects of Mobile Health Intervention Pushes on Behavior

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 concerns time-varying dynamic moderation by the context on the effectiveness of intervention pushes. In this talk, Susan Murphy, will discuss the micro-randomized trial design and associated data analyses for use in assessing moderation. This approach will be illustrated with data from a micro-randomized trial of a physical activity intervention, Heartsteps.

Susan A. Murphy is the H.E. Robbins Distinguished University Professor of Statistics & Professor of Psychiatry and a Research Professor at the Institute for Social Research, all at the University of Michigan. Her lab focuses on improving sequential, individualized, decision making in health, in particular on clinical trial design and data analysis to inform the development of just-in-time adaptive interventions in mobile health. The lab's work is funded by National Institute on Drug Abuse , by National Institute on Alcohol Abuse and Alcoholism, by National Heart, Lung and Blood Institute and by National Institute of Biomedical Imaging and Bioengineering.

Susan is a Fellow of the Institute of Mathematical Statistics, a Fellow of the College on Problems in Drug Dependence, a former editor of the Annals of Statistics, a member of the US National Academy of Sciences, a member of the US National Academy of Medicine and a 2013 MacArthur Fellow.
