Abstract
BACKGROUND Adaptive behavioral interventions are individualized interventions that vary support based on a person s evolving needs Digital technologies enable these adaptive interventions to function at scale Adaptive interventions show great promise for producing better results compared with static interventions related to health outcomes Our central thesis is that adaptive interventions are more likely to succeed at helping individuals meet and maintain behavioral targets if its elements can be iteratively improved via data driven testing ie optimization Control systems engineering is a discipline focused on decision making in systems that change over time and has a wealth of methods that could be useful for optimizing adaptive interventions OBJECTIVE The purpose of this paper was to provide an introductory tutorial on when and what to do when using control systems engineering for designing and optimizing adaptive mobile health mHealth behavioral interventions OVERVIEW We start with a review of the need for optimization building on the multiphase optimization strategy MOST We then provide an overview of control systems engineering followed by attributes of problems that are well matched to control engineering Key steps in the development and optimization of an adaptive intervention from a control engineering perspective are then summarized with a focus on why what and when to do subtasks in each step IMPLICATIONS Control engineering offers exciting opportunities for optimizing individualization and adaptation elements of adaptive interventions Arguably the time is now for control systems engineers and behavioral and health scientists to partner to advance interventions that can be individualized adaptive and scalable This tutorial should aid in creating the bridge between these communities
