SMART Designs for Advancing mHealth Adaptive Interventions S.A. Murphy mHealth Evidence Workshop August, 2011

Adaptive Interventions are individually tailored sequences of treatment decisions. Adaptive interventions tailor these decisions according to dynamically evolving individual information. What is an Adaptive Intervention? Intervention Design

3 –Example Dynamic Individual Information: Craving, mood, slips/relapse, activity level, pain level, proximity to undesirable location, symptoms –Example Decisions: Encouraging messages, dosage level, reminders, goal suggestions, to buddy, alarm to health care provider Intervention Design

4 –Goal: Inform Construction of Adaptive Intervention Experimental, Data-Based –Pinpoint Critical Decisions that Require Explication Randomize among alternative decision options at these decisions SMART Design Experimental Design

5 –Example Critical Decisions: If individual is in dangerous location, is it effective to send a message? Which of several types of messages is most effective? –Randomization Randomize between sending a message or not sending a message Randomize between types of messages Experimental Design

6 Opens black box! Disentangle effect of message from why message was provided. Why Randomize at each critical decision? Experimental Design
