About Shawna N. Smith
Shawna N. Smith, PhD, is a sociologist and methodologist interested in improving population health through optimizing and expanding delivery of behavioral healthcare services and interventions. Much of her work focuses on improving access to behavioral health evidence-based practices in community-based settings and physical healthcare spaces. As Research Assistant Professor at the University of Michigan Medical School (Departments of Psychiatry & Internal Medicine), she currently works on four NIH funded projects aimed at improving population health by increasing access to physical activity, collaborative care and cognitive behavioral therapy interventions through new delivery modalities and implementation strategies. Methodologically, her work employs microrandomized trials (MRT) and cluster-randomized sequential multiple-assignment randomized trial (SMART) designs to evaluate contextual moderation, comparative effectiveness, and optimal treatment delivery and intervention support.
About the Guest Lecture
Mobile technologies are increasingly being used to deliver health and behavior change-related (mHealth) interventions. By combining opportunities for real-time, in situ intervention delivery with (frequently passive) streams of intensive data collection, researchers are now able to develop and optimize just-in-time adaptive interventions (JITAIs). JITAIs are mHealth interventions that use decision rules to deliver the right intervention components at the right times and locations to optimally support individuals’ health behaviors over the long-term.
This talk will describe the key elements of a JITAI, and also present one experimental design method for optimizing JITAIs, the microrandomized trial (MRT). In MRTs, participants are sequentially randomized to receive intervention components at multiple decision points throughout study conduct, with the result that each participant may be randomized hundreds or thousands of times over the course of a study. As such, MRTs enable modeling of causal treatment effects and time-varying effect moderation for individual intervention components on proximal outcomes of interest within a JITAI. Examples and results from the six-week HeartSteps study, an MRT designed to inform a JITAI for increasing physical activity, will be used to illustrate MRT design, analyses and potential further work relevant to JITAI optimization.

Today, we start the new BLV project Mobile Diet Coach. The project aims to provide fully-automated interventions to improve food literacy and support health-promoting dietary behaviors.

Results of menuCH, the National Nutrition Survey conducted 2014 in Switzerland, showed that adults’ food intake is not fully in line with Swiss food-based dietary guidelines that is, the Swiss food pyramid. Therefore, with this project the Federal Food Safety and Veterinary Office (FSVO) seeks for new and effective means to support people in eating a better balanced diet.

Advanced technology-based delivery modes, such as a fully automated digital coach, make interventions to improve food literacy and support health-promoting dietary behaviors accessible for the entire population. Consumers may consult the Mobile Diet Coach on their own initiative or because health professionals, such as physicians, nutritionists, and registered dieticians invited them to do so. Elements like self-monitoring of food consumption and comparisons of intake to dietary guidelines, tailored practical feedbacks, goal setting and action plan, gamification etc. will encourage users to strive for a health-promoting diet. With help of the Mobile Diet Coach, consumers will gain nutritional knowledge and improve skills and abilities that are essential to take health-promoting food decisions in many situations and settings of daily life.

The Android and iOS applications will build on the behavioral health intervention platform MobileCoach.
