Item type:Publication, The Future of Medicine: Preventative mHealth Interventions and Health DigitizationRising healthcare costs are pushing healthcare systems to their limits. Non-communicable diseases (NCDs) such as diabetes or cancer cause more than half of healthcare spending. Research shows that NCDs depend on a set of modifiable risk factors and that unhealthy human lifestyles are responsible for 45%75% of disease risk. Preventative health interventions supporting healthier lifestyles are thus needed to combat the rise in NCDs, to control health care spending, and to future-proof healthcare systems. However, currently only 3% of health spending are allocated to prevention. Moreover, the potential of mobile health (mHealth) technologies for health behavior change remains underresearched. This dissertation consists of four articles that explore the potential of preventative mHealth interventions in supporting healthier lifestyles. It also investigates how digital technologies can help future-proof healthcare systems. Article I provides a comprehensive summary of the existing research on the short- and long-term effectiveness of mHealth physical activity interventions. It quantitatively summarizes 117 studies in a meta-analysis and finds that mHealth physical activity interventions lead to small to moderate activity increases that are maintained up to 14 months post intervention. Building on the first article, Article II investigates how gamification can increase the long-term effectiveness of preventative mHealth interventions. Based on two case studies, it develops a novel motivational framework for gamification and provides guidelines for gamifying activity tracking apps to prevent motivational crowding out. Article III explores the use of future-self avatars to overcome present bias in preventative mHealth interventions. Using a randomized-controlled trial research design, the article finds that the future-self avatar intervention directionally increases physical activity and improves the nutritional quality of food purchases. Article IV takes a broader perspective and explores the impact of digital technologies on future-proofing healthcare systems.Type:doctoral thesis
