Personalized behavior change support for disease prevention

Healthy lifestyle is essential in prevention of chronic diseases. However, people need motivation and support to achieve and to maintain behavior changes. Moreover, effective behavior change support should be personalized to individual's unique characteristics, needs and context. This paper presents a blueprint of an ICT system, which is able to provide holistic, dynamic support for healthy behaviors, engaging also various co-producers in the health journey of a person. Three main concepts in the system are Virtual Individual, which maintains the user's personal profile, PGS-Mall, which collects various health and well-being services into one place, and HealthGuides, which support healthy choices in everyday life and coordinate the interactions between the user, the system, and other co-producers of health.
