iBeChange is European project funded under the framework of the Horizon 2023. Recognizing the significant global burden of cancer caused by potentially modifiable behavioral, environmental, and psychosocial factors, there is a pressing need for widespread programs promoting Behavior Change (BC) and Emotional Management (EM). In response to this need, the iBeChange project aims to design, develop, and test the iBeChange platform. This innovative system is focused on facilitating sustainable behavioral change and emotion management, with a specific emphasis on behaviors scientifically proven to reduce cancer incidence and mortality. iBeChange proposes a new approach that will combine machine learning models with health psychology theories and clinical guidelines to identify effective interventions that can help individuals to reduce the risk of developing cancer.
