We are expert in the development of intelligent systems and devices. These systems not only facilitate efficient intervention delivery, but also offer unique intervention opportunities. They can provide useful information, help users remember and prioritise plans, allow them to self-monitor feelings and behaviours and receive moment-to-moment feedback. They can facilitate goal setting and goal review and help communicate intentions, achievements and needs to others. They can empower people to assess themselves and initiate and sustain self-care actions. At the same time, these systems can identify when people need professional help and can facilitate communication with relevant health care professionals. Evidence supports their capacity to facilitate improved self-management of health-related behaviour and care of long-term illnesses. The MCBC has developed and demonstrated the effectiveness of digital interventions for smoking cessation and physical activity. MCBC is developing and evaluating intelligent digital systems to support behaviour change in cancer survivors and also working to integrate personal digital devices with health systems data.
