Over the last ten years, the rate of suicide in children and young people has been increasing. Research suggests for every death through suicide almost 135 lives can be affected.  Professor John’s research looks at anonymised data linking across sectors from school attendance and absences, examination attainment and medical appointments with the GP or in hospitals to social media, Google analytics and media reporting. Whilst this data is never linked to a named individual the patterns of behaviours of a number of individuals can build a picture of how interventions can be designed, protocols put in place and policies developed to help inform and train professionals in contact with those who self-harm or are at risk of suicide.
