Can Digital Technology Prevent Suicides?
Psychiatric disorders are strong predictors of a higher mortality risk and account for a significant number of years lost to premature mortality across most populations. The increased risk of mortality is due to the increased likelihood of suicide for which the Global Burden of Disease reports to be the 13th leading cause of death.
Although the presence of a psychiatric disorder is a major risk factor for suicidal behaviour, it isn’t the only risk factor. Studies have shown that suicidal behaviour can come about through an individual’s genetic disposition, the impact of stressful life events, or psychological factors such as feeling hopelessness or having high emotional reactivity.
For most psychiatric disorders there are evidence-based treatments available that can prevent or reduce the risk of suicide. However, suicide rates have remained unchanged and this is in part by the lack of understanding of how the complex interplay between mental illness, its comorbidities and other psychosocial and biological factors influence suicidal behaviour and suicide.
