Suicide attempt and suicide

Suicide is a public health problem. During the 1980's and 1990's the suicide rate decreased substantially in Sweden, but this development has not continued into the first decade of 2000's. Suicide attempts, on the contrary, have increased dramatically among young females but also in young males.

We are investigating the situation and prognosis after suicide attempt, to improve suicide risk assessment and management.

We have shown that the coexisting psychiatric diagnosis at the suicide attempt affects the rate of later suicide. In subjects with severe mental disorder, such as schizophrenia and affective disorders, the risk is higher than in subjects with less pronounced symptom severity. We have also shown that the method used at the suicide attempt is relevant to the risk of suicide in the shorter and longer run. A violent method implies a higher risk, particularly when severe mental disorder is evident, but also in persons without obvious mental disorder.

We are studying large patient samples with a particular focus on young people and suicidal behaviour. A series of studies concerns the effect of a family history of suicide. Several studies concern violence and suicide in relationship to mental disorder. One study focuses suicide in relationship to university studies. The common aim is to find ways to understand and prevent suicide.
