Psychiatric Aspects of Suicidal Behaviour: Schizophrenia (IN: The International Handbook of Suicide and Attempted Suicide, edited by K Hawton & K van Heeringen)

The literature on suicide in schizophrenia is reviewed, together with data from recent studies. The risk of suicide is 40 times higher in the schizophrenic population compared to the general population. Major risk factors include: male gender, chronic illness with frequent relapse, frequent & short hospitalization, family history of suicide, past suicidal & impulsive behaviour, negative attitudes toward treatment, higher IQ, psychosis & depression. Treatment aimed at prevention must target the identified risk factors. The effective prevention of suicide requires a comprehensive & systematic approach. (86 refs.)
