Adverse life events are an established risk factor in completed suicide.
However, few studies have examined life events and suicide in schizophrenia.
We investigated and compared schizophrenia suicide victims and age-and sex-matched victims without schizophrenia as part of a psychological autopsy study of all suicides in Finland over a 12-month period.
Recent life events were examined retrospectively by interviewing next of kin using a structured life event questionnaire.
Overall, nearly half (46%) the schizophrenia subjects had had adverse life events before suicide, significantly less than the nonschizophrenia subjects (83%). In both groups, however, suicide was preceded by life events independent of the victims'own behavior, such as death of a close person or illness in the family.
Life events overall were more common among schizophrenia outpatients (52%) than inpatients (22%), and the association of life events with suicide was clearest among a subgroup of outpatients in residual phase who had used neuroleptic medication regularly.
Overall, the prevalence of recent adverse life events varied between clinical subgroups of victims with schizophrenia, which may have implications for suicide prevention.
