H. Heila et al., Life events and completed suicide in schizophrenia: A comparison of suicide victims with and without schizophrenia, SCHIZO BULL, 25(3), 1999, pp. 519-531
Adverse life events are an established risk factor in completed suicide. Ho
wever, 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 s
tudy of all suicides in Finland over a 12-month period. Recent life events
were examined retrospectively by interviewing next of kin using a structure
d life event questionnaire. Overall, nearly half (46%) the schizophrenia su
bjects had had adverse life events before suicide, significantly less than
the nonschizophrenia subjects (83%). In both groups, however, suicide was p
receded by life events independent of the victims' own behavior, such as de
ath of a close person or illness in the family, Life events overall were mo
re common among schizophrenia outpatients (52%) than inpatients (22%), and
the association of life events with suicide was dearest among a subgroup of
outpatients in residual phase who had used neuroleptic medication regularl
y. Overall, the prevalence of recent adverse life events varied between cli
nical subgroups of victims with schizophrenia, which may have implications
for suicide prevention.
