E. Isometsa et al., RECENT LIFE EVENTS AND COMPLETED SUICIDE IN BIPOLAR AFFECTIVE-DISORDER - A COMPARISON WITH MAJOR DEPRESSIVE SUICIDES, Journal of affective disorders, 33(2), 1995, pp. 99-106
While recent psychosocial stress has been shown to be associated with
the initiation of both first and subsequent illness episodes in bipola
r affective disorder, its relationship to completed suicide in bipolar
disorder is not known. As a part of a nationwide psychological autops
y study, two populations representing all suicides in Finland in DSM-I
II-R bipolar disorder or unipolar major depression were comprehensivel
y examined and compared. Recent life events were retrospectively exami
ned by interviewing next of kin using a 32-item Recent Life Change Que
stionnaire. Life event data was available on 25 bipolar and 56 unipola
r cases. In about two-thirds of both bipolar (64%) and unipolar (66%)
victims, at least one life event was reported to have occurred during
the last 3 months and in 42% of both groups during the final week. The
events of bipolar victims were more commonly classified as possibly d
ependent on their own behaviour (bipolars 88% vs. unipolars 63%, P = 0
.004). Among bipolars, more males than females had had recent life eve
nts (males 86% vs. females 37%, P = 0.03). The majority of completed s
uicides in both bipolar and unipolar affective disorders seem to be as
sociated with recent psychosocial stress; however, the stressors are c
ommonly likely to be dependent on the victim's behaviour.
