The present study examined the prevalence and comorbidity of mental di
sorders according to DSM-III-R among male and female suicide attempter
s. A systematic sample of 114 patients from consecutive cases of attem
pted suicide referred io a general hospital in Helsinki between 1 Janu
ary and 31 July 1990 was interviewed. In 98% of the cases at least one
Axis I diagnosis was made, Depressive syndromes were more common amon
g females (85%) than males (64%), and alcohol dependence was more comm
on among males (64%) than females (21%). A high proportion of suicide
attempters (82%) suffered from comorbid mental disorders. Comorbidity
appears to play an important role in parasuicide.
