We report the prevalence of aborted suicide attempts in which the esse
ntial characteristics are (i) intent to kill oneself (ii) a change of
mind before making an actual suicide attempt and (iii) the absence of
physical injury. The lifetime history of aborted suicide attempts was
assessed by semistructured interview of 733 patients, aged 18-59 years
, who were consecutively admitted to a psychiatric hospital. In the st
udy group, 46% of subjects had made a suicide attempt and 29% had made
at least one aborted attempt during their lifetime. Subjects who had
made aborted attempts were more likely to have made actual attempts. A
pproximately 11% of the subjects in the study group had a history of a
borted attempts of potential high lethality, such as going to a height
in order to jump, or holding a gun to the head. There were no major d
emographic differences between those with and without a history of abo
rted attempts. However, among those with no prior history of actual at
tempts, subjects with depression and a family history of suicide were
more than twice as likely as those without such a history to have made
an aborted attempt. Aborted suicide attempts are a common suicidal be
haviour among psychiatric in-patients. Whether they predict actual att
empts or suicide warrants prospective investigation.
