Suicide among personality-disordered offenders: a follow-up study of 1943 male criminal offenders.
Suicide mortality among all male criminal offenders in Sweden who had been subjected to a major forensic psychiatric examination 1988-1991 (n = 1943) was studied, with special reference to offenders with personality disorders. The cohort was followed until the end of 1995. Altogether 135 individuals (6.9%) died during the follow-up period; the mode of death was suicide in 50 individuals (2.6%). The unadjusted suicide mortality ranged from 2.8% among those with personality disorders to 6.1% among those with drug-related psychosis. The standardised mortality ratio (SMR) among personality-disordered offenders was 1212, i.e. around 12 times that of the general population. Survival analyses by means of Cox regression models were performed to identify background factors associated with completed suicide. No specific principal diagnosis showed significantly increased risk for completed suicide. However, concomitant depression and drug abuse were significantly linked to suicide. Violent crime showed no association. Among personality-disordered offenders suicide methods did not differ from those of suicide victims in the general population. There was no association between violent index criminality or between life-time violent criminality and choice of a violent suicide method.
