We investigated psychiatric and demographic variables and lifetime criminality among arsonists referred for a pre-trial psychiatric assessment. The medical and criminal records of 282 arsonists were studied in order to compare first-time and repeat offenders with regard to diagnostic, demographic and biological variables. Alcohol dependence and antisocial personality disorder were common among recidivist offenders. This finding was especially prominent among offenders who committed violent crimes. Recidivist offenders commonly had a history of long-lasting enuresis during their childhood. They were younger at the time of their first offence, and were more often intoxicated with alcohol during the arson attempt. Among arsonists, lifetime criminal recidivism was primarily associated with alcohol dependence and antisocial personality disorder. Psychosis was a common diagnosis among subjects who had no record of recidivist criminal offences.
