The observation of mental disorder and dangerousness in arsonists: a contemporary appraisal of changes in Dutch forensic mental health cases

In the Netherlands pre-trial forensic mental health assessments are conducted to examine whether a mental disorder was present at the time of the offence that affected the free will of a person, in which case criminal accountability is considered diminished or absent. This study aims to investigate societal changes over time in forensic mental health recommendations in arson cases. Seventy-two reports of male arsonists assessed in 1950–2010 were included in this study, 36 arsonists were assessed in the first time period (1950–1979) and 36 in the second period (1980–2010). Results show an association between DSM classification and the conclusion on criminal accountability only in the first period and an association between recidivism risk and the forensic mental health recommendation only in the later period. It is concluded that mental disorder was of greater influence on the conclusion on accountability in the first time period, whilst dangerousness played a more important role on the forensic mental health recommendation in the later time period. Our findings reflect a shift from paternalistic principles to principles of risk control and show that societal changes influence the field of forensic mental health.
