Purpose. Firesetters have traditionally been considered dangerous repeat offenders.
However, the specific risk factors associated with firesetting recidivism have not been
consistently tested in representative samples. It is also unclear whether individuals whose
offending is limited to firesetting are at increased risk of reoffending when compared with
firesetters who have more versatile offending. This study aimed to: (I) determine the rate
of firesetting recidivism in a representative sample of firesetters before the courts; and (2)
determine the psychiatric and criminogenic factors that are related to firesetting
recidivism.
Methods. The study employed a data linkage approach to examine the psychiatric and
criminal histories of 1052 firesetters convicted of arson between 2000 and 2009 in Victoria,
Australia. The characteristics of those who reoffended, over a follow-up period of 2.5-
1 I years, by committing arson and arson-related offences were compared with those who
went on to reoffend in other ways but not arson. An improper model was used to
determine which of the tested variables could meaningfully predict firesetting recidivism.
Results. The rate of firesetting recidivism, based on charges, was very low (5.3%)
compared with the rate of general recidivism (55.4%); the vast majority of firesetting
recidivists were mixed (criminally versatile) offenders (91 %). The study found thatgeneral
criminality, firesetting history, and psychiatric disorder were associated with firesetting
recidivism.
Conclusions. When assessing risk of firesetting recidivism, clinicians need to consider
general criminality in addition to fire-specific history, and the potential impacts of mental
disorder on recidivism.
Despite its human and fiscal costs, and a relatively long history of research, arson remains
one of the least understood criminal behaviours, particularly with regard to reoffending
(Davis & Lauber, 1999). Given the lack of information about factors related to repeat
firesetting, it has been suggested that there may not be a simple formula to identify those
who commit further arson offences (Soothill & Pope, 1973). Even if such a formula could
be derived, the existing literature lacks the consistency required to identify valid risk
factors related to recidivistic arson with any confidence (Davis & Lauber, 1999).
