A comparison of psychopathology and reoffending in female and male convicted firesetters.

Little is known about the psychopathological or criminal history characteristics of female firesetters, or how often women reoffend by firesetting. The current study is one of the few large-scale longitudinal investigations to compare key psychiatric and offending variables in female and male firesetters who are not incarcerated or known to be mentally disordered. In addition, the study aimed to identify the base rate of recidivism for female firesetters compared with males. The study compared all 143 female and 909 male firesetters convicted of arson and fire-related offenses between 2000 and 2009 in Victoria, Australia. The study employed a data linkage approach to compare the psychiatric and criminal histories of participants and reoffending in the sample. Firesetters of both sexes reoffended by firesetting at similar rates (males 5.1%, females 7.0%), and reoffenders shared many characteristics. Compared with male firesetters, female firesetters were found to be less criminally versatile, to have offended less overall, and were less likely to have violent offenses. Females were more often diagnosed with depression, substance misuse, and personality disorder than men. The findings indicate that female firesetters might be suitable for assessment approaches and treatment programs offered to men, but tailored to take account of the personality and psychopathological characteristics seen more often in this group.

Mental illness and psychiatric treatment amongst firesetters, other offenders and the general community.

OBJECTIVE: Firesetting is often reported to be associated with psychopathology, but frequently these conclusions are based on studies reliant on selective forensic psychiatric samples without the use of comparison groups. The aim of the study was to examine the rates of mental illness, substance use disorders, personality pathology and psychiatric service usage in a population of convicted firesetters compared with other offenders and community controls. METHOD: Using a data-linkage design, the study examined the psychiatric histories and usage of public mental health services by 1328 arsonists convicted between 2000 and 2009 in Victoria, Australia. These were compared with 1328 matched community controls and 421 non-firesetting offenders. RESULTS: Firesetters were significantly more likely to have been registered with psychiatric services (37%) compared with other offenders (29.3%) and community controls (8.7%). The firesetters were also more likely to have utilised a diverse range of public mental health services. Firesetters attracted psychiatric diagnoses more often than community controls and other offenders, particularly affective, substance use, and personality disorders. CONCLUSIONS: This study confirms that there is a link between firesetting and psychopathology, suggesting that there is a role for the psychiatric screening of known firesetters, and a need to consider psychopathology in formulating the risk for further firesetting.
