Characteristics of low IQ arsonists at psychiatric assessment.

We conducted a retrospective study of arsonists referred for psychiatric assessment and found that 88/202 (43.6%) had an IQ of 85 or below. The low IQ group showed more evidence of childhood temperamental disturbance, and a later pattern of internal problems rather than external factors expressing themselves as fire-setting. This study highlights the likelihood of lifelong, temperamental problems being apparent in childhood, and being predictive and possibly causative of fire setting in people with a low IQ. Better understanding of the distinct characteristics of lower IQ arsonists is essential for improved prevention, treatment and management.

Gender differences amongst adult arsonists at psychiatric assessment.

Reports of gender differences amongst arsonists at psychiatric assessment are not uncommon, however some are based on relatively small samples. A new retrospective study highlighting gender differences could help to confirm or refute the current state of knowledge. The aim of the current study was to examine gender differences amongst a sample of 167 adult arsonists (129 males and 38 females). Information was collected from clinical records on sociodemographic, family background and childhood factors; adult adjustment; fire setting history; motives; features of pyromania and other offending, from the case notes of a group of arsonists referred to the West Midlands Psychiatry Service over a 24-year period. Female arsonists were older than males and more likely to have a psychiatric diagnosis. Women more frequently had a history of sexual abuse, while men had a more varied criminal background and more substance abuse problems. Our findings largely support previous research, and are discussed in this context, whilst also bringing attention to a more recently developed theory (Action System Model). Significant gender differences amongst arsonists indicates that different emphases in the treatment of male and female arsonists may be advisable, though a reliable evidence base for treatment has yet to be established.
