Background: The study set out to review the relationship between mental disorder and fire-setting.
Method: Sociodemographic, psychiatric, and medical data were retrospectively obtained from case notes of a group of 36 fire-setters referred to the North West Thames Forensic Psychiatry Service over a four-year period.
Results: Of the sample, 28% were female and one-third had no mental illness; 28% had a previous medical history of possible relevance. Psychoactive substance abuse was common. There was a significant disturbance of interpersonal relationships. Eighty-five per cent lived alone, and 44% of the female fire-setters had a history of sexual abuse.
Conclusion: On the basis of this study, a multiaxial classification system of fire-setting is proposed.
