Drs Wessely and Castle state that the relationship between the major mental disorders and crime is controversial. We do not share their opinion. As we noted in our article,1 there is compelling evidence from 3 different types of studies that has accumulated over the past 20 years to indicate an association between the major mental disorders and criminality and violence. The findings from 3 Scandinavian birth cohorts, from follow-up studies of patients discharged from inpatient wards to the community in both Scandinavia and North America, and from investigations of the prevalence of major mental disorders among incarcerated offenders and homicide offenders in several countries all support our contention.
