A Modelization of Differences between Early- and Late-Starter French-Canadian Offenders

Abstract

Objective. Recent research has shown that there are two groups of mentally disordered offenders: early starters (early onset of behavioral problems) and late starters (behavior problems that start in adulthood). The present study sought to arrive at a better understanding of the differences between persons suffering from major mental disorder who are early- and late-starter offenders. Method. The sample was recruited within the province of Quebec, Canada. It is composed of 137 men diagnosed with a major mental disorder. Participants were recruited under three distinct legal statuses. Results. Results indicate that there are interesting and key differences between early and late starters on etiological and symptomatological variables, as well as in terms of antisocial behaviors. Conclusion. These findings have implications for the treatment, prevention, and risk assessment of persons with major mental disorders.
