Les éléments entourant le passage à l'acte sous forme de co-délinquance au Québec
First studies related to co-offending are more than a century old. Since this subject has greatly evolved during this time, the approach and the methodology used have been developed to follow the subject’s progression. But it is only in recent years that co-offending is studied through police arrest data and it is this type of data that will be used to meet the main objective which aims to be to determine conditions explaining the use or not to co-delinquency for committing a criminal offense. In addition, to meet our research objective, we opted for structuring a theory of the crime, an approach that had never been used before in studies of co-offending. As a methodology, we used a sample of 9 103 criminal participations, 8 243 separate events and 3 356 individuals and several predictors were analyzed to determine which best explain the co-offending. Age, gender, criminal history, urbanity and type of crimes are all variables that were considered. Urbanity is a novelty in this research, since we identified very few studies have addressed the issue. For the type of crime, we have detailed this variable as no studies on co-offending have done previously (23 categories of offenses). This detail allows us to identify the impact of each offense on the use of co-offending. The results obtained from the logistic regression analyze show that the use of co-offending is mainly due to the crime’s type; some crimes are more propitious to co-offending than others. We also find that other variables analyzed (age, gender, criminal history and urbanity) have little or no impact on the use of co-offending.
