ABSTRACT
The present study examines family and peer influences on adolescent violent behaviours using data from the Montreal Longitudinal Study. Growth Models suggest that different trajectories of parental practices (monitoring and coercion) and of peer delinquency are associated to the multiple trajectories of violent delinquency. Preliminary analysese suggest strong association between peer delinquency, monitoring, coercion and violent delinquency trajectories. Qualitative and quantitative aspects of the trajectories derived from Latent Class Growth Analysis will be discussed in the light of theories on delinquent peer selection.
