This article aims to test empirically some of them, with data from a French school survey (ESPAD 1999). The statistical analysis of self-reported deviant activities (predation, violence, drug use) leads to distinguish three deviant profiles: casual predations, casual acts of violence and combination of offences. Casual predations are well explained by social control and opportunities theories, where as casual acts of violence and combination of offences fit better with strain and deviant subcultures theories.
