Abstract
Several studies relate antisocial and aggressive behavior in adolescents. This work explores the relationship between aggression in bullying and other antisocial behaviors and analyzes de differences among bullying roles. A sample of 1239 Secondary School pupils from the Region of Murcia (Spain) completed an adaptation of the Drugs State Scale (ESTUDES) and the BULL-S Test for the sociometric evaluation of aggressiveness among pupils. Around 30% of the sample indicated that had consumed some type of drug and there were no differences by gender and more than 50% made some kind of dissocial behavior. Significant differences were found among the roles in bullying, highlighting a positive correlation among bully pupils, consume and antisocial behaviours. Those behaviours were related to personal, scholar and family risk actions as driving under alcohol effects, taking part in fights, being arrested by the police, running away from home for more than a full day or being thrown out of school for a full day or more. Meanwhile “having a conflict or an important quarrel with parents or siblings” do not showed significant differences. There were differences in the type of drug consumed between aggressors and victims.
