Social and personal risk behaviours are extending behaviours among adolescents. Drugs abuse and problems in family and school relationships stand out among these behaviours, where bullying is detected, every time more, as a social dysfunction. This paper presents (1) the analysis of some social and personal well being risk behaviour among adolescents (N=1239) secondary school pupils, (612 boys and 627 girls) and (2) a context intervention proposal for a class-group (n=27), where bullying were detected performed by 2 bullies, 2 victims and 1 provoke-victim pupils. Findings point out that, more than one in four pupils shows social and health risk behaviour, such as drugs abuse or drive under alcoholics' effects. We did not find differences in drugs consume between boys and girls but boys score higher in other risk behaviours. We also observed high relations among risk behaviours, scholar failure and bullying. Analysis for the intact group-class revealed that bully pupils present a high level of scholar failure and perpetrate other delinquent actions and they find support in their friends and family. The intervention proposal for this group is oriented not only for those pupils involved in bullying, but also for all educative agents.
