-The biology of violence and the environment that breeds violence.
-The psychology of the young victim and the victim.
Self-treatment and should be kept in mind as in other areas of violence that the cause is multifactor. In connection with the family we could say that the combination of lax discipline and hostile attitude on the part of both parents encourage strong and very controlled aggressive behaviour of children. When parents or teachers often require different methods of punishment, while it is negative and hostile then led to the creation of aggressive behaviour. These methods are often a demonstration effect. Parents demonstrate and hold the power, mainly by exercising authoritarian control and using corporal punishment, harsh and ugly words, threats and deprivation of rights. Of course we must not forget that the family and society are systems that affect the adolescent, the adolescent and acts as spokesperson of the problem which the system represents. This can rotate in roles from victim to victim, but are both expressions of weakness which makes them to discharge that others refuse. A large reason is for exposure to scenes of violence in the media and the development of these standards. This report may help to speak and a pre-existing background of violence. The modern biologists’ talk of gene differentiation is likely to create a more receptive temperament to antisocial behaviour. At times there have been theories of even the shape and profile of the head and body. Others have spoken and showed theorists investigations influenced by biochemical factors that affect the central and autonomic nervous system. Connections can be made with blood sugar levels and learning dysfunctions. At an individual level is important to put the debate the meaning of personal and social control, for example how well the adolescent has learned to resist the use of non-social methods to reach the objective. The emotional conversation and the transfer of emotion teenager learn the needs but also to withstand cancellations when something is not done. When the place gets some abuse from an adult or another teenager then this is likely to recur as a workaround to have learned from the model is behaviour. The teenager in connection with the child creates a sense of identity and autonomy that must be defended. This creates great stress in the same one and so far other was responsible for this. Where are the social and professional influences in the adult, the teenager added the influence of sub groups that own and those owned by not belonging. Whether it is one victim or the victim may depend on many factors related to socioeconomic status of the family of the individual and even national origin. The transformation of child to adult is an intensive course which is expressed and managed differently from person to person. If the teen has been trained to withstand the emotions but also to recognize as his own and to protect himself delimiting their peers, but also requesting assistance from larger, then it might not belong to any of the above two categories. It is clear that it is very easy to regain the lost control of the victim and to expiate the guilty of victim it can be moved from one position to another. Finally, there are cases of self-direct or indirect, behaviour and self suicide which roles exist. All the above accompanied by feelings of inability in doing something , pain and sense of helpless. Therapeutic interventions can be made to systems owned by the teenager, school, community, family and society as hyper systems and the same person. These aim to cure the wound that has been created with the psycho education to tackle difficult situations. On the other hand, the expert must know the adolescent to recognize the signs of his body and the thoughts that make and cause anger. This helps to replace the methods of aggression and anger management. Of course treatment should be another way to put the teenager in the role of the patient, which is itself victimization.
