Individual causes

On an individual level, these may relate to temperament, a predisposition towards violent games, an established diagnosis (or tendency) towards attention deficit hyperactivity disorder, limited problem-solving skills and abilities. In children who tend to be more 'impetuous' and have a 'strong temper' there is a greater likelihood of developing bullying behaviour in the future. Although this is not a certainty, on a statistical level, it has been proved that children who are more impetuous, tend over time to be more aggressive and have manifestations tending towards bullying behaviour: children who love 'contact games', who are perpetually ready to intervene in any situation, who tend not to be very shy. Those, on the other hand, who have a calmer temperament and are described as shy, risk-averse, the classic 'good boy' in a nutshell, will find it more difficult to develop such attitudes. These are obviously percentages: it is more or less probable, but not 'certain' or 'to be excluded'. The propensity towards games and manipulative attitudes also constitutes another predisposition factor to the development of bullying behaviour. Finally, the presence of limited problem-solving competence (that is the ability to find more effective and appropriate solutions in response to the actions performed by the others), can be regarded as a risk characteristic: the subject actually fails to relate adequately with others because he or she does not possess the tools to do so.
