With a government review underway, we have to ask why children bully other kids

Though of course, even being bullied for a short time can still be damaging and traumatic for the student on the receiving end.

This could suggest there is a developmental phase in bullying as most bullying occurs between children in Year 6 through to Year 10.

However, there are those students who persistently bully others and these are the students whose behaviour remains a problem despite interventions and prevention approaches.

Who is more likely to bully?

There are certain personality types who are more likely to persistently bully others. These include:

• students with defensive personalities. This means they think very highly of themselves and actively seek attention but can't take criticism

• students with narcissistic personalities, who are likely to become aggressive when their egos are threatened

• students who are emotionally unstable.

But research is mixed on the question of self-esteem. Some researchers say children who bully have high self-esteem, yet others have found they have low self-esteem.

There are many reasons why a child might develop the personality traits that would lead them to bully.

Physical abuse in childhood can play a role. There is an association between a child being exposed to domestic violence at home and then bullying their peers.

Parenting can also be a factor. For example, being overvalued but not well disciplined by parents can lead to higher traits of narcissism and a greater likelihood a child will bully.

What can we do?

Children who persistently bully may require targeted and nuanced approaches. Current approaches emphasise restoring positive relationships, rather than punishments or sanctions.

One approach is individual motivational interviewing. Here a school counsellor shows young people they can achieve their goals by other means. This encourages perpetrators to see there are more benefits in not bullying than in bullying. For example, "I want to be popular. But if I bully, I also make other kids scared of me and not want to hang around me."

More broadly, schools can also teach explicit programs on social and emotional learning.

These programs focus on emotional intelligence and emotional literacy, enabling students to recognise and manage their emotions, understand the perspectives of others and have positive relationships with peers.

Schools which respect the diversity of students, are also better placed to address bullying. If all students have opportunities to participate in learning, it will develop their sense of belonging to their school community. This not only decreases rates of bullying but supports students who have been victimised.
