Researchers have been studying bullying and its effects over many years. One of scientists’ main concerns has been whether bullying predicts violence and aggression later in life. For this reason there have been many studies conducted to see how bullying affects bullies and their victims over time.

In 2012, Maria M. Ttofi, David P. Farrington, and Friedrich Losel found a link between school bullying (bullies and their victims) and aggressive and violent behavior later in life. This study found a consistent link between bullying and bully victimization and later violence. This study also found that the younger children are when they exhibit bullying behaviors, the more likely they are to have incidences of assault, weapon charges, robbery, battery, as well as fight, be defiant, argumentative, and cruel later in life.

Past research studies have shown adults criminals, with violent offenses, often have school records of aggressive behavior and bullying. Bullying at school was found to predict criminal offensive up to six years later and victims of bullies have been found have a higher likelihood of offending later in life than those who were not bullied.  Furthermore, bullies are more likely to become depressed later in life than those who did not bully others and those who were victimized were more likely to suffer from depression up to seven years later.

Statistics show 1 in 3 k-12 grade students is either a bully or the victim of a bully. Based on the frequency of bullying activity and the study findings, there is a need for prevention intervention programs throughout schools to offset these negative effects for both bullies and their victims later in life.  Parents can also be proactive by communicating with their children to help reduce the harmful effects of bullying on their child.
