A study completed by researchers at Arizona State University tracked students over more than a decade to analyze how bullying impacted academic achievement and school engagement. They found that students who were chronically bullied were more likely to suffer academically, highlighting the need for more anti-bullying school programs, as well as parental awareness of bullying.
“Children who suffered chronic levels of bullying during their school years (24 percent of sample) had lower academic achievement, a greater dislike of school and less confidence in their academic abilities. Children who had experienced moderate bullying that increased later in their school years (18 percent) had findings similar to kids who were chronically bullied. However, children who suffered decreasing bullying (26 percent) showed fewer academic effects that were similar to youngsters who had experienced little or no bullying (32 percent), which revealed that some children could recover from bullying if it decreased. Boys were significantly more likely to suffer chronic or increasing bullying than girls.” (American Psychological Association)
