Longitudinal study shows negative, compounding effects of bullying
The longer the period of time a child is bullied, the more severe and lasting the impact on a child's health, according to a new study from Boston Children's Hospital published online Feb. 17 in Pediatrics. The study is the first to examine the compounding effects of bullying from elementary school to high school.
"Our research shows that long-term bullying has a severe impact on a child's overall health, and that its negative effects can accumulate and get worse with time," says the study's first author Laura Bogart, PhD, from Boston Children's Division of General Pediatrics. "It reinforces the notion that more bullying intervention is needed, because the sooner we stop a child from being bullied, the less likely bullying is to have a lasting, damaging effect on his or her health down the road."
Bogart and the team collected data for the study by following a group of 4,297 children and adolescents from fifth to tenth grade. The researchers periodically interviewed them about their mental and physical health and their experience(s) with bullying.
The researchers found that bullying at any age was associated with worse mental and physical health, increased depressive symptoms and lower self-worth. Participants who experienced chronic bullying also reported increased difficulties in physical activities like walking, running or participating in sports. Those who experienced bullying in the past and were also experiencing bullying in the present showed the lowest health scores.
