Impact of Bullying Lessens Over Time — Resiliency Important
A new study from the UK confirms that bullying can influence the development of anxiety and depression years later. However, University College London investigators also found that the detrimental effects of bullying decreased over time, which the authors say shows the potential for resilience in children exposed to bullying.
“Previous studies have shown that bullied children are more likely to suffer mental health issues, but give little evidence of a causal link, as pre-existing vulnerabilities can make children both more likely to be bullied and experience worse mental health outcomes. We used a robust study design to identify causation,” said the study’s lead author, Dr. Jean-Baptiste Pingault (UCL Psychology & Language Sciences).
The study appears in the Journal of the American Medical Association — Psychiatry (JAMA-Psychiatry).
“While our findings show that being bullied leads to detrimental mental health outcomes, they also offer a message of hope by highlighting the potential for resilience. Bullying certainly causes suffering, but the impact on mental health decreases over time, so children are able to recover in the medium term,” said Dr. Pingault.
The study involved 11,108 participants from the Twins Early Development Study (TEDS), which is based at King’s College London. By surveying twins, researchers were able to look at the associations between bullying and mental health outcomes, and then account for the confounding effects of their genes and shared environmental influences.
The comprehensive evaluation was made possible by the study of both monozygotic (“identical”) twins who have matching genes and home environments and dizygotic (“non-identical”) twins, who don’t share all of their genes, but have matching home environments.
Both children and their parents filled out questionnaire: at age 11 and 14 they were asked about peer victimization, and at 11 and 16 they were asked about mental health difficulties.
The effect sizes were stronger before controlling for shared environmental factors and genetics, confirming that bullying itself is only partly to blame for the poor mental health outcomes experienced by bullied children.
The researchers found that once confounding factors were removed, there was proof of a cause and effect between bullying and concurrent anxiety, depression, hyperactivity and impulsivity, inattention, and conduct problems.
Two years later, the impact on anxiety persisted. Five years later, there was no longer an effect on any of those outcomes, but 16-year-olds who had been bullied at age 11 remained more likely to have paranoid thoughts or cognitive disorganization (a tendency for thoughts to become derailed).
“While our findings show that being bullied leads to detrimental mental health outcomes, they also offer a message of hope by highlighting the potential for resilience. Bullying certainly causes suffering, but the impact on mental health decreases over time, so children are able to recover in the medium term,” Dr. Pingault said.
“The detrimental effects of bullying show that more needs to be done to help children who are bullied. In addition to interventions aimed at stopping bullying from happening, we should also support children who have been bullied by supporting resilience processes on their path to recovery. Our findings highlight the importance of continuous support to mental health care for children and adolescents,” he said.
Dr. Sophie Dix, Director of Research at MQ: Transforming Mental Health said, “This important research is further strong evidence of the need to take the mental health impacts of bullying seriously. We hope this study provides fresh impetus to make sure young people at risk — and those currently being bullied — get effective help as soon as possible.”
“ …..this unprecedented study gives the strongest evidence to date that bullying can directly cause many common mental health conditions — and have a serious effect on mental health in the long-term. But the good news is that it shows that people can and do get better — demonstrating the importance of resilience. Now we need to understand why this is and develop new ways, through research, to intervene and change lives,” she said.
