Children Who Are Bullied Have Poorer Mental Health

A 2017 study of twins between the ages of 11 and 16 found that being bullied around age 11 caused anxiety, depression, hyperactivity and impulsivity, inattention, and conduct problems, some of which lasted for years. Participants recorded their experiences with physical or verbal bullying, social manipulation, and property attacks (trying to break one’s belongings, for example).

The effects of bullying decreased over time. The bullied children were still significantly more anxious than their non-bullied twins two years later, but this difference faded by the five-year mark. However, paranoid thoughts and cognitive disorganization did persist for 5 years.
The twin study design helped researchers zone in on the causal effect bullying might have on the children’s mental health, rather than other factors the twins shared, such as genetics or family environment. The study included 11,108 twins born in England and Wales.

The research by Timothy Singham and colleagues was published in the journal JAMA Psychiatry. Interestingly, the researchers found that prior mental health difficulties increased children’s likelihood of being bullied, such that being bullied could be considered a symptom of preexisting vulnerabilities. Singham and colleagues suggest that in addition to interventions to reduce bullying and address familial factors that might make children susceptible to bullying, children should also be taught resilience skills.
