U.S. children bullied by peers suffer more anxiety in adulthood than kids abused by adults, study finds

CORBIS/Justin Paget
Bullied children in the U.S. were almost five times more likely to suffer from anxiety than children who were “only” maltreated.

Children who are bullied by their peers are at greater risk of developing mental health problems in early adulthood than those who are physically or emotionally abused by an adult, according to a study published recently in the journal Lancet Psychiatry.

The findings underscore the need for school officials, public health officials and other adults to take peer bullying seriously and to implement policies to reduce its incidence, say the authors of the study.

“Being bullied is not a harmless rite of passage or an inevitable part of growing up,” said Dieter Wolke, the study’s lead author and a professor of psychology at the University of Warwick, in a released statement.

Previous research has shown, of course, that maltreatment by adults (defined as physical, emotional or sexual abuse, as well as neglect and other “severe maladaptive parenting”) and bullying by peers can cause children to grow up to have higher rates of depression, anxiety and other mental health problems.

Wolke and his colleagues wanted to determine if one of these forms of abuse was worse than the other.

Study details

For the study, the researchers examined data on 4,026 British children and 1,420 American children whose families were participating in two ongoing cohort studies (The Great Smoky Mountain Study in the U.S. and the Avon Longitudinal Study of Parents and Children in the U.K.).

The British children were born between April 1991 and December 1992. The American children were born about a decade earlier.

Parents filled out questionnaires about their child’s health and development and about whether the child had been maltreated by an adult or bullied in school. In addition, the parents — and the children — were repeatedly interviewed about abuse and bullying throughout the study. The children also underwent periodic psychological assessments.

Key findings

The study found that among the British children, 8.5 percent reported being maltreated, 29.7 percent reported being bullied and 7.0 percent reported being both maltreated and bullied.

Among the American children, 15.0 percent reported being maltreated, 16.3 percent reported being bullied and 9.8 percent reported being both maltreated and bullied.

Wolke and his colleagues then analyzed the data to assess the risk that maltreatment and/or bullying had on the children’s mental health — specifically, on a higher incidence of depression, anxiety and suicidal tendencies — once they reached young adulthood. The researchers found that in both groups of children, those who were bullied by their peers but not maltreated by adults were more likely to have mental health problems than those who were maltreated but not bullied.

For bullied children in the U.S., the risk was greatest for anxiety. They were almost five times more likely to suffer from anxiety than children who were “only” maltreated.

In Britain, the risk was greatest for depression. Bullied British children were 70 percent more likely to be depressed than children who were maltreated.


The study has several limitations. Most notably, parents and children reported the incidents of maltreatment and bullying themselves. Such self-reports are not always reliable. Parents, in particular, might be disinclined to tell researchers that they have been physically or emotionally abusing their child.

Also, the confidence interval for the finding about the increased risk of anxiety among the bullied U.S. children was very wide (2.0 to 12.0), which makes that result less than robust.

Still, coupled with previous research on bullying, this study’s results have important implications for school officials and public health policymakers, say the study’s authors.

“Being bullied has similar and in some cases worse long-term adverse effects on young adults’ mental health than being maltreated,” Wolke and his co-authors write. “Governmental efforts have focused almost exclusively on public policy to address family maltreatment; much less attention and resources [have] been paid to bullying. … This imbalance requires attention.”

    On the other hand

    Kids who humiliate their bully look back at that episode with great satisfaction even late in life.

    I was bullied by three boys in the 7th grade who didn’t like the Sioux kid at their school. I used to take evasive action down allies, etc., to get home without them seeing me and getting me out in the open.

    But one day they caught me. The one who seemed to dislike me the most came forward and challenged me to fight. I subsequently beat the crap out of him. The other two laughed at their friend for his failure and comforted him as he licked his wounds.

    But then a funny thing happened. The four of us became the best of friends. They were in my wedding party 10 years later and we meet regularly for dinner even today. I think it resulted from mutual respect. They respected me for standing up for myself despite the odds, and I respected them for fighting fair (one-on-one) and holding no grudge afterwards. Is that scenario even possible today? I don’t know.

    The point is, I would like to see a study of how successful confrontations with bullies have led to positive mental health later in life. I suggest we would find that such incidents build confidence and self-esteem in individuals who can recall the incident 50 years later and realize they had nothing to fear but fear itself and how the confrontation can actually had a positive outcome.

    In the debate of fight versus flight, this society has been led to believe that “flight” is the only acceptable response. And that’s not true.

      I compliment you for standing up to a bully. I did the same thing. I was the 90 pound weakling who bloodied up (Joe Biden likes that term) the big fat bully when I was 14. We became friends afterward as well.

      The problem today is that these kids come back with a knife or a gun and all hell breaks loose.

        Ahh, yes…

        the old “90 pound weakling” anecdote. Thank god for Charles Atlas and his Dynamic Tension program.

    So now how about . . . . . .

    children who were bullied by their peers AND abused by adults?

    (Trying to puzzle out how this might fit into the possibility of self-reported questionnaire mismatches.)

    When Your Soul Screams

    I’ve been dealing with anxiety and depression for years – from bullying during my childhood to trauma throughout my life. I’ve recently discovered the book When Your Soul Screams by Jennifer Nidoy. It has given me a new, more beautiful, perspective on my depression and anxiety. It’s available on kindle only right now and it’s $2.99 but it’s incredibly worth it.
