The study looked at how children think about worrying and how it affects them. They found that children who have negative beliefs about worry and avoid thinking about their problems are more likely to worry a lot. Parents who worry a lot themselves can also make their children worry more. Children who have trouble with uncertainty and negative thinking are more likely to worry. This shows that children's thoughts and their parents' worries can influence how much a child worries. It suggests that helping children change their negative beliefs and avoidant thinking could be important in reducing worry.
