It is important for parents and people who work with children and adolescents to understand that bullying can have both short- and long-term effects on everyone involved. While most research on bullying has been about children and adolescents who have been bullied, those who bully others are also negatively impacted, as are those who are both bullied and bully others, and even those who are not directly involved but witness bullying.  This fact sheet provides research surrounding the psychological, physical, and academic effects on children who have been bullied.
