Bullying and victimization is a worldwide recognized problem for many children and adolescents. It may cause several long-term mental health issues and behavioral issues. Being involved in bullying is not a random event and can be predicted by multiple factors. Research indicates that children and adolescents with diagnosed autism spectrum disorder and attention deficit hyperactivity disorder are more likely to be involved in bullying than those without a neurodevelopmental disorder. Involvement in bullying can also be predicted by other individual characteristics and family factors, such as socioeconomic status, negative childhood experiences and special healthcare needs. Some even argue it can be predicted by sex and age. The purpose of this study is to examine the relationship between autism spectrum disorder and attention deficit hyperactivity disorder and the likelihood of being involved in bullying. Data was collected from The National Survey of Children's Health from 2017 which provides data on multiple intersecting aspects of children’s and adolescents lives. Data was analysed from children and adolescents between the ages of six and 17 leaving a total of 15,438 respondents. Multinomial logistic regressions were conducted to identify risk factors of involvement in bullying. Additional regressions examined interactions between autism spectrum disorder and attention deficit hyperactivity disorder and the factors that may affect the likelihood of being involved in bullying. Children and adolescents with autism spectrum disorder, attention deficit hyperactivity disorder, special health care needs and negative childhood experiences were more likely to be involved in bullying as both victims and perpetrators when compared to those who didn't have any of the factors. Also, children and adolescents with guardians with lower socioeconomic status were more likely to be involved in bullying as both victims and perpetrators when compared to those with guardians with higher socioeconomic status. Girls were more likely to be victimized compared to boys but there was no difference in sex in perpetration. The likelihood of being involved in bullying decreased with age. Further, they were more likely to be victimized if they had comorbidity and autism spectrum disorder with special health care needs. Also, they were more likely to be victimized if they were younger with autism spectrum disorder and they were more likely to be perpetrators if they were girls with autism spectrum disorder or if they were younger with attention deficit hyperactivity disorder.
