Corresponding author Hannah Lantos, a youth development expert at Child Trends, a non-profit research organization in Bethesda, Maryland, USA said: "Maltreatment and experiences of violence have been shown to impact children's wellbeing long into the future, and there is a risk of a link between experiences of maltreatment and engagement in delinquent behaviors in childhood and adolescence. Our research suggests that many young people involved in the juvenile justice system are struggling with the effects of trauma and earlier maltreatment, and that we should provide support for youth who have experienced maltreatment to engage in more pro-social behaviors."

'Delinquent behavior' refers to behaviors in young people under the age of 18 that would constitute criminal offenses if committed by adults, such as damaging another person's property or stealing, shooting or stabbing someone, using a threatening weapon to get something from someone or being in a fight.
