As concluded in Steinberg's "Adolescence", children brought up by single parents are more likely to live in poverty and engage in delinquent behavior than those who live with both parents. However, according to research done by Graham and Bowling, once the attachment a child feels towards their parent(s) and the level of parental supervision are taken into account, children in single parent families are no more likely to offend than others. It was seen that when a child has low parental supervision they are much more likely to offend. Negative peer group association is more likely when adolescents are left unsupervised. A lack of supervision is also connected to poor relationships between children and parents. Children who are often in conflict with their parents may be less willing to discuss their activities with them. Conflict between a child's parents is also much more closely linked to offending than being raised by a lone parent.
