Risk Factors for Youth Violence

When we say that something is a "risk factor" for youth violence, we mean that when that factor is present, a child is at greater risk for becoming violent. Risk factors can be characteristics of the individual child, the child's relationship with family or peers, the child's school, or the child's environment.

Risk factors for youth violence include:

Typically, the more risk factors present in a child's life, the higher the likelihood that a child or teen will tend to act aggressively. Different risk factors take on a greater or lesser importance at different stages of a child's life. While family factors appear to play an important role in the development of aggression in young children, the role of friends and peers becomes much more crucial during the teen years.[10]

Although many children are exposed to one or more of these risk factors, only a small number of children become highly aggressive. Researchers have proposed a number of "protective factors", such as a commitment to school and a positive relationship with a supportive adult, which may shield children and teens from developing aggressive behavior, even in the presence of a number of risk factors.[11] Interventions that seek to increase protective factors and reduce risk factors can significantly reduce aggressive behavior in children and teens.

Researchers have identified a number of factors that increase children and teens' risk for becoming involved in serious violence during the teenage years. For children under 13, the most important factors include: early involvement in serious criminal behavior, early substance use, being male, a history of physical aggression toward others, low parent education levels or poverty, and parent involvement in illegal activities.[12]

Once a child becomes a teenager, different factors predict involvement in serious violence. Friends and peers are much more important for teens, and friendships with antisocial or delinquent peers, membership in a gang, and involvement in other criminal activity are the most important predictors of serious violence for teenagers.[13]

Teens that commit acts of serious violence are often involved in other types of criminal behavior and often live a lifestyle that involves a number of risky behaviors, including using drugs, carrying weapons, driving recklessly, and having unsafe sex.[14]
