'Cascading Effect' Of Childhood Experiences May Explain Serious Teen Violence

Adverse experiences early in life can lead to minor childhood behavior problems, which can grow into serious acts of teen violence, according to new research. This "cascading effect" of repeated negative incidents and behaviors is the focus of an article in the journal Child Development. . . .

The researchers tracked 754 children from preschool through adulthood and documented that children who have social and academic problems in elementary school are more likely to have parents who withdraw from them over time. That opens the door for them to make friends with adolescents exhibiting deviant behaviors and, ultimately, leads them to engage in serious and sometimes costly acts of violence.

The developmental path toward violent outcomes was largely the same for boys and girls . . . .

Dodge and his colleagues in the Conduct Problems Prevention Research Group also found that the cascade could be traced back to children born with biological risks or born into economically disadvantaged environments, both of which make consistent parenting a challenge. They determined biological risk by assessing the temperaments of the children in infancy, based on mothers' reports; those at risk were irritable, easily startled and difficult to calm. These children are more likely to exhibit minor social and cognitive problems upon entering school. From there, the behavior problems begin to "cascade," he said.

"The findings indicate that these trajectories are not inevitable, but can be deflected at each subsequent era in development, through interactions with peers, school, and parents along the way," said Dodge, who is the William McDougall Professor of Public Policy and a professor of psychology and neuroscience at Duke. "Successful early intervention could redirect paths of antisocial development to prevent serious violent behavior in adolescence," Dodge said.

This is something that will take some time to cope with up.
