Violence on TV: What happens to children who watch?

“Although past evidence showing causal links between modelling and getting rewarded for violence had an immediate impact on aggressive behavior in 4-year-old children, few studies have investigated long-term risks with antisocial behavior. We studied such risks in mid-adolescence, explained Pagani, who is also a researcher at the Centre de recherche Azrieli du CHU Sainte-Justine. It was ideal to study this question with typically developing middle-class children because, as a population, they have the lowest chances of engaging in aggression and behavior harmful to others.”

Close to 2,000 children

In all, Pagani and her team looked at 963 girls and 982 boys born between the springs of 1997 and 1998 who were enrolled in the Quebec Longitudinal Study of Child Development. Parents reported the frequency of their child’s exposure to violent television content at ages 3.5 and 4.5 years old. Boys and girls then self-reported on several aspects of antisocial behavior at age 15.

The study defines screen violence as anything “characterized by physical aggression, verbal aggression, and relational aggression […] depicting situations that intentionally attempt or cause harm to others.” Children, the study says “are attracted to fast-paced, stimulating violent content, which often features appealing characters like superheroes who commit and are rewarded for aggressive acts, thus increasing the likelihood of exposure.”

The researchers then conducted analyses to examine whether exposure to violent television content at ages 3.5 and 4.5 years predicted later antisocial behavior eleven years later.

The researcher added, “We statistically took into account alternative child and family factors that could have explained our results, to be as close as possible to the truth in the relationships we were looking at.”

Boys stand out

At age 15, for boys only, preschool violent televiewing predicted increases in antisocial behavior. Being exposed to violent content in early childhood predicted later aggressive behaviors such as hitting or beating another person, with the intention of obtaining something, stealing, with or without any apparent reason.

Risks also included threats, insults, and gang fight involvement. The use of weapons is also among the behavioral outcomes predicted by exposure to childhood television violence in this study. No effects were found for girls, which was not surprising given that boys are generally more exposed to such content.

Pagani concluded, “Our study provides compelling evidence that early childhood exposure to media violence can have serious, long-lasting consequences, particularly for boys. This underscore the urgent need for public health initiatives that targets campaigns to inform parents and communities about the long-term risks and empower them to make informed choices about young children’s screen content exposure.”

The entire team of students from Université de Montréal and researchers from the United States and Italy established that, “Parents and communities can play a crucial role in limiting future problems by carefully avoiding young children’s exposure to violent media content.”
