Media violence, family conflict ups aggressive behaviours in teens

Teenagers exposed to violence on TV and high levels of household conflict are at risk of engaging in aggressive behaviours, according to scientists including one of Indian origin. Especially prone to aggressive tendencies are those who also have high levels of impulsivity, according to the study published in the journal Aggressive Behavior.

The research -- an online survey of some 2,000 teens aged 14-17 -- also found that parental monitoring, more so for white teens, help to protect against aggressive behaviour.

"Accounting for all the risk factors we looked at in this study, parental monitoring continued to have a strong protective effect," said lead author Atika Khurana, a professor at the University of Oregon in the US. "It was quite interesting that for adolescents who had high levels of media violence exposure, family conflict, impulsivity and sensation-seeking, parental monitoring still continued to provide a protective effect against aggressive tendencies," Khurana said.

The study sought to provide a nuanced look at the unique and combined role of different risk and protective factors including media violence exposure and parental involvement on adolescent aggression. The survey captured teen viewing of 29 mainstream top-grossing mainstream movies from 2014 and 34 black-oriented movies from 2013 and 2014, as well as the viewing of top 30 television shows in the 2014-15 season for black and non-black adolescents, all of which were coded to account for acts of violence occurring in five-minute increments.

Teens were asked what shows they had watched, how many times they viewed each, and whether they had engaged recently in a physical fight, face-to-face bullying and cyberbullying as measures of aggression. To measure family conflict, the teens were asked if their home life involved criticism, hitting each other, cursing, arguing and throwing things when angry. Teens also replied to questions about how often their parents spent time talking with them, engaging in fun activities, and family meal time. Other questions probed parental supervision of media use, such as restricting and forbidding the viewing of violence and adult content, and parent-led discussions about media violence, which often does not result in consequences, versus the ramifications of violence in real-life.

Impulsivity and sensation-seeking levels were measured using widely-used self-report questionnaires."Media violence is a known risk factor for aggression in adolescents.The purpose here was to see how strong a risk factor it is compared to other risk and protective factors and how it operates in tandem with these factors," she said.

Media violence alone, the researchers concluded, is a strong risk factor for aggression, even when the adolescents were low in all the other risk factors. "The effect is no doubt greater if you also have other risk factors such as family conflict and impulsivity, but it is nonetheless significant even for those at lower risk in other categories," Khurana said. While parental supervision was associated with lower levels for aggression, this study, she said, only captured the self-reporting of adolescents in a single round of data collection.
