A shove, a taunt or name-calling on the playground or in the hall, away from the eyesight, earshot and authority of the teacher – childhood bullying can involve physical contact, spreading rumors and other negative behaviors committed over and over again to intimidate, humiliate and isolate the receiver of the behavior. A review of national and international research on the issue is finding a family connection to the origins of young bullies. Elizabeth Sweeney, a University of Cincinnati master's degree student in sociology, presented her findings Aug. 3 at the 103rd annual meeting of the American Sociological Association.

Sweeney reviewed research out of England, Germany, Norway, Japan, South Africa and the United States, which she reports lagged behind the European countries in examining the phenomenon of bullying prior to this decade. The majority of the research that she examined involved children between the ages of nine and 16. Sweeney says her review of the literature found that children raised by authoritarian parents – parents who are demanding, directive and unresponsive – are the most prone to act out bullying behavior. On the other hand, there were parallels showing that children raised by nurturing, warm, responsive parents were less likely to bully.

"Children who experience hostility, abuse, physical discipline and other aggressive behaviors by their parents are more likely to model that behavior in their peer relationships," she writes. "Children learn from their parents how to behave and interact with others," Sweeney says. "So if they're learning about aggression and angry words at home, they will tend to use these behaviors as coping mechanisms when they interact with their peers." Her review also found that children from middle-income families were less likely to bully than children from the high and low ends of the family income scale.

She says that while some studies suggest boys are more prone to bullying than girls, others state that it runs equally among the genders, although boys are more likely to act out bullying physically, while girls are more verbal. Sweeney adds that it is the tolerance of bullying that "has served as one of the primary contributors to its persistence and severity." She is advocating research that would delve more deeply into the issues of bullying, including in-depth interviews with children, families and school officials.

Study questions the effectiveness of the current movie-rating system

In a paper published in the August issue of the journal Pediatrics, Dartmouth researchers document the alarming numbers of young adolescents age 10-14 who are exposed to graphic violence in movies rated R for violence. They found that these extremely violent movies were seen by an average of 12.5 percent of an estimated 22 million children age 10-14. One R-rated movie, Scary Movie, was seen by an estimated 10 million children, or about 48 percent of 10-14 year olds.

"Our data reveal a disturbingly high rate of exposure among 10-14 year olds nationally to extremely violent movies," says Keilah Worth, the lead author on the study and a post-doctoral fellow at Dartmouth Medical School and at Dartmouth-Hitchcock Medical Center's Norris Cotton Cancer Center. "In Britain, no adolescent would be admitted to these movies unless they were 18. The R rating in this country is clearly not preventing our young people from seeing them."

Many scientific studies have established the connection between exposure to media violence and aggression and violence in children. For example, playing video games can lead to changes in attitudes and behavior as well as desensitization to actual violence. "We know so much about the harmful effects of exposure to violent media content, but how much exposure children actually get has been largely ignored. Now, we're learning more about the large numbers of kids seeing this material and who they are," says Worth.

For this assessment of exposure to violence in movies, the researchers used data from national telephone surveys of more than 6,500 adolescents age 10-14 in 2003. Out of 532 recent releases, the researchers chose to look at exposure to 40 of the most violent movies. The study also revealed some independent risk factors for exposure: boys, minorities, those with lower socioeconomic status, and those with lower academic performance were all more likely to see extremely violent movies. Black male adolescents were at particularly high risk of seeing these movies. For example, Blade, Training Day, and Scary Movie were seen by 37 percent, 27 percent, and 48 percent respectively of all the adolescents surveyed, compared to 82 percent, 81 percent, and 81 percent of black males.

"No expert in child development would advocate for subjecting children as young as 10 to this level of violence, yet the study shows that such exposure is commonplace in this country," says James Sargent, the senior scientist on this study and a professor of pediatrics at Dartmouth Medical School. "We should re-think the current movie rating system, which has been in place for 40 years, and was designed when kids could only see movies in theaters. Ratings need to be more prominent on all movies, whether they are seen in theaters or purchased in the store, and we need clearer messages to parents. Pediatricians and child advocates should instruct parents to strictly abide by the movie-age guidelines and to closely monitor movie viewing."
