The study has some flaws. The parents weren’t told the purpose of the study, but the authors concede they probably figured it out and that might have affected the results.
Before the study, the children averaged about 1½ hours of TV, video and computer game watching a day, with violent content making up about a quarter of that time. By the end of the study, that increased by up to 10 minutes. Those in the TV coaching group increased their time with positive shows; the healthy eating group watched more violent TV.
Nancy Jensen, who took part with her now 6-year-old daughter, said the study was a wake-up call.
“I didn’t realize how much Elizabeth was watching and how much she was watching on her own,” she said.
Jensen said her daughter’s behavior improved after making changes, and she continues to control what Elizabeth and her 2-year-old brother, Joe, watch. She also decided to replace most of Elizabeth’s TV time with games, art and outdoor fun.
During a recent visit to their Seattle home, the children seemed more interested in playing with blocks and running around outside than watching TV.
Another researcher who was not involved in this study but also focuses his work on kids and television commended Christakis for taking a look at the influence of positive TV programs, instead of focusing on the impact of violent TV.
“I think it’s fabulous that people are looking on the positive side. Because no one’s going to stop watching TV, we have to have viable alternatives for kids,” said Dr. Michael Rich, director of the Center on Media and Child Health at Children’s Hospital Boston.
