We thank Ms Afifi and colleagues for their comments. Yes, the children in our study did spend a lot of time watching television, but no more than reported for children in other countries1 and less than children in a recent survey of children in Dunedin, New Zealand (R. McGee, PhD, written communication, August 15, 2005). We don’t think that we should attribute the time spent watching television by the average child to parental neglect or a troubled home environment. Nevertheless, Afifi et al raise an important issue about potential confounding by family and environmental factors in the relationship between television viewing and educational achievement.
