American children spend an average of 6 hours and 32 minutes each day using various forms of media. Research has suggested that this high level of exposure has a negative impact on children's attitudes and behaviors. For example, media violence increases aggression in children, especially video games which allows children to be the aggressor and obtain rewards for violent acts against others. In addition, media influences sexual behaviors and attitudes by sending contradictory messages that glamorize sexual activity and disregard the risks of such behaviors. Along with these negative behavioral influences, media also impacts children's health and is linked to the rise of childhood obesity. From 1980 to 2000, rates of children being overweight have doubled, while obesity continually is associated with higher rates of hypertension, asthma, type II diabetes, and cardiovascular disease. The majority of research has found a link between the amount of time children spend watching TV and their body weight. Given that 81% of children age 2-7 use media unsupervised (Kaiser Family Foundation, 1999), parents need to play a more active role in monitoring their children's use of electronic entertainment activities and structuring socialization activities. In this article, we will review behavioral technologies to assist parents in reducing their children's media use.
