The purpose of this study was to examine high school students' exposure to television programming with aggressive content and to explore whether consumption of aggressive TV varied by sex and ethnicity. Participants were 472 boys and girls from two high schools, one urban and one suburban. Definitions of both direct and indirect aggression were used to rate TV programs, and the participants' exposure to both was assessed. Analysis yielded a statistically significant effect for sex but not ethnicity as girls watched more TV programs containing indirect aggression. Also, exposure to aggressive TV content peaked in Grade 10 and fell sharply thereafter. The importance of educating adolescents about the images they view is highlighted. Implications for research are discussed.
