The current study consisted of a content analysis of physical violence in films aimed at adolescents over the past three decades. A total of ninety films (thirty each from the 1980s, 1990s, and 2000s) were included in the sample. Gender and age of the aggressor were also assessed. As a whole, levels of violence decreased from the 1980s to the 2000s. However, this depended on the type of violence portrayed. Specifically, gun violence decreased over the past three decades, but other types of physical aggression (including indirect physical aggression) increased. Moreover, female violence doubled across the same period of time. Violence by teenage characters (as opposed to adults) was portrayed less frequently than expected. The influence of films on adolescent aggression is discussed.
