The effects of intense consumption of violent media on the violent behavior of children and adolescents have been controversially discussed for years. This volume examines the long-term effects of consuming violent media (films and video games) on the attitudes towards violence and violent behavior of adolescents using panel data. It also analyzes whether different parenting styles have a pro-violent effect that can be exacerbated by the consumption of violent media. In addition to multiple group comparisons, structural equation models with latent interaction terms are also calculated. The results indicate that the consumption of violent media, alongside and independently of parenting, alters the violent attitudes of adolescent consumers. Mediated through a stronger endorsement of violence, the consumption of media violence tends to lead to increased violent behavior as well.
