“…Only a small fraction of the research has assessed longitudinal effects (e.g., Ferguson, Garza, Jerabeck, Ramos, & Galindo, ; Möller & Krahé, ). Furthermore, the limited longitudinal work on this topic has been conducted with adolescents or children (e.g., Adachi & Willoughby, ; Ferguson, Garza, et al., ; Ferguson, Ivory, & Beaver, ; Willoughby, Adachi, & Good, ) rather than young adults, even though video game play is highly prevalent among young adults (e.g., Lenhart, Jones, & Macgill, ). Research is needed, therefore, to examine the longitudinal link between video game play and aggression during the developmental period of young adulthood.…”
