We investigated the association between excessive video game/Internet use and teen suicidality. Data were obtained from the 2007 and 2009 Youth Risk Behavior Survey (YRBS), a high school-based, nationally representative survey (N = 14,041 and N = 16,410, respectively). Teens who reported 5 hours or more of video games/Internet daily use, in the 2009 YRBS, had a significantly higher risk for sadness (adjusted and weighted odds ratio, 95% confidence interval = 2.1, 1.7–2.5), suicidal ideation (1.7, 1.3–2.1), and suicide planning (1.5, 1.1–1.9). The same pattern was found in the 2007 survey. These findings support an association between excessive video game and Internet use and risk for teen depression and suicidality.
