Internet Gaming Disorder and the Incidence of Suicide-related Ideation and Behaviors in College Students

Among 2140 students without suicide ideation at baseline, there were 467 incident cases over 3987.6 person-years.

• Students with Internet Gaming Disorder (IGD) experienced a suicide ideation incidence rate of 179 cases per 1000 person-years.
• In contrast, students without IGD had an incidence rate of 114 cases per 1000 person-years for suicide ideation.
• The incidence rates for suicide plans were 67 per 1000 among IGD students and 39 per 1000 among non-IGD students.
• For suicide attempts, the rates were 15 per 1000 for IGD students compared to 10 per 1000 for non-IGD students.
• IGD was associated with an 83% increased risk of suicide ideation after controlling for various mental health factors.
• Although higher incidence rates of plans and attempts were noted in IGD students, these findings were not statistically significant.
