Even though several youth fatal suicides have been linked with school victimization, there is lack of evidence on whether cyberbullying victimization causes students to adopt suicidal behaviors. To investigate this issue, I use exogenous state-year variation in cyberbullying laws and information on high school students from the Youth Risk Behavioral Survey within a bivariate probit framework, and complement these estimates with matching techniques. I find that cyberbullying has a strong impact on all suicidal behaviors: it increases suicidal thoughts by 14.5 percentage points and suicide attempts by 8.7 percentage points. Even if the focus is on statewide fatal suicide rates, cyberbullying still leads to significant increases in suicide mortality, with these effects being stronger for men than for women. Since cyberbullying laws have an effect on limiting cyberbullying, investing in cyberbullying-preventing strategies can improve individual health by decreasing suicide attempts, and increase the aggregate health stock by decreasing suicide rates.
尽管有几起青少年自杀死亡事件与校园受害有关,但关于网络欺凌受害是否会导致学生采取自杀行为,证据不足。为了研究这个问题,我在双变量概率模型中利用网络欺凌法规的外生州年变化和来自青少年风险行为调查的高中生信息,并通过匹配技术补充这些估计。我发现网络欺凌对所有自杀行为都有强烈影响:它使自杀念头增加了 14.5 个百分点,使自杀企图增加了 8.7 个百分点。即使关注的是全州范围内的致命自杀率,网络欺凌仍然导致自杀死亡率显著上升,而且这些影响对男性比对女性更强。由于网络欺凌法对限制网络欺凌有效果,因此投资于网络欺凌预防策略可以通过减少自杀企图来改善个人健康,并通过降低自杀率来增加总体健康存量。
