The authors investigated the relationship between the September 11, 2001 terrorist attacks and suicide risk in New York City from 1990 to 2006. The average monthly suicide rate over the study period was 0.56 per 100,000 people. The monthly rate after September 2001 was 0.11 per 100,000 people lower as compared to the rate in the period before. However, the rate of change in suicide was not significantly different before and after the disaster, and regression discontinuity analysis indicated no change at this date. There was no net change in the suicide rate in New York City attributable to this disaster, suggesting that factors other than exposure to traumatic events (e.g., cultural norms, availability of lethal methods) may be key drivers of suicide risk in this context.
作者调查了 2001 年 9 月 11 日恐怖袭击事件与 1990 年至 2006 年期间纽约市自杀风险之间的关系。研究期间的平均每月自杀率为每 10 万人 0.56 人。与之前相比，2001 年 9 月之后的每月自杀率低 0.11 人每 10 万人。然而，灾难前后自杀率的变化没有显著差异，回归不连续分析也表明在这一天没有变化。这场灾难并没有导致纽约市自杀率的净变化，这表明在这种情况下，导致自杀风险的因素除了暴露于创伤性事件（例如，文化规范、致命方法的可用性）之外，还有其他因素。
