The authors investigated trends in probable post-traumatic stress disorder (PTSD) prevalence in the general population of New York City in the first 6 months after the September 11 terrorist attacks. Three random digit dialing telephone surveys of adults in progressively larger portions of the New York City metropolitan area were conducted 1 month, 4 months, and 6 months after September 11, 2001. A total of 1,008, 2,001, and 2,752 demographically representative adults were recruited in the three surveys, respectively. The current prevalence of probable PTSD related to the September 11 attacks in Manhattan declined from 7.5% (95% confidence interval: 5.7, 9.3) 1 month after September 11 to 0.6% (95% confidence interval: 0.3, 0.9) 6 months after September 11. Although the prevalence of PTSD symptoms was consistently higher among persons who were more directly affected by the attacks, a substantial number of persons who were not directly affected by the attacks also met criteria for probable PTSD. These data suggest a rapid resolution of most of the probable PTSD symptoms in the general population of New York City in the first 6 months after the attacks. The psychological consequences of a large-scale disaster in a densely populated urban area may extend beyond persons directly affected by the disaster to persons in the general population.
作者调查了2001年9月11日恐怖袭击事件后最初6个月纽约市普通人群中创伤后应激障碍（PTSD）的可能患病率趋势。在2001年9月11日之后的1个月、4个月和6个月，对纽约市大都市区越来越大范围内的成年人进行了三次随机数字拨号电话调查。在这三次调查中，分别招募了1008名、2001名和2752名具有人口统计学代表性的成年人。与曼哈顿9月11日袭击事件相关的PTSD可能患病率从9月11日后1个月的7.5%（95%置信区间：5.7，9.3）下降到9月11日后6个月的0.6%（95%置信区间：0.3，0.9）。尽管袭击事件直接影响更大的人群中PTSD症状的患病率一直较高，但大量未受袭击事件直接影响的人也符合PTSD可能的标准。这些数据表明，袭击事件后的头6个月里，纽约市普通人群中大多数PTSD可能症状迅速得到缓解。在人口密集的城市地区，大规模灾难的心理影响可能不仅限于直接受灾难影响的人群，还会波及普通人群。
