The relation between viewing television coverage of a mass disaster and the development of posttraumatic stress disorder (PTSD) is poorly understood. A cohort of New Yorkers without baseline probable PTSD (N=1787) was assessed 1 year following the September 11, 2001, attacks. The primary outcome was new-onset probable PTSD assessed through a validated scale, and the primary exposure was number of hours of September 11 anniversary news coverage viewed. A total of 99 (5.6%) of participants had developed probable PTSD at the 1-year follow-up. Watching 12 or more hours of September 11 attack anniversary news coverage was associated with a 3.4-fold increased risk of new-onset probable PTSD (p=0.004). Exposure to television coverage of the September 11 anniversary was associated with new-onset probable PTSD among a cohort of New Yorkers with no probable PTSD at baseline.
观看大规模灾难的电视报道与创伤后应激障碍（PTSD）的发生之间的关系尚不清楚。在2001年9月11日袭击事件发生一年后，对一组无基线PTSD可能性的纽约人（N = 1787）进行了评估。主要结局是通过有效量表评估的新发PTSD可能性，主要暴露因素是观看9月11日周年新闻报道的时长。在1年随访时，共有99名（5.6%）参与者出现了PTSD可能性。观看12小时或更长时间的9月11日袭击周年新闻报道与新发PTSD可能性风险增加3.4倍相关（p = 0.004）。在一组基线时无PTSD可能性的纽约人中，接触9月11日周年电视报道与新发PTSD可能性相关。
