Television viewing has been associated with posttraumatic stress disorder (PTSD) symptoms after disasters and traumas; we examined characteristics that may explain this association among New Yorkers after September 11, 2001. Among 2001 respondents to a random-digit dial telephone survey conducted 4 months after September 11, people who viewed more television images in the 7 days after September 11 had more probable PTSD. People in the highest third of viewing had a 2.32 times greater odds of probable PTSD after September 11 compared with people in the lowest third of viewing; after adjustment for explanatory variables, the relative odds of probable PTSD were 1.66. Adjustment for perievent panic accounted for 44% of the reduction in association between television and probable PTSD, suggesting that perievent emotional reactions may play an important role in the television and psychopathology association. Television may merit consideration as a potential exposure to a traumatic event.
观看电视与灾难和创伤后的创伤后应激障碍（PTSD）症状有关；我们研究了可能解释2001年9月11日后纽约人之间这种关联的特征。在9月11日后4个月进行的随机数字拨号电话调查的2001名受访者中，9月11日后7天内观看更多电视图像的人患PTSD的可能性更大。观看量处于最高三分之一的人在9月11日后患PTSD的几率比观看量处于最低三分之一的人高2.32倍；在对解释变量进行调整后，患PTSD的相对几率为1.66。对事件发生时的恐慌进行调整后，电视观看与可能患PTSD之间关联的减少有44%得到了解释，这表明事件发生时的情绪反应可能在电视观看与精神病理学关联中起重要作用。电视可能值得被视为一种潜在的创伤性事件暴露因素。
