Among police responders enrolled in the World Trade Center Health Registry (WTCHR), Post-traumatic Stress Disorder (PTSD) was almost twice as prevalent among women as men 2-3 years after the 9/11 attacks.
Police participants in the WTCHR Wave 1 survey 2-3 years after 9/11/01, were reassessed for probable PTSD at Wave 2, 5-6 years after 9/11/01, using PCL DSM-IV criteria.
Police participants in the Wave 2 survey included 2,527 men, 413 women. The prevalence of "Probable PTSD" was 7.8% at Wave 1 and 16.5% at Wave 2. Mean PCL scores increased from 25.1 to 29.9 for men and 28.6 to 32.2 for women. Prevalence of PTSD was higher for women than for men at Wave 1 (χ(2) = 10.882, P = 0.002), but not Wave 2 (χ(2) = 2.416, P = 0.133). Other risk factors included losing one's job after 9/11 and being disabled.
Prevalence of probable PTSD among police doubled between 2003-2004 and 2006-2007. After the 2-year time span, the gender difference was no longer significant; prevalence of PTSD symptoms increased and there was a substantial amount of co-morbidity with other mental health problems. Further development of prevention and intervention strategies for police responders with symptoms of PTSD is needed. The observed upward trend in PCL scores over time in police officers with PCL scores less than 44, suggests that PTSD prevention and intervention strategies should be applied to all police affected by the 9/11 attacks, not limited just to those with PTSD symptoms.
在世贸中心健康登记处（WTCHR）注册的警察响应者中，9/11 袭击后 2-3 年，女性患创伤后应激障碍（PTSD）的比例几乎是男性的两倍。
2001 年 9 月 11 日之后的 2-3 年，WTCHR 波 1 调查中的警察参与者使用 PCL DSM-IV 标准在波 2（2001 年 9 月 11 日之后的 5-6 年）重新评估可能的 PTSD。
波 2 调查中的警察参与者包括 2527 名男性和 413 名女性。波 1 时“可能的 PTSD”的患病率为 7.8%，波 2 时为 16.5%。男性的 PCL 得分从 25.1 增加到 29.9，女性从 28.6 增加到 32.2。波 1 时女性的 PTSD 患病率高于男性（χ(2) = 10.882，P = 0.002），但波 2 时并非如此（χ(2) = 2.416，P = 0.133）。其他风险因素包括 9/11 后失业和残疾。
2003-2004 年至 2006-2007 年期间，警察中可能患有 PTSD 的比例增加了一倍。在 2 年的时间跨度之后，性别差异不再显著；PTSD 症状的患病率增加，并且与其他心理健康问题有大量合并症。需要进一步制定针对有 PTSD 症状的警察响应者的预防和干预策略。在 PCL 得分低于 44 的警察中，PCL 得分随时间的上升趋势表明，PTSD 预防和干预策略应应用于所有受 9/11 袭击影响的警察，而不仅仅是那些有 PTSD 症状的警察。
