On 9/11, the United States was faced with one of its greatest tragedies. Many people were directly exposed to this massive traumatic event. Others were indirectly exposed through the extensive television coverage and/or stories from survivors of the attacks. As a result of this, many people were put at risk for the development of PTSD.

Rates of PTSD After 9/11

Several studies have been published that examined rates of PTSD as a result of the 9/11 terrorist attacks. Another study of 998 adults in New York City five to eight weeks after the attacks found that 7.5% had PTSD.

How Distance Made a Difference

As would be expected, people who were in closer proximity to the attacks have been found to have higher rates of PTSD. In particular, 20% of people who lived below Canal Street in New York City (which is close to the World Trade Center) were found to have PTSD following the attacks.

Rates of PTSD in Relief Workers

Another study looked at 109 mental health relief workers who went to Ground Zero for one week during the first 2 months after the 9/11 attacks. This study found that relief workers showed signs of PTSD as a result of direct and indirect exposure to traumatic events at Ground Zero.

Long-Term Impact of 9/11

Despite the high rates of PTSD immediately following the 9/11 attacks, studies are showing that many people are resilient, no longer having PTSD symptoms as soon as 6 months after the event. However, if you have been exposed to a traumatic event and find that you are continuing to experience PTSD symptoms or other psychological difficulties (for example, depression), it is very important for you to seek help. The Anxiety Disorder Association of America provides links to therapists across the United States who specialize in the treatment of anxiety disorders and PTSD specifically. Lists of anxiety disorder support groups being offered across the United States are also provided. The National Center for PTSD also offers resources and help to locate mental help services near you.
