Sept. 11 distress lingers at Pentagon, researchers find

WASHINGTON – Researchers studying the emotional aftermath of the Sept. 11, 2001, attack on the Pentagon reported this week that depression and post-traumatic stress remained significant two years later in an office of military and civilian employees who lost two dozen of their colleagues.

The degree of continuing psychological upheaval was greatest among those who were injured that horrific morning, when a commandeered American Airlines plane was crashed into the Pentagon’s western flank, killing 184 people on the flight and on the ground.

But even among those not physically harmed, more than one in six were still struggling to cope – an indication that their distress had settled into a chronic pattern.

The research illustrates the “enduring impact of terrorism” and will help doctors identify the types of individuals at greatest risk for mental health problems in the event of future strikes, the authors said.

“Leaders in government and business, as well as disaster medical planners, should ensure that high-risk populations … have long-term access to mental health services,” they concluded.

The study was presented at an international conference on military medicine being held this week in Crystal City, Va., just days after the third anniversary of Sept. 11. Led by psychiatrist Thomas Grieger of the Center for the Study of Traumatic Stress – part of the Uniformed Services University of the Health Sciences in Bethesda, Md. – it builds on previous surveys of other Pentagon employees at seven and 13 months after the attack.

The latest examination focused on a management office at the Pentagon that lost more than 10 percent of its staff on Sept. 11, 2001, and then dealt with major relocation and reorganization issues. The office was not identified, in keeping with standard privacy practices in research.

“This particular work group was hit particularly hard,” Grieger said. In the weeks after the attack, its staff was provided with extensive mental health services, and many availed themselves of the help. Nearly three-quarters of the workers suffering from depression or post-traumatic stress disorder sought care at least once during the two years, and a third remained in treatment during the second year.
