Sept. 11, 2002 Editor’s Note: A longitudinal survey described in the Sept. 11 issue of The Journal of the American Medical Association evaluated risk factors associated with prolonged posttraumatic stress after the terrorist attacks of Sept. 11, 2001.
Surprisingly, risk was not directly associated with exposure to or loss from the trauma, but rather to use of specific coping strategies. This study involved a random sample of the U.S. population living outside New York City who were already participating in an Internet-based survey before the Sept. 11 attacks occurred.
Two months after the attacks, 17% of 933 subjects reported symptoms of posttraumatic stress disorder (PTSD), and 5.8% still reported symptoms at six months.
Lead author and principal investigator Roxane Cohen Silver, PhD, a professor of psychology and social behavior at University of California, Irvine, is an expert on long-term effects of stressful life experiences.
She has extensively studied cognitive, emotional, social, and physical responses to traumatic events, as well as coping responses, societal influences, and other factors that facilitate successful adjustment. She shared with Medscape’s Laurie Barclay some observations gleaned from the longitudinal study concerning responses to the 9/11 terrorist attacks, and suggested how healthcare providers might identify those at risk for poor psychological outcome.
