Children who have been exposed to both 9/11 and another traumatic event were more likely to experience behavioural problems when compared to those who were exposed to none or only one traumatic event.
Young children may be especially vulnerable to the adverse psychological consequences of trauma, according to background information in the article. However, little is known about the effect of terrorism on preschoolers.
AdvertisementClaude M. Chemtob, Ph.D., of the Mount Sinai School of Medicine, New York, and colleagues studied 116 preschool children (average age 3.9) directly exposed to the World Trade Center (WTC) attacks. Between March 2003 and December 2005—an average of 35 months after the attacks—the parents of children who lived or attended preschool in lower Manhattan filled out a questionnaire about their children, providing information on demographics, level of exposure to the attacks, occurrence of other traumatic events (such as the death of a family member, being in a natural disaster or seeing a serious accident) and emotional and behavioral factors.
Of the children participating, 23 percent were exposed to one or more high-intensity WTC events, meaning that they saw the towers collapse, saw injured people, saw dead bodies or saw people jumping out of buildings. Overall, these children had nearly five times the odds of having trouble sleeping and had almost three times the odds of being depressed and anxious than those who were not exposed.
These behavior problems appeared more severe among children who had also experienced another traumatic event. Compared with children who were not exposed to high-intensity WTC events or to other trauma, those who were exposed to both had 21 times the odds of having emotional problems or being anxious or depressed and 16 times the odds of having attention problems. Those who were exposed only to high-intensity WTC events and not to other traumatic events were not significantly more likely to have behavioral problems than those with only less intense exposure to the attacks.
The findings are consistent with an allostatic load theory of stress, which holds that accumulated exposure to difficult events increases the risk of psychological effects, the authors note. "Physicians seeking to assess the impact of terrorism and disaster on very young children should assess for disaster-related exposure and for other trauma," they write. "More vigorous outreach to trauma-exposed preschool children should become a post-disaster public health policy."
