An 18-month longitudinal study of posttraumatic disorders in children who were taken hostage in their school.
OBJECTIVE
The objective of our investigation was to study the course of direct and indirect posttraumatic disorders over 18 months in children after they were taken hostage in their school.


METHODS
Twenty-six young hostages were evaluated by using standardized clinical interviews and self-administered questionnaires (State and Trait Anxiety Inventory for Children [STAIC]and Revised Impact of Event Scale [IES]) 2, 4, 7, and 18 months after the event. They were compared with 21 children from the same school who were not taken hostage (indirect exposure).


RESULTS
Symptoms of acute stress were observed in 25 (96%) of the children who were directly involved in the traumatic event. After 2 months, 18 children had developed disorders according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, including 7 cases of full posttraumatic stress disorder (PTSD), 11 cases of subclinical PTSD, 3 cases of separation anxiety, 1 case of specific phobia, and 2 cases of major depressive disorder. Anxiety scores (STAIC) decreased between 2 and 4 months and then stabilized, whereas symptoms of avoidance (IES-avoidance) decreased gradually throughout the follow-up period, and symptoms of repetition (IES-intrusion) decreased less markedly. Children who were indirectly exposed to the trauma also manifested protracted posttraumatic symptomatology (two full cases of PTSD and six cases of subclinical PTSD), but their IES-intrusion scores were significantly lower at 7 months than those of children who were directly exposed, and the severity of their symptoms diminished over time. Girls tended to show a higher level of anxiety and more features of intrusion than boys. Psychological debriefing did not prevent occurrence of the disorders, but children who were not debriefed had the worst outcomes.


CONCLUSIONS
Even after a short event and even if they are not directly exposed, children under the age of 9 years can develop high rates of posttraumatic disorders that follow a protracted course despite early intervention and careful monitoring.
