To assess the amount of stress exposure and reactions among children following a war situation, two comparative groups of non-displaced (N = 64) and displaced children (N = 70) from Croatia were administered a modified version of the War Trauma Questionnaire as well as the Impact of Event Scale (IES). The results showed that a majority of the children had been exposed to armed combat, with displaced children significantly more exposed to destruction of home and school as well as to acts of violence, and loss of family members, than the non-displaced children. Regarding the IES scores, displaced children had significantly higher scores for the total score and for the intrusion and avoidance subscales. For girls the total score and intrusion score were significantly higher than for boys. Different exposure factors were significantly related to the IES scores, especially for the intrusion subscale of the IES.
