Groups were based on the Anxiety Disorders Interview Schedule for DSM-IV: Child Version (ADIS-C). Independent-sample t-test was conducted to examine differences between children with and without PTSD. All p-values were <0.05 except for items 5 and 7. CRIES = Children's Revised Impact of Event Scale; PTSD = posttraumatic stress disorder.
