The healthy and PTSD groups did not significantly differ in sex distribution, age, Tanner stage, IQ, or handedness. The PTSD Reaction Index was determined by the greater of youth and caregiver scores for each item. CAPS–CA scores were not collected for the first four PTSD participants. The MFQ and SCARED represent the average of youth and caregiver reports. Numbers in parentheses with ‘±' represent SEM.
