Examined posttraumatic stress (PTS) symptoms in children following pediatri
c traumatic brain injury (TBI). Children (ages 6-12) with TBI (n = 81) and
orthopedic injury (OI; n = 59) were assessed 6 and 12 months postinjury. Pa
rents of children with severe TBI reported higher levels of child PTS sympt
oms than did parents of children with moderate TBI or OI at the 6- and 12-m
onth follow-ups. Group differences in child-reported PTS symptoms emerged a
t the 12-month follow-up with higher symptom levels reported by children wi
th severe TBI than by those with moderate TBI or OI. At both follow-ups, ra
tes of clinically significant symptom levels were higher in the severe TBI
group than in the moderate TBI or OI groups. The group differences in paren
t and child reports were significant even after taking ethnicity, social di
sadvantage, and age at injury into account. Parent and child reports of chi
ld PTS symptoms were related to family socioeconomic status. Implications f
or clinical intervention with children and families following pediatric TBI
are discussed.
