The issue of whether mild head injuries (HIs) in children cause behavior pr
oblems and poor scholastic performance is controversial. This study include
d 119 children (range = 8-16 years old) with HI, 114 with other injuries, a
nd 106 with no injury (NI). Behavioral functioning was assessed with the Ch
ild Behavior Checklist; academic functioning, with school grades and standa
rdized testing. Higher T scores were found for both injury groups versus NI
participants on preinjury behavioral status. All 3 groups' behavioral scor
es decreased relative to baseline at 1 year. HI and NI groups did not diffe
r in school grades or achievement testing either pre- or postinjury. These
results are consistent with the conclusion that head injury of the mildest
type does not increase the probability of new overt behavioral or academic
problems.
