Objective: To describe the long-term outcome 5 years after injury of y
oung adults who were 15 to 19 years old at the time of their head inju
ries. Design: A retrospective cohort. The health records of 62 consecu
tive eligible subjects were abstracted for baseline sociodemographic,
health, and injury variables. A telephone interview was administered t
o assess quality of life, impairment, disability, and handicap. Settin
g: Canada's largest trauma center, Sunnybrook Health Science Centre, T
oronto, Canada. Subjects: Of the 58 subjects (94%) who were traced at
follow-up, 51 agreed to participate. Main Outcome Measures: The Medica
l Outcomes Study SF-36, Head Injury Symptom Checklist, selected disabi
lity measures, Community Integration Questionnaire. Results: Of the 8
summary items of the Medical Outcomes Study SF-36, subjects scored low
est on mental health. There were no significant differences between mi
ld and more severely injured groups in all quality of life measures. S
ubjects classified with mild head injury overall reported more symptom
s from the Head Injury Symptom Checklist. Subjects with more severe in
juries had lower community integration scores (p < .05). Conclusions:
Overall, mental health is an important area of concern at follow-up fo
r all subjects. Adolescents with apparent mild head injury can have di
sabling symptoms many years after injury. (C) 1998 by the American Con
