Objectives: To examine emotional and behavioral adjustment and recovery ove
r 1 year after traumatic brain injury (TBI), and to determine whether the d
ifficulties, if present, are due to neurologic insult.
Design: Longitudinal evaluation of adjustment from 1 month to 1 year after
injury.
Setting: Level I trauma center at a university hospital.
Patients: One hundred fifty-seven consecutively hospitalized adults with TB
I and 125 trauma controls with other system injuries evaluated at 1 and 12
months after injury.
Main Outcome Measures: Katz Adjustment Scale (KAS).
Results: The TBI group at 1 year follow-up demonstrated significant emotion
al and behavioral maladjustment, but such difficulties did not appear to be
mediated by the brain injury, since the KAS scores for the TBI and trauma
control groups were not significantly different. Those with moderate TBI re
ported greater difficulties than those with mild or severe injuries. Change
s in adjustment over 1 year were common for both groups. Within the TBI gro
up there was differential recovery: improvement in cognitive clarity, dysph
oric mood, and emotional stability, but increased difficulties with anger m
anagement, antisocial behaviors, and self-monitoring,
Conclusions: These results raise questions about commonly held beliefs that
those with mild TBI report greater distress, and clarify some misconceptio
ns regarding change in emotional and behavioral functioning over time. (C)
