BACKGROUND: Feedback is used in rehabilitation to improve self-awareness in
people with traumatic brain injury (TBI), but there have been no comparisons of
the different methods of providing feedback.
OBJECTIVE: To compare the effect of different methods of feedback on impaired
self-awareness after TBI.
METHOD: This was a randomized, assessor-blinded trial with concealed allocation.
A total of 54 participants with TBI and impaired self-awareness (85% male) were
recruited from inpatient and community rehabilitation settings. Participants
performed a meal preparation task on 4 occasions and were randomly assigned to 1
of 3 feedback intervention groups: video plus verbal feedback, verbal feedback,
or experiential feedback. The primary outcome was improvement in online awareness
measured by the number of errors made during task completion. Secondary outcomes
included level of intellectual awareness, self-perception of rehabilitation, and
emotional status.
RESULTS: Receiving video plus verbal feedback reduced the number of errors more
than verbal feedback alone (mean difference = 19.7 errors; 95% confidence
interval [CI] = 9.2-30.1) and experiential feedback alone (mean difference = 12.4
errors; 95% CI = 1.8-23.0).
CONCLUSION: The results suggest that the video plus verbal feedback approach used
in this study was effective in improving self-awareness in people with TBI. The
results also provide evidence that improvement in self-awareness was not
accompanied by deterioration in emotional status.
