BACKGROUND: Video feedback interventions have been found to improve
self-awareness and occupational performance to a greater extent than other
feedback interventions after traumatic brain injury (TBI). However, it is unclear
whether the effects of video feedback are maintained over time.
OBJECTIVE: To evaluate the maintenance of gains in self-awareness achieved with a
video feedback intervention in people with TBI.
METHODS: Participants were 32 participants with TBI and impaired self-awareness
who had completed a randomized controlled trial with three feedback conditions
(video plus verbal, verbal and experiential). Eight to ten weeks after the final
feedback intervention session, a follow-up assessment was conducted. The primary
outcome was maintenance of gains in online awareness measured by the number of
errors made during a meal preparation task. Group outcomes were compared using an
unstructured linear mixed regression model.
RESULTS: The video plus verbal feedback group continued to demonstrate
significantly greater gains in online awareness compared to the verbal feedback
group (mean difference 20.6, 95% CI 8.8 to 32.3) and the experiential feedback
group (mean difference 14.4, 95% CI 3.1 to 25.6). There was no significant impact
of the interventions on participants' emotional status at the 8 to 10 week
CONCLUSIONS: A combination of video plus verbal feedback is an effective
technique for achieving maintained gains in self-awareness in people with TBI.
