Management of impaired self-awareness in persons with traumatic brain injury.

AIM

To develop and evaluate a systematic intervention programme for the management of impaired self-awareness (ISD) in people with traumatic brain injury.

METHODS

This study adopted a pre-test-post-test control group design. Twenty-one patients with traumatic brain injury were randomly assigned to an experimental group and a control group according to their admission sequence. The groups joined a newly developed Awareness Intervention Programme (AIP) and a conventional rehabilitation programme respectively for 4 weeks. Pre- and post-intervention outcome measures taken from the two groups were compared. Wilcoxon Signed-Ranks Tests were conducted to compare the within-group changes of the outcome measures of the Self-Awareness of Deficits Interview (SADI), the Functional Independence Measure (FIM) and the Lawton Instrumental Activities of Daily Living Score (Lawton IADL) in the control and experimental groups. Mann Whitney U-tests were conducted to compare the across-group differences of improvements of outcome measures between the participants in the two groups.

RESULTS

After AIP training, the participants in the experimental group demonstrated significant improvement in their level of awareness as compared to the control group. However, the functional outcomes of the participants in experimental group did not show significant differences.

CONCLUSION

The AIP can promote improvement in the level of self-awareness of people with traumatic brain injury. This new programme can be further developed to extend a better carryover treatment effect to functional improvement in daily activities.
