Despite the potential dangers associated with premature
return to driving after stroke, very little research has examined the
relationship between impaired self-awareness (ISA) and driving. This study
examined self-awareness of driving simulator and neuropsychological performance
among stroke patients, comparing them with healthy control participants. METHODS:
Thirty stroke survivors and 30 controls each were asked for prediction and
postdiction ratings of their performance on various driving simulator and
neuropsychological tasks. Self-estimates versus actual performance discrepancy
scores were calculated for various simulator and neuropsychological measures by
converting scores to a shared metric. RESULTS: Across all measures, the stroke
survivors greatly overestimated their performance in comparison with the accuracy
of self-evaluations among the controls, thus suggesting ISA. This pattern of
overestimating was observed on both novel (neuropsychological) and familiar
(driving) tasks. However, there was some evidence to suggest that stroke
survivors can benefit from feedback, as seen by increased accuracy in postdiction
versus prediction self-evaluation scores. Both stroke survivors and controls also
showed a greater shift toward accurate self-estimation on postdiction of driving
performance than on postdiction of neuropsychological test performance.
CONCLUSION: Although the temporal stability of the shift in awareness is not
known, these results support the use of driving simulators as a useful and safe
method of assessing and potentially improving stroke survivors' ISA.
