Aim: The aim of this study was to develop and provide initial validation data for a self-awareness of on-road driving ability measure for individuals with brain injury. Method: Thirty-nine individuals with Traumatic Brain Injury completed an on-road driving assessment, the Self-Regulation Skills Interview (SRSI) and the newly developed Brain Injury Driving Self-Awareness Measure (BIDSAM). Results: BIDSAM self, clinician and discrepancy scales demonstrated high levels of internal consistency (α = 0.83–0.92). Criterion-related validity was established by demonstrating significantly higher correlations between clinician ratings and on-road performances, rs = 0.82, P < 0.01, compared to self-ratings, rs = 0.45, P < 0.05. Discrepancy scores were significantly correlated with the SRSI emergent, rs = 0.52, P < 0.01, and anticipatory awareness scores, rs = 0.37, P < 0.05, indicative of convergent validity. Conclusions: These results provide initial support for the BIDSAM as a reliable and valid measure of self-awareness of on-road driving ability following TBI.
