Self-awareness predicts fitness to drive among adults referred to occupational therapy evaluation.

PMID 36466937WHAT IT FOUND
In older adults referred for driving evaluation, self-awareness predicted fitness to drive better than cognitive or motor speed.
Those deemed unfit significantly overestimated their driving ability, while those deemed fit rated themselves accurately. Assessing this gap helps identify drivers who do not recognize their own errors.
Key findings
01Driving self-awareness was the only significant predictor of fitness to drive in the regression analysis, whereas cognitive and motor processing speed were not.
02Participants classified as unfit to drive significantly overestimated their driving abilities compared to instructor ratings, while those classified as fit had accurate or close-to-accurate self-awareness.
03There were no significant differences between fit and unfit groups in how they self-rated their driving performance before or after the on-road test.

What it does not show
The sample was small (39 participants) and heterogeneous, including various diagnoses and reasons for referral, which limits generalizability to specific conditions like dementia or stroke. Six potential participants were excluded due to missing data, reducing the analyzed sample from 45. The study relied on a single on-road experience, which may not capture variability in driving performance or self-awareness over time. The final fitness decision was made solely by the occupational therapist, introducing potential subjective bias in group allocation.
Declared interests
The text does not explicitly state funding sources or conflicts of interest, but notes the study was approved by the hospital's Helsinki Committee and based on data from a practicing clinic.
The easy way to misread this
Do not assume that fast cognitive or motor processing speed guarantees safe driving. In this study, these measures did not predict fitness to drive once self-awareness was considered. A patient can have normal reaction times but still be unsafe if they cannot recognize their own driving errors.
