Objective: We aimed to evaluate cognitive performance, biomarkers and self-reported sensory function as correlates of self-reported driving behaviour and confidence. Methods: A volunteer sample of 153 drivers aged between 60 and 90 were assessed on biomarkers (vision, hearing, (vibration sense, grip strength and FEV1), and cognitive performance. A subsample of 121 also completed a questionnaire on driving behaviour, driving confidence and self-reported sensory function. Structural equation modelling techniques were used to evaluate the relative importance of subjective and performance-based variables. Results: Driving behaviour and confidence were associated with cognitive performance, biomarkers, chronological age and one question on self-rated hearing difficulty. Structural equation modelling showed that biomarkers were most important in predicting self-reported driving behaviour. Conclusion: These results suggest that individuals self-monitor according to their physiological well-being and report their driving behaviour accordingly.Keywords: adult; age; aged; article; cognition; controlled study; driving ability; female; forced expiratory volume; grip strength; hearing; hearing impairment; human; prediction; priority journal; questionnaire; self report; sensorimotor function; statistical mode Cognition; Driving; Functional age; Hearing; Physiological aging; Vision200310.1159/0000691772015-12-11
