Self-report questionnaire measures of driving behaviour and attitudes are used to study aspects of driving, driver stress and coping strategies, in order, for example, to identify possible predictors of accident risk and driving style. Participants typically complete such questionnaires by reflecting on their recent driving history. In this study the relationship between questionnaire measures and driving style was investigated by comparing questionnaire scores with actual driving in a driving simulator. Participants completed four experimental drives on simulated U.K. rural roads, in both relaxed and time-pressured situations. A wide range of aspects of their driving behaviour were recorded, including mean and maximum speeds, mean RPM, maximum brake position, standard deviation of lateral position and time spent out of lane. Participants also completed the Driver Stress Index (DSI), Driver Coping Questionnaire (DCQ), Driver Behaviour Questionnaire (DBQ), and the Positive Driver Behavior Scale (PDBS). Correlations were found between several measures associated with a faster driving style in the simulator, and the Aggression and Thrill Seeking dimensions of the DSI, the Confrontive Coping dimension of the DCQ, and the Violations dimension of the DBQ. The results suggest that self-report questionnaire measures of driving behaviour and attitudes may be useful predictors of actual driving style, and they contribute to the external validity of driving simulation.
