Samenvatting
The present study further validated the Driving Vengeance Questionnaire (DVQ), assessing the frequency of past acts of severe and dangerous violent driving behaviours, as well as milder driver aggression measured in actual driving conditions. DVQ scores were predicted by driver violence, where vengeful drivers reported greater acts of past violence. DVQ scores were also predicted by mild driver aggression measured in high traffic congestion, such that vengeful drivers were more likely to exhibit mild aggression in high congestion conditions. Finally, the DVQ demonstrated high internal consistency (alpha=0.8 1), demonstrating the DVQ to be a reliable and valid measure of driving vengeance. (A)
