Aggressive behaviour on the roads is reported to be on the increase. This study administered Driving Anger Scale (Deffenbacher,JL, Oetting,ER & Lynch,RS (1994). Development of a driving anger scale. Psychological Reports, 74, 83-91), the Driver Behaviour Questionnaire, and the Driving Skill Inventory to a sample of 20 British drivers. Factor analysis of the Driving Anger Scale items yielded three factors measuring anger generated by the reckless driving, direct hostility and impeded progress by others - contrary to the six subscales found with the original US sample. Younger drivers and low mileage drivers were more likely to exhibit all three types of driving anger, but no differences between male and female drivers were found. In addition, a driver's safety orientation predicted (negatively) anger evoked by impeded progress and direct hostility whereas self-assessed perceptual-motor skills were positively related to anger generated by impeded progress. Both Highway Code and aggressive violations were significantly related to the anger factors, and, using the procedure by Baron and Kenny (Baron,RM & Kenny,DA (1986). The moderator-mediator variable distinction in social psychological research: conceptual, strategic, and statistical considerations. Journal of Personality and Social sychology, 51, 1173-1182). the prediction of violating behaviour (Driver Behaviour Questionnaire) by reported anger was shown to be mediated by the self-assessed safety skill scale but not the perceptual-motor skill scale (Driver Skill Inventory), and moderated by neither. Implications for driver education countermeausres are noted. (Author/publisher).
