Abstract

The present study investigated the factor structures of the 14-item version of the DAS (Driving Anger Scale) and the Propensity for Angry Driving Scale (PADS) using a sample of New Zealand drivers drawn from the general population. The two scales were also investigated with regards to their relationships with general trait anger, risky driving behaviour, along with crash involvement and a variety of crash-related conditions. Confirmatory Factor Analysis supported both scales as unidimensional, although the PADS was reduced from a 19-item to an 18-item scale. Both the PADS and DAS were significantly related to trait anger, risky driving behaviour and near-misses. However, once the influence of the demographic variables and trait anger had been partialled out, the addition of the PADS and DAS made a significant contribution to predicting violations, but it was only the PADS which was significant. In contrast, after the demographic variables and trait anger had been partialled out, the addition of the DAS and PADS again made a significant contribution to the prediction of near-misses, but this time it was only the DAS which made a significant contribution. The present study clearly shows that both scales are robust measures, measuring similar, but slightly different aspects of driving anger.
