Highlights: [•] CFA supported the unidimensional nature of both the DAS and PADS. [•] The PADS was a significant predictor of violations. [•] The DAS was a significant predictor of near-misses. [•] Neither of the scales were significant predictors of crash-involvement. [ABSTRACT FROM AUTHOR]

Abstract: The present study used a university sample to assess the test–retest reliability and validity of the Australian Propensity for Angry Driving Scale (Aus-PADS). The scale has stability over time, and convergent validity was established, as Aus-PADS scores correlated significantly with established anger and impulsivity measures. Discriminant validity was also established, as Aus-PADS scores did not correlate with Venturesomeness scores. The Aus-PADS has demonstrated criterion validity, as scores were correlated with behavioural measures, such as yelling at other drivers, gesturing at other drivers, and feeling angry but not doing anything. Aus-PADS scores reliably predicted the frequency of these behaviours over and above other study variables. No significant relationship between aggressive driving and crash involvement was observed. It was concluded that the Aus-PADS is a reliable and valid tool appropriate for use in Australian research, and that the potential relationship between aggressive driving and crash involvement warrants further investigation with a more representative (and diverse) driver sample.

Abstract: Road rage is a topic that receives consistent attention in both the road safety literature and media. Before Australian research can address the underlying factors associated with road rage, there is a need for a valid instrument appropriate for use in this context. The present program of research consisted of two studies. Study 1 used a university sample to adjust the scoring technique and response options of a 19-item American measure of the propensity for angry driving with acceptable reliability and validity. In Study 2, Factor Analysis confirmed a one-factor solution and resulted in a 15-item scale, the Australian Propensity for Angry Driving Scale (Aus-PADS), with a coefficient alpha of .82 (N =433). The Aus-PADS may be used in future research to broaden the Australian road rage literature and to improve our understanding of the underlying processes associated with road rage in order to prevent the problem. Future research should also confirm the factor structure and generate normative data with a more representative sample. [Copyright &y& Elsevier]
