Developing of an English Version of the Aggressive Driving Behavior Test (AVIS). Improving the Construct Validity of Aggressive Driving

The research investigated the psychometric properties and the discriminant validity of the English version of the Questionnaire for the Assessment of Aggressive Driving Behavior (AVIS). Study 1 assessed the psychometric properties of the instrument. Internal consistency ranged from 0.77 to 0.92. Exploratory factor analysis did not support the original five factor structure, Instrumental Aggression and Acting Out being unified in a single factor. Following the confirmatory factor analysis a version with 26 items and 3 factors was obtained. Inter-scale correlations showed that the dimensions of the AVIS are inter-correlated. Study 2 verified the discriminant validity of the English version of the AVIS by testing the relationships between the AVIS dimensions and the DAX (Driving Anger Expression Inventory) dimensions. The results showed good discriminant validity, the dimensions of the two instruments being uncorrelated. In conclusion, the findings contribute to the development of the driving aggression construct by adding new dimensions to it.
