Abstract
The purpose of the current study was to examine psychometric properties of the Driver Expression Inventory (DAX) in Argentina. A sample of 378 drivers (males=50.3%) aged 18 to 77 years old from the general population of Cordoba, Argentina, participated in the study. Unrestricted factor analysis yielded five factors consistent with the original scale. Internal consistency were satisfactory for all DAX subscales (α=.78 -.85). Correlations between DAX and measures of driving anger and drivers' behavior provided concurrent validity. Finally, hierarchical regression analyses showed additional and significant contribution of the DAX in predicting driving-related behaviors beyond demographic variables (i.e. age and gender) and driving anger, supporting for incremental validity. Overall, results support the validity and reliability of the DAX in Argentina, although we note that further studies are needed in order to evaluate additional psychometric properties.
