Driving Anger Scale, French adaptation: further evidence of reliability and validity.

This study was conducted to provide further evidence of reliability and validity for the Driving Anger Scale, French version. A sample of 202 drivers, ages 18-25 years, completed the scale and the general Trait Anger scale from NEO Personality Inventory-Revised. Factor analysis indicated five factors similar to those found in the original U.S. version. The 'Traffic Obstructions' and 'Slow Driving' factors have been slightly modified, and 'Discourtesy' was abandoned. Positive correlations were observed between scores on the Trait-Anger scale from the NEO Personality Inventory-Revised and the Driving Anger Scale (r = .41) and with its factors (from .24 to .38), except for 'Illegal Driving'. The internal consistency of the Driving Anger Scale was acceptable for the total score (alpha = .82) and for factors ranged from .74 to .80. This French version can be preliminarily recommended for the assessment of driving anger in France among young drivers.
