The expression of anger amongst Turkish taxi drivers

The present study tested the four factor structure of the DAX on a sample of Turkish taxi drivers and the relationship these factors had with a number of other variables. Confirmatory Factor Analysis found that the data broadly fit the four factor solution of the DAX. These factors included three aggressive expressions: Verbal Aggressive Expression; Personal Physical Aggressive Expression; Use of a Vehicle to Express anger, and one Adaptive/Constructive factor. Driving experience was negatively related to the three types of aggressive expression. The Total Aggressive Expression was positively related to annual mileage and preferred driving speed, but negatively related to age and experience. The present research also found that the three aggressive types of anger expression were significantly related to potentially crash related conditions, such as losing control of the vehicle, loss of concentration and near-misses. However, none of the DAX factors was significantly related to either minor or major crashes.
