Abstract

Objectives: The purpose of the current research was to investigate the relation of varieties of personality aggression types according to Karen Horney’s theory (Malevolence, Power, and Strength) with negative (errors and violations) and positive driving behaviors and frequency of accidents. Method: For this purpose, 263 volunteer drivers with generalized driving license (base two) were selected. The subjects completed Negative and Positive Driving Behavior Questionnaire (NPDBQ) and Horney-Coolidge Tridimensional Inventory (HCTI). They were also asked to indicate the number of accidents in which they had been faulty in the last 5 years. Results: Results of multiple regression analysis and correlation matrix showed that all three kinds of aggressions had positive and significant correlation with violations and errors and negative and significant correlation with positive driving behaviors (p<0.05). There was a negative and significant correlation between aggressions and driving behaviors. There was no significant correlation between the aggressions and the frequency of accidents. However, gender had a significant relation with frequency of accidents. Conclusion: Different types of aggressions, regarding gender, have important role in prediction of driving behaviors and accidents.
