The Associated Factors And Psychological Intervention Of Driving Anger And Aggression For Plateau Military Truck Drivers

Traffic accident has been considered as the first threat to the safety of the society. Researches indicated that car accidents caused by drivers account for84～90%of all road traffic accidents, and the driving anger and driving aggression of drivers are the key factors which trigger the car accidents. Plateau military drivers are high-risk population, usually bear a heavy routine transportation missions, floods or earthquake rescue and other non-combat military tough tasks. On the battlefield, logistic support is the important for war, in which transportation is most key factor, so it is easy to be the attack point by enemy. On one hand, the hard environments such as bad climate, hypoxic condition, mud-rock problem, the dangers of the road, and high-risk, high-intensity driving tasks make the driving soldiers easier to be anger and seriously affect transportation capacity. On the other hand, the destructive damage of the weapon and psychological fighting in future war is bound to bring the driving soldiers greater mental stress, which will make the driving anger easier to be triggered and the defense force of the war to be weakened. Based on the need of the army, the present research is to study the status, related factors and the psychological intervention of driving anger and driving aggression for plateau military drivers. The purposes of this study are to provide some evidences to the selection and training of plateau military drivers, then to improve the defense force and the capabilities of stress coping of the automotive force.There are three topics in this project. Firstly, a total of441randomly selected plateau military truck drivers were investigated with Driving Anger Scale (DAS) and Driving Anger Expression Inventory (DAX), and the status and demographic of driving anger and driving aggression have been analyzed. Secondly, a total of229plateau military truck drivers were selected, and their psychological factors of driving anger and driving aggression have been estimated as well. According to the data, the Multiple Regression Equations of psychological factors for both driving anger and driving aggression were established. Thirdly, based on the related factors, a total of60plateau military truck drivers with high score of both driving anger and driving aggression were selected, and to be assigned into cognitive-behavioral training group, relaxation group and control group respectively. In the assessment of the results, biological, psychological and behavior indexes were applied.The follows are the main results:1. The higher mean score items of driving anger focus on subscales of "hostile behavior","progress impeded". The old drivers with more experiences report lower score of driving anger and driving aggression.2. The multiple regression equation of driving anger is Y=23.816+0.287state anxiety+0.253trait anger-0.242agreeableness; The multiple regression equation of driving aggression is Y=48.418+0.462trait anger-0.250agreeableness+0.243catastrophizing+0.370trait anxiety+0.367state anxiety+0.173driving anger.3. In both cognitive-behavioral training and relaxation training groups, the scores of state anxiety and depression are significantly decreased on the next day and3months after treatment; With the stressors on the next day after treatment, the pre-post difference of heart rate in cognitive-behavioral group is minimum, the pre-post difference of the adrenocorticotropic hormone and cortisol level in saliva in relaxation group is significantly lower than the other2groups; In cognitive-behavioral group, the score of "adaptive expression" is significantly increased, and the score of "verbally aggressive expression" is significantly decreased in three months after treatment. While in relaxation training group, there were no differences with either the score of "adaptive expression" or "verbally aggressive expression".The main conclusions are:1. The main environment factors triggering driving anger and driving aggression of plateau military drivers are "hostile behavior" and "progress impeded". The main demographic factors of driving anger and driving aggression of plateau military drivers are age and driving experience.2. Trait anger and agreeableness are the common indicators to predict both driving anger and driving aggression for the plateau military drivers. The level of driving anger of the plateau military drivers may predict driving aggression on certain degree, but did not trigger driving aggression certainly.3. Both cognitive-behavior and relaxation group training can relieve the physiological arousal, anxiety and depression. Cognitive-behavior training can reduce driving aggression, and increase the "adaptive expression" when confronting driving anger. Relaxation training has no effect on driving behavior.4. Personality Traits, cognitive emotion regulation strategies and emotional traits should be the selective factors of plateau military drivers. Psychological training should be necessary for both recruit training and conventional training to plateau military drivers.Based on the results of this study and previous research results, we established three theoretical model of driving anger and driving aggression to plateau military drivers:the interaction effect model of personal personality traits-emotion-cognition for the occurrence of driving anger and driving aggression, the appraisal and re-appraisal model of driving anger-driving aggression, the cognitive-behavior training model of driving anger and driving aggression.The participants of this study are plateau military drivers, the results of this study can be applied to the automotive force. However, since the hard environments and high risk tasks of plateau military drivers are different from the non-military professional drivers, besides, the plateau military drivers have received special military training, the results of this study could not be applied to the non-military professional drivers in the culture of the society.
