Driving is not means just applying technical skills to control the vehicle, but rather reflects the driver's classification of character. One of including variables related to driving is aggression. And causes a lot of dangers in driving. Based on our surveys through the world, questionnaire is the practical tool to assess driving behavior. The aim of this study is to assess the validity and reliability of DVQ's Persian version. Materials and Methods: The 15-item DVQ was translated to Persian according to retranslation method. In the revised version, 3 new items were added and then completed by 400 staffs of North Khorasan University of Medical Sciences. Finally, we employed retranslation method and Cronbach's alpha coefficient to validity assessment. Results: The mean age of the subjects was 35.88 years old. 301 Participants were male and 99 were female. We recognized in PCA Test 2 subscales which showed variance of 36.5% that their Cronbach's Alpha was between 0.68 to 0.78.ICC Test for 2 subscales and total questionnaire were from 0.75 to 0.87. There were significant correlation among factors such as DVQ score, sex and age. Conclusion: The results indicated that the 18-item Persian version of DVQ is a suitable criterion to recognize driver revenge-seeking behavior.
