The Chinese version of driver behaviors questionnaire (DBQ) :reliability and validity

Objective To test the rehability and validity of the ear driver behavior questionnaire (DBQ).Methods One hundred twenty ear drivers in Chengdu were investigated randomly by DBQ,and then factor analy-sis,reliability and validity tests were performed by SPSS15.0.Results ①Three factors were extracted,namely speeding & violation behavior,error and lapses,which explained 42.027% of the total variance. ②The three fac-tors' Cronbaeh α were 0.834,0.765 and 0.644 respectively,and they were significantly correlated with the total questionnaire(r=0.859 ,0.824,0.676,P<0.01).③Compared with safe driver,unsafe driver scored higher on total driving behaviors and speeding &violation behavior(P<0.05,P<0.01).Conclusion DBQ has good reliability and validity,and is an effective instrument to test drivers' behaviors.
