Abstract/Description:
Over the past decade, aggressive driving behavior has become a topic of concern among the public, media, and researchers in the psychological community. Aggressive driving is a problematic pattern of social behavior that is not only a leading cause to motor vehicle accidents, but a serious threat to public safety. One instrument that has been developed to assess aggressive driving behavior is the Aggressive Driving Behavior Questionnaire (ADBQ). The ADBQ is a 20-item paper and pencil questionnaire intended to measure a driver's likelihood for engaging in aggressive driving behavior. The ADBQ was developed using a factor-analytic approach that combined five previously developed aggressive driving behavior scales (Brill, Mouloua & Shirkey, 2007). Of the 81 items of the five combined scales, nineteen latent variables were extracted and accounted for 67.4% of the explained variance for the observed responses. The final 20th item was developed by splitting one of the latent variables. A previous study, conducted at Old Dominion University (N = 230) and Michigan Technological University (N = 265), examined the ADBQ's factor structure and internal consistency, and found relatively high internal consistency (Cronbach's alpha = .77) and the identification of six factors using a principal axis factor analysis (Brill & Mouloua, 2011). The ADBQ was also tested in a controlled laboratory environment and found significant evidence that suggest the ADBQ is a valid predictor of aggressive driving behavior in a simulated environment (Brill, Mouloua & Shirkey 2009). The purpose of the present study was to further investigate the psychometric properties of the ADBQ. Based on a sample of 285 undergraduates (170 women and 115 men) from the University of Central Florida, the study examined the internal consistency, predictive and construct validity, and factor structure of the new questionnaire. A principal axis factor analysis with promax rotation yielded four factors, or joint variations between the 20 items, that were inter-correlated with eigenvalues greater than 1. The ADBQ was also found to have high internal consistency (Cronbach's alpha = .86). The four factors were used to form four subscales of aggressive driving behavior that included anger/aggression, speeding/minor infractions, overt expression, and judgment of other drivers. The four subscales were found to correlate with self-reported biographical and driver history data, as well as, gender differences across scales. Additional analyses were conducted using data from the present sample from the University of Central Florida (N = 285) and the data from the previous study from Old Dominion University (N = 230) and Michigan Technological University (N = 265) for a combined sample of 780 undergraduate students. The findings in this present study provided additional support for the consistency, predictive validity, and factor structure of the ADBQ instrument. The Aggressive Driving Behavior Questionnaire proves to be a valuable measure in predicting the likelihood of a person engaging in aggressive driving behavior. The implications for driving behavior assessment, training, and instrument development are also discussed.
