Psychometric Properties of the Driving Behavior Survey among Iranian Drivers

Objective: There are not enough good instruments for assessing driving behavior in Iran. This study aimed to investigate factor structure, convergent and divergent validity, and reliability of driving behavior survey (DBS). Methods: The study method is descriptive and survey. Participants comprised ۱۴۷ Sample selected by convenient method. Iranian drivers who completed DBS, Manchester driver behavior questionnaire, trait anxiety scale, and trait anger scale. Results: findings showed that ۳ factors of DBS could explain ۳۹% of total variance. Anxietybased performance deficits, exaggerated safety and caution behaviors, and hostility/aggressive behaviors were ۳ factors of DBS. There were convergent correlations between DBS subscales and common driving mistakes and traffic rules violations. Cronbach’s alpha was estimated ۰.۷۷, ۰.۶۵ and ۰.۷۰ for subscales. Conclusion: Driving behavior survey has convincing psychometrical features. It could be used in general population and clinical settings for investigating anxious drivers.
