The Dula Dangerous Driving Index (DDDI) is a cross-cultural validated instrument that measures simultaneously various manifestations of behaviours, cognitions, and affects associated with dangerous driving. The aims of the study were to translate the DDDI into French and then to verify the validity and reliability of the French version of the scale by means of observed behaviours on a driving simulator, and of self-reported measures of driving behaviours, personality and sociodemographic characteristics. A first sample of 395 drivers completed self-reported questionnaires and a second sample of 75 male drivers also completed tasks on a driving simulator. A confirmatory factorial analysis supported the internal validity of the scale. Findings also show that the French version of the DDDI yields good internal consistency, concomitant and convergent validity for each subscale (risky driving, negative cognitive/emotional driving and aggressive driving) and total score. The scale was useful to differentiate sociodemographic and psychological profiles associated with each subscale.
杜拉危险驾驶指数（DDDI）是一种跨文化验证的工具，可同时测量与危险驾驶相关的行为、认知和情感的各种表现。本研究的目的是将 DDDI 翻译成法语，然后通过驾驶模拟器上的观察行为和自我报告的驾驶行为、个性和社会人口特征测量，验证该量表的有效性和信度。第一组 395 名驾驶员完成了自我报告问卷，第二组 75 名男性驾驶员也完成了驾驶模拟器上的任务。验证性因素分析支持了该量表的内部有效性。研究结果还表明，DDDI 的法译本对于每个子量表（冒险驾驶、消极认知/情绪驾驶和攻击性驾驶）和总分都具有良好的内部一致性、伴随有效性和收敛有效性。该量表可用于区分与每个子量表相关的社会人口学和心理特征。
