本研究的目的是将杜拉危险驾驶指数(DDDI)翻译成中文，并验证其信度和效度。共有246名司机完成了DDDI中文版和司机行为问卷(DBQ)。还测量了特定的社会人口学变量和交通违法行为。验证性因素分析证实了DDDI的内部结构，中国支持四因素模型。收敛效度和效标效度检验表明，中国的DDDI是有效的。其收敛效度与DBQ呈正相关，与自报事故卷入和交通违法的关系检验其效标效度。最后，不同人口统计群体之间的得分比较显示出显著的差异，从而将年龄和驾驶年限与危险驾驶联系在一起。
The aim of this study was to translate the Dula Dangerous Driving Index (DDDI) into Chinese and to verify its reliability and validity. A total of 246 drivers completed the Chinese version of the DDDI and the Driver Behavior Questionnaire (DBQ). Specific sociodemographic variables and traffic violations were also measured. A confirmatory factor analysis confirmed the internal structure of the DDDI, and the four-factor model was supported in China. Measures of convergent and criterion validity demonstrated that the Chinese DDDI was valid. Its convergent validity was supported by its positive relationship with the DBQ, and its criterion validity was tested using its relationship with self-reported accident involvement and traffic violations. Finally, score comparisons between different demographic groups revealed significant differences, thereby linking age and driving years to dangerous driving.
