职业驾驶员驾驶愤怒量表信度和效度分析

Reliability and validity of Driving Anger Scale in professional drivers in China

目的 研究中文版驾驶愤怒量表（Driving Anger Scale,DAS）在职业驾驶员群体中使用的信度和效度.方法 选取宜兴市出租车、公交车、货车、公车以及校车等481名职业驾驶员进行现场调查,并通过Cronbach＇sα、分半信度、内容效度、结构效度、会聚效度和区别效度检验该量表信度和效度.结果 中文版DAS量表总Cronbach＇sα为0.934,分半信度为0.874.分量表得分与总量表之间的相关系数为0.639-0.922,确保了量表的内容效度;探索性因子分析显示,中文版DAS量表符合预设的6个维度结构,累计方差贡献率为56.371%;量表的会聚效度与区别效度定标试验成功率均为100%.结论 中文版DAS量表在职业驾驶员群体中具有较好的信度和效度,值得推广使用.

Objective To assess the reliability and validity of the Chinese version of Driving Anger Scale （DAS） in professional drivers in China and provide a scientific basis for the application of the scale in drivers in China. Methods Professional drivers, including taxi drivers, bus drivers, truck drivers and school bus drivers, were selected to complete the questionnaire. Cronbach＇s α and split-half reliability were calculated to evaluate the reliability of DAS, and content, contract, discriminant and convergent validity were performed to measure the validity of the scale. Results The overall Cronbach＇sα of DAS was 0.934 and the split-half reliability was 0.874. The correlation coefficient of each subscale with the total scale was 0.639-0.922. The simplified version of DAS supported a presupposed six-factor structure, explaining 56.371% of the total variance revealed by exploratory factor analysis. The DAS had good convergent and discriminant validity, with the success rate of calibration experiment of 100%. Conclusion DAS has a good reliability and validity in professional drivers in China, and the use of DAS is worth promoting in divers.
