目的:检验修订版多维度驾驶风格量表在我国驾驶员测量中的信度、效度和适用性.方法:采用“滚雪球”方法在全国20个大中城市先后分两次选取总共655名驾驶员参加本次研究,样本分为两部分.结果:样本1的测量结果显示:修订后的驾驶风格量表由24个题目组成,分为5个因素,累计贡献率为54.27%.量表各因素与总分的相关系数在0.60~0.77之间,均P<0.001.量表总的内部一致性系数为0.86,各个因素的内部一致性系数在0.70~0.82之间.样本2的测量结果验证了修订版驾驶风格量表的结构有效性和适用性.结论:修订版驾驶风格量表具有良好的信度和效度,可以作为今后进一步研究的测量工具.
Objective To test the reliability,validity and applicability of the revised version of Multidimensional Driving Style Inventory (MDSI-C) among Chinese drivers.Methods 655 drivers from 20 major cities participated and completed the MDSI in two studies.Results The final version of MDSI-C consisted of 24 items,which was divided into 5 factors.The factors'ratio of cumulative contribution was 54.27 %,indicating that it had good construct validity.Pearson correlations between the factors and the whole inventory was from 0.60 to 0.77,all ps < 0.001.The Cronbach's α of the whole inventory was 0.86,and 0.82,0.75,0.73,0.72,0.70 for the factors,respectively.In addition,other results from the drivers,who have records of traffic violations,showed that the MDSI-C suited for chinese drivers well.Conclusion Both the reliability and validity of MDSI-C met the criteria of psychometrics,and it can be used as a tool to assess Chinese drivers'driving styles in the future researches.
