驾驶安全态度量表的修订及信效度检验

Reliability and Validity of Driving Safety Attitude Scale in Chinese Drivers

目的检验修订版驾驶安全态度量表在我国驾驶员中的信度、效度和适用性。方法采用修订版安全态度量表和驾驶行为量表对202名驾驶员进行了测量,得到最终量表。结果修订版驾驶安全态度量表由18个题目组成,分为道路畅通与规则遵守、超速驾驶、激情驾驶三个维度,可以解释驾驶安全态度63.24%的变异。量表各因素与总分的相关系数在0.606~0.759之间,P<0.001。量表总的内部一致性系数是0.928,各维度内部一致性系数在0.876~0.884之间。三个维度均与驾驶行为量表中的亲社会驾驶行为维度呈显著负相关、与攻击性驾驶行为维度呈显著正相关。结论修订版驾驶安全态度量表信效度良好,可以用来测量我国驾驶员的驾驶安全态度。

ObjectiveObjective To test the reliability, validity and applicability of the revised version of driving safety attitude scale （DSAS） among Chinese driver measurement. Methods 202 drivers were measured with DSAS and driving behavior scale and the revision of the scale was obtained after analysis. Results The revised version of the driving safety attitude scale was composed of 18 subjects, who were divided into three dimensions： road smoothing and rule compliance, speeding driving and passion driving. The explanatory rate of variance was 63.24%. The correlation coefficients between the factors and total scores ranged from 0.606 to 0.759, all ps〈 0.001. The Cronbach＇s α of the whole inventory was 0.928, and all factors were between 0.876 and 0.884. All of the three dimensions were negatively correlated with pro-social driving behavior dimension in driving behavior scale, and had significant positive correlation with dangerous driving behavior dimension. ConclusionThe reliability and validity of DSAS were good, and it can be used as a tool to measure Chinese driver＇s driving attitude.
