摘要目的 探讨驾驶员压力量表中文版的信度和效度.方法 采用驾驶员压力量表(DSI)中文版调查300名汽车驾驶员,评定该量表的结构效度、内容效度和内部一致性信度.结果 (1)除题项9,16和18外,其余题项均有较好的鉴别力.(2)量表由6个因素构成,可解释项目总方差的45.277%.各因素与量表总分之间相关显著(r=0.241～0.622,P<0.01).(3)量表分半信度为0.557,6个因素的Cronbach α系数分别为0.569,0.631,0.799,0.675,0.587和0.685.结论 DSI具有较好的信度和效度,是测试汽车驾驶员压力的有效工具.

abstractsObjective To explore the reliability and validity of the Chinese version of driver stress inventory (DSI). Methods Three hundred drivers were investigated with DSI. The structure validity,content validity and internal reliability were examined. Results (1)Except items 9,16 and 18, the others had good discrimination. (2) Six factors were extracted which could explained 45.277% of the total variance. The six factors were significantly correlated with DSI total score(r = 0.241～0.622, P<0.01). (3)The spilt-half reliability was 0.557, The six factors ' Cronbach alphas were 0. 569, 0. 631, 0. 799, 0. 675, 0. 587 and 0. 685 respectively. ConclusionDSI has good reliability and validity, and is an effective instrument to test drivers' stress.
