目的: 对损耗敏感性量表( DSS) 中文版进行修订并检验其信效度。方法: 选取北京市某高校499 名研究生，随机分为两部分，一部分( n = 249) 用于条目分析与探索性因子分析，另一部分( n =250) 用于验证性因子分析与信效度检验; 以自我调节疲劳量表( SＲF-S) 、自我控制双系统量表( DMSCS)与青少年生活事件量表( ASLEC) 为效标检验效标效度; 2 周后随机选取其中280 名研究生进行重测以检验重测信度。结果: 量表中文版包含8 个条目，分为认知与行为2 个维度，共解释60. 7%的方差变异;验证性因素分析显示，双因素模型具有良好的拟合( χ2 /df = 4. 18，ＲMSEA = 0. 09，NFI = 0. 95，NNFI =0. 94，CFI = 0. 96，IFI = 0. 96，GFI = 0. 96，SＲMＲ = 0. 05) 。量表总分及2 个维度得分与SＲF-S 的各分量表得分、DMSC-S 冲动系统分量表得分、ASLEC 的各分量表( 除学习压力外) 得分均呈正相关( r = 0. 13 ～0. 55，均P ＜ 0. 001) 。总量表的Cronbach α 系数为0. 80，2 个维度的Cronbach α 系数为0. 79、0. 73; 总量表的重测信度为0. 52，2 个维度的重测信度为0. 46、0. 58。结论: 损耗敏感性量表中文版具有良好的心理测量学指标，适宜在研究生群体中使用。

Objective: To validate the Chinese Version of Depletion Sensitivity Scale ( DSS) and test its validity and reliability. Methods: A sample of 499 postgraduates coming from a university in Beijing was investigated with preliminary questionnaire，249 of them were assessed for exploratory factor analysis( EFA) and 250 of them were assessed for confirmatory factor analysis ( CFA) and testing of validity and reliability. The criterion validity was tested with the Self-Ｒegulatory Fatigue Scale ( SＲF-S) ，Dual-Mode of Self-Control Scale ( DMSC-S) and Adolescent Self-rating Life Events Check-list ( ASLEC) . Totally 280 students were retested for test-retest reliability with 2 week interval. Ｒesults: DSS was composed of 8 items in two factors，which were cognitive factor and behavioral factor. The two factors explained 60. 7% of the variances. The confirmatory factor analysis identified a two factor model ( χ2 /df = 4. 18，ＲMSEA = 0. 09，NFI = 0. 95，NNFI = 0. 94，CFI = 0. 96，IFI = 0. 96，GFI = 0. 96，SＲMＲ =0. 05) . The scores of depletion sensitivity were positively correlated with the scores of cognitive fatigue，behavioral fatigue，emotional fatigue poor control，punished，loss，relationship pressure and adaption problem ( r = 0. 13 － 0. 55，Ps ＜ 0. 001) . The Cronbach α coefficients were 0. 80 for the total questionnaire and 0. 79 and 0. 73 for the two factors. The test-retest reliability were 0. 52 for the total questionnaire and 0. 46 and 0. 58 for the two factors. Conclusion: It suggests that the Chinese version of Depletion Sensitivity Scale ( DSS) is reliable and valid enough to be applicable to measure the depletion sensitivity of Chinese graduate students.
