目的探讨完美主义与自我损耗的关系,以及生活方式现实-理想差异在完美主义与自我损耗间的中介作用。方法 2014年11月,采用便利抽样的方法,抽取北京市中国人民大学和中央财经大学在校大学生266人,采用Frost多维度完美主义量表、自我调节疲劳量表和改编的生活方式现实-理想差异问卷调查完美主义、自我损耗及生活方式现实-理想差异。采用SPSS 17.0统计学软件进行数据分析,Frost多维度完美主义量表与自我调节疲劳量表得分的相关性采用Pearson直线相关分析;以Frost多维度完美主义量表得分为自变量,自我调节疲劳量表得分为因变量,生活方式现实-理想差异为中介变量,采用三步中介回归法分析其之间的关系;以Frost多维度完美主义量表总分的上、下27%为分界,将受试者分为完美主义高分组（n=76）与完美主义低分组（n=75）,比较两组自我调节疲劳量表及生活方式现实-理想差异得分的差异。结果 Frost多维度完美主义量表总分与自我调节疲劳量表总分及其认知分量表、行为分量表、情绪分量表得分均呈正相关（P〈0.05）。三步中介回归法结果表明,生活方式现实-理想差异在完美主义影响自我损耗中的中介作用显著（P〈0.05）。完美主义高分组与完美主义低分组自我调节疲劳量表总分及认知分量表、行为分量表、情绪分量表、理想生活方式、生活方式现实-理想差异得分比较,差异均有统计学意义（P〈0.05）;而现实生活方式得分比较,差异无统计学意义（P〉0.05）。结论个体的完美主义特质可以正向预测其自我损耗程度;生活方式现实-理想差异在完美主义特质对自我损耗程度的影响中起部分中介作用。

Objective To explore the relationship between perfectionism and ego-depletion,and the mediating effect of lifestyle actual-ideal self-discrepancy between them.Methods By convenient sampling,the FMPS（ Frost Multidimensional Perfectionism Scale）,SRF-S（ Self-regulatory Fatigue Scale） and self-edited lifestyle actual-ideal self-discrepancy scale were administered to 266 university undergraduate students from Renmin University of China and Central University of Finance and Economics in November 2014 for investigating the level of perfectionism,ego-depletion and lifestyle actual-ideal self-discrepancy.The data were processed by SPSS 17.0.Pearson linear correlation analysis was used to analyze the correlation between FMPS scores and SRF-S scores.With the FMPS scores as independent variable,SRF-S scores as the dependent variable,lifestyle actual-ideal self-discrepancy as intermediary variable,we analyzed the relation between the three by three-step mediation regression procedure.In terms of the total score of FMPS,subjects who scored the top 27% and the bottom 27% were assigned to the high-score perfectionism group（ n = 76） and low-score perfectionism group（ n = 75）.The scores of SRF-S and lifestyle actual-ideal self-discrepancy were compared between the two groups.Results Significant positive correlation was found between FMPS and SRF-S including its three subscales,cognitive subscale,behavioral subscale and emotional subscale in terms of scoring（ P〈0.05）.Results of three-step mediation regression procedure showed that lifestyle actual-ideal self-discrepancy had a significant partial mediating effect on the relationship between perfectionism and ego-depletion（ P〈0.05）.There were significant differences in SRF-S,and its cognitive subscale,behavioral subscale and emotional subscale,ideal lifestyle,lifestyle actual-ideal self-discrepancy in scoring between the high-score perfectionism group and low-score perfectionism group（ P〈0.05）.However,the difference was not statistically significant in score of actual lifestyle（ P〈0.05）.Conclusion Perfectionism may positively predict the degree of ego-depletion,in which lifestyle actual-ideal self-discrepancy has a partial mediating effect.
