【摘要】 目的:我们生活中经常有一些无法确定的事件,正如我们平时所说的"计划永远赶不上变化"。对于这些不确定事件,每个个体的容忍程度是不一样的。Freeston等在1994年提出无法忍受不确定性概念时,将它定义为对日常生活中不确定性的认知、情绪和行为反应。有学者研究发现,不确定的容忍程度往往跟人的焦虑、担忧、抑郁心境有关系。面对不确定的情况,有些个体就会容易忽视客观事实,高估事情的不确定性,产生担心和焦虑的情绪。有学者提出的广泛性焦虑症的认知模型中,无法忍受不确定性被认为在广泛性焦虑症的形成和维持中起着核心作用。担心(worry)的定义中就提到不确定的事件可能是引发个体担心的主要原因。最初的无法忍受不确定性的量表也是由Freeston编制,由27个项目组成,采用Likert 5级别评分,得分越高表示不确定性容忍度水平越低。Buhr and Dugas在2002年对两种版本进行了校验,具有良好的内部一致性和重测信度。杨智辉在2013年将27个条目的英文版翻译为中文版,并进行了校验。鉴于无法忍受不确定量表经常不是单独使用,常常需要跟焦虑、抑郁、担忧、压力等量表混合使用,所以27个条目相对有点多,容易引起被试答题的倦怠性,所以Norton等人将27个条目的原始量表删减为12个条目,具有良好的信效度,因子分析结果为两因子结构。但是目前国内中文版的只有27条目,所以本次研究将英文版的12条目的无法忍受不确定量表修订为中文版,以方便国内学者使用。方法:采用无法忍受不确定量表(IUS)简版、焦虑自评量表(SAS)、抑郁自评量表(SDS)、宾州担忧量表中文版(PSWQ)对998名在校大学生进行施测,并对其中的306名学生用无法忍受不确定量表(IUS)进行5周后重测。结果:IUS量表内部一致性信度检验结果科隆巴赫系数为0.92。对样本的初测分数(32.65±7.35)和重测分数(33.31±7.98)进行配对样本t检验,结果发现它们之间没有显著差异(t(306)=-6.815,P>0.05)。初测和重测的组内相关系数(IntraclassCorrelation Coeffi-cient,ICC)较高(r=0.89,P<0.001)。经过主成分分析和正交旋转,根据特征值大于1的原则和碎石图显示抽取2个因素最为合适。结果表明,特征根为2.52和1.08,累积方差贡献率为57.38%。各题项的因素负荷在0.62-0.72之间,效标效度检验显示,IUS与SAS、SDS、PSWQ得分均成正相关(r=0.51、0.58、0.57,均P<0.01),与IUS-27量表效标关联系数达到0.95,解释了IUS-27总分的93.1%的方差。回归分析显示,在控制了焦虑和抑郁后,无法忍受不确定性主要对担忧有贡献。结论:无法忍受不确定量表(IUS)中文版具有良好的心理测量学指标,适宜在中国大学生群体中使用。更多还原

【Abstract】 Objective:Individuals will be easy to ignore the objective facts,overestimate what uncertainty,fear and anxiety.Some scholars put forward the cognitive model,the generalized anxiety can’t stand uncertainty is considered in the formation of the generalized anxiety and maintain plays a central role.Concern(worry) mentioned in the definition of uncertainty of events is probably the main reason for the individual concerned.The original can’t stand uncertainty scale is also formulated by Freeston,composed of 27 project,using a Likert 5 rating,the higher the score lower said uncertainty tolerance level.Buhr and Dugas two versions for the calibration in 2002,it has good internal consistency and reliability.Zhi-hui Yang use 27 items in English version translated into Chinese in 2013,and has carried on the check.Given the intolerable uncertainty scale is often not used alone,often need to anxiety,depression,worry,stress scale,such as mixing,27 entries is relatively a bit more,so try to be the answer of burnout,so the original scale of Norton and others will be 27 items cut for 12 items,good,reliability and validity of factor analysis results for two factor structure.But at present domestic Chinese version only 27 items,so this research will can’t stand uncertainty scale of 12 items in English revision for Chinese version,facilitate the use of Chinese scholars.Method:998 university students were assessed with The intolerable of uncertainty scale(IUS) simple version,self-evaluation of anxiety scale(SAS),self-evaluation of depression scale(SDS),the Chinese version of The Peen State Worry Questionnaire(PSWQ),Of these students,the 306 students were retest with intolerable uncertainty scale(IUS) after five weeks.Results:IUS scale internal consistency reliability test results cologne Bach coefficient of 0.92.Test scores at the beginning of sample(32.65-7.35) and test scores(33.31-7.98) for paired samples t test,the results showed that there were no significant differences between them(t(306)= 6.815,P > 0.05).Preliminary survey and retested intraclass correlation coefficient(IntraclassCorrelation Coeffi-cient,ICC) high(r = 0.89,P < 0.001).Through principal component analysis and orthogonal rotation,based on the principle of eigenvalues greater than 1 and gravel figure shows take two factors is most appropriate.The results show that the characteristic root of 2.52 and 1.08,cumulative variance contribution rate of 57.38%.Each item of the factors of load between 0.62-0.72,criterion validity test shows,IUS and SAS,SDS,PSWQ is closely relative to score(r = 0.51,0.58,0.57,P < 0.01),and IUS-27 scale criterion correlation coefficient is 0.95,explains the variance of IUS-27 about 93.1%Regression analysis shows that after controlling for anxiety and depression,and can’t stand uncertainty mainly contributes to the concerns.Conclusion:The Chinese version of IUS has adequate psychometric quality,which can be used to assess mind-wandering in Chinese university students.更多还原
