不确定感忍耐性量表中文版的信效度分析

The reliability and validity of the Chinese version of the intolerance of uncertainty scale

目的 分析不确定感忍耐性量表（Intolerance of Uncertainty Scale,IUS）中文版的信效度.方法 问卷调查878名大学生,应用SPSS13.0以及Amos17.0进行信效度分析.结果 项目分析和探索性因素分析表明,不确定感忍耐性量表中文版共包括24个项目,四个因子,四个因子可以解释总方差的50.355％,验证性因素分析进一步验证了四维的量表结构（x2=660.645,x2/df=2.686,NFI=0.806,NNFI=0.817,CFI=0.837,RMSEA=0.071）.不确定感忍耐性量表中文版得分均与忧虑、状态焦虑、特质焦虑、抑郁得分显著负相关（r=-0.288～-0.481,P＜0.001）,表明该量表具有较好的效标关联效度.不确定感忍耐性量表中文版的内部一致性系数为0.889,165名被试相隔1个月的重测信度为0.687.结论 不确定感忍耐性量表中文版符合心理测量学要求,可作为评估中国大学生不确定感忍耐性的测量工具.

Objective To analyze the reliability and validity of the Chinese version of the intolerance of uncertainty scale （IUS）.Methods 878 college students were investigated,then the data were analysis by SPSS13.0 and Amos17.0.Results The project analysis and exploratory factor analyzed showed that,the Chinese version of the intolerance of uncertainty scale consisted of 24 projects and four dimensions,which could account for over 50.355% of tolal varance.The confirmatory factor analysis further revealed the structure of four-dimensional scale （x2 =660.645,x2/df =2.686,NFI =0.806,NNFI = 0.817,CFI =0.837,RMSEA =0.071）.The score of the Chinese version of the intolerance of uncertainty scale was significantly correlated with all criterion,and the correlation coefficients to criterion ranged from-0.288 to-0.481,so the scale had the better criterion validity.The Cronbach＇s a coefficient of the Chinese version of the intolerance of uncertainty scale was 0.889,and the test-retest stability coefficient was 0.687.Conclusion The Chinese version of the intolerance of uncertainty scale has good psychometric quality,and can be used in Chinese college students.
