Abstract: 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.
