Abstract: To explore the mediation effects of intolerance of uncertainty and selfesteem on the relationship of negative perfectionism and social anxiety, 365 college students were investigated with Almost Perfect Scale, Selfesteem Scale, Intolerance of Uncertainty Scale and Interaction Anxiousness Scale. The results were as following. (1) Correlation analysis showed that social anxiety was positively correlated with intolerance of uncertainty and negative perfectionism, and negatively correlated with selfesteem; selfesteem was negatively correlated with intolerance of uncertainty and negative perfectionism, intolerance of uncertainty was positively correlated with negative perfectionism. (2) Hierarchical multiple regression analysis showed that the predictive effect of negative perfectionism on social anxiety dropped when intolerance of uncertainty or selfesteem entered in the regression equations. So intolerance of uncertainty and selfesteem partially mediated the effect of negative perfectionism on social anxiety. (3) Structural equation modeling showed that intolerance of uncertainty exerted indirect effect on social anxiety. So negative perfectionism affected social anxiety through mediating effect of selfesteem and intolerance of uncertainty.

Key words: negative perfectionism; social anxiety; intolerance of uncertainty; selfesteem
