To explore the relationship among disgust sensitivity， pathological narcissism and self?disgustin college students. ThePathological Narcissism Inventory， Disgust Scale?Revised Chinese and the Chinese version of Self?Disgust Scale were used to measure 536 college students in three universities in Anhui province. Pathological narcissism was positively correlated with disgust sensitivity（P<0.01）， and positively correlated with self?disgust（P<0.01）. The total score of disgust sensitivity was not correlated with that of self?disgust（P >0.05）， and the core disgust factors in the disgust sensitivity scale were significantly negatively correlated with that of self?disgust （P<0.01）. The total effect of disgust sensitivity on self?disgust was not significant， with the effect value of 0.040 （P>0.05）. The direct effect was significant，the effect value was -0.121（P<0.001）. The indirect effect was significant， with an effect value of 0.081（P<0.001）. Pathological narcissism has a masking effect between disgust sensitivity and self?disgust.
