In this study, I challenged to identify the mediating effect of experiential avoidance in relation between covert narcissism and career indecision. In order to achieve this, I conducted a survey of 508 students who are currently attending four-year and two-year colleges. Korean Career Indecision Inventory, Covert Narcissism Scale and Acceptance & Action Questionnaire-16 were used for the questionnaires. The results are as follows. First, there were significant positive correlations among covert narcissism, experiential avoidance and career indecision. Second, the relationship between covert narcissism and career indecision was partially mediated by experiential avoidance. I adopted partial mediation model as a final model and found the mediating effect of experiential avoidance significant. Not only did covert narcissism affect career indecision directly, but also affected career indecision indirectly through experiential avoidance. Third, I conducted a multi-group analysis using a structural equation modeling to verify if this study model indicated significant difference according to the college types. As a result, there was a statistically significant difference in the path from covert narcissism to experiential avoidance between four-year college group and two-year college group. Based on these results, I discussed the significance, limitations of this study and the suggestions for follow-up study.
