Narcissism is a personality trait that has potentially important effects on career development outcomes, yet empirical research on this issue is sparse. The present study explored the relationships between narcissism and two indicators of career success (i.e., salary and career satisfaction) among a group of young professionals (. N=. 314). We assessed a model proposing that the effect of narcissism on career success is mediated by increased occupational self-efficacy beliefs and career engagement. While correlations between narcissism and the two indicators of career success were minimal, the results showed a significant indirect effect on salary via occupational self-efficacy and indirect effects on career satisfaction via self-efficacy and career engagement. We discuss the results regarding insights into why narcissism may lead to career success.
