Narcissism and counterproductive work behavior: Do bigger egos mean bigger problems?

In accordance with the theory of threatened egotism and aggression, the relationships among narcissism, trait anger, job constraints and counterproductive work behavior (CWB) were explored in a questionnaire study. The results were supportive of the hypotheses that narcissism would relate to trait anger, job constraints, and CWB and that the relationship between narcissism and CWB would be mediated by anger. In addition, narcissism was found to moderate the relationship between job constraints and CWB, such that individuals high in narcissism reported more CWB when constraints were high, than individuals low in narcissism.
