Narcissism and Commitment in Romantic Relationships: An Investment Model Analysis

Two studies examined narcissism and commitment in ongoing romantic relationships. In Study 1, narcissism was found to be negatively related to commitment. Mediational analyses further revealed that this was primarily a result of narcissists’ perception of alternatives to their current relationship. Study 2 replicated these findings with an additional measure of alternatives. Again, narcissists reported less commitment to their ongoing romantic relationship. This link was mediated by both perception of alternatives and attention to alternative dating partners. The utility of an interdependence approach to understanding the role of personality in romantic relationships is discussed.
