Mediators of the association between narcissism and compulsive buying: the roles of materialism and impulse control.

Building upon past research about the guiding values and self-regulation difficulties of people with narcissistic personalities, this study tested a model of the association between narcissism and compulsive consumption. In data obtained from a sample of undergraduate consumers (N=238) with varying degrees of spending problems, positive associations emerged between narcissism, materialism, and compulsive buying. Impulse control was negatively correlated with each of these variables. Mediation tests revealed that both impulse control and materialism accounted for significant portions of the shared variance between narcissism and compulsive consumption. These findings highlight the importance of both personal values and impulse control as correlates of addictive buying. They also add to growing evidence that people who are relatively narcissistic are poor self-regulators who may be at risk of developing a variety of addictive behaviors.
