Bottom Line: Impulsive buying makes billions of dollars for retail businesses every year, particularly in an era of thriving e-commerce.In Study 1, we surveyed an online sample and found that while adaptive narcissism was not correlated with impulsive buying, maladaptive narcissism was significantly predictive of the impulsive buying tendency.By investigating 304 twin pairs, Study 2 showed that global narcissism and its two components, adaptive and maladaptive narcissism, as well as the impulsive buying tendency were heritable.

ABSTRACT
Impulsive buying makes billions of dollars for retail businesses every year, particularly in an era of thriving e-commerce. Narcissism, characterized by impulsivity and materialism, may serve as a potential antecedent to impulsive buying. To test this hypothesis, two studies examined the relationship between narcissism and impulsive buying. In Study 1, we surveyed an online sample and found that while adaptive narcissism was not correlated with impulsive buying, maladaptive narcissism was significantly predictive of the impulsive buying tendency. By investigating 304 twin pairs, Study 2 showed that global narcissism and its two components, adaptive and maladaptive narcissism, as well as the impulsive buying tendency were heritable. The study found, moreover, that the connections between global narcissism and impulsive buying, and between maladaptive narcissism and impulsive buying were genetically based. These findings not only establish a link between narcissism and impulsive buying but also help to identify the origins of the link. The present studies deepen our understanding of narcissism, impulsive buying, and their interrelationship.

Measured variables are depicted in rectangles. Latent factors A (additive genetic factor), C (shared environmental factor), and E (non-shared environmental factor) are presented in circles.

Mentions: Finally, for the multivariate analysis of adaptive narcissism, maladaptive narcissism, and impulsive buying, we used Cholesky decomposition. The multivariate model parameterized the variances for and the covariances among adaptive narcissism, maladaptive narcissism, and impulsive buying into three groups of genetic and environmental effects (Figure 2). A1, C1, and E1 represent genetic, shared environmental, and non-shared environmental influences common to all measures; A2, C2, and E2 represent influences common to the second and the last variables in the model; and A3, C3, and E3 represent influences unique to the last variable. Notably, A1, C1, and E1 also include influences specific to the first variable in the model, whereas A2, C2, and E2 also include influences specific to the second variable in the model. We tested two Cholesky models. As personality theories typically hypothesize traits as causes of behaviors, rather than the reverse (Allport, 1937; McCrae and Costa, 1999), we entered impulsive buying last in both models. In one model (Figure 2A), we entered adaptive narcissism first and maladaptive narcissism thereafter, so that we could examine the specific genetic and environmental influences from maladaptive narcissism to impulsive buying. In the other model (Figure 2B), we entered maladaptive narcissism first and adaptive narcissism second, so that we could also examine the specific genetic and environmental influences from adaptive narcissism to impulsive buying. The two models operate in the same way except that the order of entering the variables is reversed. From the model paths, we can estimate genetic, shared, and non-shared environmental effects on adaptive narcissism, maladaptive narcissism, and impulsive buying. We also can estimate correlations between these effects (i.e., genetic, shared, and non-shared environmental correlations) based on the model paths. As with the previous analyses, the full ACE model and the sub-models were systematically tested.
