To improve under- standing of the relationship between narcissism and SNS use, as well as the implications of differences in definition and measurement, we examine two ways of measuring Facebook and Twitter use by testing the hypothesis that SNS use is positively associated with narcissism. We also explore the relation between these types of SNS use and different components of narcissism within college students and gen- eral adult samples. Our findings suggest that for college students, posting on Twitter is associated with the Superiority component of narcissistic personality while Facebook posting is associated with the Exhi- bitionism component. Conversely, adults high in Superiority post on Facebook more rather than Twitter. For adults, Facebook and Twitter are both used more by those focused on their own appearances but not as a means of showing off, as is the case with college students. Given these differences, it is essential for future studies of SNS use and personality traits to distinguish between different types of SNS, different populations, and different types of use.

SNS currently account for nearly one quarter of the total time spent online, and almost 80% of Internet users report some SNS use (Comscore, 2011). These sites have become one of the pri- mary venues in which people interact with one another, establish their identities and friendships, and influence peers. This has at- tracted considerable scholarly attention, much of it devoted to investigating relationships between psychological traits and the use of such sites. A growing number of these studies focus on how narcissism and behavior on SNS are related (Bergman, Fear- rington, Davenport, & Bergman, 2011; Ong et al., 2011; Ryan & Xe- nos, 2011), surmising that such sites may be products of and/or contribute to a growing culture of self-centeredness, particularly among college students. In fact, cross-temporal meta-analyses of narcissism and empathy levels among college students over the past three dec- ades have found decreases in empathic concern (i.e., sympathy for the misfortunes of others) along with increases in narcissism (Konrath, O’Brien, & Hsing, 2011; Twenge, Konrath, Foster, Campbell, & Bushman, 2008). Though these trends pre-date the popularization of SNS, the rate of decline in empathic concern has accelerated since 2000 (Konrath, O’Brien, & Hsing, 2011), prompting researchers to speculate that the rise of SNS may have enabled narcissistic individuals to seek veneration on a grander scale than would otherwise be feasible (Konrath, O’Brien, & Hsing, 2011). Narcissism is a complex construct and represents multiple traits, indicative of both healthy and unhealthy behaviors (Kubar- ych, Deary, & Austin, 2004) that may explain the motivations be- hind SNS use. Therefore, conceptualizing narcissism as just a single construct might cause us to misunderstand the ways in which SNS are used to satisfy various psychological needs. Re- search has in fact already begun to examine how unhealthy com- ponents of narcissistic personality relate to behavior on Facebook (Carpenter, 2012). The current study pursues this line of research by investigating how both healthy and unhealthy components of narcissism inform Facebook and Twitter use. We proceed by first discussing narcis- sism and how it relates to SNS use. Treating all SNS as a single con- cept rather than differentiating among specific types of SNS such as Twitter and Facebook may elide important differences in motiva- tions people have for using SNS. Therefore, key differences in the affordances of Facebook and Twitter relevant to narcissism re- search are then discussed, highlighting the ways in which the ob- 0747-5632/$ - see front matter Ó 2013 Elsevier Ltd.
