Relationship between extroversion and social use of social networking sites

We investigated a comprehensive model to integrate the negative linear association as well as the positive linear association between extroversion and the social use of social-networking-site behaviors. We examined the possibility of a curvilinear relationship between social use of networking sites and extroversion, revealing U-shaped curvilinear relationships between extroversion and total number of friends, browsing, and leaving comments after controlling for the linear relationship. These findings underscore the importance of considering a possible curvilinear relationship between extroversion (individual differences) and related behaviors in relation to social use of social networking sites.
