The effect of NPD on social network formation and information sharing behavior

This study determines how narcissistic personality disorder (NPD) in SNS affects social network formation behavior and information sharing behavior in SNS. The results of analysis are as follows. First, rate of use from the extent of SNS usage and bonding social capital from social capital turned out to have significant effects on internally-driven narcissistic personality disorder in SNS. Furthermore, bridging social capital turned out to have significant effects on externally-driven narcissistic personality disorder. Second, internally-driven narcissistic personality disorder had significant effects on out-degree (following friends in social network) and in-degree (accepting the following of friends). Third, internally-driven narcissistic personality disorder had significant effects on information service sharing behavior and self-expressive sharing behavior. Considering the above, internally-driven narcissistic personality disorder affected by strong ties tends to show information sharing behavior, while externally-driven narcissistic personality disorder affected by weak ties did not have significant effects on information sharing behavior.
