While prior research has examined the relationship between narcissism and self-promoting behaviors on social media (e.g., posting selfies), little is known about the extent to which individuals' level of narcissism relates to how involved they are in other people's feedback (e.g., comments and "likes") received on their selfies, or how observant and responsive they are to other people's selfie postings. The present study investigates how narcissism relates to such selfie-related behaviors, as well as overall evaluation of selfie-posting behavior and intention to post selfies in the future. By employing a total of 315 Korean subjects who take and post selfies on social networking sites, the present study indicates that individuals higher in narcissism are more likely to evaluate selfie-posting behavior favorably, be involved in the feedback provided by others, and be observant of other people's selfies. However, level of narcissism did not moderate the relationship between how much one observes others' selfies and the likelihood of providing a comment or "like" on other people's selfies.
