In this study, we explored the motivations and the effects of selfie taking, posting, and viewing. To understand the selfie phenomenon, we conducted in-depth interviews with 16 American and Chinese students. The findings suggest that the selfie phenomenon among American students is not necessarily related to narcissism and low self-esteem, as argued in many previous literatures. Contrarily, selfie usage among Chinese students is more associated with narcissism (self-indulgence in recreational selfie-taking) and impression management (selfie-editing to improve online self-image). In the general, selfie taking, viewing, and posting behaviors could be conceptualized as more than just a display of narcissism, but also as a new way of communication, life-recording, online impression management, and relationship management. Cultural differences between American and Chinese students' use of selfies are also discussed.
