The purpose of this study is to examine the relationship between using Facebook and narcissism among Bahirdar university students. Two research questions are identified. First, the study sought to determine if Facebook check-in frequency, duration of Facebooking, frequencies of self-presenting activities, and number of friends predicts narcissism. Second, the study looks for the meaning that self-presenting activities in Facebook may have in relation to narcissism. A total of 201 psychology students have participated in the study. A questionnaire that measures the Facebook utilization of participants and the Narcissistic Personality Inventory (NPI-40) are administered for participants. Facebook utilization variables are regressed to determine their predictive effect on narcissism. And, the Facebook profile pages of outliers are analyzed for their meaningful contents that may imply narcissism. The result indicates that sharing frequency (one of the self-presenting activities), check-in frequency, and number of friends significantly predicts narcissism among Bahirdar university students, F(3,197) = 10.072, p<.001. And the Facebook pages of outliers signifies that posting selfies and updating pictures can reinforce narcissism as they facilitate exchange of compliments.
