Are You a Facebook Narcissist?

Do you regularly update your Facebook status, write wall posts, or publish overtly sexy profile photos? If you answered "yes" to any of these questions, you may be a Facebook narcissist, according to new research.

"Self-Presentation 2.0: Narcissism and Self-Esteem on Facebook" out of York University in Toronto found that greater online activity on Facebook is correlated with narcissism and low self-esteem.

Psychologist Soraya Mehdizadeh analyzed 100 Facebook users' profiles against their real-world personalities. After having 50 male and 50 female student participants answer questions about their demographics, Facebook activity, self-esteem and narcissism, Mehdizadeh rated each student's page for self-promotional content, assessing the "About Me" section, photos, notes and status updates.

In a separate study out of San Diego State University, some 60 percent of college students agreed with the statement "people in my generation use social networking sites for self-promotion, narcissism, and attention-seeking."
