Personality traits and self-presentation at Facebook ∗

• Extraversion was a positive predictor of photo uploads, status updates, and number of friends at FB Wall.
• Narcissism was a positive predictor of status update at FB Wall.
• Extraversion was a positive predictor of Like, Comment, and Share at FB News Feed.
• Openness was a negative predictor of clicking Share at FB News Feed.
• Conscientiousness was a negative predictor of writing Comment at FB News Feed.

The current study explores the relationship between personality traits and self-presentation at Facebook. An online survey of Facebook users was conducted. The results suggest that extraversion was positively related to self-presentation both on Wall and at News Feed. Extraverts uploaded photos and updated status more frequently, and had more friends displayed on Wall than introverts. Besides, extraverts clicked Like, wrote Comment and clicked Share at News Feed more frequently than introverts. Moreover, narcissists with high rivalry frequently updated their Status on Wall. In addition, neuroticism and conscientiousness were negatively related to writing Comment at News Feed. Lastly, openness to experience was negatively related to clicking Share at News Feed. The results and implications are discussed in conjunction with previous research. Suggestions for future research are provided.
