Abstract-In recent years, Social Networking Sites (SNSs) have become a major communication vehicle in all societies. Facebook has become the most popular social networking site with more than 2.2 billion users. The pleasure that Facebook has brought has led to some addictive behavior among its users. This study employed the Bergen Facebook Addiction Scale to investigate Facebook addiction among students. In this study, we selected a sample of 441 students in Universiti Teknologi Malaysia as respondents. Results show that 47% of the participants were addicted to Facebook. This ratio is almost the same among postgraduate and undergraduate students, and interestingly, among Malaysian and non-Malaysian. Much speculated factors such as religion, level of income, ego strength and locus of control do not show significant influence on the risk of Facebook addiction. Lastly, the results suggest that as people spend more time on Facebook, there is a greater chance of addiction.Index Terms-Facebook addiction, social networking sites, students. I.
