Social media are playing an increasing role in today’s living. The social media platforms allow users to search, create, share, collaborate, and organise contents among them, and at the same time provide virtual self-presentation and self-disclosure of oneself. Social media were also claimed to give implications to human beings with regards to personality, yet these variables have not much been emphasised in previous studies. Thus, it is important to highlight the implications of social media on users’ personality. Given the issues and challenges faced by the country in profiling the adoption of social media and its implications in view of the perspective of personality, it is timely and significantly important to undertake this research in Malaysia. The objective of this chapter is to discuss a research conducted recently to determine the relationships between social media and personality traits. The specific objectives of this study are to identify the profile of social media adoption among students in Malaysia, including duration, frequency of use, purpose, and person/s that introduced the social media, and to determine the relationships between social media and personality traits.
