Examining Information Disclosure Behavior on Social Network Sites Using Protection Motivation Theory, Trust and Risk

This paper reports on an empirical study that investigates the information disclosure behavior on Social Network Sites (SNS) focusing on undergraduate University students as our population. Although much have been reported on the issue of information privacy or privacy leakage on SNS, very few have employed the Protection Motivation Theory (PMT) as a framework to understand SNS user’s behavior related to information disclosure. In this study, the PMT incorporated with trust and risk factor, has revealed that trust on SNS and perceived benefits influenced information disclosure behaviour. Our findings showed that all PMT constructs are significantly related to privacy concern. However, privacy concern and perceived risk were found not related to information disclosure behaviour. Using self-administered questionnaire, 486 undergraduate students from five different universities in Malaysia were involved in this study.

An Empirical Study of the Factors Influencing Information Disclosure Behaviour in Social Networking Sites

Since the introduction of social networks over a decade ago, a number of research has focused on understanding the behaviour of social network user in disclosing information over the Social Network Sites (SNS). Although the issue of privacy breach on SNS has been widely reported, very few studies have used the Protection Motivation Theory (PMT) as a framework to understand SNS users behaviour related to information disclosure. This study employed the PMT, incorporated with trust, perceived risk and privacy concern to investigate the factors affecting information disclosure behaviour on SNS among 486 undergraduate students in Malaysia. Our findings showed that perceived risk, perceived benefits and trust on SNS influenced individual information disclosure behaviour. However, privacy concern was found not related to information disclosure behaviour.
