2Information disclosure of social media users: does control over personal information, user awareness and security notices matter? Abstract Purpose -Our study bridges the gap in the existing literature by exploring the antecedents of information disclosure of social media users. In particular, the paper investigates the link between information disclosure, control over personal information, user awareness and security notices in the social context, all of which are shown to be different from existing studies in e-commerce environments.Design/methodology/approach -We collected and analysed data from 514 social network users. The model is estimated using OLS and robust standard errors are estimated using the Huber-White sandwich estimators.Findings -Our results show that in social networking contexts, control over personal information is negatively and statistically associated with information disclosure. However, both user awareness and security notices have a positive statistical effect on information disclosure.Originality/value -Whilst research on issues of individual information privacy in ecommerce is plentiful, the area of social networking and privacy protection remains underexplored. This paper provides a useful model for analysing information disclosure behaviour on social networks. We discuss the practical implications of our findings for actors in social media interactions.
