Factors Influence Self-Disclosure Amount in Social Networking Sites ( SNSs )

Social networking sites (SNSs) are increasingly used on daily basis. SNSs users connect each other via social networks’ platform with shared interests and values based on other users’ self-disclosed personal information. Generally, users would like personal information to be visible to only their families, close friends and not by unknown persons or strangers. There are some cases that users wish to reveal their information to strangers who are part of a network so in this case the information that disclosed may be visibly vulnerable for hacking. The range of these privacy risks from identity thieves to both physical stalking and online; and form embarrassment to price discrimination and blackmailing. Several researches identified an increasing privacy problem that exists within SNSs. Some studies have shown how easily strangers can extract personal data about users from the network. Other studies have found that an extremely small percentage of SNSs users change their permissive default privacy settings. In this paper, we propose a model of self-disclosure with six hypotheses, and we divided the model into two main categories: (a) hypotheses that have positively related to self-disclosure amount such as perceived enjoyment and ease of use, and (b) hypotheses which have negatively related to self-disclosure which mainly fall under privacy concerns such as perception of damage and likelihood. Our study established several important concepts: privacy concerns of SNSs users decrease online community self-disclosure; perceived enjoyment increases self-disclosure; SNSs providers trust increases self-disclosure; damage and likelihood beliefs decrease selfdisclosure. Meanwhile, perceived ease of use increases self-disclosure.
