Internet usage has become a big part of many people’s lives, and among the many uses Social Networking Sites (SNS) have become very prevalent. How privacy concerns, trust and control are affecting SNS usage and self-disclosure has become an important question for many people. I compiled a questionnaire and analyzed it for reliability. Then it was used to determine the relationship between these constructs and compared to the behavioral data that was collected from participant’s Facebook pages. The results showed that privacy concerns do not affect SNS usage or self-disclosure. Trust and control were significantly correlated with specific autobiographical memories, but trust was negatively correlated.

Based on these results trust and control are linked with SNS usage and self-disclosure, while privacy concerns are not affecting them
