Studies that specifically discuss the formation of autonomous motivations of users of social networking services (SNSs) and how such motivation influences SNS user intention to disclose personal location-related information (PLRI) are absent from the literature. Consequently, this study, based on the self-determination theory and the information system success (ISS) model, investigates the relationships among key system-related quality factors, SNS users’ autonomous motivations and user satisfaction regarding an SNS, and their intentions to disclose PLRI. Survey data collected from 514 students at six universities were analyzed to validate our research model. Research results show that three system-related quality factors have different influences on user satisfaction and autonomous motivation, while both autonomous motivation and user satisfaction are significant antecedents of user intention to disclose PLRI. The research results have extended the application and advanced the understanding of ISS model and self-determination theory in the context of SNS.
