Purpose: Social networking sites are highly popular worldwide. Facebook is the most popular and most visited social networking site in Taiwan. Ensuring that users continue to visit the website is vital for Facebook’s ongoing viability. We investigated the factors that determine a user’s intention to continue using a networking website. Methods: A structured questionnaire survey was conducted to investigate the following eight factors that might affect a user’s continued use of Facebook: perceived ease of use, perceived playfulness, trust, satisfaction, community switching cost, privacy policy, attitude of behavior, and subjective norms. Results: Our results, based on path analysis, found that three factors, namely satisfaction, attitude of behavior, and subjective norm, positively affected a user’s continued use of Facebook. Perceived ease of use, perceived playfulness, trust, and privacy policy indirectly affected users’ intentions to continue using the website through attitude of behavior. Trust was the strongest determinant of continued use, whereas community switching cost had the weakest effect. Conclusion: Trust had the strongest effect on users’ intentions to continue using Facebook. Our results could serve as useful guidance to website providers for establishing or maintaining social networking sites, including those related to health and hospital information.
