在醫療資訊如此發達與便利的同時，也引發許多隱私的問題。因此，本研究以社會認知理論作為基礎，加入隱私與認知評估因素來發展研究架構。本研究旨在探討民眾主動揭露個人健康資料的意圖，會受到哪些因素影響。本研究針對全台半年內具就醫經驗的民眾進行問卷調查，總共回收660份有效問卷，分析結果發現：過去隱私被侵犯經驗，對於個人揭露資料的預期結果與自我效能無顯著影響；行為模仿為影響預期結果的重要因素；行為模仿、健康負面情緒、他人影響、醫療組織隱私保護、法律與政府支持、對系統的信任與揭露資料隱私風險為影響揭露資料自我效能的重要因素；醫療效果認知有用性、預期結果、揭露資料自我效能則是影響個人主動揭露健康資料的重要因素。

While the application of medical information is increasingly well developed, it brings out many privacy issues. Based on social cognition theory, this study includes privacy and cognitive factors to develop a research mode and aims to investigate what factors may influence individuals' intention to disclose medical information. This study conducted a Web survey and 660 usable responses were collected. The analytical results indicate that behavior modeling significantly influences outcome expectations. Behavior modeling, negative emotion of health status, personal influence, privacy policies, legal and government support, trust, and privacy risk significantly influence disclosure self -efficacy. Perceived usefulness, outcome expectation, and disclosure self-efficacy significantly influence individuals' intention to disclose healthcare information. Finally, implications for academics and practitioners are also provided.
