在時間壓力之下，台灣醫護人員經常沒有足夠時間對病患進行完整衛生教育。少數醫療院所開始嘗試運用聊天機器人解決上述問題，然而民眾是否能夠接受此科技或哪些因素會影響其使用意願仍不清楚。因此本研究以衛教諮詢為例，基於計畫行為理論（Theory of Planned Behavior）探討聊天機器人使用意願。配合問卷調查，共分析 120 份有效問卷。研究結果顯示資訊性、時尚性、使用者涉入會影響態度，使用者涉入會影響主觀規範，態度、主觀規範和認知行為控制會影響意圖。本研究結果可提供醫療機構開發聊天機器人時作參考。;Busy healthcare professionals often do not have enough time to provide their patients with comprehensive health education. As a solution, a small number of organizations have attempted to use chatbots to relay this information. Whether patients can accept this new technology, and what factors influence their willingness to engage with it, are still unclear. Using the theory of planned behavior, uses and gratification theory and involvement theory, this study explored the factors influencing the use of chatbots for health education. We conducted a questionnaire survey that generated 120 valid responses. Results showed that information, fashion and user involvement all significantly influence user attitudes. User involvement significantly influence subjective norms. Attitude, subjective norm and perceived behavior control have a significantly positive impact on intention. The results of this research can serve as reference for healthcare organizations in designing chatbots.
