本研究採用社會資本理論來探討群體社會資本建立對於民眾揭露個人健康資訊行為的影響。本研究採用實驗設計法，以大學學生及一般民眾為研究對象，共招募150人，隨機分派參與者至大群體(共15組，每組7人)或小群體(共15組，每組3人)之中。參與者必須針對所提供任務情境，利用即時通訊工具（Line）與組內成員進行為期四週的群組討論，而後參與者填寫問卷。資料分析結果顯示，信任對於民眾揭露個人健康資訊的數量有顯著影響；認同對於民眾揭露個人健康資訊的深度有顯著影響；義務對於民眾揭露個人健康資訊的數量、深度及廣度皆有顯著影響。最後，本研究針對實務面與學術面提出具體建議與未來研究方向。

This study applies social capital theory to investigate the influence of the establishment of social capital on individuals’ health information disclosure behavior. An experimental method was used in this study. Participants were randomly allocated to groups, including 15 large groups (7 participants per group) and 15 small groups (3 participants per group). Each group was required to complete a task situation we provided. The experiments lasted for four weeks. This study recruited college students and the general public to participate in the experiment. A total of 150 people participated in the experiment and filled out the questionnaire. The findings showed that trust significantly affects the extent of personal health information disclosed by individuals. Identification has a significant impact on the depth of personal health information shared, while obligation influences the quantity, depth, and breadth of personal health information disclosed by individuals. Finally, this study proposes specific recommendations and suggests future research directions in both practical and academic aspects.
