摘要

目標：探討長期的社會網絡演變與健康行為之間的關係。方法：採取長期貫時追蹤設計，以南部某大學90名新生為研究對象，結構式問卷搜集社會網絡與健康行為的資料，於94學年度上、下二學期收集七次資料；應用SIENA社會網絡分析軟體進行分析。結果：友誼網絡的改變速率漸減，表示友誼的演變漸趨穩定，相互性、傳遞性與改變速率呈現正相關，表示友誼關係的建立是需要互惠的來往，共同的朋友也會增強友誼網絡的形成。運動及吃早餐是影響友誼網絡形成初期重要的健康行為，友誼形成後期，吸菸及飲酒行為才成為顯著的影響因素。結論：健康行為是否合乎社會規範，在友誼發展過程中是重要關鍵，合乎社會規範的健康行為通常是外顯的，且有相同行為者易形成友誼網絡；不合乎社會規範的，則隱而不顯，直至友誼發展的後期，才會顯現出來。

Objectives: This study investigated the relationship of dynamic friendship networks and health behaviors. Methods: Panel data were collected in seven waves at intervals of one academic semester on 90 university freshmen in southern Taiwan with questionnaires. The Simulation Inverstigation for Empirical Network Analysis (SIENA) was applied to analyze the panel data. Results: The decreasing rate of the network evolution indicated that the friendship dynamics slowed down across time. The positive parameter of reciprocity and transitive triplets demonstrated the strong tendency of friendship toward reciprocity of choice and toward transitivity. In the meeting process, healthy behaviors such as taking exercise and eating breakfast were important to determine the changes of friendship networks; while in the later stages, unhealthy behaviors such as smoking and drinking were important determinants. Conclusions: In the process of friendship formation, healthy behaviors were practiced as visible characteristics and had similarity effect on friendship formation. Social norm would keep unhealthy behaviors invisible until later stages.
