本研究主要探討組織成員有無從事社會志工的經驗，對個人主觀幸福感及人際公民 行為之影響關係，並進一步分析職家衝突對上述關係的調節效果。分析224 份回收有效 問卷獲得以下發現：首先，有志工經驗的組織成員，其個人主觀幸福感與人際公民行為 均高於無志工經驗者；其次，組織成員的職家衝突僅對個人主觀幸福感呈現負向影響； 第三，在調節效果上，職家衝突僅對人際公民行為呈現影響，低職家衝突的組織成員相 較於高職家衝突者而言，其志工經驗能更明顯提高人際公民行為。最後，本文根據研究 發現提出管理上的貢獻以及對實務上的意涵。

The purposes of this study are to analyze the relationships among institutional employees’ experience of volunteership, their subjective well-being and interpersonal citizenship behavior, and further to explore the influence and moderating effect of work-family conflict. We analyzed 224 valid questionnaires and obtained the following findings: firstly, the volunteership experiences help employees to increase their subjective well-being as well as interpersonal citizenship behavior than non-volunteers; secondly, employees’ work-family conflict and subjective well-being has a negative relation; and thirdly, as for the moderating effect, employees with lower work-family conflict exhibit a higher interpersonal citizenship behavior than the employees with higher work-family conflict. Finally, we provide both theoretical contributions and practical implications based on the research findings.
