在現今資訊科技發達的社會，人與人之間的相處似乎日趨疏離，但仍有一批默默發心行善的義工在為我們社會無私的付出。他們願意犧牲自己的時間、體力、金錢等投入奉獻，不求回報的服務精神與風範值得讚揚。本研究旨在探討佛光山本山及佛陀紀念館義工之社會支持、工作價值觀與參與動機對工作滿意的影響，並以人格特質為調節變數探討對參與動機與工作滿意之影響。本研究採問卷調查法蒐集資料，共獲得有效問卷347份，並以結構方程模式（SEM）進行資料分析。研究結果發現：義工社會支持與工作價值觀對參與動機有正向影響；義工工作價值觀與參與動機對工作滿意有正向影響。此外，義工工作價值觀會透過參與動機之中介效果影響工作滿意。在調節變數方面，經由內外控傾向人格特質之巢型（Nested）關係模式分析，發現在義工參與動機對工作滿意的關係上，人格特質具有調節效果，且內控傾向人格特質的調節效果大於外控傾向人格特質。

This study mainly intended to explore the effect of volunteers’ social support, job values and participation motivation on job satisfaction, and adopted personality traits as a manipulating variable to explore the effect on participation motivation and job satisfaction. This study employed questionnaire survey method to collect data, and obtained 347 valid copies, and carried out data analysis by using the structural equation modeling (SEM). Research results discovered: volunteers’ social support and job values possessed positive effect on participation motivation, volunteers’ job values and participation motivation had positive effect on job satisfaction, and volunteers’ job values would affect job satisfaction by means of the mediation effect of participation motivation. On the other hand, we discovered that personality traits possessed manipulating effectiveness on the correlation between volunteers’ participation motivation and job satisfaction; moreover, the manipulating effectiveness of internal locus of control personality traits is better than external locus of control personality traits.
