本研究為瞭解國內博物館志工之休閒內在動機、認真休閒特質與休閒滿意度之關係，選取國內唯一非公立、有國際能見度，且有規模志工組織之世界宗教博物館進行問卷調查。共回收有效問卷164份，有效問卷回收率為98.79%。資料分析方法包含敘述統計、獨立樣本t檢定、ANOVA、Pearson相關分析，以及SEM配適度指標測試等。本研究發現，志工休閒內在動機對認真休閒特質影響程度最高，認真休閒特質對休閒滿意度影響次之，休閒內在動機對休閒滿意度影響較小。志工參與頻次在休閒內在動機上有顯著差異，亦會影響認真休閒特質與休閒滿意度。因此建議管理單位應瞭解志工的休閒之內在動機與認真休閒之特質，進而提高其休閒滿意度，以增強其留任意願，並吸引更多志工投入。

The frequency of volunteers’ participation has obvious differences on their intrinsic leisure motivation. At the same time, it influences the serious leisure traits and the leisure satisfaction of volunteers. It is recommended that the management staff of the Museum of World religions should pay more attention to the intrinsic leisure motivation and serious leisure traits of volunteers; in turn, the leisure satisfaction of the volunteers could be increased while sustaining the in-house volunteers at the same time. Various leisure activities for volunteers should be further implemented so as to increase the leisure satisfaction and the willingness of volunteers to stay. As a result, more volunteers are likely to join such services in the Museum of World religions.
