近年來,志工參與逐漸成為深度休閒領域中一個重要議題。本研究旨在從深度休閒理論角度出發,透過質化研究半結構式深度訪談方式,探討議員服務處志工們的參與動機與所獲得的休閒效益。根據研究結果發現:志工們的初始參與動機裡,「利己」和「利他」因素同等重要,且在服務過程中,兩者會互相強化。志工們的參與經驗,展現深度休閒中的六個特質。其中,以獲得「個人的持續利益」最為關鍵,顯示出自我實現、自我滿足等。對於團體的歸屬感及榮譽感,進而產生情感連結,是議員服務處志工們願意持續投入志願服務工作的重要關鍵因素。對於退休者和女性家管的而言,透過志工服務可以增加社會互動及歸屬感,是向外連結社會網絡的重要管道,避免退縮到社會之外。最後,根據研究結果,進一步對未來之研究提出具體可行的建議。 In recent years, the volunteer participation was gradually form a important issue in the field of serious leisure theory.This research aims to understand and discuss the relationship between serious leisure, participation motivation and the leisure benefits.
