本研究以嘉義市民管絃樂團暨合唱團之全數及少數曾參與過此樂團團練及演出的團員為研究對象,探討非營利、無償且無給職之非職業音樂社團參與者,其在認真性休閒與心流體驗間之關係,以及情境涉入在兩者間所扮演的中介效果。本研究以文獻探討為基礎,根據文獻提出假設研究,並以(曾)參與嘉義市民管絃樂暨合唱團團練、演出之團員為研究對象,利用問卷調查方式進行研究,共發放160份問卷,收回之有效問卷共計158份,回收率98.8%。接著,本研究將以SPSS (Statistical Product and Service Solutions)為研究工具,建立結構方程模式(SEM)。進一步將情境涉入在認真性休閒與心流體驗間之概念量化,期望藉由此研究,了解樂團參與者認真性休閒與心流體驗間之關係,並進一步了解情境涉入在兩者間所扮演的中介角色。研究結果發現,認真性休閒特質越明顯的樂團參與者,其心流體驗程度越高,且情境涉入之程度也會越明顯。樂團參與者情境涉入的程度愈高,從活動所獲得的心流體驗相對愈強烈。再者,認真性休閒與心流體驗間之關係,經由情境涉入為部分中介效果,能與心流體驗有更顯著的正向關係,其意指樂團參與者的涉入情境愈高時,會增強其心流體驗之效果。本研究最後就結果進行討論,並提出相關之建議,以作為嘉義市民管弦樂暨合唱團亦或其他相關性質樂團日後經營及決策時之參考。 The purposes of the study emphasize on members of Chia-yi Citizen's Orchestra & Chorus, and investigate the relationships among serious leisure and flow experience of their non-profit and amateur participation without consideration. Besides that, we test the mediate effect of situational involvement. This study builds a model and hypothesis according to literatures. Total 160 questionnaires were sent out, and 157 questionnaires were valid, and the rate of return was 98.1%. Structural equation modeling (SEM) is applied to test the cause relations between variables and examine the hypothesis using SPSS (Statistical Product and Service Solutions). Based on the research finding, it represented that serious leisure has positive relationship with flow experience and situational involvement. When the members of orchestra and chorus have higher situational involvement, they have positive influence on flow experience. Furthermore, situational involvement is a mediator between serious leisure and flow experience. Finally, the research put forward suggestions based on the research findings to offer Chia-yi Citizen's Orchestra & Chorus and other similar orchestras reference on manage strategies and policies.
