運動樂趣來源量表(The Inventory of Sourco of Sport Enjoyment)是用以測量運動員參與運動時的樂趣來源。本研究的目的在利用探索性與驗證性因素分析來驗證運動樂趣來源量表的信度與建構效度。第一階段以台中市六所國、高中田徑選手共122人爲對象，進行探索性因素分析考驗量表的信度與效度。結果顯示，量表經由探索性因素分析以後產生與原來相同之四個因素，而四個因素的累積總解釋變異量爲63.88%，各因素的Cronbach's alpha係數介於.84-91。第二階段以台中地區二十所國、高中田徑選手共263位爲對象，同時以上述探索性因素分析的結果，提出一完整的驗證性因素分析的假設模式進行量表之驗證性因素分析。結果顯示，運動樂趣來源量表四個因素之測量模式經修正後其各項配適度指標分別爲χ^2(194)=334.55，p<.05，χ^/df=1.724，GFI=0.90，NFI=0.95，NNFI=0.98，CFI=0.98，RMR=0.042，RMSEA=0.052。由上述各項適合度指標顯示，運動樂趣來源量表具有良好的建構效度，可供研究者針對國、高中田徑選手進行後續相關之研究。

The inventory of source of sport enjoyment was designed to measure the source of enjoyment when athletes involved in sport. The purpose of this study was to test the reliability and construct validity of the inventory of source of sport enjoyment by using the exploratory and confirmatory factor analysis. In the first stage, a total of 122 high school track and field athletes recruited from six schools were served as the subjects. The exploratory factor analysis (EFA) method was used to test the construct validity of the inventory. The results indicated that four factors were emerged just as the original inventory, and the four factors accounted for 63.88% of total explained variance. The Cronbach's alpha coefficient of these four factors ranged from. 836 to. 907. In the second stage, 263 male and female high school track and field athletes recruited from twenty schools in Taichung area were served as participants. The confirmatory factor analysis (CFA) method from LISREL 8.52 statistical package was used to test the hypothetical measurement model. The results indicated that the revised hypothetical four factors of the inventory of source of sport enjoyment fitted the data. The model fit index were showed as follow: χ^2(194)=334.55, p<.05, χ^2/df=1.724, GFI=0.90, NFI=0.95, NNFI=0.98, CFI=0.98, RMR=0.042, RMSEA=0.052. The results from above indicated that the construct validity of the inventory of source of sport enjoyment was acceptable and could be utilized for high school track and field athletes in the future studies.
