本研究旨在針對國中小體育教師編製一份具有信效度之「休閒動機量表」，並比較不同背景的體育教師在此工具上是否具有組間不變性。研究者透過分層隨機與叢集取樣共獲得878份有效樣本，並將此樣本隨機分為二等分。先以第一組樣本作項目分析、驗證性因素分析和多群組分析，然後再用第二組樣本進行複核效化研究。結果發現，本量表題目非常適切，且蒐集的資料適配本研究所提出之理論模式，顯示此模式具有穩定與預測性。因此，本研究的量表是一份具有信效度的量表，且體育教師的「任教階段」及「畢業科系」變項在該量表上均具有組間不變性，但「性別」與「任教地點」變項僅具有部分之測量不變性，主要差異則分別源於「勝任熟練性」和「智力性」構面題目之影響。

In this study, a reliable and valid leisure motivation scale was constructed for physical education teachers in Taiwanese junior high and elementary schools. The developed scale was evaluated for invariances in the background variables of physical education teachers. In total, 878 valid samples were collected through stratified random sampling and cluster sampling. The samples were randomly divided into two sets. The first sample set was examined through item analysis, confirmatory factor analysis, and multigroup analysis. The second sample set was tested through cross-validation. The results indicated that the items of the developed scale are appropriate, and the collected data fit the developed theoretical model, which indicated that this model is stable and predictable. Therefore, the proposed scale is reliable and valid. Invariance was identified in two variables: teaching stage and graduation department. The partial invariance in gender and teaching location is related to competence mastery and intellectual categories, respectively.
