「高職學生學業動機調節量表」構念效度驗證之研究

Confirmatory Factor Analysis and Construct Validity of the Academic Motivational Regulation Scale for Taiwan Vocational High School Students

研究旨在發展一份適合國內高職學生學業動機調節量表，以驗證性因素分析及測量恆等性來檢驗。研究對象為中部地區高職二年級學生共1273人。首先，以男生樣本606位評鑑測量模式是否與實徵資料相互適配，並且找出最佳的適配與簡效模式。結果顯示二階因素模式為最佳簡效模式且適配良好，進而檢定此一最佳簡效模式之信效度，包括個別項目信、組成信度、收斂效度以及區別效度。最後，再以女生樣本667位進行測量恆等性檢驗，結果顯示對不同性別的高職學生而言，該量表通過恆等性之檢驗，顯示該量表具有跨樣本的有效性及穩定性。 The purpose of this study was to examine the construct validity of Academic Motivational Regulation Scale by confirmatory factor analysis and to test the factor invariance of this scale. The subjects were 1,273 students, drawn from vocational high schools in central Taiwan, divided into two groups. The first group of 606 male students was used for the development of Academic Motivational Regulation Scale and to conduct confirmatory factor analysis. This study adopted the way of comparing the model fitness of the competitive models to choose the best model. Furthermore, this study tested the reliability and validity of the best model, including item reliability, composite reliability, convergent validity and discriminant validity. At last, the other group (667 female students) was used to measure invariance of the best model to assure the stability of the factorial structure construct validity. The factor structure was a good fit for the empirical data and invariant across gender levels.
