本研究，旨在檢驗參與羽球不同運動階段學生的知覺有用性、知覺易用性、行爲態度與行爲意圖差異，可助於瞭解個體行爲的改變機制。本研究，採立意抽樣方式，選取中部6所大專校院之學生作爲研究對象，經問卷調查分析後，有效問卷爲517份。經SPSS統計軟體之單因子變異數分析檢定，結果發現：不同羽球運動改變階段的學生在知覺易用性構面，以維持期＞行動期、準備期、意圖期、無意圖期。在知覺有用性構面，以維持期＞行動期、準備期、意圖期、無意圖期。在行爲態度構面，以維持期學生高於行動期學生、準備期學生、意圖期學生、無意圖期學生，且意圖期學生＞無意圖期學生。在行爲意圖構面，以維持期＞行動期、準備期、意圖期、無意圖期。最後依據研究發現提出學理支持與相關應用，並對未來研究方向提出建議。

This research aimed to examine the distinction among perceived usefulness, Perceived Ease of Use, Behavior Attitude and Behavior Intention for students taking involvement in various badminton exercise stages. It was helpful to understand change mechanisms of individual behaviors. This research was implemented with purposive sampling and there were experimental subjects selected from 6 universities in the middle regions of Taiwan. After questionnaire survey was done, there were 517 replies received. With ANOVA analysis through SPSS, research results were indicated as below. About the dimension of perceived ease of use for students under various badminton exercise change stages, it appeared Maintenance Stage was more significant than Action Stage, Preparation Stage, Contemplation Stage and Precontemplation Stage. For the dimension of perceived usefulness, it appeared Maintenance Stage was more significant than Action Stage, Preparation Stage, Contemplation Stage and Precontemplation Stage. For the dimension of behavior attitude, students under the Maintenance Stage showed more significant trend than those under Action Stage, Preparation Stage, Preparation Stage and Precontemplation Stage. In addition, students under Contemplation Stage showed more significant trend than those under Precontemplation Stage. For the dimension of behavior Intention, it appeared Maintenance Stage was more significant than Action Stage, Preparation Stage, Contemplation Stage and Precontemplation Stage. Finally, based on research results, there were theories and suggestions for upcoming research effort proposed.
