本研究目的在於應用計畫行為理論模式，探究高職輕度智能障礙學生從事休閒活動之意圖。本研究著重探討高職智能障礙學生心智障礙之特殊性對從事休閒運動之影響，並以高、低運動參與程度組作為中介探討對行為意圖之干擾作用。本研究採調查法以中部地區5所學校之高職綜合職能科學生為研究樣本進行叢集抽樣，有效樣本共300位。問卷資料以AMOS19.0進行SEM結構方程式檢驗後，研究結果發現：高職輕度智能障礙學生之行為態度對行為意圖不會產生正向影響情形。高主觀規範與知覺行為控制會對行為意圖產生正向影響情形，其中，以知覺行為控制影響情形表現最高。行為態度、主觀規範與知覺行為控制三者之間具有正向的相關情形。本研究更進一步分析發現高、低不同運動參與程度組在主觀規範及知覺行為控制對行為意圖關係中具干擾作用。最後針對本研究結果提出相關建議，以作為日後相關單位推廣身心障礙學生參與休閒運動之政策參考。

The purpose of this study is to use the planned behavior theory model to explore the intention of students with intellectual disabilities in vocational schools to engage in leisure activities. This study focuses on the influence of the specificity of the mental disabilities of students with intellectual disabilities in vocational schools on leisure sports, and explores the interference effects on behavioral intentions with high and low levels of participation in sports. This research adopts a cluster sampling method for five vocational schools of intellectual disabilities students . There are a total of 300 valid samples. Questionnaire data ASEM19.0 SEM structure equation test, the study found that: Higher vocational students with mild mental disabilities behavioral intentions do not have a positive impact on the attitude. High subjective norms and perceptual behavior control have a positive impact on behavioral intentions, of which, perceived behavioral control has the highest performance. There is a positive correlation between behavioral attitude, subjective norms, and perceptual behavior control. This study further analyzed that high and low levels of participation in the exercise group interfered with the relationship between subjective norms and perceived behavioral control and behavioral intentions. Finally, relevant recommendations are made for the results of this study to serve as a policy reference for future students to participate in leisure sports.
