大學生減輕體重意圖之研究

A study on weight reduction intention of college students

本研究以計劃行為理論為依據，驗證其在減重行為上的適切性。以78位體重過重的大學生為研究對象，收集其對減重行為的信念、態度、主觀規範及知覺行為控制等資料。研究發現態度、主觀規範及知覺行為控制能共同預測行為意圖(R=.732)。同時也發現某些減重信念與行為意圖間具有顯著相關，並根據研究結果對體重過重者之減重教育提出建議。

Based on the theory of planned behavior, an extension of Ajzen & Fishbein's theory of reasoned action, was tested in the context of weight reduction behavior. Beliefs, attitudes, subjective norms, perceived behavioral control, and intention regarding weight reduction were obtained from 78 obese college students. As expected, intention were best predicted as a function of attitudes, subjective norms, and perceived behavioral control (R= .732). Subsequent analysis revealed that weight reduction intention was correlated with specific beliefs. Implications for use of this knowledge by associations of health education in developing relevant interventions to enhance weight reduction behavior of obese students were discussed.
