Abstract
本研究為瞭解國中學生自備餐具之行為意圖及其影響因素，以北縣某國中385位國中生為樣本，針對外食時自備餐具之行為意圖及其相關問題，進行問卷調查，回收有效問卷358 份，回收率為98.62﹪。結果發現，態度、主觀規範、自我效能對行為意圖皆有顯著正面影響，並可解釋與預測行為意圖，其中以自我效能的預測力最佳，主觀規範次之，態度再次之。在個人基本背景外在變項中，只有自備餐具經驗，能直接影響自備餐具意圖。本研究支持理性行動理論中：學生本身從事某行為之態度與主觀規範是影響行為意圖的兩大因素，而且本研究也支持除了態度與主觀規範之外再加入自我效能，可提高解釋力，從原本的30%增加到40.9%，顯著增加了10.9%。
The purpose of this study were to understand the behavioral intentions, and to explore its influencing factors of self-prepared tableware for junior high students of one school at Taipei county. By using a stratified random sampling method, a sample of 385 students were chosen for collecting data by the questionnaire. Among the sample, 358 students provided valid data, response rate being 98.62%. The results of the study were summarized as follows: There were positive influences of attitude, self-efficacy, and subjective norm on behavioral intentions, and could significantly explain the variance of behavioral intentions. Among attitude, self-efficacy, and subjective norm, self-efficacy was the most explanation power toward behavioral intentions, then being subjective norm and attitude. Of the external variables of personal backgrounds, only the experience of self-prepared tableware could directly influence on the behavioral intentions of self-prepared tableware. The results supported the Theory of Reasoned Action with self-efficacy. Both attitude, and subjective norm could explain 30% variance of the behavioral intentions, and self-efficacy could also explain 10.9% variance of the behavioral intentions.
