某醫校護理科學生每日吃早餐意圖之研究

Abstract

摘 要 本研究以理性行為理論及自我效能理論為研究架構，目的在探討護理科學生每日吃早餐的意圖，同時瞭解理性行為理論與自我效能應用在每日吃早餐意圖的適切性。 本研究以桃園縣新生醫校護理科一、二、三年級全體學生為母群體並以簡單隨機抽樣方式抽出調查樣本共為638人。研究者依據開放式引導問卷填答結果篩選出顯著信念，擬定成結構式問卷以供集體施測。結構式問卷共得634份有效問卷。 本研究結果如下 一、本研究對象每日吃早餐之意圖，有意圖者為（81.6％）無意圖者為（15％）。 二、本研究對象每日吃早餐的意圖可由態度、主觀規範及自我效能來預測，此三變項共可解釋意圖34％的變異量，其中以自我效能影響最大，態度次之。 三、態度與行為信念、結果評價的交乘積呈現中等程度的正相關（r=.538）；主觀規範與規範信念、依從動機二者的交乘積和呈現正相關（r=.231)。 四、有/無意圖者在行為信念、結果評價、依從動機及自我效能上有整體性差異存在，可提供日後提升每日吃早餐時的教育介入重點。 五、將理性行為理論及自我效能應用在預測每日吃早餐行為意圖時，其結果是支持理論的假設，且是合宜的，但仍須致力於探討如何提升解釋力。

The Research on the Intentions of eating daily breakfast - Nursing School Students as an example Abstract The purpose of this study was to predict and to explain students’ intention in eating daily breakfast on the basis of the theory of Reasoned Action and Self-efficacy theory. The surveyed subjects were students from Tao-yuan Thinshin Nursing School of the first, the second, and the third grade. By stratified cluster sampling method, 638 respondents (94% response rate) were selected to participate in this study. The open-questionnaires and the structured questionnaires were used to collect data. The main findings of this study were: (1) The majority of students (81.6%) did have intention in eating daily breakfast and 15% exhibited no intention at all. (2) The intentions of eating daily breakfast could be predicted by attitude, subjective norm, and self-efficacy. The explained variance was 34%. Self-efficacy appears to be the most influential factor; attitude is the second one. (3) Attitude was found to be significantly positive correlated with the sum of product with behavioral beliefs and outcome evaluation. And the subjective norm was found to be significantly positive correlated with the sum of product with normative beliefs and motivation to comply. (4) Whether there were intentions to eat breakfast or not was shown to differ significantly on behavioral belief, evaluation, normative belief, motivation to comply, and self-efficacy. (5) When the theory of Reasoned Action and Self-efficacy theory are applied to predict the daily breakfast behavioral intentions, the result of this study supports the research assumptions of theories
