Abstract:	行政院衛生福利部的國民營養調查發現，依照每日3份蔬菜、2份水果的飲食建議，有高達八成的國人蔬果普遍取不足。若每日蔬果攝取量少於600克，則會增加罹患心血管疾病、大腸癌和其他慢性病的風險。本研究以台南某科技大學學生為受試者，樣本數為46位（男性N=24、女性N=22），旨在以質性研究方式探討蔬果攝取的飲食行為改變經驗與社會心理因子間的關係。研究架構以三種社會心理理論為基礎，包括健康信念模式、社會認知學說及計畫行為學說。結果發現，改變蔬果攝取行為與引用於健康信念模式中之自覺障礙與自覺利益（44.4%、33.3%）、於社會認知學說中之技能、社會支持與自我效能（29.9%、25.2%及12.1%）、以及於計畫行為學說中之自覺行為控制（78.6%）做為應用策略或影響因素的頻率較高。顯示這六個因子於蔬果攝取行為上的應用性較大。此結果在未來飲食介入上可提供重要的參考價值，來做為輔助及修正國人蔬果攝取相關的飲食行為。 A nutrition survey conducted by the Department of Health found that, based on the daily dietary recommendations with three servings of vegetables and two servings of fruits, there was up to 80% of the population, regardless of age, with inadequate intake of fruit and vegetable (F&V). If the daily intakes of F&V are less than 600 grams, there is an increased risk of chronic disease, cardiovascular disease and colorectal cancer. The subjects were composed of the students of an University of Technology in Southern Taiwan, with a sample number of 46 (24 male and 22 female). The study aimed to investigate qualitatively the correlation between the psychosocial factors and behavioral strategies used to improve the F&V intake. The research was based on three social psychological theory as framework: the Health Belief Model (HBM), Social Cognitive Theory (SCT), and Theory of Planned Behavior (TPB). It found that the frequencies of application of perceived barriers and perceived benefits from HBM as behavioral strategies for the improvement of F&V intake were 44.4% and 33.3%, respectively; self-efficacy, skills and social support from SCT were 29.9%, 25.2% and 12.1%, respectively; and perceived behavior control from TPB was 78.6%. Those psychosocial factors relative to the behavioral strategies used most frequently implies that they are most applicable in terms of increase of F&V consumption. The study provides important psychosocial correlates of F&V intake, which might help to facilitate the adoption of behavioral changes regarding F&V consumption.
