The purpose of this research was to investigate how university students' nutrition beliefs influence their health behavioral intention. This study used an online survey engine (Qulatrics.com) to collect data from college students. Out of 253 questionnaires collected, 251 questionnaires (99.2%) were used for the statistical analysis. Confirmatory Factor Analysis (CFA) revealed that six dimensions, "Nutrition Confidence," "Susceptibility," "Severity," "Barrier," "Benefit," "Behavioral Intention to Eat Healthy Food," and "Behavioral Intention to do Physical Activity," had construct validity; Cronbach's alpha coefficient and composite reliabilities were tested for item reliability. The results validate that objective nutrition knowledge was a good predictor of college students' nutrition confidence. The results also clearly showed that two direct measures were significant predictors of behavioral intentions as hypothesized. Perceived benefit of eating healthy food and perceived barrier for eat healthy food to had significant effects on Behavioral Intentions and was a valid measurement to use to determine Behavioral Intentions. These findings can enhance the extant literature on the universal applicability of the model and serve as useful references for further investigations of the validity of the model within other health care or foodservice settings and for other health behavioral categories.
本研究旨在探讨大学生的营养信念如何影响其健康行为意向。本研究采用在线调查引擎（Qulatrics.com）从大学生中收集数据。在收集的 253 份问卷中，有 251 份（99.2%）用于统计分析。验证性因子分析（CFA）表明，六个维度，“营养信心”、“易感性”、“严重性”、“障碍”、“益处”、“健康饮食行为意向”和“进行体育活动的行为意向”具有构念效度；对项目可靠性进行了克朗巴赫α系数和综合可靠性测试。结果验证了客观营养知识是大学生营养信心的良好预测指标。结果还清楚地表明，两个直接测量指标是行为意向的显著预测指标，这与假设一致。健康饮食的感知益处和健康饮食的感知障碍对行为意向有显著影响，是衡量行为意向的有效方法。这些发现可以增强模型在普遍适用性方面的现有文献，并为在其他医疗保健或餐饮环境以及其他健康行为类别中进一步研究模型的有效性提供有用的参考。
