The objective of this preliminary study was to apply the theory of planned behavior to explain dietitians' intentions to promote whole-grain foods. Surveys were mailed to a random national sample of registered dietitians to assess knowledge and attitudinal, normative, and control beliefs regarding intention to promote whole-grain foods, with a 39% return rate (n=776, with 628 usable surveys from those working in direct patient care). About half of the respondents had a master's degree, and 58% had substantial experience in the dietetics field. The theory of planned behavior explained intention to promote whole grains to a moderate extent (df=3, F=74.5, R(2)=0.278, P<.001). Most were positive about the health benefits, and few perceived barriers to promotion. However, many had low levels of knowledge and self-efficacy regarding ability to help clients consume more whole-grain foods. Continuing education for dietitians should use strategies that enhance self-efficacy regarding ability to promote whole-grain foods.
这项初步研究的目的是应用计划行为理论来解释营养师推广全谷物食品的意图。调查问卷被邮寄给全国随机抽取的注册营养师样本，以评估他们对推广全谷物食品意图的知识、态度、规范和控制信念，回复率为39%（n = 776，其中628份调查问卷来自直接参与患者护理工作的人员且可用）。约一半的受访者拥有硕士学位，58%在营养学领域有丰富经验。计划行为理论在一定程度上解释了推广全谷物的意图（自由度 = 3，F = 74.5，决定系数R² = 0.278，P <.001）。大多数人对其健康益处持积极态度，很少有人认为推广存在障碍。然而，许多人在帮助客户食用更多全谷物食品的能力方面知识水平和自我效能较低。营养师的继续教育应采用提高推广全谷物食品能力的自我效能的策略。
