Adaptation and Validation of a Nutrition Literacy Assessment Instrument

描述（申请人提供）：2004年，医学研究所引起了全国对健康素养问题的关注，但营养素养却很少受到关注。考虑到美国超重和肥胖以及与饮食有关的慢性病的发病率不断上升，对公众进行营养教育是一项必要的预防措施。由于营养对于预防和治疗许多疾病非常重要，因此卫生专业人员需要能够在确定护理计划之前评估患者对饮食相关信息和技能的能力。虽然我们在初级保健环境中可以使用工具来确定健康素养，但这些工具并不能充分评估营养素养。本研究应用的目标是产生一个有效的工具，用于测量初级保健慢性病患者的营养素养，并确定在何种程度上营养素养与饮食质量。我们假设，营养素养将有很大的不同患者，将与饮食质量。这项研究的长期目标是改善营养教育，作为改善饮食质量的一种手段。本研究申请的具体目标是（目标1）调整营养素养评估工具（NLAI）（我们设计的用于测量营养知识的工具）用于初级保健人群;（目标2）估计NLAI产生一致分数的能力（可靠性），并估计其在衡量营养素养方面的准确性（有效性）;（目的3）评估NLAI预测饮食质量的能力（预测有效性）。我们预计，这些目标将产生一个有效的工具来衡量营养素养，可以广泛应用于医疗保健和研究环境。

DESCRIPTION (provided by applicant): In 2004, the Institute of Medicine brought national attention to the issue of health literacy, but nutrition literacy has received little attention. Nurition education for the public is a necessary preventive measure, considering the increasing rates of overweight and obesity in the United States as well as diet-related chronic diseases. Because nutrition is so important for prevention and treatment of many diseases, health professionals need to be able to assess their patients' competency with diet-related information and skills before determining their plan of care. While tools to identify health literacy are available for us in primary care settings, these tools do not adequately assess nutrition literacy. The objectives of this research application are to produce an effective tool for measuring nutrition literacy among primary care patients with chronic illness, and to identify the extent to which nutrition literacy is associated with diet quality. We hypothesize that nutrition literacy will vary substantially among patients and will be related to dietary quality. The long-term goal of this research is to improve nutrition education as a means for improving diet quality. Specific aims of this research application seek to (Aim 1) adapt the Nutrition Literacy Assessment Instrument (NLAI) (a tool we have designed for measuring nutrition literacy) for use in a primary care population; (Aim 2) estimate the NLAI's ability to produce consistent scores (reliability) and estimate its accuracy in measuring nutrition literacy (validity); and (Aim 3) estimate the ability f the NLAI to predict diet quality (predictive validity). We anticipate that these aims will produce n effective tool for measuring nutrition literacy that can have wide application in health care and research settings.
