Food literacy is a multidimensional construct required to achieve diet quality. The Food Sensations for Adults (FSA) program aims to improve the food literacy of low to middle-income adults living in Western Australia and is funded by the Western Australian Department of Health. The original published behavior checklist used to measure change in food literacy has been revised based on experience of the facilitators and the iterative development of the program. This research sought to assess the validity and reliability of the improved food literacy behavior checklist. A total of 1,359 participants completed the checklist over an 18-month period. Content, face, and construct validity were considered in the re-development of the checklist. An exploratory factor analysis of the checklist identified three factors: (1) Plan and Manage, (2) Selection, and (3) Preparation. Cronbach's alpha coefficients of 0.883, 0.760, and 0.868 were found for each of the three factors respectively. These coefficients indicated good internal consistency and were higher than those found in the original checklist analysis. An external validation was undertaken with the original food literacy behavior checklist, and a strong positive relationship between the two tools was found. In addition to being used to evaluate FSA, this revised and extensively validated tool could provide guidance to others evaluating similar food literacy programs and contribute to international measurement research.
食品素养是实现饮食质量所必需的多维结构。成人食品感官（FSA）计划旨在提高生活在西澳大利亚州的中低收入成年人的食品素养，由西澳大利亚州卫生部资助。用于衡量食品素养变化的原始发布行为清单已根据促进者的经验和计划的迭代开发进行了修订。这项研究旨在评估改进后的食品素养行为清单的有效性和可靠性。共有 1359 名参与者在 18 个月的时间内完成了清单。在重新开发清单时考虑了内容、表面和结构有效性。清单的探索性因素分析确定了三个因素：（1）计划和管理，（2）选择和（3）准备。三个因素的克朗巴赫α系数分别为 0.883、0.760 和 0.868。这些系数表明内部一致性良好，高于原始清单分析中发现的系数。对原始食品素养行为清单进行了外部验证，发现这两个工具之间存在很强的正相关关系。除了用于评估 FSA 外，这个经过修订和广泛验证的工具还可以为评估类似食品素养计划的其他人提供指导，并为国际测量研究做出贡献。
