Analogous to health literacy, food literacy can be defined as a set of cognitive and social skills associated with the ability to acquire and understand information about food and nutrition to make appropriate nutritional decisions. In the literature, several terms such as food, nutrition, or nutritional literacy are used in parallel, differing in some aspects of their meaning. Food literacy is an important measure of the effectiveness of nutritional education interventions and appropriate instruments for its measurement should be available in every society. The aim of this study was the assessment of the validity and testing of a proposed model of the Short Food Literacy Questionnaire (SFLQ) culturally adapted into Polish. The analysis was performed on data from an online survey in a representative sample of 1286 adult internet users. Exploratory (EFA) and confirmatory factor (CFA) analyses were performed on two different subsets obtained through random splitting of the initial dataset. The Polish version of the SFLQ had good internal consistency (Cronbach's α 0.841; Guttman split-half coefficient was 0.812). The EFA revealed that the tool had a three-factor latent structure. The distinguished dimensions were 'information accessing', 'knowledge', and 'information appraisal'. The subscales also showed acceptable internal consistency based on the values of the Cronbach's α coefficients (ranging from 0.768 to 0.845). The CFA confirmed a good fit of the three-factor model with at least five indexes achieving acceptable levels (CFI = 0.972, GFI = 0.963, AGFI = 0.940, NFI = 0.959, and RMSEA = 0.059). The validation of the Polish version of the SFLQ revealed, contrary to earlier reports, not a single but a three-factor structure of the instrument. The SFLQ will be an important tool for the assessment of the effectiveness of educational interventions and population studies analyzing the determinants of food literacy in Poland.
类似于健康素养，食品素养可以被定义为一套认知和社会技能，与获取和理解有关食品和营养信息以做出适当营养决策的能力相关。在文献中，有几个术语如食品、营养或营养素养并行使用，在其含义的某些方面有所不同。食品素养是营养教育干预效果的重要衡量标准，每个社会都应该有适当的测量工具。本研究的目的是评估经文化调整后适用于波兰的短食品素养问卷（SFLQ）的有效性和测试该模型。分析是基于在代表性的 1286 名成年互联网用户的在线调查数据进行的。通过对初始数据集的随机分割，对两个不同子集进行了探索性（EFA）和验证性因素（CFA）分析。SFLQ 的波兰语版本具有良好的内部一致性（Cronbach's α 为 0.841；Guttman 分割半系数为 0.812）。EFA 表明该工具具有三因素潜在结构。区分的维度是“信息获取”、“知识”和“信息评估”。根据 Cronbach's α 系数的值，子量表也显示出可接受的内部一致性（范围从 0.768 到 0.845）。CFA 证实了三因素模型具有良好的拟合度，至少有五个指标达到了可接受的水平（CFI = 0.972，GFI = 0.963，AGFI = 0.940，NFI = 0.959，和 RMSEA = 0.059）。SFLQ 波兰语版本的验证结果表明，与之前的报告相反，该工具不是单一的，而是具有三因素结构。SFLQ 将是评估教育干预效果和分析波兰食品素养决定因素的人群研究的重要工具。
