Background

Nutritional knowledge assessment is an important component in nutrition research, and a prerequisite for the implementation of many policies and programs aimed at improving eating behavior. In order to generate objective results, validated tools for a given population must be employed. The aim of this study was to determine the validity and reliability of a nutrition knowledge questionnaire for Romanian adults.

Methods

Kleimann’s version of a General Nutrition Knowledge Questionnaire, was translated and adapted to Romanian language, culture, and cuisine. The final format was developed in several steps and used four components: internal and external reliability were assessed in a general population sample (n1 = 412), respectively in a subgroup (n2 = 46) from Component 1; Component 3 assessed construct validity (n3 = 96) using the “known-groups” method; Component 4 (convergent validity, n4 = 508) tested the association between socio-demographic characteristics and nutrition knowledge.

Results

The overall internal reliability was 0.878 and the external reliability was >0.880 in all sections, and overall. Specialists had higher scores than nonspecialists, with a very large effect size. In the general population, females scored higher than males, and middle-aged and older adults scored higher than young adults. Higher scores were associated with higher levels of education. The characteristics of individuals prone to giving wrong answers were: males (beta = 0.170), high school or less (beta = 0.167), and no training in nutrition (beta = 0.154).

Conclusions

The Romanian version of the General Nutrition Knowledge Questionnaire is a reliable and valid tool for measuring nutrition knowledge in adults.

罗马尼亚人口中成年人一般营养知识问卷的信度和效度

背景

营养知识评估是营养研究的重要组成部分，也是实施旨在改善饮食行为的许多政策和计划的前提。为了产生客观结果，必须使用针对给定总体的经过验证的工具。这项研究的目的是确定针对罗马尼亚成年人的营养知识问卷的有效性和可靠性。

方法

克莱曼（Kleimann）撰写的《一般营养知识问卷》已经过翻译，并适应了罗马尼亚的语言，文化和美食。最终格式分几个步骤开发，并使用了四个部分：内部和外部可靠性分别在总体人口样本（n1 = 412）和组件1的一个子组（n2 = 46）中进行评估。组成部分3使用“已知群体”方法评估了结构的有效性（n3 = 96）；组成部分4（收敛效度，n4 = 508）检验了社会人口统计学特征与营养知识之间的关联。

结果

在所有部分以及总体上，整体内部可靠性为0.878，外部可靠性> 0.880。专家的得分比非专家高，且效应量很大。在一般人群中，女性得分高于男性，中老年人则高于年轻人。分数越高，受教育程度越高。容易给出错误答案的个人特征是：男性（β= 0.170），高中或以下（β= 0.167），没有接受过营养培训（β= 0.154）。

结论

罗马尼亚文的《一般营养知识问卷》是一种用于测量成人营养知识的可靠有效工具。
