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.
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.
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).
The Romanian version of the General Nutrition Knowledge Questionnaire is a reliable and valid tool for measuring nutrition knowledge in adults.
营养知识评估是营养研究的一个重要组成部分，也是实施许多旨在改善饮食行为的政策和计划的前提。为了得出客观的结果，必须使用针对特定人群的经过验证的工具。本研究旨在确定罗马尼亚成年人营养知识问卷的有效性和可靠性。
克莱曼（Kleimann）的一般营养知识问卷版本经过翻译和改编，以适应罗马尼亚的语言、文化和烹饪风格。最终格式分几个步骤制定，使用了四个部分：内部和外部可靠性分别在一般人群样本（n1=412）和第一部分的亚组（n2=46）中进行评估；第三部分使用“已知群体”方法评估结构有效性（n3=96）；第四部分（convergent validity，n4=508）测试了社会人口特征与营养知识之间的关联。
总体内部可靠性为 0.878，所有部分和总体的外部可靠性均>0.880。专业人员的得分高于非专业人员，且具有非常大的效应量。在一般人群中，女性的得分高于男性，中年和老年人群的得分高于年轻人群。较高的分数与较高的教育水平相关。容易给出错误答案的个体特征是：男性（beta=0.170）、高中或以下学历（beta=0.167）以及没有营养培训（beta=0.154）。
罗马尼亚版一般营养知识问卷是一种可靠且有效的工具，可用于测量成年人的营养知识。
