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.<h4>Methods</h4>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.<h4>Results</h4>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).<h4>Conclusions</h4>The Romanian version of the General Nutrition Knowledge Questionnaire is a reliable and valid tool for measuring nutrition knowledge in adults.European journal of clinical nutrition1576-1584https://www.ebi.ac.uk/biostudies/studies/S-EPMC7606136biostudies-literatureReliability and validity of a General Nutrition Knowledge Questionnaire for adults in a Romanian population.PMC7606136Putnoky SBanu AMMoleriu LCSerban DMSerban CLNiculescu MDfalseReliability and validity of a General Nutrition Knowledge Questionnaire for adults in a Romanian population.<h4>Background</h4>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.
