AbstractObjective:The aim of this study was to assess the validity and reliability of a self-administered nutrition knowledge (NK) questionnaire for Italian university students.Design:The NK questionnaire included ninety questions on experts’ nutritional recommendations, nutritional content of food, health aspects of food and diets, relationship between diet and diseases, and proper food choices. It was administered to the same population under the same conditions on two different occasions with a time interval of 3 weeks between the two administrations.Setting:The survey was carried out at the University of Parma (Italy) during the 2018–2019 academic year.Participants:Data were collected for 132 bachelor and master degree students attending the University of Parma, either attending or not nutrition classes during their studies (19–30 years, 29·5 % males, 57·6 % with an academic nutrition background).Results:The questionnaire revealed high overall internal consistency reliability (Cronbach’s α > 0·8) and a good temporal stability with high correlation of the total score (r = 0·835, P < 0·001). Moreover, it showed a good ability to discriminate between subjects with potentially different NK.Conclusions:This NK questionnaire proved to be a reliable, valid and easy-to-use tool for assessing the NK of Italian university students, either with or without nutrition background.

Abstract Objectives In this cross-sectional study among 220 medical students we aimed to determine the nutritional knowledge and attitude of medical students through clinical training courses (externship and internship) of Tabriz University of Medical Sciences, Iran. A nutritional knowledge questionnaire included 51 questions was used to determine the correct, perceived and accuracy of knowledge of the participant in different aspects of nutrition sciences. The nutrition attitude questionnaire included 30 questions. Both questionnaires were confirmed in terms of the validity and reliability for assessing nutritional knowledge and attitude in this sample of Iranian medical students. Nutritional knowledge and attitude were calculated as percentage of correct or appropriate responses. Results The correct knowledge was not significantly different among externs and interns (68.20 ± 7.50% and 67.87 ± 6.04% respectively, p = 0.729). Results showed that most of the participants (49.61% of externs and 57.14% of inters) had a poor nutritional knowledge, significantly varied by age (p = 0.035). The attitude index of the subjects was not significantly different among externs and interns (73.36 ± 9.42% and 74.59 ± 9.20%, p = 0.335). Most students (92.7%) had a very appropriate attitude toward nutrition, significantly varied by sex (p = 0.010). These findings indicate that there are multiple deficiencies in nutrition knowledge of medical students.

Abstract 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.

Abstract Objectives To assess validity and reliability of a nutrition knowledge questionnaire originally developed for adults when used with high-school aged adolescents. Methods The nutrition knowledge questionnaire utilized in this study was originally developed for adults and was shown to have content and construct validity as well as internal consistency and test-retest reliability. Two sections of the adult questionnaire, 50 questions total, were administered to adolescents at four high schools: three in California and one in Hawaii. Participants were convenience samples selected by teachers at each school based on known previous nutrition education (n = 174) or no known previous nutrition education (n = 136). Adolescents self-reported their current age and received a $10 gift card for completing the questionnaire. Questionnaire data were assessed for item difficulty, item discrimination with item-total correlation, and construct validity using an independent samples t-test. The overall questionnaire and individual sections were assessed for internal consistency reliability with Cronbach's alpha. Given the difference in nutrition education offered at each site, a post-hoc regression analysis was conducted to assess % correct by group when controlling for school. Results Assessment of item difficulty showed that one question exceeded the suggested 80% threshold, however this question was retained due to acceptable item discrimination. One question was found to negatively correlate with total score and was removed from the questionnaire resulting in 49 questions. The overall questionnaire was shown to have internal consistency reliability (Cronbach's α = 0.83) as were the individual sections (Cronbach's α &gt; 0.70). The questionnaire also demonstrated construct validity with the adolescents that had known previous nutrition education having a significantly higher mean % correct compared to the adolescents without known nutrition education (P &lt; 0.0001). The significant association between groups and % correct remained when controlling for school (P &lt; 0.0001). Conclusions Results suggests that the questionnaire was shown to reliably assess general nutrition knowledge in high school-aged adolescents with validity.
