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 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.

The objective of this study was to analyze the psychometric properties of the Social Entrepreneurial Antecedents Scale (SEAS) with male and female university students in Mexico. There were 1,619 students from the University of Guadalajara and the Michoacan University of San Nicolas de Hidalgo who participated in the study. The reliability of SEAS was analyzed with Cronbach's alpha and the validity with confirmatory factor analysis using the maximum likelihood estimation method. Three factorial models of the scale were compared and items were added for its adaptation. The values produced by the factorial analysis show that the adapted Social Entrepreneurial Antecedents Scale presents adequate evidence of validity and reliability for university students in the central-western area of Mexico. It is shown that experience with Social Problems, Empathy, Moral Obligation, Self-Efficacy and Social Support favor the Intention of Social Entrepreneurship. This research provides elements for the identification of profiles of potential social entrepreneurs who can influence the development of populations with emerging economies, involving higher education institutions, government, business and society.

Biotechnology has made remarkable progress in recent years, and caused a revolution in different sciences. It is obvious, that the advance of modern biotechnology will have a great influence on the world. On the other hand, some ethical problems have emerged. The arguments about ethical and social impacts of biotechnology made clear that not only getting basic knowledge about biotechnology and genetic engineering, also ethical and social issues must be thought in the schools, because the level of knowledge and the attitudes of new generation is very important for the society, and for the future of our world. It is obvious, that students should know about modern biotechnologies more. So, in this study it is tried to determine the university students’ knowledge towards biotech-nology. This research is carried out in January, 2008. Sample was made by students of two universities of Lithuania in total 287 respondents. In sample students of biological and non biological programs are selected. Our research was conducted in educational faculties mainly where a strong female bias in Lithuania historically exists, it was impossible to adjust the female to male ratio more accurately. The age of students ranged from 18 to 29 years (M = 20.41 years, SD = 1.45). A 16-item Likert-type Biotech-nology Knowledge Questionnaire (BKQ) was used to examine students’ knowledge in biotechnology. The results have shown that students do not have sufficient knowledge about biotechnology. Knowledge of students in the field of biotechnologies is very weak and inconsistent. Knowledge mismatch to modern achievements of a science in the given area. The answers given to the statements do not differ significantly between the biology students and the students who do not take any biology courses (non-biology programms). This result shows that education at the university level does not focus enough on biotechnology and its implications. In the opinion of researchers university students need to learn more facts and issues related to modern biotechnology. Also we need to find some approaches to improve non-biology students knowledge about biotechnology. Key words: biotechnology, knowledge, university students.

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.

AbstractObjectiveTo outline key statistical considerations and detailed methodologies for the development and evaluation of a valid and reliable nutrition knowledge questionnaire.DesignLiterature on questionnaire development in a range of fields was reviewed and a set of evidence-based guidelines specific to the creation of a nutrition knowledge questionnaire have been developed. The recommendations describe key qualitative methods and statistical considerations, and include relevant examples from previous papers and existing nutrition knowledge questionnaires. Where details have been omitted for the sake of brevity, the reader has been directed to suitable references.ResultsWe recommend an eight-step methodology for nutrition knowledge questionnaire development as follows: (i) definition of the construct and development of a test plan; (ii) generation of the item pool; (iii) choice of the scoring system and response format; (iv) assessment of content validity; (v) assessment of face validity; (vi) purification of the scale using item analysis, including item characteristics, difficulty and discrimination; (vii) evaluation of the scale including its factor structure and internal reliability, or Rasch analysis, including assessment of dimensionality and internal reliability; and (viii) gathering of data to re-examine the questionnaire’s properties, assess temporal stability and confirm construct validity. Several of these methods have previously been overlooked.ConclusionsThe measurement of nutrition knowledge is an important consideration for individuals working in the nutrition field. Improved methods in the development of nutrition knowledge questionnaires, such as the use of factor analysis or Rasch analysis, will enable more confidence in reported measures of nutrition knowledge.
