Journal of the Faculty of Tourism and Hotels-University of Sadat City, Vol. 5, Issue (1/1), June 2021 173 Introducing a New Egyptian Version of the General Nutrition Knowledge Questionnaire (E-GNKQ) for Adults: Validity and Reliability Test Mohammed Ezzat Hashad Mohammed Aboutaleb Mohammed Faculty of Tourism and Hotels, University of Sadat City, Egypt Abstract The present study aims to introduce a new Egyptian version of the general nutrition knowledge questionnaire (E-GNKQ) for adults by assessing its validity and reliability in an Egyptian context. The study relied on the revised version of the general nutrition knowledge questionnaire, performed by Kliemann et al. in 2016. The questionnaire was translated and adapted into a seventy- eight-item Arabic version. The questionnaire was subjected to five validation studies that were carried out for content validity; face validity; internal reliability and external reliability; construct validity between participants with nutrition knowledge and with little nutrition knowledge, and without nutrition knowledge; and convergent validity for correlation between nutrition knowledge and demographic characteristics. The study targeted two groups of students (students of the Department of Nutrition and Food Science at Menofia University (n 163), and students of the Faculty of Tourism and Hotels at the University of Sadat City (n 91). The seventy-eight-item Egyptian General Nutrition Knowledge Questionnaire had an acceptable construct, content and face validity, internal consistency, test-retest reliability, and convergent validity. So, it has been shown that the E-GNKQ is a valid and reliable way to measure how much college students in Egypt know about nutrition.

The relationship between food and health has received great attention from those interested in nutrition, as proper nutrition based on nutrition knowledge can prevent and treat many illnesses (Peña-Romero et al., 2018). Nutrition knowledge is considered one of the most important factors associated with health awareness, as it has been found that many harmful health problems are associated with a low level of health awareness among individuals. Studies show that people with a low level of health awareness are less likely to deal with chronic diseases, such as obesity (Spronk et al., 2014). Some studies proposed that the deficiency of nutrition knowledge among people may be involved in the higher rates of overweight and obesity among low-income communities (Rose & Bodor, 2006; Townsend, 2006). While raising individuals' nutrition knowledge level may partly decrease the health variation that exists among low-income communities (Townsend, 2006). Individuals' nutritional knowledge is very important. Inconvenient nutrition knowledge is considered a hurdle to fostering healthful behaviors and preserving wellness (Worsley, 2002; Nanayakkara et al., 2018). Based on the integrated theory of Health Behavior Change, modification of health and nutritional behavior can be effectively enhanced through knowledge and beliefs about a certain topic, especially when used in intervention contexts. Therefore, it is assumed that exposing individuals to intervention or knowledge means (i.e., nutrition education)
