Introducing a new Egyptian version of the general nutrition knowledge questionnaire (E-GNKQ)‎ for adults : validity and reliability test

Abstract EN

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.
