Purpose: This study aimed to translate and test the content validity and reliability of an English questionnaire used in the American food and health survey. Methods: The questionnaire was developed using 6 stages, then examined for test–retest. A total of 672 participants were recruited for validation and reliability. Validity test was performed using a correlation coefficient to measures the linear correlation between 2 questions at one given time. Moreover, the Kaiser-Meyer-Olkin, Measure of Sampling Adequacy, and Bartlett’s Test of Sphericity were performed to statistically determine the suitability for conducting exploratory factor analysis. Furthermore, reliability tests using Cronbach α was used to estimate the reliability coefficient properties of the translated scale. Finally, the most important correlated questions was plotted using a color-coded correlogram. Results: The test–retest reliability of all tested items was significantly correlated. The reliability test for all questions was 0.9. The cross-correlation test showed that all questions of the translated questionnaire were correlated significantly ( P < .05) indicating reliability of the questionnaire. Conclusion: The tested questionnaire is applicable and may be used in population-based studies to raise awareness regarding health, food consumption, nutrition, and food safety among people in Jordan and/or other Arab countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
