Abstract

Background: Any program and policy to prevent chronic diseases associated with dietary factors requires major changes in individuals' diet, knowledge, attitude and, consequently, changes in their dietary choices. The purpose of this study was to determine the factors influencing choice of packaged foods in those visiting Ardabil health centers. Methods: In this study, through a literature review, focused group discussions and interview with expert professors, a questionnaire based on the theory of logical action was designed. The validity of the questionnaire was determined by using methods to evaluate content validity, and face validity with a panel of 15 experts. Cronbach's alpha coefficient was used to determine reliability. Results: The first designed questionnaire consisted of 40 items, but after assessing its validity and reliability, the number of items in the final questionnaire decreased to 36 ones. Eleven items were in the nutritional attitude section, 7 in the subjective normative section, 9 questions in the behavioral intent and 9 questions in the nutritional behavior section. The mean validity score of the final questionnaire was 0.82 and Cronbach's alpha coefficient was 0.79. Conclusion: According to the results of this study, the designed questionnaire has acceptable validity and reliability and can be used to identify factors influencing the choice of packaged foods in the community. Keywords: Validity, Reliability, Questionnaire, Packed Food, Reasoned action theory
