Abstract

Introduction: food literacy emerges as a subset of health literacy, focusing on individuals' capacity to receive, comprehend, and utilize nutritional information for their dietary choices. This study aims to evaluate the validity and reliability of the Persian version of the short food literacy (SFL) questionnaire for adults. Methods:  The study employed the short Swedish food questionnaire, which underwent a forward and backward translation process, review by experts, proofreading, and finalization. The target language questionnaire was subjected to content validation through Lawshe's content validation ratio (CVR) by presenting it to a panel of 10 nutrition experts. Also, it was evaluated by a team of experts including Persian literature, public health, and nutrition sciences professors. Internal consistency reliability, and descriptive analysis of data were conducted. Results: The final Persian questionnaire comprised 16 questions in three areas of functional, interactive, and critical. The Cronbach's alpha coefficient was 0.7, and the correlation between the areas were statistically significant at an acceptable level. The Intra-class Correlation Coefficient (ICC) for the questionnaire items ranged from 0.61 to 0.85, demonstrating moderate to good reliability. Conclusion:  The Persian version of the SFL questionnaire is a valid and reliable tool for assessing food literacy in adults.
