INTRODUCTION : Nutrition literacy in Indonesia among adulth is still vague. The previous research suggested a Short Food Literacy Questionnaire (SFLQ) to assess nutrition literacy. The SFLQ original version has not yet been translated into and has not yet been used in Indonesia. The validation and reliability testing of SFLQ among Indonesian adults is essential for assessing their food and nutrition literacy accurately and effectively. This step is important for assessing the tool whether it is valid and reliable in measuring knowledge, skills, and behaviors related to food and nutrition to ensure the Good Health and Well Beings in the future. Through detailed validation, the SFLQ becomes a dependable method for conducting research, assessing diets, and creating nutritional programs aimed at increasing food and nutrition understanding among Indonesian adults. OBJECTIVES : We aimed to test the validity and reliability of the Short Food Literacy Questionnaire (SFLQ) instrument in Indonesian Adults. METHODS : The present study was used a cross-sectional study using an online survey that conducted between in the first week of March 2024 with 121 participants from Sidoarjo, Surabaya, and Malang of East Java, Indonesia. We used STATA 17 to analyze the validity and internal consistency (Cronbach's alpha). The Short Food Literacy Questionnaire (SLFQ) consists of 12 questions with a specific question, in the fifth question, about particular nutrients, such as protein or carbohydrate, fat, and salt recommendation. RESULTS : The average interitem correlation for questionnaire validation showed values of 12 questions lower than 0.05 which is indicating a strong validity. Moreover, a Cronbach's alpha of 12-item with focus on sugar-salt-fat in the fifth question was 0.877. Meanwhile, a Cronbach's alpha of 12-item with focus on protein in the fifth question was 0.884, means the SLFQ is a reliable and valid to be used among Indonesian adults. CONCLUSION : The study affirmed the Short Food Literacy Questionnaire (SFLQ) as both a reliable and valid measure for evaluating food and nutrition literacy in Indonesian adults, ensuring its accuracy for this specific demographic.
