Abstract

Background: Nutrition literacy (NL) encompasses knowledge and skills that can influence individuals' food choices. The present study aimed to translate and evaluate the psychometric properties of the Persian version of a novel short-form nutrition literacy (NL-SF12 (measurement tool for nursing students. Methods: This study aimed to translate a novel short-form nutrition literacy measurement tool for nursing students into Persian. Subsequently, this version was used for psychometric evaluation. Face, content, and construct validity were assessed using confirmatory factor analysis. Internal consistency (Cronbach's alpha) and test-retest reliability (ICC) were calculated. Data were analyzed using SPSS and AMOS software. Results: The results showed that NL-SF12 was successfully adapted into the Persian language, demonstrating face validity, content validity, convergent validity, and internal consistency for both the overall scale and its subscales. Confirmatory factor analysis indicated that the six-factor conceptual structure of the measure had a good fit. Reliability was assessed using internal consistency and test-retest stability. The Cronbach's alpha coefficient was 0.834 and the infraclass correlation coefficient (ICC) was 0.830. Conclusion: The Persian version of the SF-12 questionnaire is a reliable and valid tool for measuring the health status. Therefore, it can be used for comprehensive assessment of the health status in nursing students.
