Measuring Nutrition Literacy in Spanish-Speaking Latinos: An Exploratory Validation Study

This study aimed to adapt the validated Nutrition Literacy Assessment Instrument for Spanish-speaking Latinos. This study was developed in two phases: adaptation and validity testing. Adaptation included translation, expert item content review, and interviews with Spanish speakers. For validity testing, 51 participants completed the Short Assessment of Health Literacy-Spanish (SAHL-S), the Nutrition Literacy Assessment Instrument in Spanish (NLit-S), and socio-demographic questionnaire. Validity and reliability statistics were analyzed. Content validity was confirmed with a Scale Content Validity Index of 0.96. Validity testing demonstrated NLit-S scores were strongly correlated with SAHL-S scores (r  = 0.52, p <  0.001). Entire reliability was substantial at 0.994 (CI 0.992–0.996) and internal consistency was excellent (Cronbach’s α = 0.92). The NLit-S demonstrates validity and reliability for measuring nutrition literacy among Spanish-speakers.
