The short food literacy questionnaire (SFLQ) was developed to measure a broad range of skills including functional, interactive, and critical elements of FL. This study evaluated SFLQ measurement properties. We used a workplace intervention trial to reduce salt intake in Switzerland to explore the underlying structure of the questionnaire with 350 respondents and identify the ideal number of SFLQ items to capture the different elements of FL. Exploratory factor analysis showed a unidimensional structure of the final 12-item questionnaire. A sum score based on all 12 items (Cronbach's α = 0.82) showed expected positive associations with health literacy and knowledge of recommended salt intake. The findings indicate the SFLQ is a feasible and reliable tool to assess FL among adults that can be helpful in public health practices focusing on FL.
