SDOH Concept Set - Food Insecurity Answer - to Negatively Framed Survey Question - Social Need Not Indicated

We curated SDOH food insecurity survey question and answer concepts into reusable, interoperable OMOP concept sets for use in the OMOP CDM to support standardized data transformation, transparent cohort definitions, and reproducible data extraction. Well-vetted food insecurity survey instruments such as AHC-Tool, Arlington, and WeCare were reviewed to identify questions and mapped to OMOP concepts. SDOH need determination was based on structured evaluation of question–response pairs rather than isolated concepts, with the directionality of both the question and the response playing a critical role. Survey question concepts were categorized as indicating need or no need based on the inferred meaning of the paired question–response pair. The answer concepts in this set represent no social need when paired with negatively framed question concepts. (10.5281/zenodo.18793729)
