Підсумок	The Food Insecurity Experience Scale (FIES) is an experience-based metric of food insecurity built on eight yes/no survey questions and calibrated with a Rasch (one-parameter logistic) item response model. Developed by FAO's Voices of the Hungry project and formalized by Cafiero, Viviani and Nord in 2018, the FIES treats food insecurity as a single latent trait that ranges from anxiety about access, through compromises in food quality and quantity, to going without eating for a whole day. Because the items are calibrated to a common metric and equated onto a global reference scale, the FIES allows comparable estimates of the prevalence of moderate and severe food insecurity across countries and over time, and it is the official instrument used to monitor SDG indicator 2.1.2.	The U.S. Household Food Security Survey Module (HFSSM) is the standard instrument for measuring food insecurity in the United States, developed in the 1990s by the USDA-led Federal Interagency Food Security Measurement Project and documented in Bickel, Nord, Price, Hamilton and Cook's 2000 Guide to Measuring Household Food Security. It is an experience-based scale: a set of ten adult-referenced and eight child-referenced questions, with frequency follow-ups, that ask whether households cut back on food, skipped meals, or went hungry because they lacked money for food. Responses are calibrated with a Rasch measurement model onto a single severity continuum, and households are classified into high, marginal, low, and very low food security, the categories behind the annual national food-security statistics.
