Σύνοψη	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.	The Reduced Coping Strategies Index (rCSI) is a standardized, cross-context food-security indicator distilled from the Coping Strategies Index methodology of Maxwell and Caldwell. Where the full Coping Strategies Index inventories many context-specific coping behaviors with locally derived weights, the reduced version fixes on five consumption-based strategies — eating less-preferred foods, borrowing food, limiting portion size, restricting adults' intake so children can eat, and reducing the number of meals — each with a universal severity weight. Multiplying the number of days in the past week each strategy was used by its weight and summing gives a score from zero to 56. Because the strategies and weights are fixed, the rCSI is comparable across populations and countries, making it a widely used quick gauge of food-access stress.
