In order to face food insecurity as a global phenomenon, it is essential to rely on
measurement tools that guarantee comparability across countries. Although the official
indicators adopted by the United Nations in the context of the Sustainable Development
Goals (SDGs) and based on the Food Insecurity Experience Scale (FIES) already embeds
cross-country comparability, other experiential scales of food insecurity currently employ
national thresholds and issues of comparability thus arise. In this work we address
comparability of food insecurity experience-based scales by presenting two different
studies. The first one involves the FIES and three national scales (ELCSA, EMSA
and EBIA) currently included in national surveys in Guatemala, Ecuador, Mexico and
Brazil. The second study concerns the adult and children versions of these national
scales. Different methods from the equating practice of the educational testing field are
explored: classical and based on the Item Response Theory (IRT).
