Abstract
OBJECTIVES: On the basis of an 18-item Household Food Security Scale, a short form was developed to assess financially based food insecurity and hunger in surveys of households with and without children. METHODS: To maximize the probability that households would be correctly classified with respect to food insecurity and hunger, 6 items from the full scale were selected on the basis of April 1995 Current Population Survey data. RESULTS: The short form classified 97.7% of households correctly and underestimated the prevalence of overall food insecurity and of hunger by 0.3 percentage points. CONCLUSIONS: The short form of the Household Food Security Scale is a brief but potentially useful tool for national surveys and some state/local applications.
