The U.S. Household Food Security Survey Module was translated into Spanish and adapted for use in the Dominican Republic. Qualitative assessment in a focus group was conducted to confirm the relevance of the concepts and to refine the questions. A pilot survey of 110 households in a rural, economically vulnerable community was conducted, and the data were analyzed to assess the validity of the questions as a multiple-item measure of household food insecurity. Both internal and construct validity appear to be acceptable, although further assessment of two items is recommended. The Dominican survey module complements work in several other countries in Central and South American and the Caribbean to develop a common set of food security questions for use in diverse cultural and linguistic settings.
