The Household Food Insecurity Access Scale (HFIAS) is a tool designed to measure household food insecurity, particularly focusing on access to sufficient food. This guide, published by FHI 360 in August 2007, provides a detailed methodology for implementing the HFIAS, including questionnaire adaptation, interviewer instructions, and data tabulation. The HFIAS consists of 18 questions that assess various aspects of food insecurity, such as anxiety, uncertainty, and dietary choices. The guide outlines a two-step process for adapting the questionnaire to local contexts, involving reviews with key informants and refinement with respondents. It also provides specific instructions for conducting interviews and interpreting the data, which can be used to create indicators of food insecurity prevalence and severity. The HFIAS is intended to help programs monitor and evaluate their impact on household food security, particularly in developing countries.The Household Food Insecurity Access Scale (HFIAS) is a tool designed to measure household food insecurity, particularly focusing on access to sufficient food.
