The Development of a Validated Scale of Household Water Insecurity in High-Income Countries: HWISE-HIC

by Dr. Justin Stoler

New metrics of household water insecurity have been validated for low- to middle-income countries, but it is unclear how these measurements apply to the experiences of people living in high-income countries. This project aims to develop and validate a novel metric for household water insecurity experiences in high-income countries (HWISE-HIC) using a retrospective, cross-sectional design. We present the protocol for the development and validation of a novel household water insecurity scale for high-income countries to address this scientific need, including key steps in the process: (1) item development through literature and theory; (2) pre-testing of items and expert review; (3) scale development and item reduction; and (4) scale validation. We also present preliminary results from our community-based data collection and a national online survey that oversampled US adults from low-income households and racial/ethnic minority groups. This study will develop a novel metric of water insecurity experiences for households in high-income countries with implications for resource allocation, structural interventions, public health planning, and reductions in inequalities.
