The Belau Family Health and Safety Study (FHSS) aimed at obtaining reliable data on the prevalence and types of violence against women (VAW) in Palau. The study also sought to document the associations between partner violence and health issues and other outcomes, as well as to identify risk and protective factors for partner violence. The Ministry of Health carried out the study with financial support from the Australian Government’s Department of Foreign Affairs and Trade (DFAT), and financial and technical support from the United Nations Population Fund (UNFPA). The methodology of the study builds on the WHO Multi-Country Study on Women’s Health and Domestic Violence Against Women, which combines quantitative and qualitative components. The WHO methodology adheres to international ethical and safety standards for research on VAW and ensures data comparability across countries.
