The Samoa Family Health and Safety Study (SFHSS) is a component of the larger Pacific Multi-site Study of the Effects of Violence Against Women on Family Health and Safety, which is a joint research initiative of the Secretariat of the Pacific Community (SPC) and the United Nations Population Fund (UNFPA). The Multi-site study follows the methodology of the World Health Organization (WHO) Multicountry Study of Women’s Health and Domestic Violence, and uses questionnaires based on those developed by WHO. The Pacific Multi-site Study was designed to: provide detailed information on the prevalence and frequency of different forms of violence in families (defined to include relationships between de facto partners); examine risk and protective factors at the household and community level; document the health and legal consequences of domestic violence; explore strategies and interventions used by victims, families, and communities; and assess the impact of attitudes on the prevention and intervention of violence.
