As gender-based violence (GBV) surged during the COVID-19 pandemic, the 65th session of the Commission on the Status of Women (CSW65) called for member states, civil, and other stakeholders to consider the specific needs of women and girls in COVID-19 response and recovery efforts. Psychology provides scientific knowledge to help answer this call. Despite existing global guidance and psychological research to mitigate GBV, COVID-19 presents new challenges for consideration. This article summarizes existing GBV guidance/research and COVID-19 considerations, uses an illustrative case study to describe Puerto Rico's application of GBV guidance/research during COVID-19, and provides preliminary policy and practice recommendations.
