RESUMO
Family violence, including child maltreatment (CM) and intimate partner violence (IPV), plagues far too many American families, particularly those in low-income communities. CM and IPV are intertwined and impose a significant emotional, health and financial burden on children and families and an economic burden on our country. Although these and other forms of violence are influenced by shared risk factors across the socioecological spectrum, prevention efforts typically intervene on a single type of violence at a microsystem level via individual or family intervention. Research is needed to identify policies operating at macrosystem levels that reduce, at scale, multiple forms of violence affecting children. In this paper, we propose a three-step theory of change through which health insurance expansions might reduce rates of CM and IPV, using Medicaid expansion as an exemplar. The proposed framework can inform research examining the link between health insurance and the primary prevention of CM and IPV.
