Family violence, including intimate partner violence (DV), child abuse, and elder abuse, often perpetuates across generations and occurs simultaneously. This phenomenon is referred to as Family Poly-victimization, where victims may become perpetrators (and vice versa), creating a highly complex and chaotic issue. When family poly-victimization is present, intervention targeting only a single form of violence does not address the root cause of the family’s issues. This can lead to an escalation of violence, with the most vulnerable family members (such as children) potentially losing their lives. Therefore, to prevent and resolve family poly-victimization, it is essential to build a support system that transcends the boundaries of each violence specialty. With this in mind, we are advancing research on family poly-victimization.
■ Development of a Scale to Measure Family-polyvictimization
We have developed a simplified scale for measuring family poly-victimization, the Japanese version of the Family Poly-victimization Scale (FPS-J). This scale is a Japanese adaptation of the tool originally developed by a long-time collaborator, Edward Chan Ko Ling (Hong Kong Polytechnic University). The FPS-J is designed to assess the presence and extent of intimate partner violence (DV), child abuse, and elder abuse within families. It contains 17 items, making it easy to use for parents with children under 18. In 2020, we validated the Japanese version of the FPS through a survey conducted with 483 parents on family poly-victimization.
