This project highlights that research continues to link a father’s positive involvement in the family to outcomes that reflect children’s well-being, and when child welfare agencies successfully engage fathers in their children’s cases, the agencies create a connection that can also improve children’s outcomes. Relatively few studies have addressed the specific benefits of involving paternal relatives, but support from extended family is linked to children’s well-being. Even though involving fathers in child welfare services can have a positive impact on their children’s well-being and there is a deepening focus on parent engagement in child welfare, fathers are not well engaged in child welfare services. This project uses the Breakthrough Series Collaborative (BSC) to improve placement stability and permanency outcomes for children by engaging their fathers and paternal relatives, and includes promising practices and implementation strategies to help organizations improve this practice.
