The final evaluation report of the Greenbook Initiative, examining the process and effects of implementing the Greenbook recommendations on collaboration, systems change, and practice within and across three primary systems (child welfare agencies, domestic violence service providers, and the dependency courts), was completed in 2008. The evaluation was funded by the U.S. Departments of Justice and Health and Human Services. This final evaluation report, authored by the National Evaluation Team, assesses the extent to which the Greenbook implementation activities facilitated cross-system and system change and practice within the three primary systems. Findings of the evaluation show the efforts of the partners, the challenges they faced in carrying out their work, and the changes they were able to bring about in how the systems work to identify and respond to the needs of families and children experiencing the co-occurrence of domestic violence and child maltreatment.
