In collaboration with the National Institute of Justice (NIJ) and the Office for Violence Against Women (OVW) the Yale University team will evaluate the implementation process and impact of the U.S. Department of Justice's Domestic Violence Homicide Prevention Demonstration Initiative. This evaluation seeks to draw critical findings and potential lessons from the combined experience of the sites including: 1) how the models work in different communities; 2) the barriers and facilitators to implementing the models; and 3) outcomes of the model delivery. The evaluation team will also disseminate the findings with the goal of informing replication.
