Evaluation of the Domestic Violence Homicide Prevention Demonstration Initiative: Collaboration Surveys, 5 U.S. states, 2015-2019

The National Institute of Justice (NIJ) and the Office for Violence Against Women (OVW) has evaluated the implementation process and impact of the U.S. Department of Justice's Domestic Violence Homicide Prevention Demonstration Initiative. The evaluation was conducted by a team of investigators from Yale University and Michigan State University. The demonstration initiative (DI) included 3 implementation sites (California, North Carolina and Illinois). In addition, 2 comparison or typically implementing sites (Michigan and Tennessee) were included in the evaluation. The sites implemented the Lethality Assessment Program (LAP) developed by the Maryland Network Against Domestic Violence. A web-based survey was used to gather data to assess changes in collaboration within each of the sites. Respondents from agencies providing support to victims of domestic violence and their offenders reported on their level of collaboration with other named agencies in their networks at two or three time points. Data sets are at the site level. Social network analysis was conducted to assess how the network changes over time.
