Evidence-Based Programs

Children Exposed to Violence Evidence-Based Programs Database

Happy Children For a definition and information on children’s exposure to violence click here.

The Children Exposed to Violence (CEV) Database is a joint project of the Safe Start Center and CrimeSolutions.gov website funded by the Department of Justice. The database uses rigorous research to inform practitioners and policy makers about what works in services for children exposed to violence. The menus on the right allow you to search the database of programs. You can see the details and descriptions for any of the programs by clicking on their titles in the search results.

Evidence Ratings

Evidence Rating One Study Icon* More than One Study Icon* Description
Effective effective icon effective multi-study icon Programs have strong evidence indicating they achieve their intended outcomes when implemented with fidelity.
Promising promising icon promising multi-study icon Programs have some evidence indicating they achieve their intended outcomes. Additional research is recommended.
No Effects no effects icon no effects multi-study icon Programs have strong evidence indicating that they did not achieve their intended outcomes when implemented with fidelity.

*A single study icon is used to identify programs that have been evaluated with only one study. A multiple studies icon is used to represent a greater extent of evidence supporting the evidence rating. The icon depicts programs that have more than one study in the evidence base demonstrating effects in a consistent direction.

Resources for Implementation

Resources for Implementation

Implementation of evidence-based programs refers to the integration of research findings into program policy and practice. Successful implementation is based on an understanding of the behavior of staff and clients as a key variable in the sustainable selection, adoption, and execution of evidence-based interventions. Resources included in this section are designed to address major barriers that impede effective implementation of evidence-based programs and, ultimately, to improve outcomes for children and families.
