This report offers a groundbreaking framework for understanding the relationship between community trauma and violence. Until now, there has been no basis for understanding how community trauma undermines both individual and community resilience, especially in communities highly impacted by violence, and what can be done about it. Funded by Kaiser Permanente Community Benefit in Northern California, and based on interviews with practitioners in communities with high rates of violence, the report outlines specific strategies to address and prevent community trauma—and foster resilience—using techniques from those living in affected areas.
