Book excerpt: How can we prevent intimate partner violence (IPV)? And how do we define and measure “success” in preventing it? This book brings together researchers and practitioners from a wide range of fields to examine innovative strategies and programs for preventing IPV. The authors discuss evaluations of current prevention efforts, paying particular attention to underserved groups, including racial and ethnic minorities, immigrants and refugees. Among the issues addressed are primary prevention programs that target adolescents and young adults, strategies designed to engage men and boys, IPV screening in different settings, the impact of the criminalization of IPV on minority populations, restorative justice programs, interventions for women who use violence, and innovative shelter programming to prevent re-victimization. The volume concludes by identifying the gaps in knowledge about effective prevention and highlighting the most promising future directions for prevention research and strategies.
