The Impact of Improving Access to Support Services for Victims of Domestic Violence on Demand for Services and Victim Outcomes
通过随机对照试验，发现帮助家暴受害者获取非警方支持服务使提供证人证言的比例下降22%，但未显著改变逮捕定罪或未来暴力，同时增加了非警方服务使用并降低了未来受害风险。
We conducted a randomized controlled trial of an intervention designed to assist victims of domestic violence in accessing nonpolice support services. The intervention led to a 22 percent decrease in the fraction of victims providing a witness statement to police. Witness statements are an important piece of evidence and a key input in the prosecution of perpetrators. Despite this, we do not find a significant change in perpetrator arrests and convictions or in reported future violence. Survey responses provide evidence of an increase in nonpolice service use and a reduction in future victimization risk, but also a potential decrease in short-run well-being.
