Persons subject to domestic violence restraining orders (DVROs), known as respondents, are generally prohibited from possessing firearms. Efforts to enforce that prohibition have not been evaluated. The study objective was to determine whether associations exist between risk of incident arrest among DVRO respondents and 1) respondents' access to firearms, and 2) law enforcement recovery of firearms from respondents with access to them.
This was an observational study of 2,972 DVRO respondents in San Mateo County, California, 525 of whom were linked to firearms by standardized screening procedures. Enrollment occurred from May 2007 to June 2010 and follow-up through September 2010. Follow-up began when DVROs were served (or when issued if no date of service was available); median duration was 689 days. Principal exposures were access to firearms and, for subjects with access to firearms whose DVROs were served, contact by law enforcement personnel to recover those firearms. Main outcome measures were 1) incidence of arrest; 2) relative risk for arrest, adjusted for age, sex, prior criminal history, and duration of follow-up, assessed using logistic regression.
Respondents linked to firearms were older than others and were more likely to have a history of prior arrest (49.7 % and 37.3 %, p < 0.0001). The incidence of arrest was 20.6 % for respondents linked to firearms and 21.1 % for others (p = 0.78). In multivariate models, access to firearms was associated with a modest, generally not statistically significant, decrease in risk for incident arrest. Among respondents who were linked to firearms and whose restraining orders were served, no statistically significant association existed between firearm recovery and risk for incident arrest.
In this small study of DVRO respondents, findings are inconclusive for an association between access to firearms or firearm recovery and risk of incident arrest. Controlled trials on larger populations are indicated.
受家庭暴力限制令(DVROs)约束的人,即被申请人,通常被禁止持有枪支。执行该禁令的努力尚未得到评估。本研究的目的是确定DVRO被申请人的事件逮捕风险与以下两个因素之间是否存在关联:1)被申请人获取枪支的情况;2)执法部门从有枪支的被申请人处收缴枪支的情况。
这是一项对加利福尼亚州圣马特奥县2972名DVRO被申请人的观察性研究,其中525人通过标准化筛查程序与枪支相关联。研究从2007年5月至2010年6月进行招募,并随访至2010年9月。随访从DVRO送达时(或无送达日期则从发布时)开始;中位持续时间为689天。主要暴露因素为获取枪支情况,对于有枪支且DVRO已送达的受试者,为执法人员接触以收缴这些枪支的情况。主要结局指标为:1)逮捕发生率;2)经年龄、性别、既往犯罪史和随访持续时间调整后的逮捕相对风险,使用逻辑回归进行评估。
与枪支相关联的被申请人年龄比其他人更大,且更有可能有过被捕历史(分别为49.7%和37.3%,p< 0.0001)。与枪支相关联的被申请人的逮捕发生率为20.6%,其他人为21.1%(p = 0.78)。在多变量模型中,获取枪支与事件逮捕风险适度降低相关,但通常无统计学意义。在与枪支相关联且其限制令已送达的被申请人中,枪支收缴与事件逮捕风险之间不存在统计学上的显著关联。
在这项对DVRO被申请人的小型研究中,关于获取枪支或枪支收缴与事件逮捕风险之间的关联,研究结果尚无定论。表明需要对更大规模人群进行对照试验。
