Preventing Repeat Incidents of Family Violence: A Reanalysis of Data From Three Field Tests in Manhattan [New York City], New York, 1987, 1995-1997

In the mid-1980s New York City officials developed an intervention program, the Domestic Violence Intervention Education Project (DVIEP), to reduce repeat incidents of family abuse. The program posited that repeat victimization would decline as victims extracted themselves from self-defeating relationships or by working with social services and criminal justice staff to develop strategies to end the abuse while staying in the relationship. The purpose of this study was to evaluate the effectiveness of the DVIEP model in reducing repeat instances of family violence. Between 1987 and 1997, three separate, randomized field experiments in New York City's public housing projects evaluated whether or not the DVIEP program reduced the rate of subsequent victimization. All three studies tested the same intervention model: persons who reported family violence to the police were randomly assigned to receive or not to receive a follow-up visit from a domestic violence prevention police officer and a social worker. For this study, researchers concatenated the micro data from the 3 experiments into a single, 1,037 case dataset that contains identical treatment and control measures, and nearly identical outcome measures. Of the 1,037 total cases in the study, 434 are from the 1987 Domestic Violence Study, 406 are from the Elder Abuse study, EFFECTIVENESS OF A JOINT POLICE AND SOCIAL SERVICES RESPONSE TO ELDER ABUSE IN MANHATTAN [NEW YORK CITY], NEW YORK, 1996-1997 (ICPSR 3130), and 197 are from the Domestic Violence Arrestee Study in Manhattan's Police Services Area 2 (PSA2). The resulting data collection contains a total of 31 variables including which study (1987 Domestic Violence Study, Elder Abuse Study, or Domestic Violence Arrestee Study) the respondent participated in, whether the respondent was part of the experimental group or the control group, whether the respondent received public education or a home visit by a DVIEP team, the number of DVIEP services the respondent used, and whether the respondent completed a final interview with a DVIEP team after six months of tracking. Additionally, variables include the victim's age, whether the perpetrator of domestic abuse was a romantic partner of the victim, the number of incidents reported to the police, the Conflict Tactics Scale (CTS) violence score, and the number of days until the first new incident of domestic abuse.

20世纪80年代中期，纽约市政府官员推出了一项干预项目——家庭暴力干预教育项目（Domestic Violence Intervention Education Project，DVIEP），旨在减少家庭暴力的重复发生。该项目假设，若受害者摆脱自我耗竭的亲密关系，或是联合社会服务与刑事司法人员制定策略，在维持关系的同时终止虐待行为，重复受害的情况将会减少。本研究旨在评估DVIEP模型在降低家庭暴力重复发生风险方面的有效性。1987年至1997年间，纽约市公共住房项目中开展了三项独立的随机现场实验，用以检验DVIEP项目是否降低了后续受害率。三项实验均采用同一干预模型：向警方报案家庭暴力的受害者会被随机分配至干预组或对照组，干预组将接受家庭暴力防控警官与社会工作者的后续访视。本研究中，研究者将三项实验的微观数据整合为一份包含1037个案例的数据集，该数据集具备一致的干预与对照测量指标，且结果变量高度统一。在全部1037个案例中，434个来自1987年家庭暴力研究，406个来自1996-1997年曼哈顿地区老年人虐待研究《1996-1997年纽约市曼哈顿针对老年人虐待的警方与社会服务联合响应有效性》（ICPSR 3130），另有197个来自曼哈顿第2警务区（PSA2）的家庭暴力被捕者研究。本数据集共包含31项变量，涵盖受访者参与的研究类型（1987年家庭暴力研究、老年人虐待研究或家庭暴力被捕者研究）、受访者所属组别（实验组或对照组）、受访者是否接受公共教育或DVIEP团队的家庭访视、受访者使用的DVIEP服务数量，以及受访者是否在为期6个月的追踪后完成了DVIEP团队的最终访谈。此外，变量还包括受害者年龄、家庭暴力施害者是否为受害者的亲密伴侣、向警方报案的虐待事件数量、冲突策略量表（Conflict Tactics Scale，CTS）暴力得分，以及首次出现新家庭暴力事件的间隔天数。
