ABSTRACT

Frontline police officers who attend domestic violence incidents face a considerable challenge in effectively determining the extent to which limited police resources should be invested in further assessment and management of a case to ensure safety. Assessing the risk of future family violence has been proposed as a way of deciding which cases police should focus their management efforts on. However, risk assessment based on police judgement alone has been shown to be inaccurate, leading to the use of structured risk assessment instruments in many jurisdictions. This paper reports the results of three separate studies that were designed to assess the reliability, predictive validity and feasibility of one such instrument; the Victoria Police Screening Assessment for Family Violence Risk (VP-SAFvR). The VP-SAFvR is an actuarial tool intended to assist police decision making in family violence cases. The first study indicated that the VP-SAFvR had excellent reliability. The second study, a prospective study of 3963 cases demonstrated moderate predictive validity. The final study, based on surveys and focus groups suggested that the tool was viewed as easy to use by the majority of police surveyed. However, they identified some problems in implementation that could be improved to enhance the feasibility of using such instruments in the field. The results demonstrate that structured risk assessment can be used to assist police decision making in a way that is timely, feasible and reasonably accurate.

在维持家庭暴力的治安中实施循证实践:优先考虑警察应对措施的风险评估工具的可靠性,有效性和可行性

摘要

参加家庭暴力事件的一线警官在有效确定应将有限的警力资源用于进一步评估和管理案件以确保安全的程度方面面临着巨大挑战。提议评估未来家庭暴力的风险,以此作为确定警察应集中精力处理哪些案件的一种方式。但是,仅基于警察判断的风险评估已被证明是不准确的,从而导致在许多辖区使用结构化的风险评估工具。本文报告了三项独立研究的结果,这些研究旨在评估一种此类仪器的可靠性,预测有效性和可行性。维多利亚州警方针对家庭暴力风险的筛查评估(VP-SAFvR)。VP-SAFvR是一种精算工具,旨在协助警察在家庭暴力案件中做出决策。首次研究表明,VP-SAFvR具有出色的可靠性。第二项研究是一项对3963例病例的前瞻性研究,显示了中等的预测有效性。根据调查和焦点小组进行的最终研究表明,大多数接受调查的警察都认为该工具易于使用。但是,他们确定了实施中的一些问题,可以改进这些问题,以增强在现场使用此类工具的可行性。结果表明,结构化风险评估可用于以及时,可行和合理准确的方式帮助警察做出决策。一项对3963例病例的前瞻性研究显示出中等的预测有效性。根据调查和焦点小组进行的最终研究表明,大多数接受调查的警察都认为该工具易于使用。但是,他们确定了实施中的一些问题,可以改进这些问题,以增强在现场使用此类工具的可行性。结果表明,结构化风险评估可用于以及时,可行和合理准确的方式帮助警察做出决策。一项对3963例病例的前瞻性研究显示出中等的预测有效性。根据调查和焦点小组进行的最终研究表明,大多数接受调查的警察都认为该工具易于使用。但是,他们确定了实施中的一些问题,可以改进这些问题,以增强在现场使用此类工具的可行性。结果表明,结构化风险评估可用于以及时,可行和合理准确的方式帮助警察做出决策。他们确定了实施中的一些问题,可以改进这些问题,以增强在现场使用此类工具的可行性。结果表明,结构化风险评估可用于以及时,可行和合理准确的方式帮助警察做出决策。他们确定了实施中的一些问题,可以改进这些问题,以增强在现场使用此类工具的可行性。结果表明,结构化风险评估可用于以及时,可行和合理准确的方式帮助警察做出决策。
