We seek to address current limitations of forensic risk assessments by introducing the first mobile, self-scoring, risk assessment software that relies on neurocognitive testing to predict reoffense. This assessment, run entirely on a tablet, measures decision-making via a suite of neurocognitive tests in less than 30 minutes. The software measures several cognitive and decision-making traits of the user, including impulsivity, empathy, aggression, and several other traits linked to reoffending. Our analysis measured whether this assessment successfully predicted recidivism by testing probationers in a large urban city (Houston, TX, United States) from 2017 to 2019. To determine predictive validity, we used machine learning to yield cross-validated receiver-operator characteristics. Results gave a recidivism prediction value of 0.70, making it comparable to commonly used risk assessments. This novel approach diverges from traditional self-reporting, interview-based, and criminal-records-based approaches, and can also add a protective layer against bias, while strengthening model accuracy in predicting reoffense. In addition, subjectivity is eliminated and time-consuming administrative efforts are reduced. With continued data collection, this approach opens the possibility of identifying different levels of recidivism risk, by crime type, for any age, or gender, and seeks to steer individuals appropriately toward rehabilitative programs. Suggestions for future research directions are provided.
我们试图通过引入首款基于神经认知测试来预测再犯的移动、自动评分风险评估软件,来解决当前法医风险评估的局限性。这项评估完全在平板电脑上运行,通过一套神经认知测试在不到30分钟内测量决策能力。该软件测量用户的几种认知和决策特征,包括冲动性、同理心、攻击性以及其他与再犯相关的特征。我们的分析通过在2017年至2019年期间对美国得克萨斯州休斯顿市的缓刑犯进行测试,来衡量这项评估是否成功预测了累犯情况。为了确定预测效度,我们使用机器学习得出交叉验证的接收者操作特征曲线。结果得出的累犯预测值为0.70,使其与常用的风险评估相当。这种新颖的方法不同于传统的自我报告、基于访谈和基于犯罪记录的方法,还可以增加一层防止偏见的保护,同时提高预测再犯的模型准确性。此外,消除了主观性,减少了耗时的行政工作。随着持续的数据收集,这种方法有可能按犯罪类型、年龄或性别识别不同程度的累犯风险,并试图引导个人适当地参与康复项目。文中还提供了未来研究方向的建议。
