Several brief screening measures for youth risk to reoffend have been developed; however, these measures have been tested primarily in high-income English-speaking countries and their predictive validity is limited. A recent study proposed a screening strategy using a combination of seven items from the Youth Level of Service/Case Management Inventory (YLS/CMI). Predictive validity for this strategy was better than that reported in studies of previously developed screening tools. In the current study, the predictive validity of this strategy was examined across samples of justice-involved youth from two countries: Canada (N = 196) and Portugal (N = 2,348). The full version of the YLS/CMI was completed and recidivism data were collected over a 2-year period. Results support the predictive validity of this strategy, with area under the curve (AUC) values (.69–.74) very similar to those found in the full version in each country, both in the full samples, and for both genders.

已经制定了几项简短的筛查措施，以降低青年人再次犯罪的风险；但是，这些措施主要在高收入英语国家/地区进行了测试，其预测有效性有限。最近的一项研究提出了一种筛选策略，该策略结合了青年服务水平/案例管理清单（YLS / CMI）中的七个项目。此策略的预测有效性优于先前开发的筛选工具的研究报告。在当前的研究中，对来自以下两个国家的涉及司法公正的年轻人的样本进​​行了研究：加拿大（N = 196）和葡萄牙（N= 2,348）。YLS / CMI的完整版本已完成，并且在两年的时间内收集了累犯数据。结果支持了该策略的预测有效性，曲线下面积（AUC）值（.69-.74）与每个国家的完整版中的全部样品和性别均非常相似。
