The Ohio Youth Assessment System-Disposition Tool (OYAS-DIS) is a juvenile risk assessment that is used in numerous states and jurisdictions to assess criminogenic risk of juvenile offenders. Still, there is little published research on the predictive validity of the tool. The purpose of the current study was to examine the predictive validity of OYAS-DIS, with a specific focus on understanding prediction of recidivism across racial and gender subgroups. The sample consisted of 4,383 youth that received a court petition in a single large Midwestern county juvenile court. The findings indicated that the OYAS-DIS was a statistically significant predictor of recidivism across all racial and gender subgroups. However, there was statistically significant variation in predictive validity across subgroups. For instance, the tool was a statistically significantly better predictor of recidivism for White males as compared to Black male youth. There was also statistically significant variation in the predictive validity of certain domains (e.g., juvenile justice history) on the OYAS-DIS across racial and gender subgroups. Implications of research favor the use of the OYAS-DIS to predict recidivism for adjudicated juveniles.

俄亥俄州青年评估系统处置工具（OYAS-DIS）的验证：种族和性别差异的检验

俄亥俄州青少年评估系统处置工具（OYAS-DIS）是一种青少年风险评估工具，在许多州和辖区中都使用该工具来评估青少年罪犯的犯罪风险。但是，关于该工具的预测有效性的研究很少。本研究的目的是检验OYAS-DIS的预测效度，特别侧重于理解跨种族和性别亚组的累犯预测。样本包括4,383名年轻人，他们在中西部一个大型县青少年法院中接受了法院请愿。研究结果表明，OYAS-DIS在所有种族和性别亚组中都是累犯的统计显着预测因子。但是，各亚组之间的预测效度在统计学上存在显着差异。例如，与黑人男性相比，该工具在统计学上可以更好地预测白人男性的再犯。在OYAS-DIS上，不同种族和性别亚组的某些领域（例如，少年司法史）的预测有效性也存在统计学上的显着差异。研究的意义在于使用OYAS-DIS来预测少年犯的再犯情况。
