Conditions of effective correctional treatment for reducing recidivism: Focusing on risk principle

Abstract

Research on correctional treatment based on the risk principle (Andrews & Bonta, 2010) has found that the intensity of intervention matched with the risk level of offenders' recidivism is successful to reduce recidivism. However, there is no research dealing with this issue in a non-Western context. The purpose of this study was to examine the validity of the risk principle in rehabilitation for Japanese juvenile delinquents. The sample was 321 Japanese male inmates of the juvenile detention and assessment centers. They were followed for an average of 573 days after discharge to assess recidivism. Among high-risk juvenile delinquents, those who were treated in the juvenile training school showed significantly lower rates of recidivism than those who were placed under community supervision, while among low risk juveniles, there was no significant difference in recidivism between the two treatment conditions. The results indicate that the risk principle is valid for the correctional treatment of Japanese juvenile delinquents, suggesting its cross-cultural universality. Implications for juvenile justice policies and directions for future research are discussed.
