This study aims at investigating the association between the supervision techniques of probation officers an recidivism of probationer in South Korea. In particular, the present study has purposes of examining the relationship between types of supervision of officers and offenders under Electronic Monitoring System. After newly released from prison, numerous offenders struggle with complicated social problems such as stigma, lower social support, drug abuse, and mental disorder(Chiricos et al., 1972; Stephensmeier & Kramer, 1980; Bahn & Davis, 1991, Cullen, 1994; Lurigio, 1996, 1996; Peatersilia, 2003; Funk, 2004; Tewksbury, 2005). To solve these problems, probation officers have made an tremendous level of effort to provide appropriate probation supervision and support for the offenders who want to adjust to community. This present research study focused on investigating the association between three different types of community supervision methods and recidivism rates of offender by using 975 probationers who were under Electronic Monitoring System from 2008 to 2010. According to the hierarchical logistic regression analysis, there is a statistically significant relationship between “Welfare Worker Method” and probationer's recidivism(B=0.550, P<.001). Furthermore, there is a statistically significant association between “Punitive Officer Method” and probationer's recidivism(B=1.372, P<.001). Further policy implications will be discussed.
