Abstract
This study examined the effectiveness of Specialised Sex Offender Treatment Programmes (SSOTP) provided at correctional facilities in Japan. Because sexual offences are serious crimes that invoke public concern, providing effective treatment for sex offenders is crucial. However, there is insufficient evidence on the effectiveness of this treatment for sex offenders, particularly in Japan. Therefore, this study investigated whether receiving SSOTP reduced general and sexual recidivism. All participants were followed up for three years from the day when they were released from correctional facilities in Japan. The results revealed that the rate of sexual recidivism in participants who received SSOTP (15.0%, n = 1,444) was significantly lower than that of those who did not (22,5%, n = 324). Receiving SSOTP was also associated with reduction in general recidivism (treated offenders: 27.3%; untreated offenders: 38.0%). Further research utilizing more robust methodologies is warranted for more rigorous corroboration.
