Research Abstract

For the purpose of contributing to establishi useful treatment system for mentally disordered offenders (MDOs), following three studies were carried out.
1. A follow-up study on 946 MDOs, who were registered in 1980 as irresponsibility or diminished responsibility for their criminal act at the Ministry of Justice.
2. An analysis of data on 1125 MDOs registered in 1994 at the Ministry of Justice.
3. A comparative study of law and treatment system for mentally disordered offenders between UK and Japan.
From these three studies, following findings seems to be important.
The majority (about 90%) of mentally disordered offenders were discharged by the prosecutors without prosecution by the reason of irresponsibility or diminished responsibility for their criminal act. But such a treating system without security measures is defective, sometimes resulting in serious problems as follows.
(1) In the process of the prosecutor's decision, sometimes psychiatric evaluation can not be done adquately, and some dangerous cases may be discharged directly to the community without hospitalization.
(2) Even after the MDOs are hospitalized, some cases are discharged so early by reson of their dangerousness by itself, and then they commit another crimes in the community. We have no useful measures to limit the discharge of dangerous patients, nor any type of probation system for MDOs.
(3) Because we have no special hospital nor special ward for MDOs, we must treat them in the same ward for general mental patients. Such an inadequate situation results in high incidents of inpatient's victimization of violent act in general mental hospitals.
Taking account of these findings, we should make effort to establish useful treatment system for MDOs.
