Core Tip

Core tip: In 2005, the Medical Treatment and Supervision Act was enforced in Japan. In this scheme, offenders with mental disorders are hospitalized for assessment (HfA) to determine their treatment. We aimed to clarify the components of HfA and the management changes from the beginning of the scheme to the present. We obtained approximately a half of whole contemporary cases of HfA in the 2013 survey, and then compared the data to those in the 2007 study. The comparison revealed some changes in the HfA cases. This study clarified the improvement of HfA management, and remained some structural problems as well.
