Taiwan passed Domestic Violence Prevention Law in 1998. However, it was found that the judges rarely transferred the abusers for pre-sentence assessment, and it caused that rare abuser sentenced to clinical treatment in protection order, which jeopardized the original purpose of this law to prevent re-abuse in the future. This experimental project tried to re-organize the whole procedure. It included the following elements: police officer assisted the victim to fill risk assessment scale while report the case, new telephone-contact brief assessment by clinician, clinicians wrote the report and treatment suggestion for judge, the judge sentenced the treatment by referring the brief assessment report, supervising contacts of various density made by the police officer and social workers, supervisor trained enough treatment practitioners for providing treatment, and network meeting opened every two months. The advantages of this project were found as the following: better communication among related workers, more abusers sentenced to treatment by judges, more supervising contacts were made by police officers and social workers, more abusers participated treatment to learn relapse prevention and self control. The project also found abnormal domestic abuse reporting cases, such as 4.8% of victims maliciously abused this law and 1.1% of victims had serious mental illness to make the faulty report.
