　　　　　Nation-wide psychiatric hospital accreditation (PHAP) was initiated by the Department of Health in 1985. It has been carried out every three years since its inception in 1985, namely, in 1985, 1988, 1991, 1994, and 1997 respectively. All the data collected in the accreditation process are based on the specifically designed schedules by the accreditation committee of the Department of Health. All the accreditation is on peer-evaluation basis. This study reports major findings from the PHAP carried out in the past five respective key years. The results of study show there are slight changes in the number of hospitals participated, number of evaluators, the specific areas, programs, treatment modalities, and the items evaluated, and the measures taken for those hospital which do not meet the requirement of the accreditation committee. Overall the changes are directed toward the improvement of the program based on the demand for mental health care at the specific key years of accreditation, and on the results of the prior accreditation. The study found that the PHAP has had significant impacts on the improvement of mental health care in terms of: 1) increase in psychiatric personnels, in treatment facilities particularly for community care, and in psychiatric unit of general hospital settings; and 2) intensification of quality assurance measures in various aspects of care. Suggestions are made to further improve the procedures of the accreditation in order to meet with the increasing demand for mental health care of the nation.
