In the field of psychiatric care, shared decision making has become important and specific devices are required in its practice. We created shared decision making tools called "Question Prompt Sheet" and "Medical Care Supplement". A perspective of advocacy is required as the basis for shared decision making. Housing First is one of the recent paradigm shifts in mental health services. It provides housing and medical treatment separately and independently. Housing is a basic human right and must not be lost, even without medical treatment. Even if the patient refuses to make a shared decision with the doctor, human rights, including housing, must not be violated.
