The most important means of assessment of mental illness in the world is to judge the patient’s condition through systematic consultation and mental status examination by professional psychiatrists, in which the doctor has to understand the cause of the patient’s illness, the process of onset of the disease, the time of the disease, as well as some specific manifestations of the disease, as well as some of the patient’s personal experience, family situation, and so on. Therefore, if there is a schizophrenic patient in the family, it is necessary to cooperate with the doctor for a systematic examination, which is conducive to the doctor’s judgment of the patient’s condition. The second way to measure the patient’s condition is through some professional psychological assessment scales. Psychological assessment is also a common scale all over the world, and there are many varieties of these scales, so the choice should be assessed through the judgment of professional doctors.
