The examination of psychological disorders is mainly carried out by talking to a professional doctor. Unlike somatic diseases, such as cerebral thrombosis, fractures, tumors, inflammation, etc., a definitive diagnosis cannot be made with the help of auxiliary tests such as imaging and laboratory tests. For those who can feel the presence of their problems, feel distressed and actively seek help, they can talk directly with the doctor who will understand the situation through some professional open-ended questions and make a clear diagnosis based on diagnostic criteria combined with questionnaires and other scales. And some people have emotional or behavioral changes that bring distress and distress to people around them but they do not feel it themselves. In this case, the situation can be reflected truthfully by their guardians, and the doctor should also make a site visit if necessary to get to the bottom of the matter and better help the person concerned. In addition to face-to-face conversations, questionnaires and other examinations of the visitor can be supplemented to help the doctor make an accurate judgment of the visitor’s problems.
