If you feel that you are experiencing some mental problems, you can identify and screen for them in the following ways Screening can be done with simple self-assessment scales, which commonly include the Symptom Self-Rating Scale, also known as the SCL90 scale. The screening of 90 self-assessment questions provides a rough estimate of your mental status. If the results deviate from the normal values, it is recommended to go to the hospital for further screening to clarify whether you have a mental illness. If the patient feels that his or her mental state is so bad that he or she can no longer perform normal work or even live a normal life, he or she should immediately go to the hospital for an assessment and a psychiatric consultation with a professional doctor. Because the scale can only be used as scientific research and preliminary assessment, to get a final and definite diagnosis, you still need to have a regular doctor to conduct a psychiatric consultation to know. Therefore, if you feel that you have a mental problem and your symptoms are not serious, you can first take a self-assessment of your symptoms. If you feel that your symptoms are more serious, go to the hospital immediately and seek help from a regular doctor.
