To test whether you are depressed, you can use a clinical scale to measure your depression, but it is important to note that the scale is only used as a reference and cannot be used as a criterion to confirm the diagnosis of depression. The commonly used clinical depression scale is the Self-Rating Scale for Depression (SDS), which provides a general understanding of one’s depressive state. Therefore, clinically, when the manifestation of severe depression is measured, it is possible to seek the help of a doctor in psychology or psychiatry, and only after the doctor synthesizes the development and changes of depression, as well as the psychiatric examination, the content of the scale measurement, the diagnosis of exclusion and other related tests, a comprehensive assessment is given to confirm the diagnosis of depression. Therefore, the diagnosis of depression should be made under the guidance of a doctor, and once the diagnosis of depression is confirmed, systematic and standardized treatment, such as medication, psychotherapy and physical therapy, is required.
