Clinicians mainly make judgments based on the following scales ⑴Experience scale – mainly refers to the examiner’s experience (actual work experience and experience), and the examiner makes judgments about whether the examined person’s psychological state is normal or abnormal based on his or her experience. ⑵ Social adaptation scale – living in a specific social environment, under normal circumstances human behavior is always in harmony with the environment, thus maintaining a state of psychological equilibrium. Such as social norms, social requirements, moral norms formed by the social norm. Those who conform are normal, those who do not conform are abnormal. ⑶ Medical scale – mainly refers to the biomedical scale (etiological and symptom criteria) (or diagnostic criteria for a particular disease). That is, the abnormality of the mental state is treated as if it were a physical disease. It is a more objective scale, but a large number of psychological abnormalities cannot be measured and judged from the biomedical scale. ⑷Statistical scale – the application of statistical methods to clearly show the norm, any phenomenon that deviates from the norm can be regarded as abnormal. For example, clinicians often ask patients to do psychological tests and assessments. Each scale of psychological diagnosis has a certain basis and a certain value, but each scale cannot solve all problems perfectly alone, and thus they should be seen as means to complement each other in order to make a more correct diagnosis of the psychological state.
