Secondary prevention is also called preclinical prevention (or preclinical prevention), that is, the "three early" preventive measures of early detection, early diagnosis and early treatment in the preclinical stage of diseases.
This level of prevention is to prevent the changes of the disease before or in the early clinical stage through early detection, early diagnosis and appropriate treatment, so that the disease can be found and treated in the early stage, avoid or reduce the occurrence of complications, sequelae and disabilities, or shorten the time of disability.
With the implementation of the strategy of prevention, treatment and rehabilitation of mental illness, the three-level prevention model failed to realize the organic combination of prevention, treatment and rehabilitation. So far, the cause of most mental disorders is unknown. Although primary prevention is "the most proactive", it lacks a clear concept.
Murezak and Hagarty put forward a good conceptual framework, which is operable and enlightening. The main contents are: prevention is only used for intervention before the occurrence of mental disorders, and secondary and tertiary prevention are replaced by treatment and rehabilitation respectively, so that the prevention, treatment and rehabilitation of mental disorders are unified and become a continuum.
