Retrospective research concepts
- Retrospective research refers to the research methods based on the present results and back to the past. This research method has its advantages due to less restrictive conditions, but its drawback is that the current physical and mental state of the subject will affect the authenticity and accuracy of the past data report. For example, a person with a serious illness often attributes the current condition to his past, and as a result may report more previous negative life events, and the estimation of the severity of the negative event may also be too high, resulting in False positive results of life events related to the current disease.
Introduction to Retrospective Research Methods
- The subjects of the retrospective study were selected and grouped according to their characteristics or exposure at a certain point in time, and then traced back from the existing records from that time to a later point in time or until the time of the study. Within each case. This work is equivalent in nature to the follow-up of a prospective study from a certain point in the past, but what is actually done is to investigate the fait accompli in the past. At this time, exposure and disease or death have become facts. Follow-up is to look for the results of new samples during the process. It is a research method from "effect" to "cause". [1]
