Limitations
This study presents several limitations. Firstly, the sample size is
small. Because the crisis outbreak was still ongoing during the research
period, we should allow medical staff to spend more time on patients or
rest. In addition, the study was carried out during 10 days in the late
stage of fighting epidemic in Wuhan, China, while the early, middle
stage and longitudinal follow-up were not considered. Thus we couldn’t
investigate the dynamic psychological change. Further studies with
larger sample size and observation of multiple time point are warranted.
