ObjectiveTo understand the relationship between post-traumatic stress disorder (PSTD) and perceived stress in suspected coronavirus disease 2019 (COVID-19) patients quarantined in hospital.MethodsA cross-sectional study of 93 suspected COVID-19 patients in one of grade-A tertiary hospital in Southwest China was carried out to evaluate the incidence of perceived stress and post-traumatic stress symptoms among these patients using the standardized Perceived Stress Scale-10 (PSS-10) and PTSD Checklist-5 (PCL-5), respectively. Pearson correlation was used to analyze the correlation between PCL-5 and PSS-10 scores.ResultsTotal PSS-10 and PCL-5 scores were 16.7±5.2 and 17.0±11.6 in 93 suspected COVID-19 patients, respectively. Positive correlations between PSS-10 and PCL-5 scores were detected (Pearson’s r=0.722, P=0.000).ConclusionsThe occurrence and development of PSTD of suspected COVID-19 patients have the relationship with the early perceived pressure. It suggests that medical staff should identify and intervene the perceived pressure level of patients who are under quarantine as suspected COVID-19 early and effectively, so as to reduce the occurrence of PTSD.
